Applicability*9
This AD applies to Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2023-0194R1, dated March 19, 2025 (EASA AD 2023-0194R1). Note 1 to paragraph (g): EASA AD 2023-0194R1 and Airbus Helicopters material that is referenced in EASA AD 2023-0194R1 refer to MGB suspension bar attachment “bolts” as “screws.” Note 2 to paragraph (g): Table No. 1 of Airbus Helicopters Alert Service Bulletin No. AS332-53.02.13, Revision 1, dated April 5, 2024, identifies the helicopter group configurations referenced in EASA AD 2023-0194R1.
Unsafe condition
This AD was prompted by tests and analyses performed by the manufacturer. The FAA is issuing this AD to prevent fatigue failure of the main gearbox (MGB) suspension bar attachment fittings and bolts by remaining in service beyond their fatigue life. The unsafe condition, if not addressed, could result in failure of an MGB attachment assembly, detachment of an MGB suspension bar, and consequent loss of control of the helicopter.
Affected ADs
This AD replaces AD 2020-06-13, Amendment 39-19882 (85 FR 19080, April 6, 2020).
