Schweizer (Hughes) 269 Series Helicopters

AD/HU 269/72 Idler Pulley Support Bracket - Inspection 6/2009

Requirement:

CANCELLED.

This AD is cancelled on 4 June 2009.

Background:

This AD, raised in 1988 against McDonnell Douglas Helicopter Company Service Information Notice (SIN) No. EN-40 and FN-29, required a modification to prevent cracking at the outboard ends of the horizontal stabiliser tabs as a result of vibration.  Compliance was required by 1 March 1988.

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