Terre Haute, IN, US

On June 28, 1986, a Beech 58 (registration N29CP) was involved in an aviation accident near Terre Haute, IN. Investigators recorded the probable cause as: The pilot's decision to ground loop the aircraft to avoid a dropoff at the end of a short runway, which resulted in the collapse of the left main landing gear. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.

A pilot executed a ground loop to avoid a dropoff at the end of a short runway, resulting in left main gear collapse despite reported brake failure.

What happened

The pilot reported that the left brake failed while rolling out on a runway measuring 3,200 feet in length. The landing was performed with a significant crosswind component, specifically a 20-degree right quartering tailwind of 10 knots. Concerned about running off the departure end of the runway and encountering a 50-foot dropoff, the pilot initiated a ground loop to the right to maintain directional control.

The investigation

Following the accident, investigators examined the main gear braking system for mechanical issues. The post-accident examination found no defects in the braking system components, contradicting the pilot's initial report of brake failure.

Findings

The sequence of events was driven by the combination of a short runway and challenging wind conditions. The decision to ground loop was made to prevent a runway excursion into hazardous terrain. The structural failure resulted directly from the forces generated during this maneuver rather than mechanical brake failure.

Probable cause

The pilot's decision to ground loop the aircraft to avoid a dropoff at the end of a short runway, which resulted in the collapse of the left main landing gear.
