WASHINGTON—The U.S. Federal Aviation Administration (FAA) needs to improve its oversight to address maintenance issues at Allegiant Air, the 11th largest U.S. carrier, according to a report seen by Reuters on Dec. 17.
The U.S. Transportation Department’s Inspector General, in a 31-page report sent to Capitol Hill on Dec. 17 but not yet made public, said FAA inspectors since 2011 have not “consistently documented risks associated with 36 Allegiant Air in-flight engine shutdowns for its MD-80 fleet or correctly assessed the root cause of maintenance issues.”
