## Sequence of events

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

- Loss of control - in flight, cruise - normal
  - aircraft control - not maintained, pilot in command (cause)
  - altitude - not maintained, pilot in command (cause)
  - fatigue(flight and ground schedule), pilot in command (contributing factor)
  - light condition - dark night
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT HAD COMPLETED HIS NORMAL FLIGHT SCHEDULE AND WAS ASSIGNED AN ADDITIONAL TRIP FROM DES MOINES, IOWA TO ST PAUL, MINNESOTA. CALCULATIONS SHOW THAT THE PILOT HAD FLOWN AN ESTIMATED 5 HOURS IN THE 8 1/2 HOURS PRECEDING THE ACCIDENT. THE LINE ATTENDANT AT ST. PAUL STATED THAT THE PILOT APPEARED TIRED UPON ARRIVAL. THE IMPACT ANGLE AT THE ACCIDENT SITE SUGGESTED AN UNCONTROLLED DESCENT TO THE GND.
