## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) AT 1541E, N4820K, A NAVION, WAS AT THE LOWER WEST RAMP AND STARTING TO TAXI TO RUNWAY 28 WHEN THE GEAR COLLAPSED. INVESTIGATION REVEALED THAT THE PILOT SELECTED THE HYDRAULIC PUMP SWITCH TO THE ON POSITION WITH THE LANDING GEAR HANDLE IN THE UP POSITION; THE MAIN LANDING GEAR COLLAPSED CAUSING DAMAGE TO THE AIRCRAFT. THE PILOT, THE SOLE OCCUPANT OF THE AIRCRAFT, WAS NOT INJURED.
