Airworthiness Directive 2002-25-01
one-timeAirworthiness Directives; Eurocopter France Model AS332C, AS332L, AS332L1, SA330F, SA330G, and SA330J Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters that requires inspecting the tail rotor pitch change rod (change rod) bearing (bearing) and, after inspecting the control rod, replacing the bearing if it does not meet the specified tolerance. This AD requires inspecting the bearing for spalling, friction, and grinding and inspecting the control rod and bearing housing for wear marks and scoring. This amendment is prompted by the seizure of a bearing on an ECF Model SA330 helicopter. The actions specified by this AD are intended to prevent bearing wear, seizure of the bearing, loss of tail rotor effectiveness, and subsequent loss of control of the helicopter.
Which aircraft AD 2002-25-01 applies to
Recurring inspection (within 20 hrs TIS/1 month, then every 250 hrs TIS/18 months, or before installing a tail rotor gearbox not inspected within the prior 250 hrs TIS) of tail rotor pitch change spider assembly bearing axial end play and condition, per Eurocopter France ASB 05.81 Rev 2 (Model 330) or ASB 05.00.29 Rev 3 (Model 332); remove unairworthy bearings, change rods, or bearing housings from service.
Whether AD 2002-25-01 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.
