| Applicability: | English production (C1) all models and Portuguese (T Mk 20) production models. |
|---|---|
| Requirement: | Action in accordance with British Aerospace T.N.S. No. 161, Issue 3, dated 1 August 1985. |
| Compliance: | Within 100 hours time in service after the effective date of this AD or at the next scheduled inspection for Maintenance Release issued after the effective date of this AD, whichever is the later, and at any time the wing attachment links are removed. |
| This Amendment becomes effective on 21 June 2011. | |
| Background: | Cases have been reported where the wing to fuselage attachment links have been fitted out of alignment resulting in chafing of the spar and/or tie bar, by the links.Amendment 1 of this AD revised the requirements to reflect Issue 3 of the Requirement Document which revised the shimming procedure.This amendment is issued to include the Portuguese manufactured Chipmunk (T Mk 20) in the applicability of the AD. A recent review indicates that TNS 161 may be applicable to T Mk 20 Chipmunks, depending on the wing attach fitting part number fitted to the aircraft. This part number will need to be determined by a physical inspection or aircraft records.There is no change to the requirements or compliance (except to require compliance after the effective date of this amendment). |
