The FAA proposed two civil penalties totaling $633,000 against Bridgeton, Mo.-based Trans States Airlines last month for alleged maintenance violations involving two Embraer ERJ145s.
In the first case, the FAA alleges Trans States improperly installed replacement radio altimeter antenna cables on two airplanes and then operated the noncompliant airplanes on 268 revenue flights. Inspectors found the new cables lying unsecured to the airframe inside each aircraft’s large aft wing-to-fuselage fairing rather than mounted to the walls. The violation would carry a fine of $322,000.
The FAA also alleges Trans States operated one of the same airplanes on 3,392 revenue flights after improperly installing electrical wiring in the fuel supply system. The FAA alleges mechanics spliced the wires too close to the fuel tank. That violation would carry a fine of $311,000.
The FAA discovered the alleged violations during inspections in 2009, after Trans States returned the leased aircraft to their owner.
Trans States had 30 days from receipt of the civil penalty letters to respond to the agency.
