At approximately 11:20 PST, a Piper PA-18-150 clipped a power line during an emergency landing on the Crowley Ranch. The pilot suffered minor injuries. The pilot said he heard a loud pop and a fire started in the aircraft. The pilot elected to make an emergency landing in a nearby field, but clipped a power line while on final approach. This resulted in the aircraft landing hard and both main gear collapsing. After the pilot exited the aircraft, it was almost completely consumed by fire. The pilot reported that the aircrafts alternator had not been charging the battery for a couple of months and that he had taken it to a couple of shops that had not been able to solve the problem.
