Transport Canada issued an airworthiness directive late last week for operators of the Airbus A220. It follows a problem with water dripping into the forward avionics bay. Operators of the A220 have 12 months to comply. Otherwise, they will not be able to operate the A220 in Canada. (simpleflying.com) 更多...
The article states that the engine shutdown occurred after water got into an avionics bay, because the main cabin door was left open while taxiing in a rainstorm. Obviously this couldn't happen while airborne and the loss of an engine while taxiing is hardly an emergency.
But my bigger question here... With all the backup and redundancy in these a/c... How can just 1 Circuit Breaker cause an "In Flight Shut Down".... That is a bigger problem to me than water in the Electronics Bay!
Losing an engine due to 1 Circuit Breaker is 100% unacceptable. How did the plane even get certified.... Glad the other Circuit Breaker did not pop, or they may have had another "Gimli Glider" - That series of A/C needs to be grounded until they get a FIX.... That is worse than the 737 Max issue.
If water can enter a critical area, other, even nastier substances, can too. Since Canada tends to get lots of wet snowy weather, this is a problem they need to address ASAP.
