REGULATORY TEXT:  
83-14-02 PILATUS BRITTEN-NORMAN, LTD.: Amendment 39-4682. Applies to BN-2A MK. III Trislander Series (S/Ns 1001 thru 1042, 1048 thru 1054, 1057 thru 1061, 350, 360, 361 and 363) airplanes certificated in any category.

Compliance: Required within the next 500 hours time-in-service after the effective date of this AD, unless already accomplished.

To prevent defects in the wing attachment pins which can adversely affect the safe life of the wing-to-fuselage attachments, accomplish the following:

(a) Remove the wing attachment pins, one at a time, in accordance with the instructions contained in the "ACTION" section of the Pilatus Britten-Norman, Ltd., Service Bulletin No. BN2/SB 146, Issue 1, dated December 31, 1980 (hereinafter referred to as the SB), or an FAA-approved equivalent.

(b) Visually inspect the wing attachment pins for corrosion, fretmarks, file/grinding marks and thread binding of the inboard nut in accordance with the instructions contained in the "ACTION" section of the SB, and if defects are found, before further flight, replace the defective wing attachment pins with new attachment pins.

NOTE: Refer to SB and Trislander Illustrated Parts Catalog (Pub. Ref. PC/2, Sec. 3.5./1).

(c) Visually inspect the wing joint gaps to ensure shim washers fill the gaps, and before further flight, replace shim washers as required to fill the wing joint gaps.

NOTE: Refer to SB and Trislander Maintenance Manual (Pub. Ref. MM/2).

(d) Reinstall wing attachment pins in accordance with the instructions contained in the "ACTION" section of the SB.

(e) Aircraft may be flown in accordance with Federal Aviation Regulation 21.197 to a location where this AD can be accomplished.

(f) An equivalent method of compliance with this AD, if used, must be approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, 1000 Brussels, Belgium.

This amendment becomes effective on August 19, 1983.
