REGULATORY TEXT:  
67-27-05 MCDONNELL DOUGLAS: Amdt. 39-486 Part 39 Federal Register September 26, 1967. Applies to Model DC-9 Series airplanes delivered prior to September 8, 1967.

Compliance required prior to the next departure from a maintenance base where the inspection can be accomplished by the operator but not later than 5 hours' time in service after September 26, 1967, unless already accomplished in accordance with Douglas Alert Service Bulletin No. A54-15 dated September 12, 1967, or wire constituting said Service Bulletin dated September 11, 1967, or later FAA-approved revision.

Due to a report of a missing bolt in the area where the engine aft mount attaches to the spar cap of the pylon rear spar (which was attributed to the absence of a bolt hole in the clip located on the aft side of the pylon rear spar), accomplish the following:

1. Inspect the outboard end of the upper and lower spar cap of each pylon rear spar in the vicinity of the first fastener inboard of the holes to which the rear engine mount attaches.

2. Replace any missing bolt or nut before further flight with a bolt (P/N MS 21250-05010) and/or nut (P/N H16-5), except that the airplane may be flown in accordance with FAR 21.197 to a base where the replacement can be accomplished.

3. Report in writing any instances of a missing bolt or nut to Chief, Aircraft Engineering Division, FAA Western Region, within three (3) days after discovery.

This amendment effective on September 26, 1967, for all persons except those to whom it was made effective immediately by telegram dated September 11, 1967.
