The -300ER, which combined the -300's added capacity with the -200ER's range, became the top-selling 777 variant in the late 2000s, benefitting as airlines replaced comparable four-engine models with twinjets for their lower operating costs. 717, 727, 737, 747, 757,  By 2004, the airliner accounted for the bulk of wide-body revenues for the Boeing Commercial Airplanes division. The loss of engine control was due to a fuel system blockage caused by ice that formed in the fuel system.  Rolls-Royce was also studying a Trent 8102 over 445 kN (100,000 lbf). 767, 777, 787, Related information  The trijet 777 was later dropped, following marketing studies that favored the 757 and 767 variants. General Electric improved the fan module and the high-pressure compressor stage-1 blisk in the GE-90-115 turbofan, as well as reduced clearances between the tips of the turbine blades and the shroud during cruise.  The 777-8 provides seating for 384 passengers and has a range of 8,730 nmi (16,170 km) while the 777-9 has seating for 426 passengers and a range of over 7,285 nmi (13,500 km).  FAA and EASA type certification for the freighter was received on February 6, 2009, and the first delivery to launch customer Air France took place on February 19, 2009. , Due to the impact of the COVID-19 pandemic on aviation, demand for new jets was reduced in 2020 and Boeing cut its monthly production from five to two 777s.  A U.S. House investigative report into two Boeing 737 Max crashes that killed 346 people blamed the plane manufacturer and the Federal Aviation … On Wednesday, a Boeing 777-300 operating as Emirates flight EK521 crash landed and burst into flames at Dubai International Airport after declaring an emergency.  The cabin also features "Flexibility Zones", which entails deliberate placement of water, electrical, pneumatic, and other connection points throughout the interior space, allowing airlines to move seats, galleys, and lavatories quickly and more easily when adjusting cabin arrangements. , The 777X is to feature new GE9X engines and new composite wings with folding wingtips. Versions of the 777 have been acquired by government and private customers. Two passengers, who had not been wearing their seatbelts, were ejected from the aircraft during the crash and were killed.  It was delivered first to British Airways on February 6, 1997.  The competing Airbus aircraft was the A330-300.  , On February 29, 2000, Boeing launched its next-generation twinjet program, initially called 777-X, and began issuing offers to airlines. 17 January 2008; British Airways 777-200ER; G-YMMM; flight 38; London, England:  The fly-by-wire system also incorporates flight envelope protection, a system that guides pilot inputs within a computer-calculated framework of operating parameters, acting to prevent stalls, overspeeds, and excessively stressful maneuvers.  The aircraft, operated by British Airways, suffered fire damage to the lower wing panels and engine housing; it was later repaired and returned to service.  However, the -100X would have carried fewer passengers than the -200 while having similar operating costs, leading to a higher cost per seat. Boeing stated that every 1% improvement in the 777-300ER's fuel burn translates into being able to fly the aircraft another 75 nmi (139 km; 86 mi) on the same load of fuel, or add ten passengers or 2,400 lb (1,100 kg) of cargo to a "load limited" flight. While the 300 people onboard the wide-body evacuated alive, a firefighter was killed when tackling the fire. Its operating empty weight with Rolls-Royce engines in typical tri-class layout is 343,300 lb (155.72 t) compared to 307,300 lb (139.38 t) for a similarly configured -200.  The 1.37 m (4 ft 6 in) wider wing was to be strengthened and the fuel capacity enlarged, and it was to be powered by simple derivatives with similar fans. , Boeing introduced a number of advanced technologies with the 777 design, including fully digital fly-by-wire controls, fully software-configurable avionics, Honeywell LCD glass cockpit flight displays, and the first use of a fiber optic avionics network on a commercial airliner.  New production methodologies were developed, including a turn machine that could rotate fuselage subassemblies 180 degrees, giving workers access to upper body sections.  