Analysis
During gear extn for lndg, the flt crew noted a 'loud & very noticeable jolting of the acft.' Shortly thereafter, they also noticed that a portion of the right main gear had punctured the upper surface of the rgt wing. The crew then declared an emergency & made an uneventful lndg. An investigation revealed the rgt main gear actuator support link, pn 65-19657-5, had become corroded & failed. The outboard end of the main gear actuator beam then punctured the upper wing panel. Also a hydraulic line was severed, which disabled the 'a' hydraulic sys. Maintenance records from the previous acft owner erroneously indicated that in 1971, the failed part had been replaced with a newer link assembly, pn 19657-11, which did not require an inspection. Consequently, the required inspections specified in AD 68-17-01, regarding the failed link, had not been complied with by the new owner. Boeing had issued a svc bulletin (727-32-306) which recommended that link assemblies with pn 19657-5 (as well as -4, -8 & -13) be removed from svc & discarded.
