1992-04-28: Cessna 140 (N77205) — H.t. Fancher — Grain Valley, MO

Grain Valley, MO, US

On April 28, 1992, a Cessna 140 (registration N77205) operated by H.t. Fancher was involved in an aviation accident near Grain Valley, MO. Investigators recorded the probable cause as: The pilot's failure to maintain aircraft control during the initial climb, which resulted in a stall, due to his decision to take off downwind at an unfamiliar airport where he had become disoriented. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot became disoriented while taxiing at an unfamiliar airport and attempted a downwind takeoff. After realizing the aircraft could not clear obstacles, a left turn was initiated, resulting in a stall and crash on adjacent property.

What happened

The pilot experienced spatial disorientation while maneuvering the aircraft on the ground at an airport that was not his home base. Despite this condition, he proceeded to initiate takeoff with the wind blowing from behind the aircraft. During the initial climb, the pilot recognized that the flight path would not allow the aircraft to clear trees and a populated area located at the end of the runway.

In an effort to avoid these obstacles, the pilot attempted a sharp turn to the left. The maneuver caused the aircraft to lose airspeed rapidly, resulting in an aerodynamic stall. The aircraft subsequently crashed onto a golf course situated adjacent to the airport boundaries.

The investigation

The investigation focused on the sequence of events leading to the loss of control. Key factors included the pilot's disorientation during taxiing and the decision to depart into the wind. The mechanical examination of the aircraft confirmed that the stall was aerodynamic in nature, induced by the low-speed turn.

Findings

Contributing factors to this accident include:

  • Pilot disorientation during ground operations at an unfamiliar location
  • Takeoff performed with a downwind component
  • Inadequate obstacle clearance during initial climb
  • Loss of control due to stall following a low-altitude turn

The crash resulted in significant damage to the aircraft and occurred on private property adjacent to the airfield.

Safety message

Pilots operating at unfamiliar airports should exercise extreme caution during ground operations to avoid disorientation. Additionally, takeoff performance calculations must account for wind direction; departing downwind significantly increases ground roll and reduces climb gradient, potentially compromising obstacle clearance.

Probable cause

The pilot's failure to maintain aircraft control during the initial climb, which resulted in a stall, due to his decision to take off downwind at an unfamiliar airport where he had become disoriented.