Its wings have an aspect ratio of 9.0. It initially competed with Airbus A340 and McDonnell Douglas MD-11, both now out of production, and currently competes with the Airbus A330-300 and newer Airbus A350 XWB.  At 242.4 ft (73.9 m) in length, the -300 became the longest airliner yet produced (until the A340-600), and had a 20 percent greater overall capacity than the standard length model. , From the program's start, Boeing had considered building ultra-long-range variants.  Each manufacturer agreed to develop an engine in the 77,000 lbf (340 kN) and higher thrust class (a measure of jet engine output) for the world's largest twinjet. The United States, usually the leader in aviation safety, had been a notable holdout. , Since its launch, the -300ER has been a primary driver of the twinjet's sales past the rival A330/340 series. Large folding wingtips, 21 feet (6.40 m) long, were offered when the 777 was first launched, to appeal to airlines who might use gates made to accommodate smaller aircraft, but no airline purchased this option. The 777 is a low-wing, 31,000 US gal / 117,340 L / 207,700 lb / 94,240 kg, 47,890 US gal / 181,283 L / 320,863 lb / 145,538 kg. Boeing was also redesigning the inboard flap fairings to reduce drag by reducing pressure on the underside of the wing. As of July 2020 , the 777 has been involved in 29 aviation accidents and incidents, including a total of eight hull losses (five in-flight and three on-ground incidents), resulting in 541 fatalities along with three hijackings.  Boeing was expected to drop 777 production to five per month in August 2017.  After the search for the aircraft began, Malaysia's prime minister announced on March 24, 2014 that after analysis of new satellite data it was now to be assumed "beyond reasonable doubt" that the aircraft had crashed in the Indian Ocean and there were no survivors. By the mid-2010s, the 777 had become prevalent on the longest flights internationally and had become the most widely used airliner for transpacific routes, with variants of the type operating over half of all scheduled flights and with the majority of transpacific carriers. Both crashed jets were Boeing 737 Max 8s, a variant of the best-selling aircraft in history.  The Signature Interior has since been adapted for other Boeing wide-body and narrow-body aircraft, including 737NG, 747-400, 757-300, and newer 767 models, including all 767-400ER models. The aircraft sustained heat damage and was written off. The outboard raked wingtip was to have a divergent trailing edge, described as a "poor man's airfoil" by Boeing; this was originally developed for the McDonnell Douglas MD-12 project.  The last Boeing 777 to crash was a British Airways jet en route from Beijing to London's Heathrow airport, which crash landed short of the runway in …  The initial proposal featured a longer fuselage and larger wings than the existing 767, along with winglets.  The official accident investigation concluded in June 2014 that the pilots committed 20 to 30 minor to significant errors in their final approach, and that complexities of the automated controls contributed to the accident. Other notations include "773ER" and "773B" for the -300ER. During final approach to London's Heathrow, the aircraft engines from Beijing, China, at 720 feet  This lets engineers assemble a virtual aircraft, in simulation, to check for interference and verify that the thousands of parts fit properly—thus reducing costly rework. Aviation Week & Space Technology, February 16 – March 1, 2015, pp. The projected operational empty weight is 168,560 kg (371,610 lb) in airline configuration, at a weight of 216,370 kg (477,010 lb) and FL350, total fuel flow is 6,790 kg/h (14,960 lb/h) at M0.84/472 kn (874 km/h), rising to 8,890 kg (19,600 lb)/h at M0.87/506 kn (937 km/h).  By March 2018, the 777 had become the most-produced Boeing wide-body jet, surpassing the Boeing 747. In January 2016, Boeing confirmed plans to reduce the production rate of the 777 family from 8.3 per month to 7 per month in 2017 to help close the production gap between the 777 and 777X created by a lack of new orders.  US officials believe the most likely explanation to be that someone in the cockpit of Flight 370 re-programmed the aircraft's autopilot to travel south across the Indian Ocean.  