The FAA proposes a $777,000 civil penalty against Horizon Air for operating 32 Dash-8 on almost 50,000 flights while aircraft were not in compliance with FARs.
FAA alleges Horizon installed new sets of external light systems on the aircraft, but failed to conduct required electromagnetic inteference and radio test before returning aircraft to service during a period between October 2009 and March 2010.

It would be interesting to know what the approval for installation was.
If it was an STC, then there would have been a ground and possibly a flight test to verify no interference. If Horizon was the applicant and did not include that in the package, then the ACO approving the STC should be in hot water.
If it was a SB, then there should be no issue.
If it was an internal approval (no STC or SB), then there would be an issue. Horizon may have deemed it to a minor alteration, therefore not requiring FAA approval, but you still need to verify interference with installing an electrical/electronic system. We do a test for any electronic device we install that will be operated by the company,
