I personally believe there are some fundamental problems with how aircraft owner responsibility is currently addressed and trained in General Aviation.
The Federal Regulations (CFR Title 14, FAR 3.5) defines airworthiness as (I paraphrase):
1 - must be in the approved configuration and
2 - must be maintained in a safe condition.
(This excludes the experimentals.)
In a airline (granted more demanding rules, more demanding operation) there are usually at least three departments devoted to aircraft operations.
1 -an engineering department that controls aircraft configuration and configuration changes, configuration management records, and maintains manuals and drawings to support continuous airworthiness and safe operation of modified aircraft.
2 - A Maintenance department that maintains the aircraft in a safe condition, accomplishes the mods developed or approved by the engineering department and maintains aircraft maintenance records.
3 - Of course the 3rd group is the Operations group containing the pilots working through all the rules for operations.
The airline model is probably not the only way to do it, but generally that's what I see now. It's probably a reflection of operator cert requirements. I can't speak for Military.
In General Aviation, you have the pilots, pilot/owners, mechanics and mechanic/inspectors doing everything. Now everyone in GA understands the oil changes, compression checks, and annual/100 hour inspection requirements.
The big problem I see is that most pilot owners and mechanics really don’t get much training on aircraft configuration management. Those are the topics related to TC, STCs, PMA, 337 & Major/Minor Alteration processes, Field Approvals and to some degree PMA etc.
Given that the very first requirement for airworthiness is “approved configuration,” technically, even if the mods are done properly (I said if), if you don't have the records, no one has any way to even know if plane is airworthy (much less maintained in a safe condition).
If you see controls in the airplane that aren't in the approved pilot hand book, and no records in the log book, you have no idea what you have.
If you find devices installed on the airplane with no paperwork documenting the changes to the electrical loads, no wiring diagrams, no STC, you really don't know what you have. And you really have no way to maintain or operate it until you do. Are the emergency checklists still valid? Who knows?
If you have equipment installed by an STC and there is no authorization to use letter for that STC, it’s also violation of both the FARs and public law.
I personally feel when you by an airplane, the paper airplane is very important if you expect to operate your airplane safety, expect it to be maintainable, expect it to have resale value. A lot of that responsibility falls on the owner, just like it’s the owner’s responsibility to make sure maintenance records are properly maintained.
On those matters, what I see and hear in GA looks more to me like a cargo cult. I think it's worse with very old airplanes with numerous modifications necessitated by obsolescence and fairly complex new requirements.
Many A&P/IAs never own an airplane and have no idea how or why some of the paperwork is even developed. I’m not sure I believe some of the folks at FAA do either. Maybe my perception will change as I enter my 3rd and 4th year of ownership, but right now, that’s how I see it. Just my 2 cents.
