The RAAus aircraft condition report has several important things that I think PROTECT the L2:
I just looked up the form on their website - I'm not an RAAus member.
The Level 2 / 4 inspector (or LAME) does not assume responsibility for the airworthiness or otherwise of
this aircraft. Airworthiness of the aircraft rests solely with the owner.
It's not the L2's airplane - indeed they may have never seen it before, or will ever again.
In the checklist there are PASS or FAIL columns. And then a sign-off:
This certification does not infer that I consider the aircraft to be airworthy or otherwise.
It is a condition report, not a "this aircraft is 100% airworthy and will remain so forever" report. Nor is it any sort of repairs required order. It's a report by an independent experienced person that RAAus has appointed, describing what they see. Once their inspection is complete - their job for this task is done. What happens after that - not their responsibility, it's still not their airplane! A wise buyer or seller will evaluate any fails noted and hopefully address them.
It seems to me to be a good program to require this independent condition report at time of sale and it's a good way for RAAus to track over time, changes made to the aircraft.
