LAX97LA279

The pilot reported that the aircraft had a partial power loss at 1,500 feet msl during the takeoff initial climb, followed by a complete loss of power approximately 2 minutes later. At the time of partial power loss, the pilot applied carburetor heat, turned on the electric fuel pump, switched from the left to the right fuel tank, and checked the position of the magneto switch. Following total loss of power, the pilot made a forced landing on a city street which resulted in substantial damage to the aircraft and minor damage to three parked cars and a bus stop passenger bench. During the onsite investigation, both fuel tanks were found to contain 100LL aviation fuel, and fuel continuity was established between the fuel tanks and the engine carburetor. After transport to a local hanger, the engine was placed on a test stand where it started and ran normally with no apparent malfunctions.

The pilot stated in his report that the aircraft had a partial power loss at 1,500 feet msl during climbout, followed by a complete loss of power approximately 2 minutes later. At the time of partial power loss, the pilot applied carburetor heat, turned on the electric fuel pump, switched from the left to the right fuel tank, and checked the position of the magneto switch. Following total loss of power, the pilot stated that he made a forced landing on a city street which resulted in substantial damage to the aircraft and minor damage to three parked cars and a bus stop passenger bench.

During the on-site investigation by Federal Aviation Administration inspectors, both fuel tanks were found to contain 100LL aviation fuel, and fuel continuity was established between the fuel tanks and the engine carburetor. After transport to a local hanger, the engine was placed on a test stand where it started and ran normally with no apparent malfunctions. The magneto internal and external timing was then checked and found within the tolerance specified by the manufacturer and there was a spark across the gap of each sparkplug. According to the sparkplug color chart supplied by the engine manufacturer, plug color indicated that the engine had been running with a slightly rich mixture.
