Accidents & Serious Incidents involving B77W

  • A320/B773, Dubai UAE, 2012 (On March 20 2012 a Ural Airlines Airbus A320 failed to taxi as instructed after vacating the landing runway 12L at Dubai and crossed the lit stop bar of an intersection access to runway 12R before stopping just in time to prevent a collision with a Boeing 777-300ER about to pass the intersection at very high speed on take off. Taxi clearance had been correctly given and acknowledged. The aircraft commander had extensive aircraft type experience but the inexperienced First Officer appeared to be undergoing early stage line training with a Safety Pilot present. The Investigation is continuing.)
  • B773, Lagos Nigeria, 2010 (On 11 Jan 2010, an Air France Boeing 777-300ER successfully rejected a night take off from Lagos from significantly above V1 when control column pressure at rotation was perceived as abnormal. The root and secondary causes of the incident were found to be the failure of the Captain to arm the A/T during flight deck preparation and his inappropriate response to this on the take off roll. It was considered that his performance may have being an indirect consequence of his decision to take a 40 minute period of in-seat rest during the 90 minute transit stop at Lagos.)
  • B773, vicinity Toronto Canada, 2012 (On 28 May 2012 a GE90-powered Air Canada Boeing 777-300ER experienced sudden failure of the right engine during the initial climb after take off. There were no indications of associated engine fire and the failed engine was secured, fuel jettisoned and a return to land made. The Investigation found that the failure was related to a known manufacturing defect which was being controlled by repetitive boroscope inspections, the most recent of which was suspected not to have identified deterioration in the affected part of the engine.)
  • B77W, en-route, northeast of Los Angeles USA, 2016 (On 16 December 2016, a Boeing 777-300 which had just departed from runway 07R at Los Angeles was radar vectored in Class ‘B’ airspace at up to 1600 feet below the applicable minimum radar vectoring altitude. The Investigation found that the area controller’s initial vectoring had been contrary to applicable procedures and their communication confusing and that they had failed to recover the situation before it became dangerous. As a result, as the crew were responding in night IMC to a resulting EGPWS ‘PULL UP’ Warning, the aircraft had passed within approximately 0.3 nm of obstructions at the same altitude.)
  • C525 / B773, vicinity London City UK, 2009 (On 27 July 2009, a Cessna 525 departing from London City failed to comply with the initial 3000 feet QNH SID Stop altitude and at 4000 feet QNH in day VMC came into close proximity on an almost reciprocal heading with a Boeing 777-300ER. The 777, on which line training was being conducted, failed to follow any of the three TCAS RAs generated. Actual minimum separation was approximately 0.5nm laterally and estimated at between 100 feet and 200 feet vertically. It was noted that the Cessna had been given a stepped climb SID.)

The Boeing 777 has been a staple in widebody transport since its first flight in 1994.

Since then, the 777 (also known as the B777 or the Triple Seven) has seen many variants developed from it.

The most numerous and successful variant of Triple Seven is the 777-300ER, also known by its ICAO designation as the B77W.

What is it that made the B77W so successful? Keep reading to find out 10 things you didn’t know about the B77W

10. It is the Most Numerous B777 Variant

The B77W variant of the 777 is the most common of its type, with 810 airframes delivered, and 34 more on order.

The first B77W was delivered to Air France on April 29, 2004, and is still under production.

9. It is Extremely Powerful

The B77W is powered by a pair of General Electric GE90-115B engines, each providing over 115,000lbs of thrust.

Next Generation Boeing Plane 797

The GE90-115B is the most powerful jet engine in the world.

8. It is the World’s Largest Twinjet

Due to the power provided from the GE90’s, it only requires two of them, making the B77W the world’s largest twin-engine aircraft.

Its direct competitor, the Airbus A350, is a twinjet, but has a maximum takeoff weight that is nearly 80,000lbs less than the B77W.

With a maximum takeoff weight of 775,000lbs, it’s also the heaviest variant of the 777 family.

7. It is Cost Efficient

It’s powerful and efficient engines provide cost savings for the airlines it serves.

Many airlines have replaced their older Boeing 747s with B77Ws because the latter is 20% more fuel efficient.

It is also more efficient and cheaper to operate than its Airbus competitors, the previously mentioned A350 and the 4 engine A340.

6. It Holds a Massive Amount of Fuel

About 40% of the B77W’s maximum takeoff weight consists of fuel.

Fully loaded, the B77W can hold nearly 48,000 gallons of jet fuel, the equivalent of 4 semi-truck tankers.

This gives it a range of over 7,000NM, making it a great choice for intercontinental travel.

5. Boeing is Developing a Freighter Version

Many wide-body aircraft are converted for use as freighter aircraft, and the B77W is no exception.

Boeing is developing an updated version of the Triple Seven, called the 777X, which will also feature a freighter variant.

The 777X will not be available until 2022, so Boeing has decided to convert some B77W airframes into freighters to bridge the gap.

4. It’s the “Air Force One” of Japan

In 2014, the government of Japan purchased two B77W aircraft to serve as the official air transport for the Prime Minister and the Emperor.

They officially entered service in 2019, replacing their old 747s.

3. It is Very Safe

The 777 fleet as a whole are among the safest planes to ever fly, with only 0.4% of the fleet being written off due to accident.

On June 27, 2016, a Singapore Airlines B77W took off from Changi en-route to Milan when a low oil alarm went off.

The crew turned around, and the engine caught fire as it landed back in Singapore. The plane landed safely, and there were no injuries.

2. It is the Aircraft of Choice for Emirates

Emirates, based out of Dubai, UAE, is the worlds largest operator of the B77W.

They currently have 130 B77W aircraft in service, the largest amount of aircraft in their inventory.

1. B77Ws Will Start to Retire

With the newer B777X coming in a few short years, many airlines will start retiring their B77W fleets.

The oldest B77W airframes are over 15 years old, and the high volume of use leads to wear and tear.

While most airlines are keeping a lid on retirement, Qatar Airways plans to retire 48 of their B77W’s by 2024 to be replaced by the B777X.
