FAA issues emergency directive on Boeing 737 Max after Lion Air crash

WASHINGTON (Reuters) - The U.S. Federal Aviation Administration (FAA) on Wednesday issued an emergency airworthiness directive on about 250 Boeing 737 Max aircraft after the U.S. aircraft manufacturer sent a bulletin to carriers in the aftermath of a deadly Lion Air flight.

The FAA said the order is effective immediately and covers 45 aircraft in the United States operated by carriers including Southwest Air Co, United Airlines and American Airlines Group Inc and addresses erroneous angle of attack inputs.

The directive orders operators to revise the airplane flight manual to give the flight crew horizontal stabilizer trim procedures to follow under some conditions.
