This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed.
On May 20, 2011, at 1513 central daylight time, N8957D, a Piper PA-22 airplane, was destroyed after the pilot made a forced landing to a field due to an in-flight fire. The airplane continued to burn on the ground and was consumed by fire. The private pilot was seriously injured and the passenger was not injured. The airplane was owned and operated by the pilot. Visual meteorological conditions prevailed and no flight plan was filed for the local flight conducted under 14 CFR Part 91
According to the pilot, about 20 minutes after he departed he was maneuvering at an altitude of 600 feet when he began to feel his feet getting hot. He thought it might have been the cabin heat, but the heat was getting more intense and the cockpit began to fill with a gray/bluish colored smoke. The pilot then observed black smoke near his left foot and flames, which he attempted to try and stomp out. The pilot made a forced landing to a muddy field where he and his passenger were able to exit the airplane before it was rapidly consumed by fire.
The airplane was examined by an inspector with the Federal Aviation Administration(FAA)the day after the accident. He stated that the entire fuselage, tail section, right wing and the inboard section of the left wing were consumed by fire. The engine compartment also sustained extensive fire damage.

I sat through a ground school once on an older airplane, the subject of a wing fire came up. 6 minutes is all you have to get on the ground if you can't get the fire out. After that the spar could fail at any time. Unless you are crop dusting that means something around, or in excess of, 1000 FPM at most light aircraft cruising altitudes. The above accident was only at 600 ft. and not a wing fire but it sounds like he is lucky to be alive.
