## Narrative

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

DURING THE START-UP OF THE RIGHT ENGINE OF THE KING AIR (N438CA) BY THE PILOT IN COMMAND (PIC), THE SECOND IN COMMAND (SIC) VISUALLY CONFIRMED THAT THE AIRPLANE WAS STATIONARY BEFORE ATTEMPTING TO UNTANGLE HIS SHOULDER HARNESS FROM THE RIGHT SEAT. LESS THAN A MINUTE LATER, WHILE STARTING THE LEFT ENGINE, THE AIRPLANE COLLIDED WITH A PARKED COMPANY AIRPLANE (N902TS) IN FRONT OF IT, CAUSING SUBSTANTIAL DAMAGE TO N483CA. FORTUNATELY, THE TWO PILOTS AND TWO PASSENGERS WERE NOT INJURED. THE WEATHER THAT NIGHT WAS VISUAL METEOROLOGICAL CONDITIONS (VMC) WITH A LIGHT DRIZZLE, AND THE AIRPLANE'S STROBE AND BEACON LIGHTS WERE THE ONLY SOURCES OF ILLUMINATION. THE AIRCRAFT HAD BEEN WASHED BEFORE THE FLIGHT.
