The aircraft sustained minor damage and there were no injuries. Post incident inspection found the right magneto seized, and this caused the engine to quit. The nosewheel was not locked over center because the right engine operates the only hydraulic pump. On 5/12/1998 aircraft N617GA, a Dassault Falcon 20, overran the runway during an aborted takeoff and sustained serious damage. The NTSB found the: “Probable cause(s) of this accident to be: “the pilot-in-command's inability to rotate during takeoff due to restricted movement of the elevator controls for undetermined reasons”. The aircraft was returned to service and was subsequently involved in a second accident (see below). On 12/10/1998 aircraft N615GA, a Fairchild Swearingen Metroliner, veered sharply off the runway during landing rollout. The aircraft departed the runway to the left coming to rest perpendicular to and off the runway. On 8/25/1999 aircraft N618GA, a Dassault Falcon 20, experienced a door opening during flight causing foreign object damage to the number one engine. After takeoff the cargo door opened and number one engine was “fodded” with a cargo liner. Post incident investigation found the door warning/latch system was operating properly. On 11/12/1999 aircraft N615GA, a Fairchild Swearingen Metroliner, skidded off the runway during landing after the left brake locked coming to rest 50 into grass. Post incident investigation found water in left brake assembly. On 4/4/2000 aircraft N175GA, a Dassault Falcon 20, experienced a landing gear collapse after attempting and emergency landing gear extension. The NTSB found: "The failure of the PIC to execute the complete procedure for emergency extension of the landing gear and the subsequent landing with the left main landing gear not locked fully down, resulting in an excursion off the runway and collision with a runway stanchion. A factor in the incident was the fatigue failure of the left MLG door hydraulic emergency slide valve bolts due to non-compliance with a 1984 factory service bulletin that recommended replacement with larger bolts”. On 6/13/2000 aircraft N184GA, a Dassault Falcon 20, was destroyed while making a third landing attempt at the Peterborough, Canada Airport. According to the Transportation Safety Board of Canada nearing the destination, the flight crew received a clearance to conduct a non-directional beacon runway 09 approach at Peterborough Airport. The flight crew did not acquire the runway environment during this approach and conducted a missed approach procedure. During a second approach, the flight crew acquired the runway
