Somehow, these contradictory decisions were never reconciled, and the 767s went into service with both pilots and mechanics believing that drip stick tests and the associated calculations were the others responsibility, and without either having been trained to perform them. However, after thirteen years the business had run, AirAsia QZ8501 carrying 162 passengers went missing as it lost contact with air traffic control on its way from Surabaya, Indonesia to Singapore on 28th December 2014 (Bruton, 2015). Hamlin made remarkable strides in his recovery. As humans are wont to do, their instinct was to try to outrun the plane rather than dodging to one side, forcing Pearson to brake even harder. On 17 September 1979, the plane, then serving as Air Canada Flight 680 from Boston, Massachusetts, to Yarmouth, Nova Scotia, had suffered an explosive decompression in the rear bulkhead that required rebuilding the tail section and replacing or splicing most of the wiring and hydraulic lines in the back of the plane. In addition to the maintenance, On February 1, 2003, the space shuttle titled Columbia disintegrated upon reentry. Gliding a jet down to a powerless, or dead-stick landing requires a great deal of precision, since only one approach can be attempted, and a continuous descent must be made all the way to the runway with no possibility of leveling off. To arrive at the amount of fuel which he would need to request from the fuelers, he needed to subtract the amount already in the tanks from the total of 22,300 kg. The Incident The Causes Damaged Fuel Gauge Processor Crew Assumptions Unit Conversion Error Summary Lessons Learned. Air Canada Flight 143 (Part 2) Michael continues his interview with Captain Bob Pearson and Pearl Dion. The pilots turned it off, assuming a fuel pump had failed; gravity should feed fuel to the aircraft's two engines (at least in near-level flight) even without the fuel pumps operating. Regardless, however, Captain Pearson had secured a place among Canadas greatest aviators, and the plane, now known as the Gimli Glider, among its most famous aircraft. When the fuel quantity processor was sent back to Honeywell for analysis, experts discovered a bad solder between an induction coil and its terminal block in channel 2, which resulted in a gradual breakdown of the connection between these elements. Captain Pearson was an experienced glider pilot, so he was familiar with flying techniques almost never used by commercial pilots. It was Air Canadas responsibility to inform the refueling companies at its airports about the fact that its Boeing 767s measured fuel in kilograms rather than pounds, but the responsible personnel simply forgot to do so. He had no choice but to put the pedals to the floor, because directly ahead of him were two young boys on BMX bicycles, out riding on the drag strip, who had suddenly found themselves in the crosshairs of a speeding Boeing 767. The correct factor was 0.80 kg/liter, which meant they only had (7682)(0.803) = 6,669 kg of fuel on board. But if that was really the case, how had the plane flown from Toronto to Edmonton to Ottawa to Montreal with no working fuel gauges, as he incorrectly believed it had done? Informing Quintal that he was going to slip it, Pearson crossed his controls, steering hard right with the rudder and hard left with the ailerons. Everest can causes the world's most experienced climbers a difficult time for them to climb. People on the ground thus had no advance warning of the impromptu landing and little time to flee. I knew that was my call to board the plane. Notably, the RAT didnt power non-essential controls such as the flaps and slats, which increase lift and enable low-speed flight, so Pearson knew they would have to come in hot. The lack of hydraulic pressure prevented flap/slat extension which would have, under normal landing conditions, reduced the stall speed of the aircraft and increased the lift coefficient of the wings to allow the aircraft to be slowed for a safe landing. For whatever reason, this was causing the gauges to go blank when it should not have affected their operation. In 1983, there was no prescribed procedure for flying and landing without any engines. In the meantime, C-GAUN continued to fly with its own malfunctioning processor. The pilots immediately made their decision and reported it to ATC: flight 143 was diverting to Gimli.

