- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Initial climb
- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

NTSB narrative
The pilot and three passengers were departing on a cross-country flight from a turf runway. The pilot stated that he used a soft-field takeoff technique, and once the airplane became airborne in ground effect, it did not accelerate as expected. The engine was producing power; however, there was a lack of acceleration and a “mushy” feeling. The airspeed continued to decrease, and the pilot banked the airplane left to make an emergency landing off the left side of the runway. The pilot heard the airplane’s stall warning horn, and the airplane collided with small trees and came to rest upright.
A postaccident test run of the engine revealed no anomalies that would have prevented normal operation or production of rated power.
Data from an engine data monitor revealed that, during the accident takeoff, the engine speed reached about 2,700 rpm, the engine manifold pressure was 35.2 inches of mercury (inHg), and the fuel flow reached 40.5 gallons per hour (gph). A review of the previous three flights showed that the fuel flow regularly reached 38 to 40 gph during takeoff. The airplane flight manual stated that at 2,700 rpm and 36.0 inHg, the maximum fuel flow was 34.2 gph. The reason for this difference was not determined.
Probable cause
A lack of climb performance after takeoff for reasons that could not be determined based on the available information.

Source notes (5)
- 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.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 17532ee44cc11f2a535563927c17678c8320ea5237b2381f0d3cd5ebf023a57c; retrieved 2026-09-16T10:18:03.949Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: destination. T67 is Hicks Airfield at Fort Worth, TX; 'Forth Worth' is a misspelling.
