To prevent the inflight loss of the wing-to-fuselage fairing, accomplish the following:
A. Conduct a daily visual inspection of wing-to-fuselage fairing, both right and left, for cracks or looseness around screws and grommets. If cracks or looseness is found, before further flight install washer P/N AN970-3, and use washer head screw P/N AN525-10R9 in place of P/N AN509-10R9. Daily inspections are to continue until the modification of the fairings, described in paragraph B., below, is accomplished.
NOTE: Caution should be used not to overtighten screws, as cracks may develop.
B. Modificationof the wing-to-fuselage fairings in accordance with Fairchild Service Bulletin F27-53-9, Revision 1, dated May 13, 1959, or later FAA-approved revisions, constitutes terminating action for the daily inspection requirement of paragraph A., above.
C. Alternate means of compliance or adjustment of compliance time, which provide an acceptable level of safety, may be used when approved by the Manager, New York Aircraft Certification Office, FAA, New England Region.
D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.
All persons affected by this airworthiness directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Fairchild Republic Company, Showalter Road, Hagerstown, Maryland 21740. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the FAA, New England Region, New York Aircraft Certification Office, 181 South Franklin Avenue, Room 202, Valley Stream, New York.
