NTSB narrative
The airplane sustained substantial damage on contact with terrain during a forced landing after a loss of engine power on takeoff. The pilot and passenger sustained minor injuries. The pilot stated, 'I was departing to the east. I climed to about 200 ft. when the engine stoped I turned back for a field. I hit the field and the plane overturned.' The field was rough and uneven. The airplane sustained substantial damage to the hull, wing tips, and tail. The engines fuel filter was found clogged with silicone used as a fuel tank sealant. The plugged filter was a sintered bronze filter. The Rotax installation manual states, 'A suitable fuel filter of 0.15 mm mesh size must be fitted between pump and carburetor. Do not use paper filters. The fuel tank must have a drain cock for condensed water. A screen of 0.3 mm mesh size should be fitted to the fuel line in the tank.' The pilot's safety recommendation was, 'Don't use silicone to seal any type of fuel tanks or exc.'
Probable cause
the obstructed fuel system filter, the inadequate silicone material the builder used, and the rough and uneven terrain. A factor was that suitable landing terrain was not available.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
