Applicability*9
This AD applies to Airbus Helicopters Model EC225LP helicopters, certificated in any category, all manufacturer serial numbers.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2020-0079, dated April 1, 2020 (EASA AD 2020-0079).
Unsafe condition
This AD was prompted by a report of a manufacturing and control issue regarding the ceramic balls in the bearing installed in the swashplate assembly of the main rotor mast assembly. The FAA is issuing this AD to address defective ceramic balls in the bearing installed in the swashplate assembly of the main rotor mast assembly, which could lead to premature spalling of the ball itself and of the bearing, loss of function of the bearing, and overload of the main rotor mast scissor, resulting in reduced control of the helicopter.
Affected ADs
None.
