## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) PILOT RECEIVED CLEARANCE FOR DEPARTURE AND STARTED TRANSITIONING TO LONE MOUNTAIN. AS THE PILOT LEFT THE CLASS D AIRSPACE, AT APPROXIMATELY ONE MILE TO THE NORTHEAST OF LONE MOUNTAIN AT APPROXIMATELY 3,600 MSL. CO-PILOT ANNOUNCED A SIMULATED ENGINE FAILURE (WHICH THEY DISCUSSED ON THE GROUND). PILOT WOULDN'T DESCRIBE IT AS A THROTTLE CHOOP, BUT MORE LIKE A ROLL OFF. NONETHELESS WHILE PILOT ENTERED AUTOROTATION HE RECOGNIZED IMMEDIATELY THAT THE ENGINE HAD QUIT. PILOT THEN ESTABLISHED HIS AUTOROTATIVE GLIDE AND CONFIRMED WITH THE OIL PRESSURE GAUGE, THE ENGINE TACHOMETER AND THROTTLE MANIPULATION THAT THE ENGINE WAS NOT OPERATIVE. PILOT THEN BEGAN TURNING 180 DEGREES TO THE RIGHT TO FIND AN APPROPRIATE LANDING AREA. AT THE SAME TIME PILOT ATTEMPTED AN AIR RESTART (WHICH WAS UNSUCCESSFUL), AND SWITCHED TO KVGT TOWER FREQUENCY AND ANNOUNCED A MAY DAY CALL. APPROXIMATELY 15-20 SECONDS LATER PILOT DID A FULL DOWN AUTOROTATION TO THE SHOULDER OF A RESIDENTIAL STREET. THE LANDING WAS SUCCESSFUL, CAUSING NO HARM TO PERSONS, PROPERTY OR THE AIRCRAFT.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
