Plain English Summary

5/10 complexity

This AD applies to HS 748 aeroplanes that have not incorporated Modification 7670 and mandates inspection of the aileron, rudder and elevator cable tension regulators and gust locks per BAe Mandatory Service Bulletin HS748‑27‑126 Revision 3. Compliance is within 400 flying hours or 6 months (whichever first) and must be repeated at those intervals until Service Bulletin HS748‑27‑129 (Mod 7670) is incorporated. The amendment introduces recurring inspection requirements at 400-hour/6-month intervals and an optional terminating modification (Mod 7670) that operators may elect to incorporate to cease repetitive inspections.

Applicability: All HS 748 aircraft without Modification 7670 incorporated.

Requirement: Inspect in accordance with BAe Systems Mandatory Service Bulletin HS748-27-126 Revision 3.

Note: UK CAA AD 005-02-96 refers.

Compliance: Unless already accomplished, within 400 flying hours or 6 months after 23 April 1998, whichever occurs first. Repeat thereafter at intervals not to exceed 400 flying hours or 6 months, whichever occurs first; until incorporation of Service Bulletin HS748-27-129 (modification 7670).

The initial inspection compliance time remains unchanged by this issue. This Amendment becomes effective on 29 November 2001.

Background: In-service experience has shown that it is possible for the aileron, rudder, and elevator cable tension regulators and gust locks to jam, leaving the associated primary control cable in an untensioned condition.

Amendment 1 is issued in response to the latest revision of the Requirement document, which introduces repetitive inspection requirements and optional terminating action for the repetitive inspections.

The original issue of this Airworthiness Directive became effective on 23 April 1998.
