An airline trade group expects the Boeing 737 MAX 8 will be sidelined for at least 10-12 weeks, though federal regulators will have the final say.

The aircraft has been involved in two deadly crashes: Last October's Lion Air crash in Indonesia and Sunday's Ethiopia Airlines disaster.

The United Kingdom and the European Union's aviation safety agency have banned Boeing 737 MAX aircraft planes from its airspace after the fatal Ethiopian Airlines crash that killed 157 people this weekend.
