Compliance: Required as indicated, unless accomplished previously.

To prevent reduced structural integrity of the wings, accomplish the following:

(1) If any corroded parts are found in which the corrosion is within the limits specified in British Aerospace Service Bulletin S.B. 57-73, dated July 30, 1991, prior to further flight, repair in accordance with that service bulletin.

(2) If any corroded parts are found in which the corrosion exceeds the limits specified in British Aerospace Service Bulletin S.B. 57-73, dated July 30, 1991, prior to further flight, repair in accordance with a method approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.
