Narrative:
On September 19, 1998, at 1314 mountain daylight time, a Piper PA-20-180, N6028D, was destroyed during an emergency landing following a loss of power. The aircraft impacted in a field adjacent to a residential area in Thornton, Colorado. The commercial pilot sustained serious injuries. The flight was a banner tow operating under Title 14 CFR Part 91 and no flight plan was filed. Visual meteorological conditions prevailed. The flight originated from Aurora Air Park, Watkins, Colorado, at 1300.
According to the pilot, about 14 minutes after departure while in cruise flight at 1,200 feet above ground level (agl), the engine made a loud bang, seized, and it appeared that the engine moved to the right and part of the cowling came loose.
In an interview, the pilot said that following the failure, he had limited aileron control but no pitch or yaw control. He said he guided the aircraft to an open field in a residential area.
Witness marks at the crash site provided evidence the aircraft struck trees beside a house located at the top of a hill above where the aircraft came to rest. After striking the trees, the aircraft impacted the ground in an inverted attitude and skidded to a stop. There was no fire and the pilot was removed from the aircraft by emergency response personnel and transported to medical facilities.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The separation of a propeller blade due to corrosion initiated fatigue, followed by the separation of several of the engine's mounts, and the subsequent inability of the pilot to control the aircraft. A contributing factor was the trees.
