WASHINGTON (Reuters) -The U.S. Federal Aviation Administration (FAA) late on Wednesday stated it was mandating U.S. DHC-3 operators shortly conduct inspections after a deadly crash in Washington state killed 10 in September.
The U.S. Nationwide Transportation Security Board (NTSB) final week issued an “pressing security suggestion” asking the FAA and Transport Canada to take “instant motion” to require inspections of the seaplanes.
The FAA is requiring visible inspections of a stabilizer part to verify a lock ring is current and accurately put in. Operators of the 63 U.S. planes should carry out the inspections inside 10 hours of flight time from the time of Wednesday’s directive and submit the outcomes to the FAA.
The directive mandates the inspection really useful by Viking Air Ltd and FAA final week.
In September, a DHC-3 entered a nose-down near-vertical descent and crashed into Mutiny Bay, Washington killing 9 passengers and the pilot. NTSB investigators discovered the horizontal stabilizer actuator, a part of the airplane’s pitch trim management system, had separated into two items.
“Fast motion must be taken to examine the actuator of DHC-3 airplanes, of which 40% function in the US, to forestall an analogous tragedy from taking place,” NTSB Chair Jennifer Homendy stated in an announcement final week.
Viking owns the manufacturing rights to the DHC-3 however doesn’t construct it. Viking Air stated final week it “continues to help the NTSB of their ongoing investigation” and famous it had issued the letter to operators.
