Probable cause
The inadequate lubrication of the landing gear side strut assembly by company maintenance personnel. A factor in the accident was the inadequate design of the assembly that trapped water and prevented adequate lubrication.

Read the full NTSB narrative
A Boeing 727-200 received minor damage when the left main landing gear side strut separated during taxi. Examination of the right main landing gear revealed that the side strut assembly was separated from the main shock strut and that the gear door was open. The threaded portion of the main strut attachment clevis was separated from the side strut assembly. The clevis remained attached to the main shock strut. The clevis bolt was dry, corroded, and the threads were broken and stripped. There was no evidence of lubrication on the clevis bolt. The retaining nut and the lock nut inside the lower end of the side strut were also dry, corroded, and displayed corresponding damaged and stripped threads inside the lock nut. Metallurgical examination revealed the threads suffered severe corrosion damage prior to being stripped. The aircraft manufacturer stated that a re-design for the side strut assembly was in development to block moisture, prevent corrosion, and improve lubrication for the assembly.
