FAA issues emergency 737 Max airworthiness order

The FAA has issued an emergency order addressing the risk that faulty angle-of-attack inputs could cause Boeing 737 Max horizontal stabilisers to put the aircraft into a difficult-to-control dive. "Possible erroneous angle-of-attack inputs on Boeing 737 Max aircraft… can potentially make the horizontal stabilisers repeatedly pitch the nose of the airplane downward, making the aircraft difficult to control," says the FAA in a Nov 7 emergency airworthiness directive. Effective immediately, the FAA orders US operators to revise flight manuals "to give the flight crew horizontal stabiliser trim procedures to follow under certain conditions", the order says. The FAA gives operators 3 days to make the updates. The FAA's order targets the latest generation of Boeing's best-selling 737. <br/>
