## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, go-around (vfr)
  - engine assembly - undetermined (contributing factor)
- In flight collision with object, descent - emergency
  - object - ditch (contributing factor)
  - in-flight planning/decision - improper, pilot in command (cause)
- In flight collision with terrain/water, landing - flare/touchdown

## Analysis

WHILE ON A COMBINATION COMPANY BUSINESS AND TRAINING FLIGHT, THE INSTRUCTOR SEATED IN THE RIGHT SEAT OF THE AIRCRAFT COMMANDED THE OTHER PILOT TO EXECUTE A VFR GO-AROUND ON SHORT FINAL. THE OTHER PILOT ADDED POWER TO BOTH ENGINES AND NOTED THAT THE RIGHT ENGINE FAILED TO RESPOND. HE THEN RETARDED BOTH THROTTLES AND THE AIRCRAFT VEERED RIGHT OFF THE RUNWAY. DURING THE LANDING ON THE GRASS THE AIRCRAFT STRUCK A DITCH. EXAMINATION OF THE RIGHT ENGINE AFTER THE ACCIDENT REVEALED NO MECHANICAL MALFUNCTION/FAILURE.
