The U.S. Federal Aviation Administration is proposing a $777,000 civil penalty against Horizon Air Industries for allegedly operating 32 Bombardier DHC-8-400 Dash 8 turboprop aircraft on 49,870 flights when the aircraft were not in compliance with Federal Aviation Regulations.
The FAA alleged Horizon installed new external lighting systems on the aircraft, but did not conduct required tests for radio frequency and electromagnetic interference before returning the aircraft to service. Horizon operated the aircraft between Oct. 19, 2009 and Mar. 17, 2010, before the FAA discovered the compliance problems during routine surveillance. Horizon immediately completed tests and inspections of all 32 aircraft before further flights.
Horizon Air has 30 days from receipt of the civil penalty letter to respond to the agency.
