The machine was a McDonnell Douglas MD-88 with the air vehicle registration N909DL and serial number 49540th The aircraft was operating on behalf of Delta Air Lines and was owned by the Wilmington Trust Company of Wilmington , Delaware . It was built in 1987 and first registered on January 19, 1988. The machine has only been in service with Delta Air Lines since it was commissioned.
The aircraft was assembled at the Douglas factory in Long Beach, California . At the time of the accident it had a total of 71,195.54 flight hours and 54,865 flight movements. The last C-Check took place on September 22, 2014 in Jacksonville . The last A-check was carried out in Tampa on March 2, 2015.
As of March 2015, Delta owned 117 MD-88s. The average age of these types of aircraft was 24.2 years. They represent the oldest type of aircraft in the fleet.
Flight history
Flight 1086 took off from Hartsfield – Jackson Atlanta International Airport at 8:45 am local time . The arrival time at LaGuardia Airport was calculated at 10:48 a.m. At the time, LaGuardia Airport was under a bank of fog during heavy snowfall. During the approach, the captain informed the passengers via loudspeaker that weather problems could delay the scheduled arrival time.
the accident
The aircraft was in the normal descent procedure on its final approach to runway 13. It was on the line of the touchdown point. The autopilot remained activated up to 70 meters above ground. The airspeed was about 140 knots on final approach and 133 knots on touchdown. At 11:02 a.m. local time, the machine touched down with the main landing gear on the runway marking. About six seconds later the MD-88 swerved 10 degrees to the left and slid on the snowy airport to about 1200 m from the end of runway 13. The left wing hit the airport fence, the machine brushed about 290 m along the fence and came then stop with your nose towards the embankment.
The structure of the machine was badly damaged. The main damage was to the profile nose , the slats , the rear lift aids and the spoilers . The tank on the left wing was moved to the lift aids. The entire lower fuselage up to the aircraft nose was badly damaged, as was the front landing gear.
The cabin crew initiated a full evacuation immediately after the accident. Meanwhile the remaining fuel ran out. 23 or 24 passengers suffered minor injuries during the evacuation process, but were released from the hospital on March 9, 2015.
Immediately after the accident, the airport was closed to incoming and outgoing traffic. Flight operations could be resumed on the other runway at around 2:30 p.m. Track 13 remained closed until the next day. At around 10:30 a.m. the following day, the emergency services declared the mission to be over and the damaged aircraft was transported to a hangar to inspect the damage.
Cause of accident
Several factors contributed to the accident. One of the causes of the incident was that the pilot flying had incorrectly adjusted the spoilers. In addition, the brake setting should have been set to "maximum". Therefore, the pilots initially assumed that the wheel brakes were defective. The NTSB , which was investigating the accident, determined that the runway was last cleared about 20 to 25 minutes before the accident. The pilots also stated that they could not prevent the drift to the left.
In its final report dated April 2, 2015, the NTSB recommended a change in the MD-88 manuals. In a slippery runway, for example, pilots should limit the engine pressure ratio (EPR) to a thrust reversal of 1.3 and not exceed this value. In the case of flight DL 1086, the EPR value rose to 1.9. This happened about six seconds after touching down.
According to an article in the Wall Street Journal on March 9, 2015, the pilots and aviation experts of the MD-88 have known for some time that when activating the thrust reverser and simultaneously drifting to the left or right, the rudder deflections are not powerful enough to counteract this.
