Compliance required before April 10, 1979, unless already accomplished, or unless incorporated in production. To minimize the probability of an aborted takeoff resulting from a false stall warning during the takeoff roll, add a five second time delay between nose gear lift-off and the initiation of a stall warning by accomplishing the following: (a) Modify the airplanes in accordance with McDonnell Douglas DC-10 Service Bulletin 22-94 dated August 4, 1977, or later FAA approved revisions. (b) Incorporate revisions in the FAA Approved Airplane Flight Manual, Documents MDC-J1010, MDC-J1030, MDC-J5830, MDC-J1040 and MDC-J2140, by adding the following new heading and text in Section III Procedures: STALL WARNING PREFLIGHT CHECK Rotate "STALL TEST" switch to "L (MOM)." Note five second delay before stick shaker activation. Rotate "STALL TEST" switch to "R (MOM)." Again note five second delay before stick shaker activation. (c) Equivalent modifications, procedures, or revisions may be used when approved by the Chief, Aircraft Engineering Division, FAA Western Region. (d) Special flight permits may be issued in accordance with FAR's 21.197 and 21.199 to operate airplanes to a base for accomplishment of the modification required by this AD.
