## Analysis

APPROXIMATELY 3 MILES SHORT OF THE DESTINATION ARPT THE PLT STATED THAT THE ENGINE QUIT. THE ACFT WAS LINED UP WITH A ROAD BUT DUE TO HEAVY TRAFFIC THE PLT ELECTED TO STALL THE ACFT INTO NEARBY TREES. EXAMINATION OF THE ACFT BY THE FAA FOLLOWING THE ACCIDENT DISCLOSED THAT THEY COULD NOT FIND ANY FUEL ONBOARD THE ACFT. DURING RETRIEVAL, THE SALVAGE CREW DRAINED 2-3 GALS OUT OF THE RT WING TANK. EXAMINATION OF THE RT WING FUEL CAP VENT DID NOT REVEAL ANY MALFUNCTION.
