A federal watchdog is reviewing how the Federal Aviation Administration handles allegations of improper aircraft maintenance at two U.S. airlines.
The Department of Transportation's inspector general's office will examine complaints received by the FAA and its reviews of allegations of improper maintenance practices at American Airlines and Allegiant Air, the department said in a memo Wednesday.
A segment on the CBS program "60 Minutes" last month criticized Allegiant's safety record and lawmakers called for more oversight in the wake of the report.
The watchdog announced an audit of how the FAA reviews airlines' maintenance practices in June 2017. In February, it said it planned to focus on the two carriers after an analysis of complaints sent through an FAA hotline.