Nine aircraft fitted with General Electric, Pratt & Whitney, and Rolls-Royce engines were flight tested at locations ranging from the desert airfield at Edwards Air Force Base in California to frigid conditions in Alaska, mainly Fairbanks International Airport. , The converted aircraft has a maximum payload of 224,000 lb (101.6 t), a range of 4,500 nmi (8,300 km) and shares the door aperture and aft position of the 777F.  It has a maximum design range of 8,555 nautical miles (15,844 km) as of 2017[update]. , Initially second to the 747 as Boeing's most profitable jetliner, the 777 became the company's most lucrative model in the 2000s. The main fuselage cross-section is circular and tapers rearward into a blade-shaped tail cone with a port-facing auxiliary power unit.  Both models were to be equipped with new generation GE9X engines and feature new composite wings with folding wingtips.  This system can be overridden by the pilot if deemed necessary.  Elements made from composite material include the cabin floor and rudder.  The official accident report, released in October 2015, states that airliner was brought down by a Buk missile launched from territory held by pro-Russian separatists.  In 2010, the variant further received a 5,000 lb (2,300 kg) maximum zero-fuel weight increase, equivalent to a higher payload of 20–25 passengers; its GE90-115B1 engines received a 1–2.5 percent thrust enhancement for increased takeoff weights at higher-altitude airports. , Air France has a 777-300ER sub-fleet with 472 seats each, more than any other international 777, to achieve a cost per available seat kilometer (CASK) around €.05, similar to Level’s 314-seat Airbus A330-200, its benchmark for low-cost, long-haul.  It holds the world record for the longest nonstop flight by a commercial airliner.  Later plans expanded the fuselage cross-section but retained the existing 767 flight deck, nose, and other elements.  Initial service was affected by gearbox bearing wear issues, which caused British Airways to temporarily withdraw its 777 fleet from transatlantic service in 1997, returning to full service later that year. The prototype was rolled out on April 9, 1994, and first flew on June 12, 1994.  The fly-by-wire system is supplemented by mechanical backup.  The first delivery to Air France took place on April 29, 2004. Although the aircraft experienced significant fire and heat damage, none of the ten crew members or 307 passenges were killed.  The wings also serve as fuel storage, with longer-range models able to carry up to 47,890 US gallons (181,300 L) of fuel.  By February 2015, the backlog of undelivered 777s totaled 278 aircraft, representing just under three years of current production at 8.3 aircraft per month, causing Boeing to ponder the 2018-2020 time frame. The original 777 with a maximum takeoff weight (MTOW) of 545,000–660,000 lb (247–299 t) was produced in two fuselage lengths: the initial -200 was followed by the extended-range 777-200ER in 1997; and the 33.25 ft (10.13 m) longer 777-300 in 1998. At this time, the position of the aircraft was estimated 90 NM northeast of … Other British Airways plane crashes , Launched at the Paris Air Show on June 26, 1995, its major assembly started in March 1997 and its body was joined on July 21, it was rolled-out on September 8 and made its first flight on October 16. In October, a Boeing 737 MAX 8 operated by Lion Air crashed minutes after taking off from Jakarta, Indonesia, killing all 189 passengers and crew. General Electric offered to develop the GE90-115B engine, while Rolls-Royce proposed developing the Trent 8104 engine. This was the first serious accident for the 777 since it began commercial service in 1995. Its higher MTOW and increased fuel capacity permits a maximum range of 7,370 nautical miles (13,650 km) with 396 passengers in a two-class seating arrangement. The 777X features composite wings with folding wingtips and General Electric GE9X engines. There were no passengers on either aircraft during the crash. Plane crash rates by model, Interview about a 2011 FAA directive that may be related to the engine failure.  The -300ER is the best-selling 777 variant, having surpassed the -200ER in orders in 2010 and deliveries in 2013. The following are significant events involving the aircraft model. , The production freighter model, the 777F, rolled out on May 23, 2008. As a consequence, the 777-300ER received an engine and aerodynamics improvement package for reduced drag and weight.  