A PSA Airlines Canadair CRJ-200 on behalf of US Airways, registration N246PS performing flight JIA-2495/US-2495 from Charleston,WV to Charlotte,NC (USA) with 30 passengers and 3 crew, overran runway 23 after rejecting takeoff at high speed at 16:13L (21:13Z) and got to a stop in the EMAS (Engineered Material Arrestor System) past the end of runway 23. No injuries occured, the airplane received substantial damage and probably needs its landing gear replaced.The airport had to be closed for about 5.5 hours until the airplane was removed from the arrestor bed.The airport reported, that the airplane aborted the takeoff and came to a stop about 130 feet (40 meters) down the EMAS. The EMAS, which was installed in 2007, worked perfectly.
A standard EMAS installation extends 600 feet from the end of the runway. An EMAS arrestor bed can still be installed to help slow or stop an aircraft that overruns the runway, even if less than 600 feet of land is available.
(EMAS) is a bed of lightweight, crushable concrete built at the end of a runway. The purpose of an EMAS is to stop an aircraft overrun with no human injury and minimal aircraft damage (usually none). The aircraft is slowed by the loss of energy required to crush the concrete blocks. An EMAS is similar in concept to the runaway truck ramp made of gravel. It is intended to stop aircraft that have overshot a runway when there is an insufficient free space for a standard runway safety area (RSA).
Currently, EMAS is installed at 42 runway ends at 28 airports in the United States, with plans to install 6 EMAS systems at 6 additional U.S. airports.
EMAS Arrestments
To date, there have been four incidents where the technology has worked successfully to arrest aircraft which overrun the runway and in several cases has prevented injury to passengers and damage to the aircraft.
