On January 20, 1997, a Cessna 180J (registration N42376) was involved in an aviation accident near Lopez, WA. Investigators recorded the probable cause as: The pilot's improper decision to initiate flight into marginal VFR conditions at night which led to inadvertent flight into instrument meteorological conditions, and his failure to maintain adequate clearance from terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An airline transport pilot departed a private airstrip at night in marginal VFR conditions without a weather briefing or flight plan. After takeoff, the aircraft entered clouds and fog, leading to disorientation and collision with trees and water. The aircraft was substantially damaged; pilot and passenger suffered minor injuries.
