REGULATORY TEXT:  
53-10-02 de HAVILLAND: Applies to Model DHC-2 (Beaver) Aircraft, Serial Numbers 1 to 401 Inclusive.

Compliance required as indicated.

After the aircraft has acquired 500 hours of flying time and pending the incorporation of the recommended repair, the wings should be inspected for cracks in lower wing skin at ends of the short stringers at the root end station of the wing leading edges at 50-hour intervals. If no cracks are evident reinforcements should be installed on the bottom surface of the wing as a preventive measure. The FAA concurs in this mandatory action by the Canadian Department of Transport.

(de Havilland Technical News Sheet Series B, No. 59 - Issue 2 dated January 15, 1953, available from de Havilland Aircraft of Canada, Ltd., Toronto, Ontario, Canada, covers this same subject and describes method of reinforcement.)
