In-Flight Breakup Over Gulf of Mexico Near Marco Island (N9049S)

Marco Island, FL, US

On March 25, 1997, a Beech V35 (registration N9049S) operated by John S. Spriggs was involved in an aviation accident near Marco Island, FL. Investigators recorded the probable cause as: inadvertent flight by the pilot into adverse weather conditions (severe thunderstorms), which led the design stress limits of the airplane being exceeded, subsequent in-flight break-up of the airplane, and an uncontrolled collision with water. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
