APOLOGY

“The LVVTA has brought it to my attention that statements I have made in relation to it and its employees may have been perceived as defamatory.

I sincerely regret that and apologise for any harm caused. I have taken down the statements identified by the LVVTA of concern to it.

I have strong views about the low volume vehicle certification process and intend in the future to direct my energies into the public inquiry now being held in relation to it.”

ALTHOUGH WE WON THE CASE THE COURT DID NOT AWARD COSTS (18TH MARCH 2016)

The cost to me of defending Mr Johnson’s application for an Injunction to suppress this website has been $8264
Huge thanks to the generous donors who have already contributed $1233.45.

My financial position now is RETIRED, (now my LVV Certification authority has been revoked) and my only income is from National Super.

We WON the case, and Mr Johnson and the LVVTA were DENIED the Injunction that they wanted.
We WON because New Zealand Bill of Rights Act 1990, gives the entitlement to free speech, according to clause 3(b) relating to “by any person or body in the performance of any public function, power, or duty conferred or imposed on that person or body by or pursuant to law”. This clearly applies to Mr Johnson and the LVVTA.
New Zealand Bill of Rights

I then applied to the High Court for costs, although I represented myself, I had extensive legal help from Andrea Halloran, Staff Barrister, of Chris Patterson Barrister Limited

The Judges decision has finally arrived- Judge Woolford has decreed that Costs shall lie where they fall- in other words- I can claim nothing.

My actions were motivated by concern for public safety, and the way the Low Volume system was being run, and aimed at provoking the NZTA into reviewing the Low Volume Vehicle Certification system.
This is now happening, and I await to see the final outcome. I hope that we will have once again a workable Low Volume Vehicle Certification system which will benefit all Vehicle Modifiers.

FREE SPEECH about the dangers of the LVV System has cost me my LVV Certification business, instigated by Mr Johnson, and now, thousands of dollars to defend against Mr Johnson’s allegations of DEFAMATION.

The $7544 debt is a burden in my retirement, and I would appreciate any further donations, no matter how small, and call on everyone who will benefit from new Low Volume Certification system to make a small donation.

NEWS 23rd May 2016 – MR JOHNSON’S LAWYERS HAVE ADVISED THE REGISTRAR OF THE HIGH COURT THAT HE INTENDS TO CONTINUE TO A DEFAMATION TRIAL.

I have served my statement of defense, and there is a Case management Conference on 1st September before a Judge.

Electronic Systems- LVV standard required?

It is no secret that a modern car is becoming a computer on wheels. Critical functions such as braking, steering, chassis dynamics are becoming- not just electronically enhanced, but electronically CONTROLLED by embedded software and electronics systems. Self-driving cars are not yet on New Zealand roads, but they do exist- and most of the enabling technology already exists to varying degrees in most modern vehicles.

Even in STUFF.co.nz Motoring section

Drive-by-Wire is not some futuristic concept. Drivers today are already “driving by wire” far more than they suspect.
Pressing the brake pedal simply starts a process controlled by electronics. The brakes can be applied even without the driver pressing the pedal. Steering on some new models is fly-by wire. Traction control, chassis control all have electronic systems that over-ride the driver.
Disability drive by wire control systems exist and are used in other countries. Using such systems, a driver can control steering, acceleration, braking all from a tiny joy-stick- just like the pilot of a modern jet fighter or airliner! At present there is no process to allow such systems in New Zealand, and they are ruled out by the Low Volume Vehicle Technical Association.
Driving with a joystick

Safety is also a key area that is electronically managed- a possible approaching collision can trigger self-actuating brakes, then arm airbags and seat-belt pretensioners according to tested protocols, activate safety systems in the event of an impact, and even send out an emergency message!

rightcar.govt.nz/protection-during-a-crash

There are International Standards such as ISO 26262 is a Functional Safety standard, titled “Road vehicles – Functional safety”

Modifications impinge on these Electronic Systems in many ways. Examples include seat and seat-belt modifications, disability adaptions, power train, suspension or brake modifications or changes, and structural modifications.