Recognizing that he was facing a serious emergency, Captain Pearson immediately decided to divert to the nearest major airport. On previous aircraft types, manual fuel calculations were the explicit responsibility of the flight engineer. I would give them an award for outstanding stick and rudder skills but then I would take away their licenses for very poor airmanship. As the gliding plane closed in on the decommissioned runway, the pilots noticed that there were two boys riding bicycles within 1,000 feet (300m) of the projected point of impact. Weirs shift ended at Montreals Dorval International Airport, and together with his First Officer, he walked out to the parking lot, where he met the incoming Captain Robert Bob Pearson, who was to take over flying C-GAUN for the rest of the afternoon. What he did not expect was that the RAT didnt provide power to the landing gear actuators either. They are saying, Bad business decisions can be seen throughout history; however none has stirred such controversy as the error made by Ford Motor Credit concerning the 1971 Ford Pinto. Simultaneously, however, the Senior Operations Engineer responsible for drawing up 767 maintenance procedures based his fuel-related decisions on the two-crew DC-9, where he believed fuel calculations were not the mechanics responsibility, but the pilots. Captain Pearson is now in charge and has the idea the, Both flight crew and ground maintenance personnel, along with several human errors are to blame. SEE MEL 28412.. Overview. As the aircrafts nose had collapsed onto the ground, its tail was elevated and there were some minor injuries when passengers exited the aircraft via the rear slides, which were not long enough to accommodate the increased height. As the aircraft slowed on approach to landing, the reduced power generated by theram air turbinerendered the aircraft increasingly difficult to control. Could it be possible that they deserved both their punishments and their awards? The problem is that both pilots were instrumental to the fact the airplane took off without enough fuel. The conversion factor to convert litres to kilograms is typically around .8. Using a table of figures provided to the maintenance personnel, this value could then be converted into a volume in liters, the unit used by the fuelers. They had half the fuel they needed. The cockpit was also crowded with a number of people during Captains departure preparations, which could have caused a major distraction(Williams, 2003, p. Cruising at 41,000 feet, conversing with an Air Canada engineer about the systems on the new 767, the pilots had no idea that they were minutes away from running dry. This was exactly what Pearson needed. Track planes in real-time on our flight tracker map and get up-to-date flight status & airport information. Air Canada Flight 143. To make matters worse, the lack of fuel necessarily precipitated a near-total loss of electrical power, which blanked out most of the pilots instruments. The fourth one died because he fell trying to help others achieve their goal. All three fuel gauges operated normally. Meanwhile, a ground engineer, Jean Ouellet, was sent by Air Canada dispatch to perform the fuel drip test before C-GAUNs next scheduled departure. During the flight, the management computer indicated that there was still sufficient fuel for the flight, but only because the initial fuel load had been incorrectly entered: the fuel had been calculated in pounds instead of kilograms by the ground crew, and the erroneous calculation had been approved by the flight crew. Everything except the 767s had fuel gauges which read in pounds, and the drip sticks on other Air Canada planes variously read in inches, US gallons, and Imperial gallons, depending on the aircraft type. It was a story which seemed to be Hollywood-ready, with so many grandiose details and twists of fate and fortune that it in fact made for rather campy, melodramatic cinema, as moviegoers discovered when the events of flight 143 were adapted to the silver screen in 1995. When flight crew and pilots do their jobs correctly, Air accidents are much less likely to occur., I woke up with a loud scream which took over the silence that filled my room. On June 2, 1983, the aircraft developed an in-flight fire behind the washroom that spread between the outer skin and the inner dcor panels, filling the plane with noxious, toxic smoke. This caused them to arrive at a required additional fuel load half the size of what was actually needed, which they then divided by the wrong conversion factor again, compounding the mistake a second time. The flight management computer indicated that there was still sufficient fuel for the flight; but the initial fuel load had been measured in pounds instead of kilograms. These gauges are operated by a digital fuel gauge processor which has two channels. Here is an example of how the cause of a mishap can be obscured by press coverage, a good pilot's union, and a public's need for a hero now and then. As for the pilots, both learned valuable lessons and got on with their lives. With this kind of problem an aircraft can only be dispatched after compliance with the conditions of the Minimum Equipment List (MEL). Round-trip. Air Canada Flight 143 came to a final stop on the ground 17 minutes after running out of fuel. Nevertheless, Conrad Yaremko, the technician in Edmonton, had seen this type of failure before, on an Air Canada 767 two weeks earlier, on July 5th, and he remembered what he had done to fix it. The crew of flight 143, on the other hand, were unlucky enough to get fuelers in both Montreal and Ottawa who were unaware of the distinction, and provided the conversion factor for pounds instead. Tess joins in and the two discuss Flight 143, aviation accident categories, "flights to nowhere" and touch upon a few stories from the world of airline news. Fortunately for all concerned, one of [the captain's] skills is gliding. 1 Passenger. In Lockwoods view, the plane ran out of fuel because three layers of redundant safety features all failed, one after another: first the fuel gauges, then the requirement not to dispatch without working fuel gauges, and finally the direct check of the fuel quantity, prescribed by the MEL. This helped to slow the airplane and avoid injuring the people on the ground. The flight crew suffered from spatial disorientation . In the end, he declined to do so, but he did take the time to point out that serious mistakes were made prior to the departure of flight 143, and in fact most of his final report was spent discussing these, with only cursory detail afforded to the events of the flight itself. In this part of the country, that could only be Winnipeg other options were decidedly limited, given that the terrain underneath the plane consisted of empty Canadian Shield, followed by the mighty expanse of Lake Winnipeg, neither of which offered much in the way of airports or runways. Without it, the pilots would be unable to move the 767s massive control surfaces. Even today, Gimli Glider enthusiasts and there are many can own a piece of the legendary aircraft in the form of a luggage tag made from its fuselage skin. them to climb up. Next, less severe personal injuries can also occur due to falling of luggage. The reference to MEL 28412 invoked the relevant chapter of the planes Minimum Equipment List, or MEL a document kept aboard the aircraft which lists the systems which must be operable in order to depart, and provides instructions for additional safety measures to be taken when certain systems are not working. 01:13:00 - Michael continues his interview with Captain Bob Pearson and Pearl Dion. The two ground engineers, Jean Ouellet and Rodrigue Bourbeau, then consulted the conversion table and arrived at figures of 3,924 and 3,758 liters for the two tanks, adding up a total of 7,682 liters of fuel on board the plane. Then, within seconds, the left engine failed and the pilots began preparing for a single-engine landing. Air Canada could easily have ensured that its maintenance personnel were equally well trained, but the airline failed to do so. Although air travel is one of the safest forms of transportation, accidents do happen with dramatic and terrifying results. The use of the wrong conversion factor occurred without anyone ever being particularly confused about units. Back in the cockpit, the pilots made their final adjustments for the imminent emergency landing.
