The pilot’s decision to continue to the destination landing platform in weather conditions below the company’s weather minimums and his failure to maintain aircraft control during the approach. Contributing to the passenger fatality and the severity of the occupant injuries were the lack of a passenger briefing on how to deploy the liferaft, which was required by the company but not by the Federal Aviation Administration because this flight was not an extended overwater operation; the pilot’s failure to deploy the liferafts; and the company radio operator’s misreporting of the helicopter’s “landed” status, which delayed the rescue response.
