## Probable cause

LEFT MAIN GEAR COLLAPSED DUE TO POOR MAINTENANCE.

## Sequence of events

## Analysis

THE ACFT TOUCHED DOWN & THE LEFT MAIN GEAR COLLAPSED. INVESTIGATION REVEALED NO WORN OR IMPROPER PARTS, BUT THE GEAR WAS 'EXTREMELY DRY' OF LUBRICANT. AFTER THE GEAR WAS LUBED, THE GEAR PERFORMED NORMALLY. THE ACFT HAD ABOUT 11 MONTHS & 152 HRS SINCE THE LAST ANNUAL INSP.
