TACA International Airlines Flight 110 was the flight number of a TACA scheduled flight between Belize City , Philip SW Goldson International Airport , and Louis Armstrong New Orleans International Airport , USA , in 1988. Due to a failure of both engines, the pilots had to make an emergency landing on a grassy levee in New Orleans . The dike belonged to NASA's Michoud site .
Boeing engineers and the pilots decided to start the machine from a nearby embankment after changing the engine, instead of transporting it away with a barge. Any repairs due were carried out after the transfer at Louis Armstrong Airport.
Course of the flight
The Boeing 737-300 with the registration number N75356 was en route from Belize to New Orleans on May 24, 1988. There were 38 passengers and 7 crew members on board. During the descent from 35,000 ft (approx. 10,700 m) to land in New Orleans, the aircraft got into a severe storm with heavy rain and hail. Both engines failed at an altitude of 16,500 ft (approx. 5,000 m). The crew was able to maintain the emergency power supply with the aid of the auxiliary power unit . Restarting the engines did not lead to usable thrust and resulted in critical overheating, so that the engines had to be switched off again.
The ditch plan was discarded after the captain discovered a patch of grass between the Intracoastal Waterway and a narrow ditch ( 30 ° 0 ′ 43 ″ N , 89 ° 55 ′ 11 ″ W ). As it turned out later, this had a length of 1850 m. After landing, all passengers were able to exit the aircraft using the evacuation slides .
root cause
The investigations by the US Aircraft Accident Investigation Authority (NTSB) revealed that the storm with hail caused an engine failure, although the limit values for sucking in water had not yet been exceeded. However, in the course of the investigations it turned out that the engine power was automatically and systematically reduced by the autopilot before the failure during the descent. Due to the resulting decrease in the speed of the turbine blades, the penetrating water could no longer be conveyed sufficiently to the outside, it collected inside and ultimately caused the failure. The aircraft suffered only minor damage from the hail; the second engine was damaged by overheating when attempting to restart.
Consequences
As a result, the engines of this type were modified and provided with flaps to drain large amounts of rainwater.
Whereabouts
The aircraft was later sold and flew for Southwest Airlines , among others . At the beginning of December 2016 it was decommissioned and parked at the Pinal Airpark .
Other incidents with all engine failures
- Southern Airways Flight 242 : On April 4, 1977 faced a McDonnell Douglas DC-9 of Southern Airways on a highway in Georgia emergency landing after both engines failed by a hailstorm. The machine crashed during the emergency landing and went up in flames. 63 inmates and 9 people died on the ground, 22 inmates survived the crash injured.
- British Airways Flight 9 : 1982 became a 747-200 of the British Airways approximately 11,000 meters in the plume of the volcano Mount Galunggung , which failed, all four engines. They could be started again, one failed again shortly afterwards.
- KLM flight 867 : In 1989 a Boeing 747-400 operated by KLM Royal Dutch Airlines got into the ash cloud on Mount Redoubt . All four engines of the Boeing 747-400 failed, but could be restarted. Normal landing in Anchorage.
- Air Canada Flight 143 : 1983 had a Boeing 767-200 of Air Canada emergency landing due to lack of fuel. The incident is known in the press as the Gimli Glider . The cause was an incorrect conversion between metric and Anglo-American units for the fuel load.
- Hapag-Lloyd flight 3378 : On July 12, 2000, an Airbus A310 operated by Hapag-Lloyd from Chania to Hanover had to make an emergency landing shortly before Vienna-Schwechat airport . The on-board computer calculated that the fuel would last as far as Munich, but did not take into account the air resistance of the half-retracted landing gear .
- Air Transat flight 236 : An Airbus A330 had to make an emergency landing on August 24, 2001 in the Azores because of a leak in the fuel line. However, the fuel ran out because the defective line was still being used instead of shutting down the associated engine and continuing to fly with a single engine.
- Garuda Indonesia flight 421 : On January 16, 2002, a Garuda Indonesia Boeing 737-300 had to make an emergency landing on the Solo River after both Boeing engines failed after flying through a hailstorm. A flight attendant was killed.
- US Airways flight 1549 : A US Airways Airbus A320-200 had to make an emergency landing on the Hudson River in New York City on January 15, 2009 , as both engines failed due to a bird strike. All 155 inmates survived.
