On January 19, 2010, the flight crew of PSA Airlines, doing business as US Airways Express flight 2495, rejected the takeoff of a Canadair CRJ-200ER, N246PS, which subsequently ran off the runway end and then stopped in the engineered materials arresting system (EMAS) installed in the runway end safety area at Yeager Airport (CRW), Charleston, West Virginia.
None of the 31 passengers (including one lap-held child) or 3 crewmembers sustained injuries, and the airplane received minor damage.
The incident flight was the fifth flight for the flight crewmembers in the first day of a 3-day trip sequence, and they were scheduled to be on the ground at CRW for about 30 minutes. The first officer stated that, during that time, he completed a walk-around inspection of the airplane and received the takeoff performance data via the aircraft communications addressing and reporting system (ACARS). The ACARS performance data included the following: takeoff weight 44,400 pounds, takeoff flap setting 20, FLEX 33 takeoff thrust setting (reduced thrust takeoff), V1 (takeoff decision speed) of 127 knots, and Vr (rotation speed) of 128 knots. The captain was the flying pilot for the incident flight.
According to cockpit voice recorder (CVR) information, the flight crew completed the Before Start checklist at 1554:25 LT. At 1558:51, the captain made a public address announcement indicating that the departure would be delayed about 15 minutes. At 1602:35, the first officer notified the local controller (LC) that the airplane was ready to taxi, and the LC instructed the flight crew to hold the airplane on the ramp. About 1 minute later, the flight crew started a personal conversation after setting the parking brake, and this conversation continued until 1607:32 when the LC instructed the flight crew to taxi to runway 23. (The LC was working both the ground and local positions.)
At 1607:40, the captain continued the nonpertinent conversation. At 1608:44, the captain stated, "flaps twenty," and then called for the Taxi checklist. FDR data indicated that, 1 second later, the flaps moved from the flaps 0 to the flaps 8 position. At 1609:02, the first officer began the Taxi Checklist, during which he stated, "flaps eight," and the captain responded, "set." At 1609:08, the first officer continued the checklist, stating, "flaps trims eight degrees," and the captain responded, "eight." The first officer completed the Taxi Checklist at 1609:13.
The captain continued the nonpertinent conversation from 1609:19 to 1611:47 when he called for the Before Takeoff checklist. At 1612:01, the first officer began the Before Takeoff checklist.
At 1612:05, the LC cleared the airplane for takeoff, and the first officer acknowledged the instruction. (FDR data indicate that the airplane continually taxied from its initial taxi clearance at 1607:38 until its takeoff clearance at 1612:05.) At 1612:18, the first officer continued the Before Takeoff checklist, stating, in part, "takeoff briefing. No questions." The first officer completed the checklist at 1612:27.
FDR data showed the airplane heading aligning with the runway heading and the engine thrust increasing to takeoff thrust at 1612:50. Three seconds later, the captain asked, "we’re cleared to go right?" and the first officer responded, "yup." At 1613:06, the captain stated, "set thrust," and the first officer responded, "thrust set." Four seconds later, the captain stated, "eighty
knots," and the first officer responded, "checked."
FDR data showed that, at 1613:20, the flaps position began moving from the flaps 8 toward the flaps 20 position and the speed was about 120 knots. At 1613:21, the first officer stated, "V one," at which time, the airspeed was about 127 knots. Two seconds later, the CVR recorded the sound of the airplane master warning and then the flaps and spoilers configuration aural alerts.
FDR data showed that, at 1613:25, both engine fan speeds began decreasing, the flight and ground spoilers were extended, and both of the captain’s brake pedals were depressed. The airplane reached a maximum airspeed of about 143 knots at 1613:26. At 1613:36, the first officer contacted the LC, stating, "rejecting…off the end of…runway two three."
At 1613:38, the airplane entered the engineered materials arresting system (EMAS) at an airspeed of about 50 knots, and, about 3 seconds later, it stopped about 128 feet into the EMAS arrestor bed (178 feet from the runway end). (The EMAS is set back 50 feet from the runway end.)

Probable Cause and Findings:
The National Transportation Safety Board determines the probable cause(s) of this incident to be:
(1) The flight crewmembers’ unprofessional behavior, including their nonadherence to sterile cockpit procedures by engaging in nonpertinent conversation, which distracted them from their primary flight-related duties and led to their failure to correctly set and verify the flaps;
(2) the captain’s decision to reconfigure the flaps during the takeoff roll instead of rejecting the takeoff when he first identified the misconfiguration, which resulted in the rejected takeoff beginning when the airplane was about 13 knots above the takeoff decision speed and the subsequent runway overrun; and
(3) the flight crewmembers’ lack of checklist discipline, which contributed to their failure to detect the incorrect flap setting before initiating the takeoff roll.
Contributing to the survivability of this incident was the presence of an engineered materials arresting system beyond the runway end.
