## Probable cause

the pilot's failure to maintain directional control during landing.  A factor was the crosswind.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - weather condition - crosswind (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command
- Gear collapsed, landing - roll
  - landing gear,main gear - overload

## Analysis

The airplane landed on runway 34.  The pilot said the wind was from 070 degrees at 7 knots.  During rollout the airplane yawed to the right, exited the runway, and the left main landing gear collapsed.  The pilot said he was unable to arrest the ground loop.

## Factual narrative

On October 2, 1997, at 1520 central daylight time, a Cessna A185F, N105NR, received substantial damage during a ground loop on landing at Roseau Municipal Airport, near Roseau, Minnesota.  The commercial pilot and two passengers reported no injuries.  The public use flight was for the purpose of surveying migratory waterfowl.  The flight departed Bimidji at 1300, with a planned intermediate stop at Roseau for fuel.  The final leg of the flight was a planned return to Bimidji.  The flight was conducted in visual meteorological conditions.  No flight plan was on file.

The pilot stated that the wind was from 070 at 7 knots.  He landed the airplane on runway 34 (4400' x 75' dry asphalt).  He said after landing he was unable to arrest a "right yaw" which continued through a ground loop when the airplane exited the runway and the left main landing gear collapsed.
