Allegiant Airline's pilots' union released a report Monday claiming the airline's maintenance practices were “dangerous and not up to industry standards."
The Teamsters Union Airline Division has been complaining about mechanical problems on flights all across the country.
The report, written by the Aviation Mechanics Coalition, documents 98 "preventable" mechanical problems on Allegiant flights from September 2015 to January 2016. The report indicates 10 of those flights were scheduled to depart or arrive at Phoenix-Mesa Gateway Airport.
Allegiant issued a statement in response to the report calling it "unfounded" and indicating it may be an effort by the union to leverage pilot contract negotiations.
The company says Allegiant is a safe airline, and its maintenance program goes above and beyond manufacturer and FAA recommendations and guidelines.
