The airworthiness directive
76-17-04 ARMSTRONG WHITWORTH: Amendment 39-2701. Applies to all Model AW-650 Series 101 airplanes certificated in all categories.
Compliance is required within the next 100 hours time in service after the effective date of this AD, unless already accomplished.
To detect cracks in the undercut at the bottom of the main undercarriage sliding cylinder and prevent possible failure of the main landing gear, accomplish the following:
(a) Inspect the undercut at the bottom of the main undercarriage sliding cylinder with magnetic particle fluid in accordance with Accomplishment Instructions 2A(1) through 2A(6) of Dowty Rotol Service Bulletin No. 32-49D, dated August 15, 1975, or an FAA-approved equivalent.
(b) If a crack in the sliding cylinder is detected during the inspection required by paragraph (a) of this AD, replace the main undercarriage sliding cylinder before further flight with a serviceable part of the same part number or an FAA-approved equivalent.
This amendment becomes effective on September 9, 1976.
