AD 84-03-02

84-03-02 McDONNELL DOUGLAS: Amendment 39-4813. Applies to McDonnell Douglas Model DC-10-30, -30F, -40, and KC-10A (Military) series airplanes, certificated in all categories, equipped with Goodyear P/N 6002870 antiskid control unit. Compliance required as indicated, unless previously accomplished.

To prevent undetected severe loss of braking ability, accomplish the following:

A. Compliance required within 30 days after the effective date of this AD. Revise the Limitations Section of the FAA approved Airplane Flight Manual by adding a paragraph which reads as follows:

"Prior to each takeoff, turn the ANTISKID ARM switch in the cockpit from the ARM position to the OFF position, then back to the ARM position. Within sixty (60) seconds thereafter, initiate the ANTISKID TEST function using the cockpit test switch. Verify that no antiskid fail lights remain illuminated on the annunciator panel."

NOTE: A copy of this AD may be inserted in the AFM as an acceptable means of compliance with the required AFM revision.

B. Compliance required within 3000 flight hours after the effective date of this AD. Modify Goodyear P/N 6002870 antiskid control unit in accordance with the Accomplishment Instructions of Douglas DC-10 Alert Service Bulletin A32-202, dated November 30, 1983, and Goodyear Service Bulletin DC-10-30/40-32-36, dated July 29, 1983, or later revisions approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. Modification of the antiskid control unit as specified above constitutes terminating action for this AD and the interim AFM revision required by paragraph A., above, may be removed.

C. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain 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 directive who have not already received these documents from the manufacturer may obtain copies upon request to McDonnell Douglas Corporation, 3855 Lakewood Boulevard, Long Beach, California 90846, Attention: Director, Publications and Training, C1-750 (54-60). These documents also may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Los Angeles Aircraft Certification Office, 4344 Donald Douglas Drive, Long Beach, California.

This amendment becomes effective February 27, 1984.
