The pilot aborted the takeoff, landed beyond the departure end of the runway, and impacted a building. The airplane sustained substantial damage to the firewall and fuselage. A post-accident inspection by Federal Aviation Administration (FAA) Aviation Safety Inspectors (ASI) revealed that the carburetor was disconnected, however post impact or pre-impact separation of the carburetor could not be determined. ## Factual narrative The pilot of the short takeoff and landing airplane reported that during takeoff, the airplane's engine was producing normal rpm, and "the aircraft lifted off about halfway down the runway but did not climb normally."
