摘要

Sport Aircraft a.s. Piper Sport airplane (N422PS) crashed after a loss of engine power at Addison Airport (ADS), Addison, Texas. The flight instructor and passenger sustained serious injuries and the airplane was heavily damaged. The airplane was registered to a private individual and operated by Excite Aircraft, Inc., doing business as US Sport Aircraft under FAR Part 91 as an instructional flight. It was VFR at the time of the accident and no flight plan had been filed. The local flight departed ADS at 1644. A review of the ADS ATC recording revealed that at 1642 the pilot called ATC for a departure clearance while holding short of Runway 15. At 1643, ATC instructed the pilot to line up and wait on Runway 15. At 1644, ATC cleared the airplane for takeoff. At 1646, the pilot stated to ATC "we're having vapor lock, we need to come back and land." There were no further communications from the pilot. Several witnesses observed the accident airplane during the event and reported that the airplane was flying west over the southeast side of the airport. The airplane descended out of view behind several hangars and then climbed above the hangars while flying south. The airplane made a left climbing turn toward the runway and then descended again until it impacted terrain on the east side of Runway 33 threshold. A review of the airport surveillance video revealed that at 1646 the airplane was flying southeast above the end of Runway 15. The airplane descended in a wings level attitude before it made sharp left turn and impacted the ground. The airplane came to rest in the grass between taxiway A and Runway 15/33.
