## Narrative

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

PILOT WAS ENROUTE FROM DURANGO, CO. TO NOGALES, AZ. WHEN HE EXPERIENCED A LOSS OF ENGINE POWER. PILOT STATED HE WAS IN CONTACT WITH ALBUQUERQUE CENTER (ZAB) AND WAS CLIMBING FROM 12,000 TO 14,000 FT MSL WHEN HE HEARD A "POP" SOUND FROM THE ENGINE AREA. HE THEN EXPERIENCED A DROP IN MANIFOLD PRESSURE (MP) AND THE ENGINE BEGAN RUNNING ROUGH. HE REACTED BY LEANING THE MIXTURE CONTROL AND REDUCING THE THROTTLE. HE STATED HE THOUGHT HE HAD LOST THE SUPERCHARGER DRIVE BELT AS THIS HAD HAPPENED ONCE BEFORE DURING A FLIGHT. INITIALLY HE WAS NOT CONCERNED ABOUT THE LOSS OF MP AS HE KNEW HE COULD FLY THE AIRCRAFT WITHOUT THE SUPERCHARGER AND IT WOULD SIMPLY GO BACK TO A NORMALLY ASPIRATED CONDITION ONCE THE ENGINE WAS PROPERLY LEANED. HE THEN CONTACTED ZAB TO NOTIFY THEM HE HAD A PROBLEM, BUT THAT IT WAS NOT AN EMERGENCY. HE DISENGAGED THE AUTOPILOT AND CORRECTED HIS CLIMB TO LEVEL OFF AT 14K. A MINUTE OR TWO LATER THE ENGINE MONITOR HAD A BLINKING AMBER LIGHT INDICATING LOW OIL PRESSURE. THE PILOT CHECKED THE OIL PRESSURE AND NOTED OIL PRESSURE WAS 47 LBS AND DECLINING. HE CALLED ZAB AND DECLARED AN EMERGENCY. ZAB GAVE HIM A STEERING FOR SHOW LOW (SOW) WHICH HE TURNED TO AND SET THE AIRSPEED UP FOR BEST GLIDE. ZAB ANNOUNCED THAT HE WAS GETTING READY TO BE LOST ON RADAR BECAUSE OF HIS DECLINING ALTITUDE. AT THAT POINT THE PILOT STATED THAT HE WAS NOT GOING TO BE ABLE TO MAKE THE SOW AIRPORT. HE TOLD ZAB THAT HE WAS GOING TO STEER FOR AN OPEN FIELD AND FIRE HIS PARACHUTE. HE ASKED THEM TO CALL FOR HELP. ONCE THE PARACHUTE WAS POPPED THE PILOT STATED THAT HE WAS UNDER THE CANOPY FOR ABOUT 3 SWINGS WHEN THE AIRCRAFT CONTACTED THE LANDING AREA. DURING THE TIME HE WAS DESCENDING UNDER THE CANOPY THE PILOT STATED THAT HE TURNED THE AIRCRAFT POWER OFF AND OPENED THE CANOPY DOOR IN ANTICIPATION OF THE LANDING. THE LANDING WAS VERY HARD AND KNOCKED THE BREATH OUT OF HIM, BUT HE WAS ABLE TO IMMEDIATELY EGRESS THE AIRCRAFT.THE PILOT WAS TAKEN TO THE HOSPITAL AFTER THE RESCUE AND FOUND THAT HE HAD A FRACTURED VERTEBRA, BUT NO OTHER MEDICAL PROBLEMS.THE AIRCRAFT SUFFERED SUBSTANTIAL DAMAGE WHEN IT CONTACTED THE GROUND UNDER CANOPY. THE LANDING GEAR WAS TORN FROM THE AIRCRAFT. INVESTIGATION OF THE AIRCRAFT AT THE SCENE DETERMINED THAT THERE WAS OIL RESIDUE FROM THE ENGINE COMPARTMENT DOWN THE LEFT HAND SIDE OF THE AIRCRAFT AND BELLY. ONCE THE ENGINE COWLING WAS REMOVED IT WAS APPARENT THAT THE OIL LINE FITTING TO THE SUPERCHARGER HAD FAILED AND ALLOWED ENGINE OIL TO BE PUMPED OVERBOARD.NTSB, FAA, ENGINE, AND AIRFRAME MANUFACTURERS ARE CURRENTLY CONDUCTING FURTHER INVESTIGATION OF THE ENGINE AND ITS COMPONENTS.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB WPR13LA043](https://openairdocs.org/ntsb/WPR13LA043), Nov 16, 2012: Cirrus SR22 (N800RW), Show Low, AZ, substantial damage. Probable cause: The fatigue failure of an improperly installed nipple in the oil system of a supplemental type certificate-installed supercharger, which resulted in a complete loss of engine oil during cruise climb.

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.