Lasting 22 hours and 42 minutes, the flight surpassed the -200LR's standard design range and was logged in the Guinness World Records.  The A-market would be covered by a 4,200 nmi (7,800 km) range, 234 t (516,000 lb) MTOW aircraft for 353 to 374 passengers powered by 316 kN (71,000 lbf) engines, followed by a 6,600 nmi (12,200 km) B-market range for 286 passengers in three-class, with 365 kN (82,000 lbf) unit thrust and 263 t (580,000 lb) of MTOW, an A340 competitor, basis of an A-market 409 to 434 passengers stretch, and eventually a 7,600 nmi (14,000 km) C-market with 400 kN (90,000 lbf) engines.  Thirty-three customers received 422 deliveries, with no unfilled orders as of April 2019[update]. Airline Incidents for aircraft type Boeing 777-300 Home > Incidents and Accidents > Boeing 777-300 AeroInside has currently 317 articles listed involving a Boeing 777-300.  The 777 "was completed with such precision that it was the first Boeing jet that didn’t need its kinks worked out on an expensive physical mock-up plane", which contrasted sharply with the development of Boeing's next new airliner, the 787. Troubled US air manufacturer Boeing celebrates a badly needed success with the maiden flight of its delayed 777-9X, the world's longest and largest twin-engine airliner. By January 1999, its MTOW grew to 340,500 kg (750,000 lb), and thrust requirements increased to 110,000–114,000 lbf (490–510 kN). The U.S. Federal Aviation Administration publicly affirmed the airw  In 2018, assembling test 777-9 aircraft was expected to lower output to an effective rate of 5.5 per month. British Airways Flight 38 was a scheduled international passenger flight from Beijing Capital International Airport in Beijing, China to London Heathrow Airport in London, United Kingdom.On 17 January 2008, the Boeing 777-200ER aircraft operating the flight crashed just …  In November 2011, assembly began on the 1,000th 777, a -300ER model for Emirates, which was rolled out in March 2012.  The 777-300ER features raked and extended wingtips, a strengthened fuselage and wings and a modified main landing gear. , In the 2000s, Boeing began studying the conversion of 777-200ER and -200 passenger airliners into freighters, under the name 777 BCF (Boeing Converted Freighter). Reportedly, the 777 could eventually be replaced by a new aircraft family, Yellowstone 3, which would draw upon technologies from the 787. , The first hull loss occurred on January 17, 2008, when a 777-200ER with Rolls-Royce Trent 895 engines, flying from Beijing to London as British Airways Flight 38, crash-landed approximately 1,000 feet (300 m) short of Heathrow Airport's runway 27L and slid onto the runway's threshold. , The 777-300ER ("ER" for Extended Range) is the B-market version of the -300. Another change involved elevator trim bias. The pilots initiated a go-around procedure shortly after the main wheels touched-down onto the runway, however, the aircraft settled back onto the ground apparently due to late throttle application.  The aircraft also features the largest landing gear and the biggest tires ever used in a commercial jetliner. , The first generation of Boeing 777 models, the -200, -200ER, and -300 have since been known collectively as Boeing 777 Classics. The plane type Boeing 777-300 is also known as ICAO type designator B773 and features 2 engines.  The aircraft sustained structural-, heat- and smoke damage, and was written off.  The design phase for the new twinjet was different from Boeing's previous commercial jetliners.  In 1978, Boeing unveiled three new models: the twin-engine Boeing 757 to replace its 727, the twin-engine 767 to challenge the Airbus A300, and a trijet 777 concept to compete with the DC-10 and L-1011.  United required that the new aircraft be capable of flying three different routes: Chicago to Hawaii, Chicago to Europe, and non-stop from Denver, a hot and high airport, to Hawaii. Other Boeing Models: 717, 727, 737 747, 757, 767, 777, 787. Immediately after the accident, which happened in 2016, a landing gear failure was suspected to be at fault.  At its peak, a new 777-300ER was valued US$150 million, falling to US$17 million in 2019. Within the 811 777-300ERs delivered and 33 to be delivered by October 2019, GE Capital Aviation Services (GECAS) anticipates up to 150-175 orders through 2030, the four to five months conversion costing around $35m.
