From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On 14 may 2012, aircraft N7199T, owned by gothenburg leasing LLC, was involved in an accident at approximately 1550 hrs. The aircraft made an off-airport landing approximately 2 miles west and 6 miles north of Elm Creek, NE. Location of accident was reported to the FAA by dawson county sheriff's dept. The pilot of the aircraft, privacy data omitted, suffered a broken right ankle as a result of accident. The aircraft was being flown from central city, NE, airport (07K) to the gothenburg, NE, airport after a condition inspection was performed 15 may 2012: the pilot stated that, during level cruise flight of 5000 MSL, and .8 to .9 tenths of an hour into the flight, the engine stopped. He lost approximately 500FT in altitude when he was able to restart the engine by engaging the starter. The engine ran long enough for him to climb back to the 5000 MSL altitude. The engine then stopped a second time and he was able to restart. After the second restart, the engine did not run long enough to regain the lost altitude. The engine repeated this same scenario of starting and stopping a total of 5 times. privacy data omitted Then attempted to land the aircraft in a field, but fell short, and impacted the bank of a minimum maintenance road. Elevation in the area is approximately 2400 ft., and privacy data omitted had less than 500FT of altitude after the engine failed to restart to make a landing. 16 may 2012; inspector craig brumley traveled to lexington, NE, to examine the aircraft. Nathan masten, airport manager, lexington, assisted in examination of the aircraft. The engine exhaust system was removed to allow viewing of the engine cylinders. The engine front was severely scored and shows signs of overheating. The injection oil reservoir that contains the 2 cycle oil was found empty and only a small quantity of oil remained in the lower right hand corner of the tank. The quantity of oil remaining in the reservoir would have been unusable oil to the injection oil system. 13 June 2012: engine tear down was completed by Rotax technical representative, jordan peskevich, in the presence of FAA inspector, craig brumley. Mr. Peskevich examined the engine for fuel, oil and cooling system inconsistencies where deviations from the manufacturer's recommendations for installation were not followed during the engine's installation and maintenance. No installation inconsistencies or engine maintenance issues were noted that would have contributed to the engine seizures by the Rotax engine representative. It was established during the tear down inspection that no leakage from the injection oil reservoir occured post accident. The damage to the cylinder bores and pistons was confirmed by the engine manufacturer's technical representative to be consistent with lack of lubrication.

As the FAA filed it

ON 14 MAY 2012, AIRCRAFT N7199T, OWNED BY GOTHENBURG LEASING LLC, WAS INVOLVED IN AN ACCIDENT AT APPROXIMATELY 1550 HRS. THE AIRCRAFT MADE AN OFF-AIRPORT LANDING APPROXIMATELY 2 MILES WEST AND 6 MILES NORTH OF ELM CREEK, NE. LOCATION OF ACCIDENT WAS REPORTED TO THE FAA BY DAWSON COUNTY SHERIFF'S DEPT. THE PILOT OF THE AIRCRAFT, ^PRIVACY DATA OMITTED^, SUFFERED A BROKEN RIGHT ANKLE AS A RESULT OF ACCIDENT. THE AIRCRAFT WAS BEING FLOWN FROM CENTRAL CITY, NE, AIRPORT (07K) TO THE GOTHENBURG, NE, AIRPORT AFTER A CONDITION INSPECTION WAS PERFORMED 15 MAY 2012: THE PILOT STATED THAT, DURING LEVEL CRUISE FLIGHT OF 5000 MSL, AND .8 TO .9 TENTHS OF AN HOUR INTO THE FLIGHT, THE ENGINE STOPPED. HE LOST APPROXIMATELY 500FT IN ALTITUDE WHEN HE WAS ABLE TO RESTART THE ENGINE BY ENGAGING THE STARTER. THE ENGINE RAN LONG ENOUGH FOR HIM TO CLIMB BACK TO THE 5000 MSL ALTITUDE. THE ENGINE THEN STOPPED A SECOND TIME AND HE WAS ABLE TO RESTART. AFTER THE SECOND RESTART, THE ENGINE DID NOT RUN LONG ENOUGH TO REGAIN THE LOST ALTITUDE. THE ENGINE REPEATED THIS SAME SCENARIO OF STARTING AND STOPPING A TOTAL OF 5 TIMES. ^PRIVACY DATA OMITTED^ THEN ATTEMPTED TO LAND THE AIRCRAFT IN A FIELD, BUT FELL SHORT, AND IMPACTED THE BANK OF A MINIMUM MAINTENANCE ROAD. ELEVATION IN THE AREA IS APPROXIMATELY 2400 FT., AND ^PRIVACY DATA OMITTED^ HAD LESS THAN 500FT OF ALTITUDE AFTER THE ENGINE FAILED TO RESTART TO MAKE A LANDING. 16 MAY 2012; INSPECTOR CRAIG BRUMLEY TRAVELED TO LEXINGTON, NE, TO EXAMINE THE AIRCRAFT. NATHAN MASTEN, AIRPORT MANAGER, LEXINGTON, ASSISTED IN EXAMINATION OF THE AIRCRAFT. THE ENGINE EXHAUST SYSTEM WAS REMOVED TO ALLOW VIEWING OF THE ENGINE CYLINDERS. THE ENGINE FRONT WAS SEVERELY SCORED AND SHOWS SIGNS OF OVERHEATING. THE INJECTION OIL RESERVOIR THAT CONTAINS THE 2 CYCLE OIL WAS FOUND EMPTY AND ONLY A SMALL QUANTITY OF OIL REMAINED IN THE LOWER RIGHT HAND CORNER OF THE TANK. THE QUANTITY OF OIL REMAINING IN THE RESERVOIR WOULD HAVE BEEN UNUSABLE OIL TO THE INJECTION OIL SYSTEM. 13 JUNE 2012: ENGINE TEAR DOWN WAS COMPLETED BY ROTAX TECHNICAL REPRESENTATIVE, JORDAN PESKEVICH, IN THE PRESENCE OF FAA INSPECTOR, CRAIG BRUMLEY. MR. PESKEVICH EXAMINED THE ENGINE FOR FUEL, OIL AND COOLING SYSTEM INCONSISTENCIES WHERE DEVIATIONS FROM THE MANUFACTURER'S RECOMMENDATIONS FOR INSTALLATION WERE NOT FOLLOWED DURING THE ENGINE'S INSTALLATION AND MAINTENANCE. NO INSTALLATION INCONSISTENCIES OR ENGINE MAINTENANCE ISSUES WERE NOTED THAT WOULD HAVE CONTRIBUTED TO THE ENGINE SEIZURES BY THE ROTAX ENGINE REPRESENTATIVE. IT WAS ESTABLISHED DURING THE TEAR DOWN INSPECTION THAT NO LEAKAGE FROM THE INJECTION OIL RESERVOIR OCCURED POST ACCIDENT. THE DAMAGE TO THE CYLINDER BORES AND PISTONS WAS CONFIRMED BY THE ENGINE MANUFACTURER'S TECHNICAL REPRESENTATIVE TO BE CONSISTENT WITH LACK OF LUBRICATION.
