## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - electrical system,electric relay - binding(mechanical) (cause)
  - hydraulic system - binding(mechanical) (cause)
  - landing gear,normal retraction/extension assembly - inoperative (contributing factor)
  - gear extension - not possible, pilot in command (contributing factor)
- In flight collision with terrain/water, landing - flare/touchdown
  - wheels up landing - performed, pilot in command (contributing factor)

## Analysis

THE PLT REPORTED THAT WHEN THE LANDING GEAR HANDLE WAS MOVED TO THE UP POSITION, THE HYDRAULIC PUMP CONTINUED TO OPERATE. SUBSEQUENTLY, THE CIRCUIT BREAKER FOR THE PUMP WAS PULLED TO KEEP THE MOTOR FROM OVERHEATING. SEVERAL ATTEMPTS TO LOWER THE GEAR WITH THE NORMAL & EMERGENCY SYSTEMS WERE INEFFECTIVE, SO A GEAR UP LANDING WAS MADE ON A GRASS PORTION OF THE ARPT. AN EXAM OF THE LANDING GEAR SYSTEM REVEALED THAT THE SELECTOR VALVE IN THE SOLENOID, PN 210-61039, WAS STUCK. THIS PREVENTED MOVEMENT OF THE GEAR IN EITHER DIRECTION.
