In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

## Analysis

DURING A SUPERVISED SOLO FLIGHT, THE STUDENT PILOT EXPERIENCED A PARTIAL POWER LOSS. THE STUDENT APPLIED CARBURETOR HEAT, BUT THE ENGINE CONTINUED TO RUN ROUGH. THE STUDENT TURNED TOWARDS THE AIRSTRIP AND ATTEMPTED AN EMGCY LNDG. THE ACFT TOUCHED DOWN AT 2000FT PAST THE THRESHOLD AND RAN OFF THE END OF THE RWY. THE WRECKAGE EXAMINATION DISCLOSED THAT THE RIGHT MAGNETO COIL WAS CRACKED AND THERE WAS CORROSION INSIDE OF THE MAGNETO'S HOUSING. THE LEFT MAGNETO'S INTERNAL POINTS WERE NOT PROPERLY SET.
