## Sequence of events

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

  - door,exterior crew - unlocked (contributing factor)
  - checklist - inadequate, pilot in command (cause)

## Analysis

THE ACFT CRASHED SHORTLY AFTER TAKEOFF IN IMC WEATHER. INVESTIGATION REVEALED THAT FOLLOWING A DISTRACTION FROM A CABIN DOOR BEING LEFT AJAR, COUPLED WITH SOLID IFR FLIGHT CONDITIONS, RESULTED IN THE ACFT ENTERING A STALL PROFILE. THE PLT EXECUTED A FORCED LANDING INTO AN OPEN FIELD. EXAMINATION OF THE ACFT AND ENGINE FAILED TO REVEAL ANY PRE-IMPACT MALFUNCTION OR FAILURE.
