Releasing an aircraft prior to repair scheme finally approved RDAS

[Neil Armstrong]

I have a question.... following on from the recently released UK CAA Skywise statement see this link: http://skywise.caa.co.uk/repairs-app...sations/?cat=7 it is clear to me that until the final approved documentation from the Part 21 that issued the repair instructions has been received we should not be releasing the aircraft back to service, simple and obvious when you think about it, however consider this scenario.. lets say as an example Airbus has issued repair instructions to an EASA Operator to repair damage that was outside of SRM limits but has yet to issue the final paperwork, the fully signed RDAS in the case of Airbus, however the Operator's own Part 21 issues a DOI to permit continued operation, with restrictions ie time or flt cycle limits, following completion of the repair without deviation, until Airbus completes the RDAS, can you release the aircraft based on this DOI? I think not on the grounds that the Operators Part 21 did not produce the repair (assume it was outside of their scope) and therefore does not have the ability to allow temporary fly on because of it not being the Part 21 that issued the repair.

What are your thoughts guys?

Thanks for any advice in advance.

Answered your own question mate. Unless the OEM PART 21 say it is good to go, the uni chap in your company can wind his neck in, it is not his shout.

Thanks Alber, I agree! It's scary how many Certifyers don't get this subject generally though, after all that's the reason the CAA had to publish the advice, cheers.

Agree with AR. You "MUST NOT" certify a repair etc unless the Part 21 Cert is with you (or RDAS etc).....!!!!!

Has to be a spineless bootlicker to get involved in that way, even if the beancounters were on his case.
