## Probable cause

DELAYED GO-AROUND AND STALL ENCOUNTERED. CONTRIBUTING FACTORS WERE A SNOW BANK, PROPER ALIGNMENT NOT ATTAINED, AND RAISING THE FLAPS NOT PERFORMED BY THE PIC.

## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - terrain condition - snowbank (contributing factor)
  - proper alignment - not attained, pilot in command (contributing factor)
  - go-around - delayed, pilot in command (cause)
  - raising of flaps - not performed, pilot in command (contributing factor)
  - stall - encountered, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
- Nose over, other

## Analysis

WHILE ATTEMPTING TO LAND, THE PLT SAID THAT HE DRIFTED TO THE LEFT AND THE GEAR CONTACTED THE BORDERING SNOW. HE ELECTED TO GO-AROUND, BUT WITH FULL FLAPS AND A PAX, THE ACFT STALLED, STRUCK THE TERRAIN AND NOSED OVER.
