1998-09-28: Cessna 170B (N3482C) — Igiugig, AK

Igiugig, AK, US

On September 28, 1998, a Cessna 170B (registration N3482C) was involved in an aviation accident near Igiugig, AK. Investigators recorded the probable cause as: The pilot's failure to maintain adequate airspeed during takeoff, which resulted in a loss of control. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A private pilot with limited experience in the aircraft type lost directional control during takeoff from an unimproved landing area due to insufficient airspeed and crosswind conditions.

What happened

The accident occurred during the initial climb phase of flight at an off-airport landing site. The private pilot was attempting a takeoff with a variable left crosswind component. At the time of the incident, the pilot had recently acquired the aircraft and had logged approximately 15 hours of experience in this specific make and model.

According to the pilot's account, the aircraft lifted off at roughly two-thirds of the available distance along the takeoff path. However, the airspeed remained insufficient to achieve a positive rate of climb. As the aircraft failed to gain altitude, the left wing rose excessively while the right main landing gear struck the ground, resulting in damage to the aircraft.

The investigation

The investigation focused on the operational circumstances surrounding the takeoff. Key factors included the pilot's limited experience with the specific aircraft type and the use of an unimproved landing area which may have affected performance calculations. The variable wind conditions were noted as a contributing factor to the directional control issues experienced during the critical takeoff phase.

Findings

The primary factors leading to the accident included the pilot's failure to maintain adequate airspeed during takeoff and the resulting loss of control. The limited experience of the pilot in this specific aircraft type contributed to the inability to manage the performance requirements for the given conditions. The variable left crosswind further complicated the directional control, leading to the ground impact.

Safety message

Pilots operating from unimproved or off-airport landing sites must carefully evaluate available distance and wind conditions. Adequate airspeed management is critical during takeoff to ensure a safe climb gradient, especially for pilots with limited experience in the specific aircraft type.

Probable cause

The pilot's failure to maintain adequate airspeed during takeoff, which resulted in a loss of control.
