The National Transportation Safety Board has issued an urgent safety recommendation to the FAA and Transport Canada that all operators of de Havilland Canada DHC-3s conduct an immediate inspection on the horizontal stabilizer of the aircraft. The recommendation is in response to information garnered during the investigation of the loss of a DHC-3 Otter turboprop in Washington that killed 10 people.
The NTSB notes the recommendation is to “conduct an immediate one-time inspection of the horizontal stabilizer actuator lock ring in accordance with the instructions in the Viking Air Limited service letter and report their findings to the FAA and Transport Canada, respectively.”
