NTSB narrative
The pilot reported that shortly after liftoff during a minimum unstick speed flight test, a 'maximum angle of attack overshoot occurred.' The pilot stated that during the recovery process, the aircraft touched down and veered to the left. The pilot corrected with a right bank. During the banking turn, the right wingtip and aileron dragged on the runway surface and the left main landing gear struck two runway edge lighting signs. The aircraft became airborne again at a lower angle of attack and continued to climb. The aircraft then returned for landing without further incident. During the recovery maneuver, an emergency vehicle that was positioned near the runway and supporting the flight test, took evasive action to avoid a collision when the aircraft came within 50 feet of its position.
Probable cause
Aircraft control was not maintained.

Source notes (4)
- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1998-07-30.