At present, all of this passes below the Low Volume radar- the Low Volume Vehicle Certifier may or may not identify modifications affecting electronic systems, and may or may not make a sensible decisions about whether the modification can be allowed, if so what the affects might be, and what actions should be taken to achieve a reasonably safe vehicle.
The Low Volume Vehicle Certifier may or may not not adequately understand the implications of the modifications.
The Low Volume Vehicle Certifier may or may not not document all of this for his own records, or may not document anything.

There is no guidance available, and no formal processes for a Low Volume Vehicle Certifier to follow.
The contingent liability for injuries of death could be high- It might be argued that a modification affected an electronic system to the extent of causing or contributing to an accident, or that the modification resulted in greater exposure of the vehicle occupants to Injury or death.

A formal process needs to be written as a “Low Volume Vehicle Standard” to ensure optimized vehicle safety, provide guidance to LVV Certifiers, and to protect all parties from potential legal action.
Such a Standard should follow steps such as : 1 Identify, 2 Quantify, 3 Justify, 4 Certify.

Government probe into LVVTA and LVV system

1 Low volume vehicle review welcomed

Low volume vehicle review welcomed

Associate Transport Minister Craig Foss is welcoming a review of the certification process for vehicles built from scratch or modified for a specialised purpose.

The review of low volume vehicle (LVV) certification, initiated by the New Zealand Transport Agency, will be undertaken by Standards New Zealand.

“The LVV certification process is about ensuring vehicles built from scratch or modified for a specialised purpose are safe to be on the road,” Mr Foss says.

The review will begin this month with a scoping phase. This will involve working closely with the vehicle industry, certifiers and others to better understand the strengths of the current system and potential areas for improvement.

“Standards New Zealand brings an independent perspective to this review. I’m pleased it will be seeking feedback from a wide range of people, including those in the industry,” Mr Foss says.

“I’m keen to ensure our LVV certification system enables innovators to utilise new technologies and create opportunities.”

Craig Foss Letter and Standards Association review proposal

Statement from David Seymour, Epsom electorate MP, leader of the ACT party New Zealand, and qualified Engineer

“I have viewed the reports related to UDM’s vehicles, both those prepared by LVVTA and those by professional engineers. It is clear that the LVV process, while ideal for builders of hot rods, kit cars, and the like, does not have the technical expertise to service commercial operators working closer to the frontier of technology.

A review of this system is long overdue. If New Zealand is going to be have the knowledge economy that most of us want, it must have a regulatory environment that works.”

Engineer’s report on faulty wheelchair vehicles haunts NZTA (UN-SAFER JOURNEYS?)

KIVI Kea Carnival conversion

KIVI Kea Carnival conversion

Automotive News

The NZ Transport Agency dismissed a written report from one of its senior engineers warning that millions of dollars worth of wheelchair-access vehicles imported from Italy for use by the Accident Compensation Commission were unsafe and should not be allowed on NZ roads until they were repaired.

Tauranga mechanical engineer Bill Cassidy – a long-time NZTA heavy vehicle certifier – listed seven major faults with the heavily modified vehicles, questioning their life expectancy and saying they could risk life and limb because of “poor workmanship.”

But the NZTA said Cassidy’s findings didn’t justify “further enquiry” because the vehicles had already “been certified in New Zealand under the Low Volume Vehicle Code”(LVV). The code is road-worthiness approval issued by NZTA-appointed LVV certifiers supported and trained by the Low Volume Vehicle Technical Association (LVVTA), a blood relative of the NZTA set up in the late 1990s to certify ‘hobby’ vehicles like hot-rods.

WHAT ENGINEER CASSIDY FOUND …

In the six-plus years since Cassidy’s report – November 10, 2008 – the 90 Italian-modified vehicles have needed on-going repairs at a cost independent engineers have put at hundreds of thousands of dollars on top of the $NZ8.34 million ACC paid for them. Carterton company Braiden International did many of the repairs under a government agency contract, company spokesperson Rochelle Williams confirmed.

