## Sequence of events

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

- Airframe/component/system failure/malfunction, cruise - normal
  - landing gear,normal retraction/extension assembly - failure,partial (cause)
  - landing gear,normal retraction/extension assembly - fatigue (cause)
- Gear not extended, landing - flare/touchdown
- In flight collision with terrain/water, landing - flare/touchdown

## Analysis

WHILE IN CRUISE FLIGHT THE PILOT ATTEMPTED TO LOWER THE LANDING GEAR AND THE RIGHT MAIN LANDING GEAR WOULD NOT EXTEND. DURING THIS PROCESS THE AIRCRAFT GENERATOR WENT OFF THE LINE. THE PILOT ATTEMPTED TO MANUALLY LOWER THE LANDING GEAR AND EXTENDED THE NOSE GEAR EXTENDED AND THE LEFT MAIN GEAR EXTENDED, BUT THE RIGHT GEAR STILL DID NOT EXTEND. THE PILOT LANDED THE AIRCRAFT AND THE AIRCRAFT SLID OFF THE RUNWAY AND WAS SUBSTANTIALLY DAMAGED. POST ACCIDENT EXAMINATION OF THE RIGHT LANDING GEAR HYDRAULIC ACTUATOR REVEALED THAT IT WAS CRACKED IN FATIGUE. THIS ALLOWED THE HYDRAULIC FLUID TO BE PUMPED OVERBOARD AND CAUSED THE ACTUATOR TO NOT EXTEND THE RIGHT MAIN GEAR.
