## The airworthiness directive

65-05-02 DOUGLAS: Amdt. 39-39 Part 39 Federal Register February 25, 1965. Applies to Model DC-8 Series Aircraft Equipped with the Standard Wing Leading Edge Configuration, Except Aircraft with Serial Numbers 45687 to 45690 inclusive.

Compliance required as indicated.

As a result of failures of the upper outboard spar cap structure of the inboard pylons, accomplish the following:

  (a) Within the next 350 hours' time in service unless already accomplished, within the last 650 hours' time in service, inspect in accordance with (b) all inboard pylons having 8,000 or more hours' time in service as of the effective date of this AD. Prior to the accumulation of 8,350 hours' time in service unless already accomplished within the last 1,000 hours' time in service prior to the effective date of this AD, inspect in accordance with (b) all inboard pylons having less than 8,000 hours' time in service as of the effective date of this AD.

  (b) Gain access to the area to be inspected by removing outboard access door numbers 213 and 314. Inspect the outboard spar cap, P/N 5640144-1, of No. 2 inboard pylon and the outboard spar cap, P/N 5640144-2, of No. 3 pylon for evidence of cracks in the area of Stations Yip = 225.000 to Yip = 233.000. Use close visual or dye penetrant inspection methods.

  (c) If cracks are found, rework in accordance with paragraph 2 of Douglas Service Bulletin No. 54-34, Reissue No. 1, dated July 6, 1964, or an equivalent method approved by the Chief, Aircraft Engineering Division, FAA Western Region, before further flight.

  (d) If no cracks are found, reinspect parts as outlined in (b) at periods not to exceed 1,000 hours' time in service from the last inspection until reworked in accordance with paragraph 2 of Douglas Service Bulletin No. 54-34, Reissue No. 1, dated July 6, 1964, or an equivalent method approved by the Chief, Aircraft Engineering Division, FAA Western Region. The repetitive inspection may be discontinued onall parts reworked in accordance with (c) or (d).

  (e) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Aircraft Engineering Division, FAA Western Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator.

(Douglas DC-8 Service Bulletin No. 54-34, Reissue No. 1, dated July 6, 1964, covers this same subject.)

This directive effective March 26, 1965.