The vehicles – 50 long- and 40 short-wheelbase Kia Carnival vans – were converted in 2007-08 by Italian company KIVI and bought by the ACC for its disabled clients. The ACC had cancelled an agreement with its NZ supplier of such vehicles. The long-wheelbase Italian models each cost $NZ94,825 and the short-wheelbase $NZ89,599. KIVI, based near Turin, is a long-time supplier of vehicles for European health agencies.

Cassidy’s findings included:

a modified rear suspension assembly that would (and later did) fracture under stress
a relocated spare wheel that could break loose from its makeshift mounting and become a “missile” inside the cabin – “a lethal situation”
a replacement floor “not made to accepted engineering practice” and made of steel so “flexible” it could “distort upwards into the passenger compartment” in an accident
an airbag system whose inspection module had been “modified” to show it was working when it wasn’t
seatbelts anchored to the floor in a way that didn’t comply with the Low Volume Vehicle Code

ACC COMPLAINS OF CASSIDY’S ‘CONDUCT’ …

Cassidy sent his report to ACC executive John Payne. On November 19, 2008, Cassidy received a reply – not from Payne but NZTA response team manager Dave Robson. Robson wrote that the NZTA had received a complaint from the ACC “about your conduct as a NZTA-appointed heavy vehicle certifier.”

Robson went on … “Further I have read your deed of appointment and have been unable to locate a clause which authorises you to specifically enquire into Low Volume Vehicle certification issues or to demand information from vehicle modifiers or any other persons in relation to Low Volume vehicles.”

Addressing Cassidy’s criticisms of the Italian vehicles Robson wrote, in part … “the technical department within the NZ Transport Agency have not found that your specific complaints justify further enquiry as they are satisfied that vehicle does not currently present a risk to land transport safety.”

Cassidy soon fired back, saying Robson had “jumped to conclusions without ascertaining the facts.” He said he had a contract with the ACC to inspect the ‘engineering’ issues of the vehicles in production, “as a professional engineer, not as a certifier.”

Cassidy further told Robson that ACC executive Gail Kettle had asked him early in August, 2008, if he would like to see one of the Italian-modified Kias. Robson later replied, saying “it is not my intent to enter into a debate over the issue.”

ACC THOUGHT ITALIAN VEHICLE WAS ‘BEE’S KNEES’ …

Cassidy had had many dealings with Kettle, then the ACC purchasing executive for health and provider relationships. Cassidy had previously inspected vehicles modified for the ACC by Waikato firm Vehicle Adaption Services (VAS). Kettle cancelled the ACC agreement with VAS after a recall over a reported seatbelt malfunction and chose Italian firm KIVI as the preferred new supplier. Kettle is now the Earthquake Commission’s general manager customer and claims.

The vehicle Kettle arranged for Cassidy to see was trucked from Wellington to Tauranga, where it was met by an ACC occupational therapist. “Gail Kettle wanted me to check it out because she thought it was the bee’s knees,” Cassidy said. It was late in the evening when he met the therapist at an ACC’s client house. “The therapist asked me about towbars, seatbelts and the vehicle in general. Only a brief inspection by torchlight was possible. I asked if I could inspect it properly in the morning light but she said she had to drive it to Auckland that night.”

What Cassidy had seen in a few minutes concerned him, he said. “For a start the heavily modified rear end wasn’t strong enough to accommodate a towbar.” He said he met with Kettle weeks later on another matter. “I hinted that I wasn’t happy with what I had seen with the Italian vehicles. She was in a hurry to get to a meeting and that was the last conversation I had with her,” said Cassidy.

IDENTICAL VEHICLE HAD ‘REMEDIAL’ WORK DONE ON IT …

Over the next few weeks Cassidy arranged to inspect an identical vehicle in use by a family in Te Awamutu. He said the family told him the vehicle had just had ‘remedial’ work done on it in Wellington. On November 6, 2008, Cassidy checked out the Italian-modified van at the VAS workshop, in Matangi, near Cambridge.

