Incident Summary
The pilot reported that the engine began to run rough, and he could smell smoke in the cockpit. The smoke worsened, prompting him to shut off the master switch. He sighted the airport and headed toward it, but engine power began to fail.
Landing Attempt
The pilot attempted to land on runway 16, which had a tailwind of 22 knots, gusting to 26 knots. He was too high on approach. To avoid some buildings, he turned right to approximately 180 degrees. He then landed about 1,000 feet from the departure end of the runway in scrub-covered terrain. During the landing, the airplane impacted a berm and nosed over.
Damage and Examination
The accident damaged the airplane's vertical stabilizer, left wing, and fuselage. A postaccident examination of the engine by a mechanic revealed that the turbocharger's oil scavenger pump had failed. The mechanic stated that the scavenger pump's failure would cause the engine's oil to pass overboard.
