Circumstances:
Shortly after takeoff, the pilot smelled smoke. As he began to turn the airplane back to the airport, the engine lost total power. He conducted a forced landing in a field just short of the airport, during which the airplane struck a metal fence and pipe. All occupants egressed, and the pilot then noticed that a fire had erupted under the airplane's engine cowling. Postaccident examination revealed that the airplane sustained fire damage to the roof and forward end of the baggage compartment along with the engine accessory area between the firewall and aft air baffles. Further examination revealed that one of the engine exhaust crossover pipe assemblies was misaligned at the slip joint. An engine manufacturer service bulletin (SB) called for inspections of the exhaust system slip and flange joints to identify misaligned exhaust components. The last maintenance event occurred about 7 1/2 flight hours before the accident, during which the SB was performed and resulted in the replacement of crossover pipes. The mechanic who had performed the most recent maintenance did not follow the correct procedures for reinstallation of the crossover pipe, and the inspector who reviewed his work did not examine the installation as it progressed but instead inspected the pipes after they were installed and essentially hidden from view by their protective heat shield. As a result of the misaligned engine exhaust crossover pipe, hot exhaust gases escaped into the engine compartment and started a fire, which compromised critical engine fuel and oil lines, and resulted in the loss of engine power.
Probable cause:
The mechanic's failure to properly align the engine exhaust crossover pipe during replacement, and his supervisor's failure to properly inspect the installation, which resulted in an in-flight fire and the loss of engine power.

Circumstances:
According to the pilot, about 15 minutes before reaching the destination airport during descent, the engine lost power. The pilot switched fuel tanks, and the engine power was momentarily restored, but the engine stopped producing power even though he thought it "was still running all the way to impact." The pilot conducted a forced landed on a highway at night, and the right wing struck an object and separated from the airplane. The airplane came to rest inverted. According to the Federal Aviation Administration (FAA) aviation safety inspector (ASI) that performed the postaccident airplane examination, the fuel lines to the fuel manifold were dry, and the fuel manifold valves were dry. He reported that the fuel strainer, the diaphragm, and the fuel filter in the duel manifold were unremarkable. Fuel was found in the gascolator. The FAA ASI reported that, during his interview with the pilot, "the pilot changed his story from fuel exhaustion, to fuel contamination." The inspector reported that there were no signs of fuel contamination during the examination of the fuel system. According to the fixed-base operator (FBO) at the departure airport, the pilot requested 20 gallons of fuel. He then canceled his fuel request and walked out of the FBO.
Probable cause:
The pilot's improper fuel planning, which resulted in fuel exhaustion and the subsequent total loss of engine power.
Final Report:
