Aircraft Accident/Incident Report
Denver, Colorado 80220

NTSB Narrative Summary Released at Completion of Accident
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.
