What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The incident was caused by the engine losing power. The cause of the power loss is believed to be extreme cold weather, the weather at the time was METAR khyr 22-2153 z auto vrb 05 kt 10SM M18/M25. The pilot made every effort to correct the rough running engine including the application of carburetor heat, but was unsuccessful to restore full engine power, and landed in a hay field. The hay field being frozen and rough, resulted in the nose gear of the aircraft collapsing upon touchdown. The field observation suggests the aircraft landed on the right main and nose gear first, as the left main settled down the aircraft rolled and skidded for approximately 200 feet before coming to a stop. This investigation is ongoing, as endorsements in the pilot logbooks and the student pilot certificate need to be investigated further. In regards to the airworthiness of the aircraft the engine needs to be inspected by an FAA airworthiness inspector before the airworthiness of the aircraft can be determined. (-23 amendment) an engine investigation conducted on 01/25/2005 determined the left magneto p lead had a repair near the b nut at the shielding, possi bly causing an intermittant electrical short, however there was spark achieved at all lead ends during engine check. The continuity of the carb heat control could not be determined due to the damage after impact. The engine had compression at all cylinders and the spark plugs were found with minimal normal wear. No discrepancies were found in fuel delivery system. The pilot made every effort to correct the rough running engine including the application of carburetor heat, but was unsuccessful to restore full engine power, and landed in a hay field. The pilot and his instructor was counseled on aircraft emergency procedures. These procedures included the usage of checklist, carburetor heat application and the switching of the magneto from both to the left and right position to correct for the rough running engine.
As the FAA filed it
(-23) THE INCIDENT WAS CAUSED BY THE ENGINE LOSING POWER. THE CAUSE OF THE POWER LOSS IS BELIEVED TO BE EXTREME COLD WEATHER, THE WEATHER AT THE TIME WAS METAR KHYR 22-2153 Z AUTO VRB 05 KT 10SM M18/M25. THE PILOT MADE EVERY EFFORT TO CORRECT THE ROUGH RUNNING ENGINE INCLUDING THE APPLICATION OF CARBURETOR HEAT, BUT WAS UNSUCCESSFUL TO RESTORE FULL ENGINE POWER, AND LANDED IN A HAY FIELD. THE HAY FIELD BEING FROZEN AND ROUGH, RESULTED IN THE NOSE GEAR OF THE AIRCRAFT COLLAPSING UPON TOUCHDOWN. THE FIELD OBSERVATION SUGGESTS THE AIRCRAFT LANDED ON THE RIGHT MAIN AND NOSE GEAR FIRST, AS THE LEFT MAIN SETTLED DOWN THE AIRCRAFT ROLLED AND SKIDDED FOR APPROXIMATELY 200 FEET BEFORE COMING TO A STOP. THIS INVESTIGATION IS ONGOING, AS ENDORSEMENTS IN THE PILOT LOGBOOKS AND THE STUDENT PILOT CERTIFICATE NEED TO BE INVESTIGATED FURTHER. IN REGARDS TO THE AIRWORTHINESS OF THE AIRCRAFT THE ENGINE NEEDS TO BE INSPECTED BY AN FAA AIRWORTHINESS INSPECTOR BEFORE THE AIRWORTHINESS OF THE AIRCRAFT CAN BE DETERMINED. (-23 AMENDMENT) AN ENGINE INVESTIGATION CONDUCTED ON 01/25/2005 DETERMINED THE LEFT MAGNETO P LEAD HAD A REPAIR NEAR THE B NUT AT THE SHIELDING, POSSI BLY CAUSING AN INTERMITTANT ELECTRICAL SHORT, HOWEVER THERE WAS SPARK ACHIEVED AT ALL LEAD ENDS DURING ENGINE CHECK. THE CONTINUITY OF THE CARB HEAT CONTROL COULD NOT BE DETERMINED DUE TO THE DAMAGE AFTER IMPACT. THE ENGINE HAD COMPRESSION AT ALL CYLINDERS AND THE SPARK PLUGS WERE FOUND WITH MINIMAL NORMAL WEAR. NO DISCREPANCIES WERE FOUND IN FUEL DELIVERY SYSTEM. THE PILOT MADE EVERY EFFORT TO CORRECT THE ROUGH RUNNING ENGINE INCLUDING THE APPLICATION OF CARBURETOR HEAT, BUT WAS UNSUCCESSFUL TO RESTORE FULL ENGINE POWER, AND LANDED IN A HAY FIELD. THE PILOT AND HIS INSTRUCTOR WAS COUNSELED ON AIRCRAFT EMERGENCY PROCEDURES. THESE PROCEDURES INCLUDED THE USAGE OF CHECKLIST, CARBURETOR HEAT APPLICATION AND THE SWITCHING OF THE MAGNETO FROM BOTH TO THE LEFT AND RIGHT POSITION TO CORRECT FOR THE ROUGH RUNNING ENGINE.
