On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/S-76/38.
Sikorsky S-76 Series Helicopters
| AD/S-76/38 | Main Rotor Gear Box No. 1 and No. 2 Input Bevel Pinion Housing Assemblies - Inspection | 7/2009 |
Requirement: | CANCELLED. |
| This AD is cancelled on 2 July 2009. | |
Background: | This unique Australian AD raised in 1985 against Sikorsky Service Bulletin (SB) Compliance was: 1. Prior to issue of an Certificate of Airworthiness; or 2. Prior to the installation of a Main Rotor Gearboxes (MRGB) called up in the requirement document. This AD has been sufficiently promulgated for the affected MRGB to have been modified by now; therefore this AD is considered to be no longer required. |
