flight permit required to overfly 100hr inspection?

Asked by: 4534 views FAA Regulations

If I'm going to a destination where the 100hr inspection can be done, do I need to get a flight permit to overfly up to 10hrs or is it okay?

    No. There’s nothing unairworthy about the airplane =solely= because it overflies the FAR 91.409(b) 100 inspection.

    But that said, your question had me scratching my head. Not enough information to know whether either the 100 inspection rule or the 10 hour grace period actually applies.

    100 inspections are required for only two operations: (1) flight instruction where the aircraft is provided by the instructor; (2) aircraft carrying paying passengers (passengers for compensation or hire). So, unless that flight to get the inspection done is being done during an instructional flight or with a paying passenger on board, the 100 hour rule doesn’t even apply. No grace period to worry about.

    The grace period is for unintentional rule violations. Do a planned 2 hour instructional flight with 2.5 left before the inspection is due and encounter an unexpected delay, and you are in the grace period. Do that same flight with 1.5 left and you do not have grace period protection.

    In 2014, the Chief Counsel gave its interpretation of a number of 100 hour scenarios that help explain some of the intricacies of the rule. https://www.faa.gov/about/office_org/headquarters_offices/agc/pol_adjudication/agc200/interpretations/data/interps/2014/Greenwood-Fly%20By%20Knight%20-%20(2014)%20Legal%20Interpretation.pdf

    BTW, practically speaking, for a lot of light aircraft, overflight is not simply a 100 rule problem. Many have repetitive ADs that coincide with 100 inspection timing. Overflying an AD has no grace period and would require that ferry permit.
