Probable cause

The pilot's failure to maintain adequate airspeed and his exceedance of the airplane's critical angle of attack during a low pass, which resulted in an aerodynamic stall and impact with terrain.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he was conducting a low-altitude application flight for a gender reveal celebration with one passenger onboard the single-seat airplane. While maneuvering, he dumped about 350 gallons of pink water. The airplane got too slow, aerodynamically stalled, impacted terrain, and then came to rest inverted. The airplane sustained substantial damage to the fuselage, right wing, and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Factual narrative

The pilot reported, that while maneuvering at a low altitude in an aerial applicator airplane, he dumped about 350 gallons of pink water for a gender reveal. The airplane "got too slow", aerodynamically stalled, impacted terrain, and came to rest inverted. The airplane sustained substantial damage to the fuselage, right wing, and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The Federal Aviation Administration inspector reported that the accident occurred during a low pass for a gender reveal celebration. He added that there were two persons on board the single seat airplane.
