WITNESSES REPORTED SEEING THE AIRPLANE ENTER A CLIMBING 60 DEGREE BANK TURN AFTER TAKEOFF. THEY STATED THE AIRPLANE APPEARED TO STALL DURING THE TURN AND DESCEND TO IMPACT WITH THE HANGAR. THE WITNESSES ALSO STATED THE ENGINE SOUNDED TO BE AT 'CLIMB POWER' OR 'FULL POWER' DURING THE ENTIRE ACCIDENT SEQUENCE. POST ACCIDENT INSPECTION AND TEARDOWN OF THE ENGINE FAILED TO DISCLOSE ANY PREIMPACT FAILURE/MALFUNCTION. ## Factual narrative On April 1, 1994, at 1253 central standard time, a Piper PA-36- 300, N3735E, registered to Carlson Aerial, Inc., collided with the terrain during the initial takeoff climb from runway 17 at the Beloit Municipal Airport, Beloit, Kansas, while on a personal flight. Visual meteorological conditions prevailed and no flight plan was filed. The pilot was seriously injured and the airplane was substantially damaged. The flight was originating at the time of the accident. The pilot reported that at an altitude of 150 feet a loss of engine power was experienced. He continued to report, "The loss of power resulted in a stalled condition with insufficient altitude to recover." The airplane descended into the roof of a hangar. One witness who saw the airplane takeoff stated it made a 60 degree bank, climbing right turn after takeoff to an altitude of about 300 feet. According to this witness the airplane appeared to stall. This witness stated, "Sounded like climb power at all times." Another witness who recounted a similar accident scenario stated, "Sounded like full power on engine." The Federal Aviation Administration (FAA) Inspector who traveled to the accident site reported slash marks were present in the hangar. The aircraft wreckage was moved to Lubbock, Texas, and a teardown was performed which was overseen by an inspector from the Lubbock, Texas, Flight Standards District Office of the FAA. This inspector reported there was no indication of any internal failure of the engine. The fuel control unit was removed and sent to Allied Signal in Canada for testing. The fuel pump was forwarded to Pratt & Whitney in Canada for testing. The fuel control unit was bench tested and was found to perform "within the acceptable test limits." The fuel pump could not be bench tested due to impact damage. A teardown of the pump disclosed, "The pump element itself was found to be in a satisfactory condition." The teardown of the fuel pump and the bench testing to the fuel control unit were overseen by an inspector from Transport Canada. See attached report for further details. ## Aircraft - Registration: [N3735E](https://openairdocs.org/deregistered/N3735E-1995-06-02), registration cancelled 1995-06-02, S/N 367960059 (OpenAirDocs) - Reported make and model: PIPER PA-36-300 - Registry model: [Piper PA-36-300](https://openairdocs.org/model/piper-pa-36-300) (registry code 7103612) (OpenAirDocs) - Category: Airplane - Serial number: 36-7960059 - Airframe hours: 2200 - Engines: P&W PT6A-6 570 horsepower turbo prop - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Carlson Aerial, Inc. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, March 22, 1994, 5 hours before - Departed: K61 - Destination: HSI, HASTINGS, NE - Airport: K61, Moritz Memorial, runway 17, 3,610 × 60 ft, concrete ## Flight crew As NTSB recorded them.

Stalled during nose high climbing turn on takeoff. Fell into a hanger roof. No anomalies found. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
