REGULATORY TEXT:   62-09-01 BOEING: Amdt. 426 Part 507 Federal Register April 19, 1962. Applies to All Models 707 and 720 Aircraft Serial Numbers 17586-17652, 17658-17690, 17692-17724, 17903- 17930, 18012-18037, 18041-18050, 18054-18071, 18083-18085, 18154, 18167, 18334, 18351- 18353, 18381-18384, With More Than Or Upon Accumulation of 1,500 Hours' Time In Service.

Compliance required as indicated.

To prevent failure of control cable pressure seals which can cause jamming or dislodging of the cable, accomplish the following:

(a) Unless already accomplished within the last 300 hours' time in service, within the next 65 hours' time in service and at periods thereafter not to exceed 360 hours' time in service from the last inspection, conduct a close visual inspection of all control cable pressure seals except those for engine control cables, landing gear and landing gear door cables.

(b) Unless already accomplished within the last 360 hours' time in service, within the next 360 hours' time in service and at periods thereafter not to exceed 720 hours' time in service from the last inspection, conduct a close visual inspection of the nose wheel steering cable pressure seals.

(c) All seals which have failed or which show evidence of cracking, abnormal swelling or sponginess, or other signs of deterioration which could lead to seal failure shall be replaced with new seals prior to further flight.

(d) Replacement seals of the same part number shall be inspected in accordance with (a) or (b) prior to the accumulation of 1,500 hours' time in service and at intervals not to exceed 360 hours' time in service thereafter for flight control cable pressure seals and 720 hours' time in service thereafter for the nose wheel steering cable pressure seals.

(e) The special periodic inspection of any S11K-3R, S11K-4R, or S11R-4R seal may be discontinued upon replacement with a new type seal P/N S11K-3RA, S11K-4RA, or S11R-4RA respectively, together with a seal retention assembly installed in accordance with Boeing Service Bulletin No. 1358 for flight control systems, Boeing Service Bulletin No. 1737 for nose wheel steering systems, or FAA approved equivalent.

(f) 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.

(Boeing Service Bulletins Nos. 1358 and 1737 pertain to this same subject).

This directive effective upon publication in the Federal Register for all persons except those to whom it was made effective immediately by telegrams dated April 3, 1962, and April 6, 1962.
