REGULATORY TEXT:  
62-24-04 DOUGLAS: Amdt. 504 Part 507 Federal Register November 8, 1962. Applies to All Model DC-8 Aircraft With Midwing Flap Actuating Cylinder Douglas P/N 3643685. These Cylinders Can Be Identified as Having an Outside Diameter of 3.810-3.820 Inches at the Forward End of the Barrel Where the Cylinders Attach to the Wing Flap Crank.

Compliance required as indicated.

(a) On aircraft incorporating flap travel limit stops per paragraphs (a) and (b) of AD 62-16-02, the wing flaps shall be lowered with hydraulic pressure from the auxiliary pump and a close visual inspection of the forward 1/4 inch of length and around the entire periphery of both midwing flap actuating cylinder barrels shall be made daily for evidence of cracks or fluid leakage. Barrels exhibiting leakage or evidence of cracks shall be replaced prior to further flight.

(b) On aircraft not incorporating flap travel limit stops per AD 62-16-02, the inspections prescribed by (a) shall be accomplished prior to each flight.

(c) The inspections prescribed by (a) and (b) may be discontinued when the midwing wing flap cylinders P/N 3643685 are inspected and reworked in the manner described in Figure 1 of Douglas DC-8 Service Bulletin No. 27-134 for the outboard wing flap cylinders. Midwing wing flap cylinders inspected and reworked by operators in this manner will be subject to the inspection requirements prescribed for the outboard wing flap cylinders by paragraph 1.D(2) of Service Bulletin 27-134. Cylinders reworked by the operator shall in addition to the identification prescribed by Service Bulletin 27-134, be further identified by a color code or FAA approved equivalent.

(d) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, 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. 27-134 covers this same subject.)

This directive effective upon publication in the Federal Register for all person except those to whom it was made effective immediately by telegram dated October 19, 1962.
