The National Transportation Safety Board (NTSB) has found that the probable cause for the crash of a de Havilland DHC-3 in Soldotna, Alaska, on July 7, 2013, was the operator’s failure to determine the actual cargo weight, leading to the loading and operation of the airplane outside of its weight and center of gravity limits.
Contributing to the accident was the Federal Aviation Administration’s failure to require weight and balance documentation for this type of air taxi flight.
