On April 6, 1972, a Beechcraft E18 (registration N50W) operated by D. W. Winkelman was involved in an aviation accident near Skaneateles, United States of America during takeoff. 3 people were killed. Investigators recorded the probable cause as: Uncontrolled descent after takeoff following a partial loss of power on the right engine. Factors: Improper operation of powerplant & powerplant controls; Improper operation or failed to use the anti-icing/deicing equipment; Ice carburetor; Conditions… This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

Shortly after takeoff from Skaneateles Airfield, a twin-engine airplane lost power in the right engine, crashed into Lake Skaneateles, killing the pilot and two passengers and injuring three others.

Accident Overview

On an unspecified date, a twin-engine airplane departed from Runway 10 at Skaneateles Airfield. During the initial climb, the right engine experienced a loss of power. The pilot subsequently lost control of the aircraft, which crashed into Lake Skaneateles. The accident resulted in the deaths of the pilot and two passengers, while three other occupants sustained injuries. The aircraft was destroyed.

Probable Cause and Contributing Factors

The official probable cause of the accident was determined to be an uncontrolled descent after takeoff following a partial loss of power on the right engine. The investigation identified the following factors:

  • Improper operation of the powerplant and powerplant controls
  • Improper operation or failure to use anti-icing/deicing equipment
  • Carburetor ice
  • Conditions conducive to carburetor or induction system icing
  • Inadequate preflight preparation
  • Airport conditions
  • Low ceiling and snow
  • Takeoff from a strip too short to attain VMC speed
  • Operation near gross weight and aft of center of gravity

Sequence of Events

According to the official report, the aircraft took off from Skaneateles Airfield’s Runway 10. Immediately after departure, while climbing, the right engine lost power. The pilot was unable to maintain control, and the airplane descended into Lake Skaneateles. Emergency responders arrived at the scene, but the pilot and two passengers were pronounced dead, while three other occupants were transported for medical treatment.

Aircraft and Operational Conditions

The airplane was equipped with two engines, the right of which failed. The investigation noted that the takeoff was conducted from a runway that was too short to allow the aircraft to reach VMC speed (minimum control speed with one engine inoperative). Additionally, the aircraft was near its maximum gross weight and had an aft center of gravity. Weather conditions at the time included low ceilings and snowfall, which may have created icing conditions. The pilot’s preflight preparation was found to be inadequate, and the anti-icing equipment was either improperly operated or not used. Carburetor ice was present, and the conditions were conducive to icing.

Investigation and Findings

The official investigation concluded that the combination of engine power loss, operational deficiencies, and environmental factors led to the loss of control and subsequent crash. The report emphasized the improper handling of the powerplant and the failure to address icing conditions. The airport environment also played a role, as the runway length was insufficient for the aircraft’s weight and configuration to achieve the necessary speed for safe single-engine flight.
