An aircraft stalled and flipped over during a takeoff at a density altitude of 7,011 feet. The pilot, accustomed to sea-level operations, rotated late and raised flaps early, leading to a loss of altitude and stall at 15 feet AGL.

Incident Overview

An aircraft experienced a stall and subsequent ground impact during a takeoff in high-density-altitude conditions. The airplane was approximately 200 pounds below its maximum gross weight for the departure. The pilot reported that all previous takeoffs had been conducted near sea level, and he was not accustomed to operations at elevated density altitudes. The density altitude at the time was 7,011 feet.

Sequence of Events

According to the pilot, the aircraft was rotated about three-quarters of the way down the runway, resulting in a "little nose high attitude." It climbed to approximately 100 feet above ground level (AGL). At that point, the landing gear was retracted and the flaps were raised to 10 degrees. Immediately afterward, the aircraft began to settle back toward the ground. It stalled at an altitude of about 15 feet AGL. The aircraft then struck the ground in a nose-low attitude and flipped onto its back.
