Taxiing

During the push back process, the pilots noticed smoke spreading in the cockpit and in the cabin and stopped the aircraft. All 196 occupants were evacuated but some were standing on wings and jumped down to the tarmac. 27 passengers were injured, some of them seriously. The aircraft was considered as damaged beyond repair due to smoke.

Registered N865AS, the landed at Saint George Airport, Utah, at 2236LT after completing flight DL7772 from Salt Lake City. All occupants deplaned and the aircraft was parked on the ramp for the night. Shortly after midnight, a commercial pilot climbed over the barbed wire fence, open the door of the aircraft (which was not closed by key) and managed to start the engines. The aircraft rolled for several metres before then impacted the terminal building, went through the fence and came to rest in a parking lot. The pilot shot himself in the cockpit. Polices forces confirmed later that he wanted to stole the aircraft after his girlfriend was killed that day in Colorado Springs.

The pilots reported that the cargo airplane was about 60 pounds over its maximum takeoff weight. Because their taxi to the assigned runway was long, they decided to reduce weight by using higher-than-normal engine power settings to burn fuel before takeoff while using the wheel brakes to control the airplane’s speed while taxiing. During the taxi, a fire ignited in the right wheel housing. The pilots brought the airplane to a stop on the taxiway, evacuated, and attempted to extinguish the fire with two handheld fire extinguishers. Airport firefighting personnel arrived on scene and extinguished the fire using foam suppressant. Although the fire damage was extensive, postaccident examination of the airplane did not show evidence of mechanical malfunctions or failures with the wheel and brake system that could have caused the fire. The right and left main landing gear tires deflated when the fusible plugs in the wheels blew due to overheating. The fusible plugs are designed to “fail” if the wheels overheat, and those plugs functioned as designed. The pilots stated that they had been trained to not ride the brakes while taxiing. However, the captain stated that he did not realize that he was in danger of blowing the tires much less causing a fire, otherwise he would not have attempted to bum off excess fuel while taxiing.

Following an uneventful cargo flight from Christiansted-Henry E. Rohlsen Airport, the crew completed the landing normally at San Juan-Luis Muñoz Marin Airport. While taxiing to the ramp, the nose gear collapsed and the aircraft came to rest. Both pilots escaped uninjured and the aircraft was damaged beyond repair.

A technician was in charge to ferry the airplane to a hangar for a maintenance control. While taxiing, the Falcon went out of control, rolled down an embankment and collided with a utility pole. The nose was severely damaged and the aircraft was damaged beyond repair. According to the technician, who escaped uninjured, the brakes failed while taxiing.

On 14 July, 2011 ATR 72 flight crew after landing at EPWA aerodrome received the clearance for taxiing to parking stand 41 via taxiways: "S", "O" and "M". When the airplane was on taxiway "M2", "Mulag" type tractor was moving by the service road, passing perpendicularly to taxiway “M2”. The tractor driver did not give the right of way to ATR 72 and the tractor collided with the airplane. As a result, the airplane and the tractor sustained substantial damages. The flight crew stopped the airplane and shut down the engines. Airport Fire Brigade and an ambulance were called. The tractor operator suffered some injuries and was taken to hospital. the airplane passengers and the flight crew did not suffer any injuries. The impact caused a fuel leakage from the airplane of 200 m2 in area, which was removed along with other elements of the damaged aircraft by the Airport Fire Brigade. The airplane and the "Mulag" tractor were withdrawn from the further service. During the accident there were adverse weather conditions at the airport - heavy rain and lightning which caused reduction in visibility.

The crew was preparing the aircraft to perform a cargo flight to Calgary (flight NRL920). While taxiing, the aircraft went out of control, collided with a parked Ameriflight Piper PA-31 before coming to rest against a metallic fence. Both pilots were uninjured while the aircraft was damaged beyond repair.

While taxiing at Papeete-Faaa Airport, the aircraft went out of control and collided with various ground handling equipment such as a catering truck, a belt loader and cargo containers. There were no injuries but the aircraft was damaged beyond repair.

The aircraft was flown on a non-scheduled charter flight from O. R. Tambo International Airport to Hoedspruit military aerodrome, where it landed safely and all 97 passengers disembarked. The crew then prepared to return to O. R. Tambo International Airport with no passengers on board. Whilst taxiing to the cleared holding point for takeoff, the pilot switched off the landing lights to avoid blinding an approaching aircraft. As a result, he overshot the turning point in the darkness and found himself at the end of the taxiway with insufficient space to turn around. According to him, he decided to manoeuvre the aircraft out of the "dead end" by turning into the last taxiway, which led to military hangars, and then reversing the aircraft to carry out a 180° turn. This was to be done without external guidance. Whilst reversing the aircraft, the pilot failed to stop it in time, the main wheels rolled off the edge of the taxiway and the aircraft slipped down a steep embankment, coming to rest with the nose-wheel still on the taxiway. The aeroplane was substantially damaged, but no-one was injured.

Following an uneventful night cargo flight from Brasília, the aircraft landed at São Paulo-Guarulhos Airport. While taxiing, the aircraft hit airport equipment while approaching its stand. The aircraft was severely damaged on its nose and cockpit area. All three occupants escaped uninjured while the aircraft was damaged beyond repair. The encountered brakes problems.
