Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot was conducting a night cross country flight in his single-engine helicopter to evaluate the progress of some construction projects. As he approached the landing area, he noticed some loose construction debris, so he flew past the site and turned around to approach from the opposite direction. Shortly thereafter, the engine began losing power. Unable to maintain level flight he conducted an emergency landing to a river. By the time he was rescued, about 11 hours after the accident, the helicopter had sunk and was not located despite an extensive search by local law enforcement. Given that the wreckage was not recovered, an examination of the engine to determine a reason for the loss of power could not be performed.
