1996-07-17: American Champion (acac) 7EC (N8910R) — Rochester, NH

Rochester, NH, US

On July 17, 1996, an American Champion (acac) 7EC (registration N8910R) was involved in an aviation accident near Rochester, NH. Investigators recorded the probable cause as: The pilot's failure to maintain directional control during the landing rollout due to a gust of wind that caused the airplane to weathervane and ground loop. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A light aircraft veered off the runway after touchdown when a gust of wind caused it to weathervane and ground loop, resulting in right wing damage.

What happened

The pilot and a single passenger were conducting a landing operation on runway 33 at their destination airport. Upon initial contact with the pavement, the aircraft began its deceleration phase. The pilot reported intentionally lowering the tail of the airplane to facilitate braking or control during this rollout.

Shortly after touchdown, a gust of wind affected the aircraft's directionality. This wind event caused the airplane to weathervane, leading to a ground loop. During this uncontrolled rotation, the right wing struck the ground surface. The pilot estimated the wind conditions at the time were from 300 degrees at 8 knots.

The investigation

The investigation relied primarily on the pilot's statement regarding the sequence of events. No mechanical failure was identified as a contributing factor to the loss of directional control during the landing rollout.

Findings

The primary factors leading to this incident were the gusty wind conditions and the resulting ground loop. The right wing sustained damage from striking the runway surface. The pilot reported no injuries to themselves or the passenger, who were not injured. The aircraft type involved was a tailwheel-equipped airplane, which is susceptible to weathervaning in crosswind conditions.

Safety message

Pilots operating tailwheel aircraft should be aware of the increased risk of ground looping during landing rollouts, particularly when gusty winds are present. Proper use of rudder and brake inputs may help maintain directional control.

Probable cause

The pilot's failure to maintain directional control during the landing rollout due to a gust of wind that caused the airplane to weathervane and ground loop.
