Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The YS-11 was landing with a right crosswind. The pilot said he touched down on the right main landing gear first and upon touchdown, the right main landing gear collapsed. The aircraft stayed on the runway and received minor damage. The cockpit crew of 2, 2 flight attendants, 7 revenue passengers and 12 non-revenue passengers (a graduating glass of flight attendants) were not injured during the subsequent evacuation of the aircraft. Examination of the landing gear trunion disclosed a stress fracture and heavy corrosion. The corrosion produced pitting which can be a source of stress. The landing gear had been overhauled in accordance with recommended procedures which include corrosion preventative measures. The corrosion was not detected during normal inspections.
