application of excessive reverse thrust during a landing at LaGuardia Airport,
New York, March, 5, 2015, led to a loss of directional control and the
passenger jet’s departure from the snow covered runway, according to findings
of the National Transportation
Safety Board announced during a public meeting here Tuesday.
flight 1086 landed on LaGuardia Airport’s runway 13, veered to the left and
departed the side of the runway, contacted the airport perimeter fence and came
to rest with the airplane’s nose on an embankment next to Flushing Bay.
NTSB investigation found that the probable cause of the accident – in which 29
of 127 passengers suffered minor injuries – was the captain’s inability to
maintain directional control of the Boeing MD -88 due to his application of
excessive reverse thrust, which degraded the effectiveness of the rudder in
controlling the airplane heading. The aircraft was substantially damaged.
passengers and crew of Delta flight 1086 were fortunate to have survived this
crash with no loss of life or serious injuries,” said NTSB
Chairman Christopher Hart. “Proper use, in real time, of precise, accurate,
and timely information about the condition of the runway can help make winter
operations safer, as well as the study and use of large quantities of data to
inform best practices. If today’s recommendations are acted upon, future
landings on contaminated runways will be safer because of actions to enable the
timely communication and use of information to eliminate potentially
NTSB investigation also revealed that, during the accident sequence, damage to
the aircraft resulted in the loss of the interphone and public address system
as methods of communication after the accident. As a result, the announcement
to evacuate the aircraft was delayed and more than 17 minutes passed before all
passengers were off the aircraft.
NTSB made 10 recommendations to the Federal
Aviation Administration, two to Boeing,
one to the U.S. operators of MD-80 series airplanes, and one to the Port Authority of New York and New Jersey.
