Airworthiness Directive 2000-01-10
one-timeAirworthiness Directives; Pilatus Aircraft Ltd. Model PC-7 Airplanes
What this AD requires
This amendment supersedes Airworthiness Directive (AD) 98-08- 07, which currently requires replacing the rudder and elevator pivot arms with parts of improved design on certain Pilatus Aircraft Ltd. (Pilatus) Model PC-7 airplanes. This AD requires replacing the rudder and elevator pivot arms with parts that have been improved since issuance of AD 98-08-07. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to prevent failure of the elevator and rudder caused by fatigue cracking of the pivot arms, which could result in reduced airplane controllability and possible loss of control of the airplane.
Which aircraft AD 2000-01-10 applies to
Replace elevator and rudder trim tab pivot arms with improved-design parts per Pilatus Service Bulletin No. 55-003, dated July 7, 1999; supersedes AD 98-08-07, whose prior alternative methods of compliance are not automatically approved for this AD.
Whether AD 2000-01-10 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.
