AD/HU 369/85 Amdt 1 Main Rotor Blade Root Replacement 11/2009

Requirement:

CANCELLED.

This AD is cancelled on 22 October 2009.

Background:

This AD, raised in 1993 against McDonnell Douglas Helicopter Company Service Information Notices (SIN) No. DN-183.2, EN-75.2 and FN-62.2 required replacement of main rotor blades following cracking of blade root lugs.  Compliance was required no later than 30 September 1993.

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