Airworthiness Directive 2008-10-01
one-timeAirworthiness Directives; Eurocopter France Model EC120B Helicopters
What this AD requires
We are adopting a new airworthiness directive (AD) for Eurocopter France Model EC120B helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on a helicopter. The aviation authority of France, with which we have a bilateral agreement, states in the MCAI:
Which aircraft AD 2008-10-01 applies to
Applies only to helicopters with a spherical thrust bearing, P/N 7050A3622036, bearing serial number LK0130, LK0142, LK0155, or LK0158, installed. These bearings are from a batch found unfit for flight; failure in flight could cause the main rotor system to separate from the helicopter.
Whether AD 2008-10-01 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.
