Accident Details
On March 29, 2024, at about 1250 eastern daylight time, a Navion B airplane, registration N5429K, was substantially damaged during an accident near Sanford, Florida. The commercial pilot and one passenger were not injured. The flight was conducted as a personal flight under Title 14 Code of Federal Regulations Part 91.
Pilot's Account
The pilot reported that preflight inspection, engine start, and taxi to runway 27R at Orlando Sanford International Airport (SFB) were normal. After receiving clearance for takeoff, he advanced the throttle to full power, and all engine indications were in the green. Shortly after takeoff, following landing gear retraction, the pilot stated that "everything went silent" and the engine lost all power. The airplane descended back onto the runway, landing hard with the landing gear retracted, and skidded to a stop on the runway surface. The pilot and passenger egressed the airplane and were met by first responders.
Examination and Inspection
A Federal Aviation Administration inspector examined the wreckage at the accident site and confirmed substantial damage to the lower and aft fuselage. After recovery to the owner's hangar, the engine was examined. The fuel tanks contained an adequate supply of fuel. The top spark plugs were removed, and the engine's crankshaft was turned manually using the propeller. Compression and suction were confirmed on all cylinders. Cylinder interiors were examined with a lighted borescope, revealing no anomalies with piston heads, valves, or cylinder walls. The electric fuel pump was energized and pumped normally. The engine-driven fuel pump appeared normal. The right magneto produced spark on all towers when turned; the left magneto could not be tested.
Findings
No preimpact mechanical deficiencies were noted that would have precluded normal operation of the engine and airframe.
