Incident Details
A flight instructor (CFI) was conducting an instructional flight and received a clearance to execute the localizer runway 10 approach to Mount Washington Regional Airport. The airport's runway measures 3,495 feet in length. The CFI intended to make a full-stop landing.
Landing Conditions
The CFI estimated approximately a quarter of an inch of standing water on the runway. Surface winds were reported as 300 degrees at 15 knots, gusting to 20 knots. Due to the landing environment, the CFI decided to land the airplane herself, feeling it might be too difficult for her student. She maintained 90 mph on final approach because of the wind gusts.
Runway Excursion
According to the CFI, the airplane touched down on the centerline approximately halfway down the runway. After touchdown, the brakes had no effect, and directional control was marginal. The airplane then departed the runway.
