32-A-JA851226 TITLE: LANDING GEAR - TO INTRODUCE NDT AND VISUAL INSPECTIONS OF MAIN LANDING GEAR PINTLE HOUSING FOR CRACKS.
AMENDMENT JA 851226
INSPECTION
1. PLANNING INFORMATION A. Effectivity All HP 137 Mk1 Aircraft and Jetstream Series 200 Aircraft. Jetstream Series 3100 aircraft fitted with main landing gears as defined in APPH Service Bulletin 32-19 Revision 4 and APPH Service Bulletin 32-40 (this inspection service bulletin applies to main landing gears with a microswitch hole in the cylinder).
B. Reason Cases have been reported of cracks in the yoke pintle housing for the landing gear attachment spigot of the main leg forging. The cracks were found during routine landing gear removal, and have been attributed to stress corrosion. Inspections are required to prevent hazardous development of cracks.
In those legs incorporating a hole for the microswitch, in-service cracking of the main landing gear cylinder has been reported during routine landing gear removal. The cracking is in the vicinity of the yoke pintle housing.
The cracking was due to fatigue. If left unchecked these cracks could grow to such an extent that structural failure of the main landing gear could occur.
C. Description This Inspection Service Bulletin (ISB) introduces APPH Service Bulletin (SB) 32-19 Revision 4 and APPH SB 32-40, which calls for NDT inspections of the pintle housings on the main landing gear for cracks. In order to carry out the NDT inspections it is necessary to remove the main landing gear legs.
Revision 5 of this ISB introduces an additional instruction to remove and subsequently reinstall the special washer, to improve access to carry out the inspection, on those aircraft that are post mod JM7862.
