In bow to pressure, Boeing pulls Max 7 safety waiver appeal

Boeing Co. withdrew a request for a key safety exemption that would have helped speed approval of its coming 737 Max 7 aircraft, bending to rising pressure to prioritize safety in the wake of a near-catastrophe on one of its planes.

The concession on the de-icing requirement comes days after Democratic Senator Tammy Duckworth called on the Federal Aviation Administration to reject the company's petition for a waiver for the yet-to-be-certified Max 7.

The US planemaker will instead engineer a solution to address the engine inlet de-icing system during the certification process, Boeing said in a statement late Monday.