With him, he said, were NZTA reviewer Bruce Adams (confirmed later by Robson’s letter to Cassidy) and LVVTA certifier Neal Miller. Days later Cassidy sent his report to the ACC’s Payne. He said that whatever ‘remedial’ work had been done on the vehicle in Wellington, the faults he identified were still present. His was the only signature on the letter.

In December, 2012, the NZTA’s sidekick the LVVTA issued a recall on its website – www.ivvta.org.nz – for the long-wheelbase vans to repair “fracturing to trailing arms” in the rear suspension. The recall mentioned “incorrect suspension geometry and poor workmanship involved in the modification process.” The LVVTA said Braiden International would do the repairs. The repairs weren’t completed until late 2013, early 2014, said Braiden’s Rochelle Williams.

The “fracturing” the LVVTA said needed fixing was exactly what Cassidy had said would happen back in 2008. He identified “incorrect suspension geometry” and “poor workmanship” back then too. Cassidy is one of the NZTA’s most reputable professional engineers. Why wasn’t his 2008 warning to the NZTA and ACC acted on? Why wasn’t it passed to the LVVTA, which is indirectly responsible for certifying wheelchair-access vehicles.

NZTA CERTIFIER’S TIME FRAME WAS ‘VERY LIMITED’ …

LVVTA chief Tony Johnson said he never received a copy of Cassidy’s 2008 letter. “Had we been made aware of the issues identified by Mr Cassidy we certainly would have become involved earlier,” he said.

Johnson said the LVVTA didn’t certify the vehicles. “Nor do we certify any vehicles. Modified vehicles are inspected and approved by independent LVV certifiers who are appointed by the NZTA. LVVTA’s role is to provide technical support and training to the LVV certifiers.”

He said he understood the certifier’s time frame to inspect the vehicles was “very limited.” “I also believe he would have based some of his decisions that the vehicles were sound after reviewing the vehicles’ European type-approval certification, which was presented to the ACC team at the time of inspection,” Johnson said.

Johnson said he agreed that there were problems with the vehicles’ design and construction. “But in balance they would have been very difficult for (the certifier) to identify in isolation. It’s easier to identify problems with the luxury of several heads, and several hours, particularly when someone is bringing problems to your attention.”

But engineer Cassidy identified on his own, in a few minutes, in a Tauranga driveway, in the dark, with a torch, that the modified vehicles for which the ACC had paid $8.34 million didn’t stack up.

Weeks later, with the NZTA’s Adams and LVV certifier Miller in tow, Cassidy inspected an identical example, this time for three or four hours, in a garage workshop, on and off a hoist. Days later, the NZTA rejected Cassidy’s report that the vehicles were badly flawed. Since then the NZ taxpayer has had to fork out hundreds of thousands of dollars to fix what the NZTA said in 2008 wasn’t a problem.

MY COMMENT ON THIS
All modified vehicles entering the NZ Fleet need to be LVV Certified, according to the Vehicle Standards Compliance Rule 2002, Clause 6.5(1)(c)

Clause 3.2 Action following failure to comply with conditions of appointment or with this rule
3.2(1) If the Director has reason to believe that a vehicle inspector or inspecting organisation has failed to comply with any of the conditions of their appointment, or has failed to comply with this rule, the Director may require the inspector or organisation to undergo such an investigation and to provide such information as the Director reasonably considers appropriate.

3.2(2) Subject to 3.2(3), if, following an investigation under 3.2(1), the Director is satisfied that a vehicle inspector or inspecting organisation has failed to comply with any of the conditions of their appointment, or failed to comply with this rule, the Director may do one or more of the following:

(a) require that remedial action, such as training, be undertaken by the inspector or organisation;
(b) suspend the whole or any part of the appointment of the inspector or organisation for a specified period or until specified conditions are met;
(c) revoke the whole or any part of the appointment of the inspector or organisation.

