The U.S. Department of Transportation’s Federal Aviation Administration (FAA) proposes a $91,500 civil penalty against Air Methods Corp. of Englewood, Colo., for allegedly operating a Bell 407 helicopter when it was not in compliance with Federal Aviation Regulations.

The FAA alleges that Air Methods operated the aircraft on four flights in October 2014 when a required torque check inspection on its tail rotor drive shaft components was overdue. As a result, the aircraft was not in an airworthy condition during those flights, the FAA alleges.
The agency further alleges that after the company performed the inspection, it failed to update the aircraft log books to show the inspection had been done and indicate when the next one was due.

Air Methods has been in communication with the FAA about the case.
