Sikorsky S-92A

The FAA is superseding Airworthiness Directive (AD) 2022-02-01 for Sikorsky Aircraft Corporation Model S-92A helicopters with certain part-numbered main rotor stationary swashplate assemblies (swashplate assemblies) that had accumulated 1,600 or more total hours time-in- service (TIS) installed. AD 2022-02-01 required visually inspecting the swashplate assembly at specified intervals and depending on the results, removing the swashplate assembly from service. Since the FAA issued AD 2022-02-01, the FAA determined it was necessary to expand the applicability and require more detailed inspections to address the unsafe condition. This AD retains the actions of AD 2022-02-01, expands the applicability, adds a detailed recurring visual inspection, and requires either eddy current inspections (ECI) or fluorescent penetrant inspections (FPI). The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2020-26- 13, which applied to certain Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. AD 2020-26-13 required establishing the life limit for certain part-numbered horizontal stabilizer root fittings FWD (forward root fittings) and certain part-numbered stabilizer strut fittings. AD 2020-26-13 also required repetitively inspecting certain parts, and depending on the inspection results, removing parts from service. Finally AD 2020-26-13 prohibited installing certain stabilizer assemblies on any helicopter. Since the FAA issued AD 2020-26-13, the manufacturer notified the FAA that due to an error in the service information, certain part numbers in AD 2020-26-13 are incorrect. Also, the FAA determined that additional inspections are required to address the unsafe condition. This AD retains certain requirements and the prohibition for installing certain stabilizer assemblies on any helicopter from AD 2020-26-13, corrects certain part numbers, and requires additional repetitive inspections. The actions of this AD are intended to address an unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation Model S-92A helicopters. This AD was prompted by a cracked main rotor stationary swashplate assembly (swashplate assembly). This AD requires visually inspecting the swashplate assembly at specified intervals and depending on the results, removing the swashplate assembly from service. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This AD was prompted by an incident of a side facing utility seat detaching from wall attachment points. This AD requires modifying certain side facing utility seats and observer seats, and prohibits installing those seats unless the modification has been accomplished. The FAA is issuing this AD to address the unsafe condition on these products.
