Event Summary
An aircraft executing a balked landing at a high density altitude airport lifted off when the pilot, feeling he did not have positive control, moved the flap selector to the full up position. He almost immediately decided to move the flap lever back to a 30-degree position, but before he could do so, the aircraft stalled and impacted the runway.
Sequence of Events
The pilot had just lifted off while performing a balked landing. He moved the flap selector to full up because he felt he did not have positive control of the aircraft. He then almost immediately decided to return the flap lever to a 30-degree position. However, before he was able to reposition the lever, the aircraft stalled and struck the runway.
Contributing Circumstances
At about the same time the pilot was attempting to reposition the flap lever, the passenger pulled back on the yoke, which exacerbated the situation.
Conclusion
The events leading to the stall and impact involved a high density altitude airport, a balked landing, flap retraction to full up, and a passenger interaction with the flight controls. No further details are available from the source.
