Airworthiness Directive 95-26-16

What this AD requires
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 95-26-16 R1, which was sent previously to all known U.S. owners and operators of certain Mooney Aircraft Corporation (Mooney) Model M20J airplanes. This AD requires repetitively inspecting the alternate air door assembly to ensure a cotter pin exists and is secure, and replacing the cotter pin if it does not exist or is not secure. It also provides the option of incorporating an alternate air door plate assembly of improved design as terminating action for the repetitive inspections. Priority letter AD 95-26-16 R1 was prompted by a fatal accident involving one of the affected airplanes where the alternate air door became lodged in the air intake of the fuel injector causing engine failure. The actions specified by this AD are intended to prevent the alternate air door from separating from the airplane and restricting air flow to the engine.
Which aircraft AD 95-26-16 applies to
Model family M20 inferred from the referenced Mooney Service Bulletins (M20-250B / M20-253A); exact model/serial applicability not stated in extracted text. Requires inspection of the alternate air door assembly cotter pin and, if missing/insecure, replacement or modification (plate P/N 600355-507, rivets MS20426AD3, cotter pin MS24665-132, nut MS17825-4, washer AN960-416) per Mooney SB M20-250B or M20-253A (December 1995), superseding SB M20-250A/M20-253 (May 10, 1992).
Whether AD 95-26-16 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
