## Probable cause

The pilot's failure to maintain control of the airplane during the takeoff roll.  Factors were the slick condition of the runway, and the lack of markings to denote the runway safety area.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - aircraft control - not maintained, pilot in command (cause)
  - terrain condition - icy (contributing factor)
- On ground/water collision with object, takeoff - aborted
  - object - vehicle
  - airport facilities,runway safety area - unmarked (contributing factor)

## Analysis

The pilot of the tailwheel airplane aligned the airplane on the ice runway and advanced the throttle for takeoff.  The airplane began to slide left, and the pilot reduced the throttle and applied full right rudder; however, the airplane continued sliding left and impacted a truck parked about 20 feet from the left edge of the runway.  A 125-foot safety area existed around the runway, but there were no markings or signage present to prevent vehicles from encroaching on that area.  When asked how the accident could have been prevented, the pilot wrote, "Due to the extremely slick conditions, slower application of power may have kept [the] aircraft from sliding left."

## Factual narrative

According to the pilot of the Maule MXT-7-180A, he aligned the airplane on the ice runway and advanced the throttle for takeoff.  The airplane began to slide left, so the pilot reduced the throttle and applied full right rudder; however, the airplane continued sliding left and impacted a truck parked about 20 feet from the left edge of the runway.  According to the airport manager, a 125-foot safety area existed around the runway, but there were no markings or signage present to prevent vehicles from encroaching on that area.  When asked how the accident could have been prevented, the pilot stated "Due to the extremely slick conditions, slower application of power may have kept [the] aircraft from sliding left."
