Airworthiness Directive 2013-22-23
one-timeAirworthiness Directives; AERMACCHI S.p.A. Airplanes
What this AD requires
We are rescinding Airworthiness Directive (AD) 2013-22-23 for AERMACCHI S.p.A. Models F.260, F.260B, F.260C, F.260D, F.260E, F.260F, S.208, and S.208A airplanes equipped with a Lycoming O-540, IO-540, or AEIO-540 (depending on the airplane model) wide cylinder flange engine with a front crankcase mounted propeller governor. AD 2013-22-23 resulted from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. We issued the AD to detect and correct improper position of the set screw, which could lead to complete loss of engine oil pressure and result in emergency landing. Since we issued AD 2013-22-23, we have determined the unsafe condition does not exist specific to the airplane design features.
Which aircraft AD 2013-22-23 applies to
F.260/F.260B/F.260C/F.260D/F.260E/F.260F models apply only when equipped with a Lycoming O-540, IO-540, or AEIO-540 wide cylinder flange engine (serial number suffix 'A' or 'E') with a front crankcase mounted propeller governor. S.208/S.208A models apply only when equipped with a Lycoming O-540 wide cylinder flange engine (serial number suffix 'A' or 'E') with a front crankcase mounted propeller governor.
Whether AD 2013-22-23 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.
