NTSB Factual Report

On October 28, 2016, at 0954 mountain daylight time, a Cirrus Design SR22 airplane, N234PJ, was substantially damaged during a forced landing following a loss of engine power during cruise flight near Bloomfield, New Mexico. The pilot was not injured. The airplane was registered to Coastal King Aviation, LLC, and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The flight originated from the Albuquerque International Airport (ABQ), Albuquerque, New Mexico, at 0903. The intended destination was the Stevens Field Airport (PSO), Pagosa Springs, Colorado.

The pilot reported that shortly after leveling at a cruise altitude of 11,500 feet mean sea level, the engine starting "missing" and within two minutes lost power completely. His attempts to restore engine power were not successful. He was unable to locate a suitable forced landing site within the glide range of the airplane and elected to active the Cirrus Airframe Parachute System. The airplane came to rest in an area of low brush and small trees. The aft fuselage/empennage separated from the airframe during the accident sequence and was located immediately adjacent to the airplane at the accident site.

A post-recovery engine examination was conducted under supervision of the NTSB investigator-in-charge. The engine cowling appeared intact and securely installed. The cowling was removed. The engine assembly appeared intact and undamaged, with one exception. The lower surface of the oil sump pan was dented consistent with contact from the nose landing gear strut on touch down. The propeller assembly remained securely attached to the engine propeller flange and appeared undamaged. The engine crankshaft rotated freely. The upper spark plugs exhibited normal operating signatures. Borescope examination of the cylinders did not reveal any anomalies. The magnetos and ignition harness appeared undamaged. Engine control continuity was confirmed. At the time of the postaccident examination, the recording hour (Hobbs) meter indicated 980.8 hours.

The examination revealed that the cap on the unmetered fuel tee fitting at the throttle body metering unit was not installed. The cap was subsequently recovered from the cylinder baffling immediately below the throttle body metering unit. Both the fitting and the cap appeared to be undamaged. The cap was subsequently reinstalled. A portable fuel supply was provided to the airframe at the left wing root and the engine was run on the airframe. The engine started without difficulty and ran at idle power for several minutes. Engine power was not increased above idle during the test run due to safety considerations.

Data downloaded from the onboard avionics indicated that the flight departed at 0903, and after takeoff, the airplane climbed to about 10,500 ft mean sea level (msl). About 0945, the airplane began a climb, reaching 11,400 ft msl about 2-1/2 minutes later. The engine speed and fuel flow were stable during this timeframe. About 0948:06, the engine speed and fuel flow decayed abruptly, and the airplane entered a gradual descent. The engine speed did not recover for the duration of the recorded data. The fuel flow initially decreased from about 18.0 gph before the event to 9.9 gph, before increasing to about 30.0 gph for a period of time. The recorded data ended at 0954.

A review of the airplane maintenance records revealed that the most recent annual inspection was completed on March 4, 2016, at 951.6 hours airframe total time. On May 19, 2016, at 959.3 hours total airframe time, the engine was removed due to a propeller strike event. [Federal Aviation Administration records revealed that on May 13, 2016, the accident airplane was involved in a propeller strike incident during landing at the Dothan Regional Airport (DHN).] A factory rebuilt engine was subsequently installed on September 7, 2016. A hard/overweight landing inspection was completed with no defects noted. According to the records, the propeller assembly and propeller governor were also overhauled and reinstalled at that time. The maintenance records noted that an engine run-up inspection was completed in accordance with the IO550 Permold Series Engine Installation and Operation Manual, section 3-2.7. The fuel system was adjusted in accordance with the Maintenance and Overhaul Manual (M-16), section 6-3.7 "Engine Operational Check."

Maintenance records indicated that on October 5, 2016, at 959.3 hours airframe total time, the engine manufacturer's fuel nozzles were removed and replaced with General Aviation Modifications Inc. fuel nozzles. On October 12, 2016, at 971.6 hours airframe total time, an operational flight check was completed in accordance with the IO550 Permold Engine Installation and Operation Manual, sections 4-2.3 and 4-2.3.2. In addition, a ground run was conducted in order to verify fuel system settings in accordance with sections 6-3.7.4.2 and 6-3.7.4.3 of the engine maintenance and overhaul manual. The airplane maintenance records contained no subsequent entries.

The Engine Maintenance and Overhaul Manual, section 6-3.7.4.2 Fuel System Operational Checkout with Calibrated Gauges, specified removal of the unmetered fuel port fitting cap at the throttle body metering unit in order to connect an external fuel pressure gauge. The procedure also specified reinstalling the cap once the testing and any necessary fuel system adjustments had been completed.

The Pilot's Operating Handbook indicated that the fuel flow transducer was installed between the fuel pump/mixture control and the throttle body metering unit, which was upstream in the fuel flow relative to the fuel port fitting. The engine driven fuel pump and mixture control are combined into one component.
