Summary
On July 29, 2024, a Raytheon Aircraft Company A36 (N934PC) was involved in an incident near Naples, FL. All 1 person aboard were uninjured. The aircraft sustained substantial damage.
On June 29, 2024, at 1200 Eastern Standard Time, a Raytheon Aircraft A36, N934PC, was substantially damaged during an emergency landing at Naples Municipal Airport (APF), Naples, Florida. The commercial pilot was not injured. The flight was conducted under Title 14 Code of Federal Regulations Part 91 as a personal flight. According to the pilot, after a successful engine run-up, he proceeded to the active runway. He reported that everything was normal during the takeoff roll. However, during the initial climb and the retraction of the landing gear, the engine lost power. He decided to land straight ahead on the runway.
This incident is documented in NTSB report ERA24LA330. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N934PC.

Analysis
On July 29, 2024, at 1210 eastern daylight time, a Raytheon Aircraft Company Bonanza A36, N934PC was substantially damaged when it was involved in an accident at Naples Municipal Airport (APF), Naples, Florida. The pilot was not injured. The flight was conducted under 14 Code of Federal Regulations Part 91 as a personal flight.
The pilot reported that he conducted a preflight inspection, and the engine started and operated normally. The airplane was fueled and taxied to runway 5, where a runup was completed. The magneto check resulted in a 75 rpm drop on each magneto, and all other engine indications were normal. During the takeoff roll, engine indications remained normal. After liftoff, at approximately 150 ft above ground level, the engine began to run rough and (partially) lost power. The pilot lowered the nose and landed straight ahead on the remaining runway with the landing gear retracted. The airplane sustained buckling damage to the fuselage and wing root area.
Postaccident examination of the engine revealed that the crankshaft rotated freely with compression obtained on all six cylinders. Both magnetos produced spark and were correctly timed. The spark plugs displayed normal wear, except for slight oil residue on the Nos. 2 and 4 lower plugs. The gascolator and fuel servo screens were free of debris.
The fuel injectors were removed and examined. The No. 3 injector exhibited evidence of partial obstruction. After cleaning and reinstallation of all injectors, a fuel flow test revealed low flow from the No. 3 injector at high power and from the No. 5 injector at low power. The injectors were removed again for further examination, at which time the No. 2 injector was found to be nearly fully obstructed with debris. A subsequent fuel flow test with the injectors removed revealed normal fuel flow from all injector lines. Fuel samples from both main tanks were clear, light blue, and free of debris. No evidence of internal mechanical failure or ignition malfunction was identified.
A review of the airplane’s maintenance records revealed that the fuel flow transducer was replaced on March 7, 2024. The records further indicated that the fuel injection system was cleaned on July 27, 2024, two days before the accident flight.
