62-12-03 GENERAL DYNAMICS/CONVAIR: Amdt. 443 Part 507 Federal Register May 24, 1962. Applies to All Models 22 Aircraft With 3,000 Hours or More Time in Service.
Compliance required within the next 25 hours' time in service unless already accomplished within the last 125 hours' time in service and thereafter within each 150 hours' time in service from the last inspection.
Two recent cases of cracked inboard wing flap carriage support fittings P/N's 22-18703- 11 and -12 attributed to fatigue have been reported. To preclude operation with a cracked fitting, conduct close visual inspection of fittings P/N's 22-18703-11 and -12, and 22-18702-11 and -12 on the inboard flaps. Replace any cracked fitting prior to further flight.
When P/N's 22-18703-11 and -12 and 22-18702-11 and -12 on the inboard flaps are modified in accordance with General Dynamics Service Bulletin No. 27-63 or an FAA Western Region Engineering approved equivalent modification, the 150-hour repetitive inspections may be discontinued.
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.
(General Dynamics/Convair Telegraphic Alert Service Bulletin No. 27-58 and Service Bulletin No. 27-63 cover 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 telegram dated May 9, 1962.
Revised February 27, 1963.
