## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN THE PROPER LANDING DESCENT RATE AND THE RESULTANT RIGHT MAIN LANDING GEAR ASSEMBLY COLLAPSE.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - landing gear,tire - burst
  - proper descent rate - not maintained, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, landing - roll
  - landing gear,main gear - overload (cause)
- Main gear collapsed, landing - roll

## Analysis

THE AIRCRAFT COMPLETED AN INSTRUMENT APPROACH AND LANDED HARD ON THE RUNWAY SURFACE FIRST WITH THE LEFT GEAR THEN THE RIGHT GEAR.  THE TIRES BURST AND THE LOWER FUSELAGE CAME INTO CONTACT WITH THE RUNWAY SURFACE. AFTER THE NOSE GEAR TOUCHED DOWN, THE RIGHT MAIN LANDING GEAR COLLAPSED AND THE PILOT LOST CONTROL OF THE AIRCRAFT.  IT VEERED TO THE LEFT AND DEPARTED THE RUNWAY, COMING TO REST APPROXIMATELY 150 TO 200 YARDS FROM THE POINT OF DEPARTURE.  INITIAL TOUCH DOWN OCCURRED ABOUT 12 FEET FROM THE THRESHOLD, TEN FEET LEFT OF CENTERLINE.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
