REGULATORY TEXT:  
86-19-51 MCDONNELL DOUGLAS: Amendment 39-5491. Applies to Model DC-9-80 series airplanes; fuselage numbers 1243 through 1259, 1261 through 1286, 1289 through 1291, 1293 through 1299, 1301 through 1304, and 1306; certificated in any category.

To prevent elevator jamming, which could result in the loss of adequate aircraft control, accomplish the following, unless previously accomplished:

A. Within 6 calendar days after the effective date of this AD:

1. Open access doors 3507 and 3608 to gain access to inspection area on the lower elevator surface, in accordance with DC-9-80 Maintenance Manual, Chapter 6-23-00.

2. Visually inspect the left and right elevator hydraulic boost cylinder attach rod ends and verify that the retaining nut and cotter pin are installed.

3. If rod end washer, nut, and/or cotter pin are missing, install new PLI-8-13.5 washer, 83494-820 nut, and MS24665-302 cotter pin, as necessary, as follows:

Tighten nut to a torque of 250-270 inch-pounds. If slot in nut and cotter pin hole in rod end align, install cotter pin. If slot in nut and cotter pin hole in rod end do not align, tighten nut a minimum amount required to obtain alignment (60 degrees maximum) to next slot and install cotter pin. Ring on PLI washer must be free to rotate after cotter pin installation. Cotter pin hole direction is machined on end of rod end for use as an installation aid.

B. Alternate means of compliance which provides an acceptable level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

All persons affected by this directive who have not already received the appropriate service information 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-L65 (54-60). These documents 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 January 2, 1987, as to all persons except those persons to whom it was made immediately effective by telegraphic AD T86-19-51, issued September 25, 1986.
