Tailboom Centre Attachment Fitting Assembly - Inspection

13/2002

Applicability: All models.

Requirement: 1. Inspect the tailboom centre attachment (saddle) fitting in accordance with Hughes SIN No. B-238 (for models 269A, 269A-1, 269B) and B-239 (for model 269C).

2. Check the thickness of the saddle fitting lugs. The thickness of the lugs that are nearer the tailboom should be equal to, or less than, the thickness of the lugs away from the tail-boom. If the lug thickness does not meet this condition, the saddle fitting must be retired from service within the next 100 hours time in service.

Note: FAA AD’s 91-05-18 and 93-21-03 refer.

Compliance: 1. As detailed in Hughes SIN No. B-238 or B-239 as applicable (depending on model).

2. Coincident with the initial inspection required by SIN No. B-238 or B-239.

This Amendment becomes effective on 26 December 2002.

Background: These inspections are required to prevent fatigue failure of the tailboom centre attachment fitting, which could result in loss of the tailboom of the helicopter. This amendment changes the requirement document from Hughes SIN No. N-165.1 (now cancelled) to Hughes SIN B-239 or B-239 (depending on the model). Minor changes are also made to the text and a note added which refers to the original FAA AD’s.

There is no technical change to the inspections required by this AD.
