THE PILOT MADE NO STATEMENT REGARDING THE ACCIDENT CIRCUMSTANCES. GROUND WITNESSES REPORTED HEARING AND OBSERVING THE AIRCRAFT DESCEND INTO A RESIDENTIAL AREA WITHOUT ANY APPARENT ENGINE POWER.

THE CARBURETOR HEAT SYSTEM CONSISTED OF PVC PLUMBING PIPE HELD TOGETHER AND SECURED TO BOTH THE ENGINE EXHAUST SYSTEM AND THE CARBURETOR WITH RTV SEALANT. THE FAA INSPECTORS REPORTED THAT THE EXAMINATION OF THE REVMASTER VW ENGINE ITSELF REVEALED NO EVIDENCE OF A MECHANICAL MALFUNCTION.
