What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) After pilot dropped banner aircraft hit trees and crashed. Unable to determine correction action because no interview of pilot could be completed due to the injuries sustained in accident. (-23 amendment) during a banner drop the pilot performed a reduction of power so as to start a descent to a predetermined spot and altitude above the field. When he reached that spot he added full power and the engine did not respond to full power. At this time he dropped the banner, but the aircraft was not producing enough power to sustain level flight. The aircraft descended to a point where the right wing struck branches of a tree and spun the aircraft to the right where it impacted the ground in a vertical position. The aircraft caught fire shortly after and was destroyed. I discussed the procedures for dropping banners and whether he used carburetor heat. He could not be sure that he had done so.
