A. Within 48 hours after the effective date of this AD:

1. Insert the following into the Limitations Section of the FAA-approved Airplane Flight Manual (AFM), under paragraph 8.C., Automatic Flight Control System, and notify all crewmembers: "Flight director approaches and autopilot coupled approaches are not permitted without a valid radio altimeter."

NOTE: This may be accomplished by inserting a copy of Canadair, Ltd., Airplane Flight Manual PSP 601A-1, Temporary Revision No. 601/13, dated April 6, 1988, into the AFM.

2. Install a placard in the cockpit, visible to the pilot, stating: "FLIGHT DIRECTOR APPROACHES AND AUTOPILOT COUPLED APPROACHES PROHIBITED WITHOUT A VALID RADIO ALTIMETER."

Installation of Sperry/Honeywell Flight Guidance Computer, P/N 7003974-715, in accordance with Paragraph 2 of Canadair, Ltd., Service Bulletin 601-0276, dated May 10, 1988, constitutes terminating action for the requirements of paragraph A., above, and the temporary AFM revision and placard should be removed.

C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, New York Aircraft Certification Office, FAA, New England Region.

NOTE: The request should be forwarded through an FAA Principal Operations Inspector (POI) or Principal Avionics Inspector (PAI), as appropriate, who may add comments and then send it to the Manager, New York Aircraft Certification Office.

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 directive who have not already received the appropriate service information from the manufacturer may obtain copies upon request to Canadair, Ltd., Commercial Aircraft Technical Services, P.O.
