63-19-02 GENERAL DYNAMICS: Amdt. 619 Part 507 Federal Register September 19, 1963. Applies to All Models 30 and 30A Aircraft.
Compliance required as indicated.
(a) Within the next 50 hours' time in service after the effective date of this AD unless already accomplished within the last 950 hours' time in service, conduct a close visual inspection of the horizontal stabilizer trim control cables in order to detect frayed cable. Pay particular attention to the section of the cable in the vicinity of the aft pressure bulkhead. Replace all frayed or otherwise damaged horizontal stabilizer trim control cables with new cables before further flight.
(b) At periods not to exceed 1,000 hours' time in service after the inspection in (a), inspect the horizontal stabilizer nose down trim control cable on the aft side of the pressure bulkhead. This inspection shall include pulling the left-hand cable aft and flexing it several times in the area that normally contacts the pulley guiding the nose down cable. Replace cables having broken or damaged wires before further flight.
(c) The repetitive inspection in (b) may be discontinued when the horizontal stabilizer trim cable system has been reworked in accordance with an FAA Western Region approved modification.
(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.
This directive effective September 19, 1963.
