AIRWORTHINESS DIRECTIVE

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-76/39 Amdt 1.

Sikorsky S-76 Series Helicopters

AD/S-76/39 Amdt 1 Main Rotor Blade Tip Block and Tip End Assemblies - Inspection and Rectification 7/2009

Requirement:

CANCELLED.

This AD is cancelled on 2 July 2009.

Background:

This AD, raised in 1985 against Sikorsky Alert Service Bulletin (ASB) 76-65-35 Amdt 1, required a one-time inspection of main rotor blade tip block and tip end assemblies following a manufacturer report of an operator experiencing loss of a main rotor blade tip block.  Compliance was required not later than 1 May 1986.

As all affected aircraft would have been inspected, and, if necessary, modified long ago, this AD is no longer required.
