Piper PA-25-235 N7408Z accident near Jacksonville, Florida

Probable cause

The pilot's in-flight loss of control during climb after a banner pickup. Contributing to the accident was the pilot's impairment due to marijuana.

NTSB analysis

The flight was climbing out after picking up a banner. A security camera video showed the airplane climbing with the banner trailing behind before it disappeared from the camera’s view. Shortly after, witnesses observed the banner free falling to the ground and the airplane in a right spin before it impacted a parking lot in a nose-down attitude. Postaccident examination revealed no malfunctions or abnormalities that would have precluded normal operation of the airplane. The levels of Tetrahydrocannabinol (THC, also known as marijuana) and the Tetrahydrocannabinol Carboxylic Acid (THC metabolite) detected in the pilot’s blood during toxicological testing indicated that he had recently used THC. Although the investigation could not determine precisely when the pilot had last used THC, the levels detected indicated that the pilot was impaired and most likely posed a hazard to flight safety. Autopsy results also identified preexisting moderate-to-severe cardiomyopathy; however, there is no indication that this heart condition contributed to the accident.
