N680LM

On September 01, 2025 about 1605 eastern standard time, an experimental amateur-built Zenith Zodiac 601 HDS, N680LM, was substantially damaged when it was involved in an accident near Connerton, Florida. The pilot and the passenger received minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot reported that he planned to provide rides to four relatives, each on a separate 15-minute flight with a departure from and return to Pilot Country Airport (X05), Brooksville, Florida. In preparation for these flights, the pilot purchased 3 gallons of 89 octane automotive fuel. After he added the fuel, he estimated the airplane's total fuel to be 9.8 gallons prior to the first flight. Before the passengers arrived, the pilot performed a preflight inspection of the airplane and did not notice any abnormalities. On the first two flights, the pilot noted normal engine performance, including normal temperature and pressure readings. The first flight’s duration was 16 minutes, while the second was 12 minutes.

The pilot estimated that the total fuel onboard for the accident flight was 6 to 7 gallons. The pilot stated that the airplane’s cruise fuel consumption was 3.8 to 4.0 gallons per hour (gph), and that the 4 gallons of fuel was sufficient for the upcoming 15-minute flight. The pilot departed on the third flight at 1601. He did not notice anything abnormal during the ground roll or with the initial climb rate. About 420 ft above ground level (agl), the pilot reported “the engine suddenly stopped without any warning.” He further explained there were “no abnormal noises, vibrations or power deviations” prior to the loss of engine power.

He then adjusted the airplane’s pitch attitude for best glide speed, turned into the wind and prepared for an off-field landing. The pilot attempted to restart the engine twice but was unsuccessful, though he did note that the starter was functioning during these attempts. He then performed a forced landing in a nearby field. During the landing sequence, the airplane nosed over and came to rest inverted. The pilot was able to self-extricate, then helped his passenger through the airplane’s shattered canopy.

A Federal Aviation Administration Inspector examined the wreckage at the scene of the accident and observed substantial damage to both wings, the fuselage and rudder of the airplane. Fuel was found in both wing tanks and the fuselage-mounted tank. The header tank was not examined.

The wreckage was recovered and retained for further examination.
