Airworthiness Directive 2010-15295
one-timeAirworthiness Directives; Ontic Engineering and Manufacturing, Inc. Propeller Governors, Part Numbers C210776, T210761, D210760, and J210761
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain serial numbers (S/Ns) of Ontic Engineering and Manufacturing, Inc. propeller governors, part numbers (P/Ns) C210776, T210761, D210760, and J210761. This AD requires removal of the affected propeller governors from service. This AD results from three reports received of failed propeller governors. We are issuing this AD to prevent loss of propeller pitch control, damage to the propeller governor, and internal damage to the engine, which could prevent continued safe flight or safe landing.
Which aircraft AD 2010-15295 applies to
Propeller governors applicable by serial number, as listed on pages 3 and 4 of Ontic Mandatory Service Bulletin No. SB-DES-353, Revision A, dated December 16, 2009. Installed on, but not limited to, American Champion Aircraft Corporation Model 7GCAA (governor P/N T210761), Diamond Aircraft Industries, Inc. Model DA-40 (governor P/N C210776), Hawker Beechcraft Model A36 (governor P/N D210760), and Industria Aeronautica Neiva S/A (subsidiary of Embraer) Model EMB-202A (governor P/N J210761) airplanes.
Whether AD 2010-15295 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.
