Plain English Summary

3/10 complexity

This directive requires Australian-registered Beagle B121 (Pup) aeroplanes without Modification No. BE.214 to inspect and, if needed, repair the wing spar web immediately outboard of the root rib following Mandatory BAe Service Bulletin B121/79 Revision 1, after cracking was found. Compliance is moved earlier—from 2,000 to 1,300 flight hours (deadline 31 May 1991)—and owners/operators bear the inspection/repair costs or may embody Mod BE.214 to remove applicability.

Amdt 1

Wing Spar Web 6/91 DM

Applicability: All models not having Modification No. BE. 214 embodied. Requirement: Action in accordance with Mandatory BAe SB B121/79 Revision 1.

Compliance: As specified in the Requirement Document but with a revised accomplishment date of 31 May 1991 for Australian registered aircraft which have exceeded 1300 hours time in service.

Background: Overseas, cracking has been found on wing spar webs immediately outboard of the root rib. They have occurred on mainplanes which do not have Modification No. BE. 214 embodied.

This amendment is necessary to introduce the accomplishment of the bulletin at 1300 flying hours in lieu of the present 2000 flying hours, since cracks have been found on an aircraft during preparation for accomplishment of the bulletin at 2000 hours.

Compliance date required by UK CAA extended by two months.
