Hi Shaun, When you say historically, that would imply there are General aviation aircraft flying in New Zealand with the same repair? regards Al Gray Westland air charter

Hi Al
Regardless of the fact that CAA has historically approved a weld process, the fact remains that the Engine design and manufacturing authority have made it very clear that welding is not permitted in this area of the crankcase without specific authorisation; as reflected in the approved maintenance procedures.
Notwithstanding the above, I am happy to discuss this issue with Don or Aviation Power Supply staff as required.

Subject: crankcase weld repair ZK-CBT
Dear Mr Johnson
I have asked the various companies involved in this weld repaired crankcase and have discovered that their process has been approved by CAA .
And their would be a large number of similar aircraft in New Zealand on part 135 ops that you would now need to ground based on this repair that has been performed on these aircraft engines by Oceania aviation and its contracted companies.
I have forwarded your letter of suspension to Mr Don McCracken regarding this engine .

Dear OIA,Further to this request is a question that raises the legality of such welds.If CAA are allowing welded crankcases in New Zealand aircraft to continue flying , when are we going to see this approval revoked or endorsed by CAA.?
Furthermore ,How would CAA capture an imported aircraft that has been crankcase welded offshore ?
Yours sincerely,

Dear Mr Gray,
Official Information Act 1982 (the Act) Request
As discussed during the Mar 20 meeting with Mr Johnson, with the exception
of the engine issues associated with ZK-CBT, all other known crankcase
welds are supported by approved technical data. As such, no further
Airworthiness action is required. As also discussed, existing welds in
crankcase assemblies fitted to imported aircraft will be supported by
approved technical data contained within associated technical /
maintenance records; which the CAA reviews as a component of the initial
Airworthiness certification review.
Thanks,

Dear OIA,
Since CAA have singled out one aircraft engine that has been crack welded by a CAA approved workshop, can we expect there have been other aircraft engines welded in the same manner.The fact that CAA state , there was no technical data is false and misleading.If there is no TECHNICAL DATA to supauthorised by the port this weld repair, then CAA should either revoke Oceanias approval or look back historically for all the other welding that was performed by Oceania and its subsidiaries.
There seems to be a double standard here. Most Aviation authorities would take exception to a company performing welding they didnt approve of, but they dont seem to mind in this case.
Ask yourself a certain question, would you still allow a company to perform welds that are not authorised by the manufacturer?
CAA are.
Yours sincerely,
Westland air charter ltd
