From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23)At 0436Z, 03/07/2001, chautauqua flight (us air) 4873 from lga to iad, an Embraer 145 N268SK, declared a smoke in the cockpit emergency and landed at iad on 1 right. The discrepancy was slight smoke in the cockpit area, suspected windshield heat system. The crew pulled windshield heat circuit breakers prior to landing. The crew of four and two pax successfully evacuated the aircraft using the overwing exit. The aircraft was left on 1 right, closing the runway for approximately 2 hours. The aircraft was towed to gate B-20. A FSDO inspector responded to the scene, but the crew had left and the aircraft was closed. Contact with chautauqua maintenance was established and they were trying to decide whether to send a team or repair it locally. Local contract maintenance (atlantic coast airlines) started troubleshooting the a/c. initially, the smell had diminished and maintenance was inspecting around the windshield area for windshield heat wiring problems. After power was applied, there was a smell in the f/o's lower right relay panel area. Further checking revealed that two relay bases had burned arced to the support and overheated the rubber drain tube hose from the f/o' s side window. The reminder of the wiring in the area appeared to be okay, only damage was at the base of the relay block on relay 17/18. At this time it is not known for sure what the relays controlled, but suspected windshield heat. Contract maintenance was in touch with chqutauqua maintenance control after reporting the damage and was awaiting further instructions.
