According to a report by Reuters, Japanese airline ANA found an electrical fault in the engine fire extinguishers on three of its fleet of 20 787s. A spokesperson for ANA told Reuters that the problem was found as a part of pre-flight maintenance on one of their 787s.
After ANA reported the problem, ANA’s competitor, Japan Air Lines, ordered a flight that was headed to Helsinki to turn around and return to the airport to determine if it had a similar fault. JAL is investigating its fleet of 787s to see if any of them suffer from the same issue.
ANA is currently investigating whether or not the fault would have prevented the fire extinguishers from functioning in case of an engine fire.
In response to the news, a spokesperson from Boeing said in an email: “We are aware of the issue and working with our customer. The safety of those flying on Boeing airplanes is our top priority. We will thoroughly examine this issue and take the appropriate steps.”
Last month, a fire broke out in the rear of a 787 parked at Heathrow Airport. The fire was blamed on an emergency beacon located above the ceiling of the cabin.
