On February 19, 1990, a Piper PA-31T1 (registration N222GW) was involved in an aviation accident near Chamblee, GA. Investigators recorded the probable cause as: The pilot misjudged the landing sink rate because of a fogged windscreen, leading to a failure to flare prior to touchdown. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During an instrument landing system approach in IMC, the airplane landed hard, collapsing the right main landing gear. The windscreen was fogged; the pilot did not use the defroster and reported no mechanical issues. The pilot misjudged the sink rate due to fog and failed to flare.
Accident Details
The airplane conducted an instrument landing system (ILS) approach in instrument meteorological conditions (IMC).

Probable cause
The pilot misjudged the landing sink rate because of a fogged windscreen, leading to a failure to flare prior to touchdown.
