What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On January 5, 2000, Gulfstream aerospace G-1159A, N188TC, landed at its home base, Boeing field, Seattle, Washington. The passengers disembarked, and the crew taxied the aircraft to the runway to check the anti-skid system. While returning to the ramp, the right wing tip of the aircraft struck the tail of the unoccupied Learjet aircraft that had parked on the ramp subsequent to the Gulfstream's departure from the ramp. This caused damage to both aircraft. A ramp person was running towards the Gulfstream to assist in marshalling the aircraft for parking, but had not yet arrived when the collision occurred. The Learjet was parked in such a manner that arriving aircraft had to taxi behind it in order to get to the executive flight terminal.
As the FAA filed it
(-23) ON JANUARY 5, 2000, GULFSTREAM AEROSPACE G-1159A, N188TC, LANDED AT ITS HOME BASE, BOEING FIELD, SEATTLE, WASHINGTON. THE PASSENGERS DISEMBARKED, AND THE CREW TAXIED THE AIRCRAFT TO THE RUNWAY TO CHECK THE ANTI-SKID SYSTEM. WHILE RETURNING TO THE RAMP, THE RIGHT WING TIP OF THE AIRCRAFT STRUCK THE TAIL OF THE UNOCCUPIED LEARJET AIRCRAFT THAT HAD PARKED ON THE RAMP SUBSEQUENT TO THE GULFSTREAM'S DEPARTURE FROM THE RAMP. THIS CAUSED DAMAGE TO BOTH AIRCRAFT. A RAMP PERSON WAS RUNNING TOWARDS THE GULFSTREAM TO ASSIST IN MARSHALLING THE AIRCRAFT FOR PARKING, BUT HAD NOT YET ARRIVED WHEN THE COLLISION OCCURRED. THE LEARJET WAS PARKED IN SUCH A MANNER THAT ARRIVING AIRCRAFT HAD TO TAXI BEHIND IT IN ORDER TO GET TO THE EXECUTIVE FLIGHT TERMINAL.
