1993-04-03: Cessna 170 (N4190V) — Nordgren, Craig D. — Anchorage, AK

Anchorage, AK, US

On April 3, 1993, a Cessna 170 (registration N4190V) operated by Nordgren, Craig D. was involved in an aviation accident near Anchorage, AK. Investigators recorded the probable cause as: THE PILOT IN COMMAND'S PREMATURE LIFT-OFF. CONTRIBUTING FACTORS WERE THE PILOT'S FAILURE TO ABORT THE TAKEOFF, HIS LACK OF TOTAL EXPEREINCE IN THE TYPE AIRPLANE AND TYPE OPERATION, AND THE SLUSH COVERED RUNWAY. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A ski-equipped airplane on a snow-covered runway dragged its tail wheel during takeoff, leading to a late liftoff and collision with trees and a snowbank after passing the runway end.

Accident Overview

A ski-equipped airplane collided with trees and a snowbank after making a downhill takeoff from a runway covered with approximately 12 inches of slushy wet snow. The accident occurred just after the airplane passed the end of the runway, when it descended and impacted terrain.

Pilot and Flight History

The pilot, a private pilot with 57 hours of total flight experience, had recently purchased the airplane. On the day prior to the accident, the pilot flew the airplane for the first time, logging 1.8 hours with a more experienced pilot and friend. That flight was also the pilot's only experience as the pilot of an airplane equipped with skis or with a tail wheel.

Takeoff Sequence

According to the pilot, the airplane's tail wheel—which was not equipped with a ski—dragged in the snow during the takeoff roll. This drag prevented the airplane from becoming airborne sooner. After the pilot succeeded in lifting the tail out of the snow, he attempted to rotate the airplane before it had gained sufficient takeoff airspeed. This rotation caused the tail wheel to re-enter the snow. The airplane eventually became airborne about three-quarters of the way down the runway, then flew in ground effect until it passed over the end of the runway, where the terrain dropped away. Shortly thereafter, the airplane descended and struck trees and a snowbank.
