## Probable cause

THE FAILURE OF THE LEFT MAIN LANDING GEAR SADDLE.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Main gear collapsed, landing - flare/touchdown
  - landing gear,main gear attachment - failure,total (cause)
- Loss of control - on ground/water, landing - roll
  - directional control - not possible, pilot in command
- On ground/water collision with object, landing - roll
  - object - runway light

## Analysis

THE PILOT SAID THE FLIGHT WAS INBOUND FOR LANDING WHEN HE EXPERIENCED DIFFICULTY IN EXTENDING THE LANDING GEAR. THE AIRCRAFT LANDED ON THE RUNWAY, THE LEFT MAIN LANDING GEAR COLLAPSED AND THE AIRCRAFT SLID INTO A RUNWAY LIGHT STRUCTURE. POST ACCIDENT INSPECTION OF THE AIRCRAFT BY FAA AIRWORTHINESS INSPECTORS REVEALED THAT THE MAIN LANDING GEAR SADDLE CASTING HAD FAILED, LEAVING THE LEFT MAIN LANDING GEAR WITHOUT SUPPORT. THE LANDING GEAR SADDLE STRUCTURE ON THIS AIRCRAFT IS THE SUBJECT OF AN AIRWORTHINESS DIRECTIVE WHICH REQUIRES REPETITIVE INSPECTIONS FOR CRACKS. THE MAINTENANCE RECORDS REVEALED THAT THE AD HAD BEEN COMPLIED WITH ON THE LAST ANNUAL INSPECTION, 42 HOURS AND 3 MONTHS PRIOR TO THE ACCIDENT. THE FAA INSPECTOR NOTED THAT THE SADDLE CASTING HAD ABUNDANT EVIDENCE OF A RECENT DIE PENETRANT INSPECTION.
