On February 1, 2007, a Cessna 414A (registration N6631C) was involved in an aviation accident near Dickinson, ND. Investigators recorded the probable cause as: The undetermined failure of the emergency landing gear system and the retraction of the right main landing gear during landing. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During landing, the right main landing gear retracted, causing substantial damage. The pilot had previously experienced gear indication issues and attempted emergency extension.
Incident Details
The airplane sustained substantial damage when the right main landing gear retracted upon landing. The pilot reported that during approach, when attempting to lower the landing gear, both main landing gear indications did not show a down and locked condition.
Pilot Actions
After several attempts at recycling the landing gear, the pilot tried the emergency gear extension method. Despite these efforts, both main landing gear indications remained not down and locked. The pilot then contacted an individual at the airport who informed the pilot that the main gear appeared to be down from an external visual check. Subsequently, the pilot attempted to land the airplane, during which the right main gear retracted.
Post-Accident Examination
A post-accident examination of the landing gear system revealed no anomalies.
