NTSB narrative
The tow pilot reported that the first flight of the day was to check for convective activity and was uneventful. After a hang glider was hooked up to the airplane, the pilot performed a normal takeoff. During the initial climb, the engine lost total power about 50 ft above ground level and although the pilot immediately lowered the airplane’s nose, he stated that “there was too much drag from the tow line and the airplane stalled and pancaked to the ground.” The hang glider pilot reported that when he noticed slack in the town line, he disconnected, and landed safely. The engine subsequently regained power and the airplane impacted the ground and was substantially damaged during the subsequent ground loop and impact with a parked snowplow. A postaccident examination of the engine revealed that a clamp securing one of the two carburetors was loose, and its anti-vibration spring was found disconnected. This condition may have led to erratic engine performance including sputtering, surging, and loss of power. No other mechanical discrepancies were discovered during the examination. Based on this information, it is likely that the loss of engine power was due to the discrepancies noted with the carburetor.
Probable cause
The improper installation of the carburetor, which resulted in a momentary total loss of engine power during initial climb. Contributing was the pilot’s failure to maintain control of the airplane following the initial power loss.

- 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, cause areas. Values present in the bulk record are kept.
