Airworthiness Directive 2000-08-05
recurringAirworthiness Directives; Agusta Model A109C and A109K2 Helicopters
What this AD requires
This amendment supersedes an existing airworthiness directive (AD), applicable to Agusta Model A109C and A109K2 helicopters, that currently requires removing the main rotor pitch control link assemblies, measuring the radial play of each upper and lower spherical rod-end bearing (bearing), and replacing any unairworthy bearing. This amendment requires replacing the pitch control link assembly with an assembly that has increased durability and wear resistance. This amendment is prompted by reports of increased helicopter vibration caused by wear of bearings on certain pitch control link assemblies. The actions specified by this AD are intended to eliminate the need for recurring bearing inspections and to prevent failure of a bearing, increased helicopter vibration, and subsequent reduced controllability of the helicopter.
Which aircraft AD 2000-08-05 applies to
Rework and reidentify main rotor pitch control link assembly P/N 109-0110-71-103 or -105 to P/N 109-0110-71-107 per Agusta Bollettino Tecnico 109K-10 or 109-103, both dated Nov 22, 1995; related to RAI (Italy) ADs 95-332 and 95-334.
Whether AD 2000-08-05 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.
