NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

During a dual instructional flight, the pilots observed smoke coming from an area behind the instrument panel. The flight instructor (CFI) took control of the aircraft, while they performed the emergency procedure for in-flight fire. The smoke cleared and the instructor gave control back to the owner/pilot. As they were approaching the airport with gear and flaps extended, they attempted to add power to reach the airport. The engine failed to respond, and a forced landing was performed short of the airport. During the forced landing on unprepared terrain, the aircraft was damaged. The aircraft had flown 2.5 hours since the last annual inspection. Postaccident examination revealed three loose injector lines for the left side cylinders. Fuel dye and fire damage was evident on the left side, where the ignition wires were burnt and the cowling was distorted. All fuel injectors had been removed for cleaning and reinstallation with new seals. After the annual inspection, the aircraft had been taken to another shop to repair an engine baffle on the left side. The aircraft had been flown 1.8 hours since repair of the engine baffle.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

failure of a maintenance technician to properly torque the fuel injector lines to three cylinders.