THE LOW VOLUME VEHICLE SYSTEM HAS LOST THE ABILITY TO CARRY OUT HIGHER LEVEL CERTIFICATIONS SUCH AS THESE, BECAUSE

A ….. LVV STANDARDS COVER ONLY VERY BASIC MODIFICATIONS.
B ….. THE SKILLED AND QUALIFIED CERTIFIERS HAVE LEFT THE SYSTEM, REPLACED BY ‘HOBBYIST’ CERTIFIERS.

The LVV system is reverting to just a low-level ‘hobby car’ certification system.

We intend to make an official Information Request to NZTA as to how these vehicles were permitted to enter the NZ Fleet, what Technical Evaluation was carried out, and what remedial action the Director will be taking.

QUESTIONABLE OPERATION OF THE LVVTA

Here are two examples of the sort of questions that do need to be asked and answered before a way forward for the LVV System can be found:

QUESTION 1 How can the NZ Transport agency justify allowing the LVVTA to make Certification judgements?
The LVVTA have a contract for ‘Desktop Auditing’ to ensure LVV Certifiers are meeting the LVV Standards, however the LVVTA appear to be making Certification decisions under this guise.
We can see no provision in any legislation authorizing NZTA to allow this.

QUESTION 2 On what basis does the LVVTA assume that their knowledge is superior to that of the LVV Certifiers? None of the LVVTA Staff are LVV Certifiers, and do not even meet the requirements for many categories. Yet experienced LVV Certifiers have their judgement questioned, are required to accept the judgement of the LVVTA, and are reported to NZTA for ‘incorrect’ decisions. Several recent incidents have proven that the judgement of the LVVTA can be seriously wrong.

CONSEQUENCES
The LVV system is failing to retain the skilled Certifiers
on which integrity and safety of the system depends- such as-

( Names removed by request )

LVVTA are now slanderering these ex-Certifiers, calling them ‘Rogue Certifiers’ and ‘safety risks’ instead of recognizing them as outstanding, highly regarded Certifiers whose experience is a major loss to the system.

THE LOW VOLUME VEHICLE SYSTEM HAS LOST THE ABILITY TO CARRY OUT HIGHER LEVEL CERTIFICATIONS, BECAUSE

A ….. LVV STANDARDS COVER ONLY VERY BASIC MODIFICATIONS.
B ….. THE SKILLED AND QUALIFIED CERTIFIERS HAVE LEFT THE SYSTEM, REPLACED BY ‘HOBBYIST’ CERTIFIERS.

The LVV system is reverting to just a low-level ‘hobby car’ certification system.

Emergency appointments of Certifiers from a ‘Hot-Rod’ background lacks credibility, because:-
1…..’hot rod’ experience in no way qualifies a LVV Certifier to deal with the range and complexities of modern automotive engineering.
2…..a Certifier who is beholden to the LVVTA lacks the independence required by the deed of appointment.

The LVV system is failing to meet the needs of vehicle modifiers– the number of Certifications is falling whilst the number of vehicles and the number of mods needing LVV Certification are rising-

1…….Abandoned Certifications We receive continuous enquiries for LVV Certification, from all over New Zealand.
We give out the phone numbers of other Certifiers, we even contact them ourselves on behalf of customers.
In the end, we are left with sheaves of job-sheets, for vehicles which WILL NEVER BE LVV CERTIFIED

2……Modified cars exported- We are aware of many modified and scratch-built vehicles EXPORTED to avoid the LVV system in NZ

3……Modifiers leaving the business- We are aware of PROFESSIONAL MODIFIERS (many with export business) who have CLOSED THEIR BUSINESSES or moved out of NZ.

U Drive Mobility are one recent example of this- now building in France

4…..Avoidance of LVV System Motor-home builders IN NEW ZEALAND switching to Certification to ADR Second Stage system, to avoid the costs, delays, and irregularities of the New Zealand LVV system. Private modifiers are being forced to drive vehicles without LVV Certification

Uncertified vehicles

Police at the bottom of the cliff (Ambulances not visible in this shot)

5……Soaring costs-
The LVVTA levy, has increased, with more increases anticipated, as legal and insurance costs start to bite.
LVV Certifiers have increased their charges to cover time they now require to process Certifications.
In Auckland the total cost to the customer for LVV Certification has increased by an average of 25% in June 2014.

This means that to LVV Certify say, a set of wheel spacers, or adjustable platform suspension struts, will now cost the vehicle owner $550 to $650, which could exceed the cost of the modification.

If NZTA loses faith in the LVV System, (Quite likely)
it is possible that:

1 … Minor Modifications: TSD agents, or WOF agents be authorized to pass a range of minor modifications

2 … Self- Certification: Professional Modification businesses (seat installers, motor-home builders etc) be accredited to Self-Certify

3 ….Hobby cars and Hot-rods– (a very small part of the LVV picture) could be left out in the cold, are unable to be driven on the road.

Not road legal

Going to the Beach Hop?

4 …. The LVVTA and LVV Certification plates become history.

IS THIS THE FUTURE WE WANT?

How about some clear thinking about the LVV System of the future?

1 Trust the Certifiers to do the job they are appointed to do. Cut LVVTA out of the Certification process. Allow Certifiers to make their own plates, or use a Certifier appointed Plate printing contractor.

2 Introduce proper “Certifier Training”, conducted ‘on line’ and on the job, by Certifiers or Industry Professionals, (not by the LVVTA) and allow proper technical debate to occur.

3 Allow Certifiers to Certify to proven International Standards if they choose, instead of faulty LVVTA Standards.

4 Form a Certifier controlled “Standards Committee” to develop and change LVV Standards, instructing LVVTA to print and distribute.

5 Simplify Certifier Categories to say “Mechanic based Certifier” (able to do most certifications) and “Engineer Certifier” for situations where the skills of an Engineer are required. Allow “Engineer Certifiers” to consult to “Mechanic Certifiers” when required.

Aftermarket seats – the seatbelt buckle problem

Mnay enthusiasts want to fit aftermarket seats to their cars.
A problem arises when the original seat has the seatbelt buckle mounted on the seat, so that the seatbelt load goes through the slide rails to the car.
The easiest option is to keep the original slides, and mount the new seat to them. This way the seatbelt anchorage is unchanged.

If this is not possible, and the aftermarket seat has its own base and slide rails, this is where the problem arises.
There needs to be TEST DATA to show that the aftermarket rails are strong enough for the seatbelt load- and THERE NEVER IS ANY TEST DATA

There are two ways around this:
1 Fit a new Seatbelt Anchorage to the vehicle tunnel. This is done using standard Seatbelt Anchorage doubler plates of at least 3000 sq mm area (such as 80 x 50, or 100 x 40).
2 Bracketing the seatbelt buckle to the seat anchorage, using a piece of 40mm x 3 mm flat bar, usually about 100 to 150mm long, drilled for the 7/16 seatbelt bolt at one end, and drilled to fit the seat mounting bolt (usually M10) at the other.

It is a requirement that the Seatbelt is mounted with a 7/16 or M12 bolt. There are good reasons for this, and the seatbelt hardware is all made for this size of bolt.

The seat mounting bolt is whatever the vehicle manufacturer deemed appropriate- a M10 grade 8.8 bolt can take a shear load of 48 Kn, which is more than meets the load requirement for a seat and the seatbelt buckle loading.

The Manufacturers underfloor mounting plate for the seat is designed to take this load- the picture below shows that the seatbelt load in a standard seat is transmitted just to this one bolt- proving that this is true.
So we can rely on the Original, Factory seat mounting point, and the Original seat mounting bolt to take the seatbelt loads, the load just gets there by the new bar we have added.
NOTE- Remember to put the seatbelt load bar between the seat and the tunnel or floor.
