Airworthiness Directive · Amendment 39-18446 · Main hydraulic system
Sikorsky Aircraft Corporation (Sikorsky) Helicopters
This AD applies to Model S-92A helicopters, serial number 920006 through 920084, certificated in any category.
We are superseding Airworthiness Directive (AD) 2014-07-04R1 for certain Model S-92A helicopters. AD 2014-07-04R1 required repetitive inspections in the upper deck area for incorrectly installed clamps and chafing between the electrical wires and the hydraulic lines and replacing any unairworthy wires or hydraulic lines. This new AD requires altering the wiring system in the upper deck area to correct the unsafe condition described in AD 2014-07-04R1. We are issuing this AD to prevent a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Within 150 hours time-in-service, reroute the left hand and right hand upper deck wiring system by complying with the Instructions, paragraph B, of Sikorsky Aircraft Corporation Special Service Instructions SSI No. 92-070A, Revision A, dated April 25, 2014.
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.
