Boeing 787-8

role : wide-body long-range airliner

importance : ****

first flight : 15 December 2009 from Paine Field operational : October 2011 (ANA)

country : United States of America

ICAO aircraft type designator : B788

Program manager : Mike Bair (till October 2007)

production : 397 aircraft. Final assembly at Boeing South Carolina (North Charleston)

since March 2021, before at Everett). Mayor parts built by many subcontractors in

Japan (wings), Italy (horizontal tail, fuselage sections), India (floor beams), France

(doors) etc.

general information :

The 787 was designed for efficient point-to-point flights, a shift from hub-and-spoke

travel. Randy Baseler, Boeing Commercial Airplanes VP Marketing stated that

airport congestion comes from large numbers of regional jets and small single-aisle

airliners, flying to destinations where a 550-seat  Airbus A380 would be too large; to

reduce the number of departures, smaller airplanes can increase by 20% in size

and  airline hubs  can be avoided with  point-to-point transit

The 787 was the first airliner built mostly from composites. It makes greater use of

electric systems reducing hydraulic and pneumatic systems.

Airlines have the option to choose from two turbofan engines, the Rolls Royce Trent

1000 or the General Electric GEnx-1B. Boeing stated the 787 would be approximately

20 percent more fuel-efficient than the 767.

On April 26, 2004, Japanese airline All Nippon Airways (ANA) became the launch

customer for the 787, announcing a firm order for 50 aircraft with deliveries to begin

in late 2008. The first roll out was on 8 July 2007 but after that the program was

delayed several times, and only in December 2009 the first flight was made.

The first 20 built 787 were overweight, and were hard to sell, they were nicknamed

the “Terrible Teens”. From the start Boeing worked on a weight reduction program

and later built aircraft met the goals. The aircraft has a design life of 44,000 flight

cycles. In 2007 the list price of the 787-8 was around 160 mln USD.

On December 6, 2011, test aircraft ZA006 (sixth 787), powered by General Electric

GEnx engines, flew 10,710 nmi (19,830 km; 12,320 mi) non-stop from Boeing Field

eastward to  Shahjalal International Airport  in  Dhaka , Bangladesh, setting a new

world distance record for aircraft in the 787's weight class, which is between 440,000

and 550,000 lb (200 and 250 t). This flight surpassed the previous record of 9,127

nautical miles (16,903 km; 10,503 mi), set in 2002 by an  Airbus A330

After its first six months of service, Rolls-Royce powered ANA aircraft were burning

around 21% less fuel than the replaced 767-300ER on international flights, slightly

better than the 20% originally expected

Early 787 operations encountered several problems caused mainly by its

  lithium-ion batteries , including fires onboard some aircraft. In January 2013, the

U.S.  FAA  grounded all 787s until it approved the revised battery design in April 2013.

As of 24 March 2018, the 787's longest route is  Qantas ' Perth-London Heathrow, a

distance of 14,499 km (7,829 nmi; 9,009 mi)

Significant quality control issues from 2019 onward caused a production slowdown

and, from January 2021 until August 2022, an almost total cessation of deliveries.

Boeing has spent $32 billion on the program; estimates for the number of aircraft

sales needed to  break even  vary between 1,300 and 2,000. © extracts from Wikipedia

Boeing 787-8 drawing with location of composite structure

The 787 is the first commercial aircraft to have an airframe majority made of  carbon fiber reinforced polymer  (CFRP), applied in: the  empennage , fuselage, wings, doors, and in most other main components. Each 787 contains approximately 77,000 lb (35 t) of CFRP, made with 51,000 lb (23 t) of pure carbon fiber. CFRP materials have a higher  strength-to-weight ratio  than conventional aluminium structural materials, which contributes significantly to the 787's weight savings, as well as superior fatigue behaviour. Boeing lists its materials by weight as 50% composite, 20% aluminium, 15%  titanium , 10% steel, and 5% other materials.

JA804A All Nippon Airways Boeing 787-8 Dreamliner photographed at Hong Kong Chek Lap Kok (HKG / VHHH) by Yiran

Wednesday 16 January 2013 All Nippon Airways Boeing 787-8 JA804A c/n 34486

DSP Flight from Yamaguchi – Ube apt. (UBJ) (loc 33°55’48”N 131°16’36”E ) to Tokyo with 8 crew and 129 passengers. When climbing after take-off through 32000 ft a battery failure message came on accompanied by unusual smell in the cockpit. The airplane diverted to Takamatsu Airport (loc. 34°12’57”N 134°01’07”E ) where an emergency evacuation was executed. Although the main battery was damaged, it did not lead to a fire. Inspection revealed a battery fire. A similar incident in a parked  Japan Airlines  787 at  Boston 's  Logan International Airport  within the same week led the  Federal Aviation Administration  to ground all 787s.

First flight : December 2011. Airframe hrs : 2150 engines : RR Trent 1000. No people died in this incident, only 4 light injured during evacuation.

location : +-20km 34°02’37”N 132°43’13”E
