Boeing withdraws request for safety waiver for the 737 Max 7

Boeing has withdrawn a request for the Federal Aviation Administration to grant a safety waiver for the 737 Max 7 after the manufacturer reported an issue with the Max's anti-ice system last year.

"We have informed the FAA that we are withdrawing our request for a time-limited exemption relating to the engine inlet deicing system on the 737-7," Boeing said Monday in a statement. "While we are confident that the proposed time-limited exemption for that system follows established FAA processes to ensure safe operation, we will instead incorporate an engineering solution that will be completed during the certification process."

The withdrawal follows pressure from Democratic Sen. Tammy Duckworth of Illinois, chair of the Senate Subcommittee on Aviation Safety, who last week sent a letter to the FAA demanding it reject Boeing's request.
