What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: copilot received ptk ATIS which reported braking action by a bandeirante EMB110 was nil. A later report from company dispatch informed the crew that runway sanding was underway. A braking report from a Cessna citation, which had just landed, reported braking action fair on runway 9-27R. Based on this information, the crew decided to continue to ptk and land there. The crew stated the landing followed the glide slope. Initial braking and directional control were normal, but approximately 1000 feet from the end of the runway, with antiskid brakes applied, thrust reversers and spoilers deployed. The aircraft began to skid and drift left. The aircraft overran the end of the runway by 30 feet. The nosegear of the aircraft struck the north REIL light and relay box, receiving minor damage. The east end of runway 9-27 was not completely cleared or sanded. Personnel from the Pontiac air traffic control tower were interviewed, substantiating the pilots and copilot's reports. The aircraft flight manual performance charts for runway requirements were checked, and indicated the aircraft was within the FAR 91 operating limitations for the aircraft.
