## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - electrical system - undetermined (contributing factor)
  - electrical system - overtemperature (contributing factor)
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - snowbank (contributing factor)
  - clearance - misjudged, pilot in command (cause)
  - diverted attention, pilot in command (cause)

## Analysis

THE PLT REPORTED THAT AFTER TAKING OFF, THE CABIN BEGAN TO FILL WITH SMOKE. HE RETURNED TO THE ARPT FOR A PRECAUTIONARY LANDING; HOWEVER, DURING TOUCHDOWN, THE LEFT WING COLLIDED WITH A SNOWBANK BESIDE THE RWY. AN EXAM OF THE ACFT REVEALED THAT WITH THE ENG SHUT DOWN, NO SMOKE WOULD DEVELOPE WHEN THE MASTER SWITCH WAS TURNED ON. HOWEVER, AFTER THE ENG WAS STARTED, SMOKE APPEARED.
