Delta Air Lines Flight 1086
Delta Air Lines Flight 1086 was a scheduled Delta Air Lines domestic passenger flight between Atlanta and New York's LaGuardia Airport. On March 5, 2015, the McDonnell Douglas MD-88 aircraft veered off the runway shortly after landing at LaGuardia Airport in New York City. The plane ran up the seawall berm and struck the perimeter fence, sliding along it for approximately 940 feet (290 m) before coming to rest with the nose of the aircraft hanging over the berm above Flushing Bay. There were no fatalities, although 29 people suffered minor injuries. The aircraft was seriously damaged and written off.
The final report by the National Transportation Safety Board (NTSB) found the probable cause of the accident was the pilot's "inability to maintain directional control of the airplane due to his application of excessive reverse thrust, which degraded the effectiveness of the rudder in controlling the airplane's heading."
The aircraft involved was a McDonnell Douglas MD-88, registered as N909DL, with serial number 49540, manufactured in July 1987, and delivered new to Delta on December 30, 1987. It had accumulated 71,196 total flight hours and 54,865 total flight cycles prior to the accident.
Regularly scheduled 600-flight hour, 2200-flight hour, and 760-day maintenance checks were completed in the six months prior to the accident, all with no discrepancies. The aircraft's last major maintenance check was on September 22, 2014, in Jacksonville, Florida, and included, among other things, tests of the autobrake, anti-skid and auto-spoiler systems. The aircraft's last overnight service check was completed March 2, 2015 in Tampa, Florida.
In command was 56-year-old Captain Theodore W. Lauer, a former United States Air Force (1980–1989) pilot who had joined Delta in August 1989. He had 15,200 flight hours, including 11,000 hours on the MD-88 and MD-90.
His co-pilot was 46-year-old First Officer David W. Phillips, who had been with Delta since 2007 and had logged 11,000 flight hours, with 3,000 of them on the MD-88 and MD-90. He previously served as a United States Navy pilot from 1991 to 2012. Other members of the flight crew were not publicly identified.
Flight 1086 took off from Hartsfield–Jackson Atlanta International Airport at 8:45am EST, and was scheduled to land at LaGuardia Airport at 10:48 am. LaGuardia Airport was under falling snow and freezing fog conditions at the time of arrival, with the captain reportedly telling passengers that weather problems could cause a delay. Another Delta Air Lines MD-88 had landed on runway 13 about three minutes prior to Flight 1086. The pilots of this preceding flight confirmed that air traffic controllers relayed the braking action reports to the flight crew of Delta 1086; these reports were based on pilot reports from two other flights that landed several minutes prior to flight 1086. Both earlier flights had reported the braking action on the runway as "good". Statements by the pilots to the NTSB after the crash revealed that the runway appeared all white (covered with snow) when the airplane descended out of the overcast, seconds before landing.
The aircraft was approaching runway 13 to land on what appeared to be a normal final approach. The aircraft was aligned with the runway centerline, the autopilot remained engaged until the aircraft was about 230 feet (70 m) above ground level, and airspeed during the final approach was about 140 knots (160 mph; 260 km/h), and 133 knots (153 mph; 246 km/h) at touchdown. The aircraft touched down at 11:02 am with the main landing gear close to the runway centerline. The MD-88 veered off the left side of the runway shortly after touchdown, about 3,000 feet (910 m) from the approach end of the runway, on a heading approximately 10 degrees left of the runway heading. The MD-88 skidded left across the snowy airfield until about 4,100 feet (1,200 m) from the approach end of the runway, when the aircraft ran up the berm and the left wing struck the airport perimeter fence. It then was forced back onto a heading parallel with runway 13, and continued sliding in this direction for another 900 feet (270 m) along the perimeter fence, before coming to rest about 5,000 feet (1,500 m) from the approach end of runway 13, with the nose of the aircraft hanging over the berm. The left wing of the aircraft destroyed approximately 940 feet (290 m) of airport perimeter fence.
