What to do
Operators of affected Sikorsky S-92A helicopters must perform a visual inspection of the swashplate assembly within 50 hours time-in-service after February 18, 2022, and continue inspections at intervals not exceeding 50 hours. If any cracks, nicks, dents, or scratches are found beyond allowable limits, the swashplate assembly must be removed from service immediately. Operators should refer to Sikorsky Alert Service Bulletin ASB 92-62-009 for inspection guidance and maintain records of compliance.
Summary
FAA Airworthiness Directive 2022-02-01 is a final rule addressing certain Sikorsky Aircraft Corporation Model S-92A helicopters equipped with main rotor stationary swashplate assemblies part numbers 92104-15011-042 or 92104-15011-043 that have accumulated 1,600 or more total hours time-in-service. This directive requires repetitive visual inspections of the swashplate assembly to detect cracks, nicks, dents, or scratches to prevent potential failure. The AD was issued due to the discovery of cracks that could lead to loss of control of the helicopter.
What changed
This new airworthiness directive introduces mandatory repetitive visual inspections of the swashplate assembly at intervals not exceeding 50 hours time-in-service. If any cracks or damage exceeding allowable limits are found, the swashplate assembly must be removed from service before further flight. The AD is considered an interim action pending further rulemaking based on forthcoming service information revisions.
Why it matters
This AD is critical for aviation professionals as it addresses a safety risk involving the main rotor swashplate assembly, a key component affecting helicopter control. Operators and maintenance organizations must implement the inspection requirements to detect early signs of fatigue and prevent catastrophic failure. Compliance ensures continued airworthiness and reduces the risk of in-flight loss of control incidents.
