REGULATORY TEXT:  
82-27-05 McDONNELL DOUGLAS: Amendment 39-4525. Applies to McDonnell Douglas Model DC-8 series airplanes, fuselage numbers 520 through 556, and prior airplanes modified in accordance with McDonnell Douglas DC-8 Service Bulletin 32-156, dated June 12, 1970, certificated in all categories. Compliance required as indicated, unless previously accomplished.

To preclude excessive brake application on landing resulting from an unannunciated failure of the anti-skid system, accomplish the following:

A. Within 30 days from the effective date of this AD install a placard in clear view of the flight engineer as close as practicable to the Number 1 DC load meter which reads, "With DC Bus 1 unpowered, Anti-Skid system and annunciator are inoperative."

B. Within 6 months from the effective date of this AD, modify the anti-skid control system circuitry in accordance with the Accomplishment Instructions of McDonnell Douglas DC-8 Service Bulletin 32-175, dated July 2, 1982, or later revisions approved by the Manager, Los Angeles Aircraft Certification Office, FAA Northwest Mountain Region.

NOTE: The following procedure may be used as an alternative to the anti-skid checkout procedure specified in paragraph 2.D. of Service Bulletin 32-175:

Restore electrical power and functionally test anti-skid off/fail (INOP) light circuitry as follows:

1. Verify parking brake is released.

2. Place anti-skid switch S1-352 located on engine instrument panel to "ARM." Verify anti-skid off/fail (INOP) light on captain's instrument panel is not illuminated.

3. At EPC circuit breaker panel, 28 volt DC Bus 1 miscellaneous section, open circuit breaker B1-406, "LANDING GEAR WARN AND INTERLOCK" and at 28 VDC Bus 1 Heat, Vent, Ice Protection Section, open circuit breaker B1-820, Left, Right, and NLG and MAIN DOORS WARNING. Verify anti-skid off/fail (INOP) light is illuminated.

4. Close circuit breaker B1-406 and B1-820 to restore system to normal condition.

5. Return parking brake to original position.

6. Remove placard installed per paragraph A., above.

C. Alternative means of compliance providing 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.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).

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 FAA, Northwest Mountain Region, 17900 Pacific Highway South, C-68966, Seattle, Washington 98168, or Los Angeles Aircraft Certification Office, 4344 Donald Douglas Drive, Long Beach, California 90808.

This amendment becomes effective January 3, 1983.
