Parts Catalog P68B, Figure No. 5.2, Item No. 33; or Parts Catalog P68C, Figure No. 5.3, Item No. 36). NOTE: The correct torque value for these bolts is 0.9 to 0.950 Kpm; 78 to 83 in. lbs.

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

c) 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.
