During his fourth takeoff from the same strip, an agricultural pilot overboosted the engine to clear trees. The airplane settled into a rice field, hit a levee, and flipped to an inverted position.

Incident Overview

An agricultural pilot reported that during his fourth takeoff attempt from the same airstrip that day, the airplane failed to climb as expected. To avoid trees ahead, he over-boosted the engine, but the aircraft exhibited low airspeed and a high angle of attack, causing it to begin settling.

Sequence of Events

In response to the descent, the pilot dumped the load and lowered the nose. The airplane subsequently descended into a rice field, struck a levee, and nosed over into an inverted position. The pilot did not specify the type of aircraft or registration.

Investigation Findings

Federal Aviation Administration (FAA) investigators noted that during the takeoff, the airplane encountered a wind shift from crosswind to tailwind, which caused it to make contact with small trees. The occurrence was part of the pilot's fourth operation from the same strip that day. No other details regarding injuries, damage, or environmental conditions were provided.
