Plain English Summary

3/10 complexity

This instrument amends an existing airworthiness directive for British Aerospace Jetstream Series 3100 aeroplanes to require compliance with Jetstream Aircraft Alert Service Bulletin 57-A-JA 880144 Revision 2, effective 10 October 1996. Aircraft with modification JM5303 are excluded; previously set inspection intervals remain unchanged.

It targets operators/owners of affected aeroplanes, who must bear the cost and follow the revised bulletin’s inspections and corrective actions to address reported cracking at wing rib 36 and to replace potentially misleading earlier instructions.

Amdt 1

Shear Angles at Wing Rib 36 11/96

Applicability: Jetstream Series 3100 series aircraft, that do not have modification JM5303 embodied.

Requirement: Action in accordance with Jetstream Aircraft Alert Service Bulletin 57-A-JA 880144 Revision 2.

Compliance: As specified in the requirement document.

The compliance of the initial issue of this directive remains unchanged for the inspection intervals. This amendment is effective from 10 October 1996.

Background: The cracking of shear angles was reported, and also detected by Jetstream fatigue testing.

Amendment 1 is raised in response to the latest revision of the requirement document which is issued because the Accomplishment Instructions at the previous issue standard are potentially misleading.

The original issue of this airworthiness directive became effective on 6 October 1988.
