MUMBAI: The US aviation regulator has warned airlines operating Boeing 737 MAX aircraft to limit engine anti-icing as under certain circumstances, the outer casing of the engine could overheat beyond its design limit and break away midair. The broken part could damage the aircraft or injure passengers in window seats seated in the rear section of the aircraft, the Federal Aviation Administration (FAA) airworthiness directive released on Tuesday said.
Under the directive, by August 25, airlines operating
Boeing 737 aircraft equipped with CFM LEAP-1B series turbofan engines
will need to revise their flight manual to limit the use of engine anti-ice in dry air to under five minutes.
