## Analysis

THE PILOT/OWNER REPORTED THAT HE HAD THE LEFT MAIN LANDING GEAR REPAIRED TWICE PREVIOUSLY DUE TO LEFT GEAR COLLAPSES UPON LANDING. HE ALSO STATED THAT HE HAD JUST PICKED UP THE AIRCRAFT FROM THE MECHANIC PERFORMING THE LAST REPAIR. WHEN UPON THE FIRST LANDING THE LEFT GEAR AGAIN COLLAPSED. THE LEFT GEAR ATTACH BRACKET WAS FOUND TO HAVE BEEN RECENTLY REPLACED AND WAS OUT OF ALIGNMENT. THIS CAUSED THE LEFT GEAR TO NOT EXTEND FULLY AND LOCK. THE MECHANIC WHO PERFORMED THE MAINTENCE FAILED TO PROPERLY REPAIR THE GEAR AND ALSO FAILED TO COMPLETE THE REQUIRED RECORD ENTRIES.
