WASHINGTON-The U.S. Department of Transportations Federal Aviation Administration (FAA) proposes a $285,800 civil penalty against Exec 1 Aviation of Ankeny, Iowa, for allegedly using unqualified pilots on multiple passenger-carrying flights.

The FAA alleges that Exec 1 conducted a total of 100 flights using Citation 500 jet aircraft with 12 unqualified pilots. Seventy-nine of the flights, which occurred during a 30-day period in May and June 2015, had revenue-paying passengers on board the aircraft. The flights took place at airports throughout the U.S.

The FAA alleges the pilots were unqualified because they had failed to complete required initial or recurrent training. The training subjects included cold weather operations, engine inoperative procedures, and abnormal and emergency procedures, among other things.

Exec 1 has 30 days from receipt of the FAAs enforcement letter to respond to the agency.
