ARLINGTON, Virginia, April 24 (Reuters) - U.S.

Transportation Secretary Pete Buttigieg said Wednesday Boeing

must meet a government mandate to address systemic

quality-control issues within 90 days before it will be able to

boost 737 MAX production.

Buttigieg noted Boeing ( BA ) is about halfway through that 90-day

clock set by the Federal Aviation Administration (FAA) in late

February.

"We're not to going let them (increase production) until

they have satisfied to the FAA that they can do it safely,"

Buttigieg said.
