Résumé
We propose to supersede airworthiness directive (AD) 2014-07- 04R1 for certain Sikorsky Model S-92A helicopters. AD 2014-07-04R1 currently requires 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. Since we issued AD 2014-07-04R1, the manufacturer has developed an alteration that corrects the unsafe condition described in AD 2014-07-04R1. This proposed AD would require altering the wiring system in the upper deck area. These proposed actions are intended to prevent a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter.
