Conformity Inspection

 So, I did a conformity inspection to put an airplane on a 135 certificate. Our FAA inspector would not sign off on it until he saw a statement in the logbook stating that the aircraft met conformity. He quoted 14 CFR 43.11. I talked with other mechanics and directors of maintence and they had never heard of entering a conformity into the logbook. Is our inspector full of it? I have never seen an entry like this in a log book before. I did it anyway rather than argue with him because we needed the plane.

My experience would be, it depends upon the inspector but it is helpful once an aircraft has been added to a 135 Certificate if the aircraft has its own AAIP program. Something along the lines of 'Date: xxx, Aircraft: N1234, Aircraft Serial Number: xxx Aircraft Hours: xxx added to 135 Operations Specifications on Ops Certificate DEA110XT for charter use. The aircraft is maintained under (insert the maintenance program you will be utilizing for compliance, this must match the way you have told the FAA you are going to maintain it - if it is by AAIP then the AAIP needs to be approved but if its manufacturer recommended then the OEM recommended program.'

Is it required? I think your PMI would be hard pressed to prove it but it is easy enough to do and if it makes him happpy hell let him look for something else. Also if the airplane is sold or removed form the 135 Ops Specs then you will need to make another entry that reads 'Date: xxx, Aicraft: N1234, Aircraft Serial Number: xxx Aircraft Hours: xxx - Aircraft removed from 135 Ops Specs and is no longer operated under 135 Ops Certificate: DEA110XT'

Hope that helps.

As a former FAA inspector (retired) I would say your inspector may be full of it and does not fully understand the word inspection. In my book, titled “Hand Book of Aeronautical Inspections and Pre-Purchases” I explained the approved inspections that the FAA recognizes and a conformity inspection is not one.

When an annual, AAIP, or progressive inspection is completed the mechanic has in essence has completed a conformity inspection insuring the aircraft meets it type design. Nowhere in the CFR’s does it call out a required conformity inspection. It does call this out in FAA Order 8900.1 for inspectors when adding an aircraft to a part 135 certificate. The operator is responsible for insuring the aircraft meets type design and or properly altered condition by doing a conformity making sure what is installed is what the paper says it is.

In order for an aircraft to be used in air taxi the aircraft must undergo a conformity inspection to assure the aircraft conforms to its original type design or properly altered condition, meets all additional operational regulations applicable for intended use. And is in condition for safe flight

Conformity inspections involve the review of all design data and production documents generated as part of a design approval program with the Federal Aviation Administration (FAA). In recent years, the FAA has been moving in the direction of becoming an agency whose function is that of oversight.

I think the inspector may have set the operator up for failure by requiring a maintenance record entry indication the aircraft has had a conformity inspection. If it were me I might of signed the aircraft records off indicating a records inspection and determined the aircraft meets it type design and is in a safe condition for flight and is considered airworthy at this time (reference the airworthiness certificate).

In addition, I would go back to the inspector and request in writing something that required the mechanic to make a record entry for the conformity inspection that the FAA inspector requested and was accomplished (CYA).

Just one man’s opinion.

The conformity inspection is not a required maintenance inspection, and doesn't fall under the record entry requirements of 43.11. In the performance of that inspection, if maintenance actions were done (remove and install inspection panes for instance) that would require a 43.9 maintenance record entry. I would make an entry, but would be very carefull on how the entry was recorded. Say what you did, and do what you say.
