Plain English Summary

5/10 complexity

This Airworthiness Directive requires operators of aircraft fitted with Sutton shoulder harnesses to inspect front and rear cockpit harness installations using the procedure in British Aerospace Mandatory TNS CT(Moth) No.33 and to replace certain part-numbered harnesses per that same document. It applies to all Sutton shoulder harnesses (including but not limited to specified De Havilland types). Inspections and replacements have short, specified compliance windows because the AD responds to a UK fatal accident and reported hidden webbing deterioration.

Applicability: All Sutton shoulder harnesses.

Requirement: 1. Inspect integrity of the front and rear cockpit safety harness installations in accordance with Paragraph 2A of British Aerospace Mandatory TNS CT(Moth) No. 33 Issue 1 dated 1 March 1999.

For front and rear cockpit safety harnesses P/Ns H34804A, H33257A, 51764A, H20746 or H37544, replace in accordance with Paragraph 2D of British Aerospace Mandatory TNS CT(Moth) No. 33 Issue 1 dated 1 March 1999.

Compliance: 1. Within 10 flying hours or before 21 June 2002 whichever occurs first and thereafter at intervals not exceeding 12 months.

Within 9 years of the initial installation date of harness or, if the installation date is not known, within 150 flying hours or before 17 June 2002 whichever occurs first.

Background: Investigation into a fatal accident in UK revealed that the harness restraint cables and one lap strap near the stitching had failed during impact. Subsequent investigation revealed that the strength of the webbing had significantly deteriorated without any visual indication. Aircraft specific AD’s have previously been issued for DH60, DH82 and DH94 series aircraft. This AD has been raised to cover possible other aircraft types fitted with a Sutton harness.
