Accident Overview
While maneuvering during an aerial application flight, the airplane pitched up into a nose-high, "almost vertical" attitude, stalled, and subsequently impacted the terrain. The event was observed by a witness who stated, "the airplane was executing maneuvers like that of an air show, when the pilot pulls [the airplane] straight up and comes straight down."
Aircraft Condition
Examination of the airframe and systems revealed no anomalies that would have precluded normal operation prior to impact. The airplane was otherwise considered airworthy and functioning properly at the time of the accident.
Maneuver Description
The witness description indicates the pilot performed a maneuver where the aircraft pitched up abruptly, reaching a nearly vertical nose-high attitude before stalling. The airplane then descended and struck the ground. The specific type of agricultural operation or chemical being applied was not detailed in the available information.
Investigation Notes
The investigation concluded that the aircraft was operating without any mechanical or system failures that could explain the loss of control. The pilot's actions during the maneuver, as described by the witness, are the primary focus of the factual record. No further analysis or causal determination is provided in the source material.
