What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Tom garber a part owner and pilot, jump started the airplane because of a weak battery; he set the parking brakes and held the toe brakes during the start. Mr. Coffman then got into the right seat while the other pilot exited the left seat. Then Mr. Coffman moved over to the left seat and buckled in. After a briefing from the owner, he released the parking brake; the aircraft required a lot of power before it started moving forward. As the aircraft was moving and turning left, Mr. Coffman tested the brakes; the right brake was not effective and the airplane continued to turn left. The pilot tried to stop the airplane by shutting down the engine, but the propeller was still turning when it struck the nose of a parked falcon 20. The aircraft had been sitting in storage for several months before this flight, so the wheels and brakes were stiff and tended to grab. When the pilot turned left out of parking, the nose wheel cocked beyond ninety degrees and the extra power used to break away from parking carried the airplane on through the turn and into the parked falcon 20.
As the FAA filed it
(-23) TOM GARBER A PART OWNER AND PILOT, JUMP STARTED THE AIRPLANE BECAUSE OF A WEAK BATTERY; HE SET THE PARKING BRAKES AND HELD THE TOE BRAKES DURING THE START. MR. COFFMAN THEN GOT INTO THE RIGHT SEAT WHILE THE OTHER PILOT EXITED THE LEFT SEAT. THEN MR. COFFMAN MOVED OVER TO THE LEFT SEAT AND BUCKLED IN. AFTER A BRIEFING FROM THE OWNER, HE RELEASED THE PARKING BRAKE; THE AIRCRAFT REQUIRED A LOT OF POWER BEFORE IT STARTED MOVING FORWARD. AS THE AIRCRAFT WAS MOVING AND TURNING LEFT, MR. COFFMAN TESTED THE BRAKES; THE RIGHT BRAKE WAS NOT EFFECTIVE AND THE AIRPLANE CONTINUED TO TURN LEFT. THE PILOT TRIED TO STOP THE AIRPLANE BY SHUTTING DOWN THE ENGINE, BUT THE PROPELLER WAS STILL TURNING WHEN IT STRUCK THE NOSE OF A PARKED FALCON 20. THE AIRCRAFT HAD BEEN SITTING IN STORAGE FOR SEVERAL MONTHS BEFORE THIS FLIGHT, SO THE WHEELS AND BRAKES WERE STIFF AND TENDED TO GRAB. WHEN THE PILOT TURNED LEFT OUT OF PARKING, THE NOSE WHEEL COCKED BEYOND NINETY DEGREES AND THE EXTRA POWER USED TO BREAK AWAY FROM PARKING CARRIED THE AIRPLANE ON THROUGH THE TURN AND INTO THE PARKED FALCON 20.
