1986-08-20: Republic RC-3 (N113G) — Keego Harbor, MI

Keego Harbor, MI, US

On August 20, 1986, a Republic RC-3 (registration N113G) was involved in an aviation accident near Keego Harbor, MI. Investigators recorded the probable cause as: The pilot's failure to properly extend the flaps during the landing approach, which resulted in him lowering the landing gear instead, causing the aircraft to flip over upon touchdown. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot preparing for a water landing at low altitude mistakenly deployed the aircraft's landing gear rather than the flaps, resulting in an immediate rollover upon touchdown and substantial damage to the airframe.

What happened

The pilot was conducting a landing operation on a lake surface. As the aircraft descended to an approximate altitude of 100 feet, the pilot realized that the flaps were not fully extended. In an attempt to correct this configuration error, he reached down to manipulate the controls. By mistake, he lowered the landing gear instead of deploying the flaps. Upon touchdown, the aircraft immediately flipped over, sustaining substantial damage to the wings and hull.

The investigation

The investigation focused on the sequence of events leading to the accident. The pilot's account indicated that the error occurred during the critical final approach phase. The mechanical failure was not attributed to a malfunction but to human error in control input. The aircraft sustained substantial damage to the wings and hull as a result of the rollover.

Findings

The primary factor contributing to the accident was the pilot's incorrect control input. The pilot intended to lower the flaps but inadvertently lowered the landing gear. This error occurred at a low altitude, leaving insufficient time or height to recover from the resulting loss of lift and subsequent rollover. The aircraft sustained substantial damage to the wings and hull.

Safety message

Pilots should verify control configurations carefully during critical phases of flight. Misidentification of controls can lead to catastrophic outcomes, especially at low altitudes where recovery options are limited.

Probable cause

The pilot's failure to properly extend the flaps during the landing approach, which resulted in him lowering the landing gear instead, causing the aircraft to flip over upon touchdown.
