Airworthiness Directive · Amendment 39-15507 · Main rotor hub
Eurocopter France Model EC120B Helicopters
Superseded. A later AD replaced this one: AD 2025-05-12. Comply with the one in force.
This AD applies to Model EC120B helicopters, with spherical thrust bearings, part number 7050A3622036, serial number LK0130, LK0142, LK0155, and LK0158, installed, certificated in any category.
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:
Before further flight, remove any spherical thrust bearing, part number 7050A3622036, serial numbers LK0130, LK0142, LK0155, or LK0158, and replace it with an airworthy spherical thrust bearing.
None.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
