Airworthiness Directive 2009-06-14
one-timeAirworthiness Directives; Fokker Model F.27 Mark 050 Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.27 Mark 050 airplanes. This AD requires measuring the length of the extended portion of the sliding member of the main landing gear, performing an inspection for the presence of lockwiring, and doing corrective actions if necessary. This AD results from a report that the sliding member of the main landing gear has been overextended after landing. We are issuing this AD to detect and correct improper installation of the lockwire on the two lockbolts that hold the sliding member end stop, which could result in structural damage of the main gear and loss of control of the airplane during the landing roll, due to main landing gear overextension.
Which aircraft AD 2009-06-14 applies to
Whether AD 2009-06-14 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.
