Aviation Accident Final Report - National Transportation Safety Board:

Investigation Docket - National Transportation Safety Board: 

Location: Newtok, AK
Accident Number: GAA18CA154
Date & Time: 02/25/2018, 1320 AKS
Registration: N1658U
Aircraft: CESSNA 207
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Positioning 


The pilot reported that during a return flight, he elected to fly from the right pilot seat, to allow a cargo-handler to sit in the left pilot seat. The taxi to the runway was short and required little rudder input. However, during takeoff, as he added power, he "did not seem" to have full right rudder authority and he was unable to maintain the runway centerline. Subsequently, the airplane exited the left side of the runway, struck a small ridge, and came to rest nose down.

The airplane sustained substantial damage to the fuselage and left-wing.

The pilot further reported that, after the accident, he realized the airplane had stow-able rudder pedals on the right side, and that they had been placed in the "stowed" position.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control during takeoff. Contributing to the accident was the pilot's failure to properly check that the flight controls were correctly configured before takeoff. 


Directional control - Attain/maintain not possible (Cause)
Rudder - Inadequate inspection

Personnel issues
Aircraft control - Pilot (Cause)
Lack of action - Pilot (Factor)
