- History of Flight:
On November 8, 2025, at about 1040 local time, an Extra EA 300/SC, N330SL, registered to Avtech Group LLC out of St. Augustine, FL, was destroyed when it was involved in an accident at Keystone Heights Airport (42J), Keystone Heights, Florida. The sole pilot onboard sustained fatal injuries. The local flight originated from 42J.
Preliminary information indicates the airplane was conducting aerobatic manoeuvres when it entered an inverted spin and lost control.
Preliminary ADS-B data shows that the airplane was flying over the airport at 3,700 ft when it entered a sudden descent to 1,000 ft and disappeared from coverage.
- Pilot Information:
unknown at this point.
- Airplane Information:
The accident aircraft, serial number SC050, was manufactured in 2014. It was a single-seat, low-wing aerobatic monoplane powered by a Lycoming IO-580-X engine rated at 320 hp.
According to the Pilot Operating Handbook (POH):
The plane is designed for acrobatics. Inverted flight maneuvers are limited to max 4 min.
According to section 4.12.3, SPIN:
To enter a spin proceed as follows:
- Reduce speed, power idle
- When the plane stalls:
- kick rudder to desired spin direction
- hold ailerons neutral
- stick back (positive spinning), Stick forward (negative spinning)
The plane will immediately enter a stable spin.
- Ailerons against spin direction will make the spin flatter.
- Ailerons into spin direction will lead to a spiral dive.
Above apply for positive and negative spinning.
To stop the spin:
- Apply opposite rudder
- Make sure, power idle
- Hold ailerons neutral
- Stick to neutral position
After six turns of spinning the plane will recover within about 1 turn.
Recovery can still be improved by feeding in in-spin ailerons.
N O T E
If ever disorientation should occur during spins (normal or inverted) one method always works to stop the spin:
- Power idle
- Kick rudder to the heavier side (this will always be against spin direction)
- Take hands off the stick The spin will end after 1/2 thru 1 turn.
The plane will be in a steep dive in a side-slip. Recovery to normal flight can be performed easily.
N O T E
After one turn of spinning the altitude loss including recovery is within about 1500 ft.
After six turns of spinning the altitude loss including recovery is within about 3300 ft.
- Wreckage and Impact Information:
The airplane impacted open flat terrain, came to rest inverted and was consumed by a post crash fire. The main wreckage consisted of the entire airplane, which was confined within one area without a notable debris field. Both wings and tail remained attached to the airframe. It appears that both propeller blades remained attached to the propeller hub, which was still attached to the engine. The impact appears consistent with an inverted flight profile with little to no forward airspeed.
- Airport Information:
Keystone Heights Airport is a non-towered public airport located about 3 miles north of Keystone Heights, Florida. The airport field elevation was 196 ft. The airport features two asphalt runways, runway 5/23 (5046x100 ft) and runway 11/29 (4899x75 ft).
- Weather:
The reported weather at 1035: Winds 180 at 5 knots, visbility 9 miles, a broken cloud layer at 8500 ft, temparture 25°C, dewpoint 19°C, and an altimeter setting of 29.95 inches of mercury
