Probable cause

The failure of the right main gear strut due to an improper weld repair by maintenance personnel.

NTSB narrative

According to the pilot, during landing the right main gear collapsed, and the airplane skidded off the runway to the right. Examination of the airplane found the right main gear failed at an improper weld repair on the main strut. A review of the Landing Gear Repair Manual 4-102, Page 4-73, AC 43.13-1B, showed that the repair of the landing gear should include the use of a two-piece reinforcement sleeve made of the same material and at least the same gauge as the damaged tube. The repair made on the main strut had neither, with a single bead of weld across a crack in the strut.
