Boeing says the two largest variants of its 737 MAX program are expected to comprise up to a quarter of total sales as the MAX 9 begins its flight test program.

The MAX 9, a stretch of the 737 MAX 8, took off on its maiden flight from Renton Field in Washington State at 1052 on Friday (US time) and landed at Seattle’s Boeing Field 2 hours and 42 minutes later at 1334.

Boeing said in a statement the first flight tested the aircraft’s flight controls, systems and handling qualities, with Captain Christine Walsh and Captain Ed Wilson at the controls.

First delivery is expected in 2018.

Powered by two CFM International LEAP-1B engines, the MAX 9 has been designed with a maximum range of 3,515nm for up to 220 passengers in a single-class or 178 passengers in a two-class configuration, according to Boeing figures.

Boeing also published a video of the first flight of N7379E on its YouTube channel:


Boeing is currently offering four variants of the 737 MAX, which as well as the new generation engines feature a new flightdeck, fly-by-wire spoilers and new technology winglets compared with the current model 737 NG. To accommodate the LEAP 1B’s 176cm fan diameter, compared with the CFM56’s 155cm diameter fan on the NGs, the 737 MAX also features a taller nose wheel landing gear leg, while the engine nacelles’ trailing edges feature noise-reducing chevron shaping, as on the 787.

The MAX 8, which at 3,515nm range with 162 passengers in a two-class configuration Boeing describes as the “heart of the market”, has been certified and is due for first delivery to US-based Southwest Airlines in May.

The company is also developing the 200-seat MAX 200, which uses the same fuselage as the MAX 8 but trades reduced range for more seats. Ryanair is the launch customer.

The smallest variant, the MAX 7, has been designed to carry 138 passengers in a two-class layout 3,825nm. Assembly of the first aircraft is expected in the final quarter of calendar 2017, with first flight in the first quarter of calendar 2018, Teal said.

In early March, Boeing publicly unveiled a proposed MAX 10X, an aircraft that would be capable of accommodating 230 seats in a single-class layout or 189 seats in a two-class configuration.

The Boeing website lists 3,703 orders for its 737 MAX family of aircraft at the end of March 2017, without breaking the total down into individual variants.

By contrast, Airbus separates out its 5,056 A320neo family of aircraft orders into 55 A319neo, 3,616 A320neo and 1,385 A321neo variants.

Industry estimates suggest the A321neo was outselling the 737 MAX 9 by a factor of five to one.

However, chief project engineer and deputy program manager for the Boeing 737 MAX program Michael Teal told reporters during a dial-in briefing on Friday that market watchers needed to be “careful” with the order numbers.

“When it comes down to predicting the delivery streams, if you look at the deliveries out of the NG market today what are we delivering? We are delivering that 15-20 per cent in that larger market of the 900ERs. With that we expect the family to be very similar going forward,” Teal said.

“Now if you looked only at the orders, I think you have got to be careful. It’s around what we deliver.

“Many airlines order 8s with options for 9s and we don’t tell you about that. We just keep it, we just wait until the airline makes their decision so they have options.

“Our expectation is when the deliveries and the families are growing, we expect that that heart of the market remains as the 8, but that 9s and 10s are going to be between 15 and 25 per cent of that marketplace.”

While yet to be formally launched, Teal said the airframer was currently consulting with airlines about the level of interest in the MAX 10X, adding Boeing was targeting 2020 for first delivery.

“We are doing the product development trade studies right now, taking with customers,” Teal said.

“It’s offerable. It is going out to the customers. We are working with the customers today and really we will determine when we launch that program when the customers show the interest and they are ready to buy the program.

“Sales teams are out working with customers today.”

The 737 MAX 10X would be a 1.68m stretch of the MAX 9, with 1.17m forward of the wing and the remaining 50cm aft of the wing.

As a result, Boeing engineers are working on a larger landing gear to accommodate the additional length of the aircraft.

“We just need a little more extension of that gear to enable the same rotation margin on takeoff as well as the landing performance from a contact margin,” Teal explained.

“We’ve looked at several different design parameters. We are still in what I’ll call that design development.”

“I’ve seen several of our concepts that we are now putting into prototype testing. It’s looking really good and I don’t feel we’re going to have any real issues with it.”

“It’s just getting that final design done.”

The aircraft is expected to reach firm configuration at the 2017, Teal said, with first delivery targeted for 2020 should airlines be prepared to order the aircraft.

In this part of the world, Virgin Australia has ordered 40 737 MAX aircraft. The airline recently deferred first delivery “final quarter of the 2019 calendar year”, from 2018 previously.

Boeing’s other two 737 MAX customers in Oceania are Air Niugini, which put pen to paper in February 2016 for four MAX aircraft arriving from 2020, and Fiji Airways, which has five 737 MAX 8s slated for delivery from 2018.

Teal said production of current model 737 NGs was expected to end in mid-2019.

    Landing gear lengthening for the 10MAX…. This identifies an interesting conundrum…. how to make a B737MAX perform like a B757.

    Probably shows that the B752 design was well conceived in its day for its range/payload, and that with the B752 design Boeing designers definitely learned lessons about fuselage lengthening from the DC-8 (which was much more scale-able than the B707). (read Cilve Irving’s book WIDEBODY)

    Unfortunately the genetics of the B737 still lie around Jack Steiner’s 100/100/100 theory – 100ft long, 100 ft wingspan, and 100 seats powered by low-slung turbojets.

    No doubt that Boeing has been brilliantly innovative in re-creating the basic B737 into a bypass turbo-fan powered family of aircraft, but perhaps they should not ignore the reasons why their designers iterated and configured the B752 the way they did in the early 1980s.

    Australia probably didn’t need the B752 when it came along, but one gets the sense that the intercontinental range / medium payload design is possibly going to become a interesting market area in Australia. More pressure is coming onto local airlines to provide hub-busting and regional-city originating international services.

    I often wonder why Boeing didn’t revitalise the 757 design.

  • AlanH


    Yes indeed, the 757 was by far the better design for today’s market as it already had the taller undercarriage that would have easily accommodated the larger new gen bypass turbo-fan engines. The cabin width is the same as the 737 (both derived from the 707 series) but it already had the required length that the 737 is now being asked to stretch out to, and it was better balanced as a result. Doesn’t seem to make sense.

    BA had and I presume still has 757’s flying domestically in the UK. Often flew Manchester to Heathrow on their hourly shuttle flights, Nice planes, nicknamed the “Preying Mantis”.

    @ Charles

    No BA sold their B757’s years ago. The majority were bought by UPS or FEDEX I think.

    The market is looking for twin aisle.
    For faster on/offboarding.
    Combined with the long range of the 757.
    A twin aisle 797 carbon fibre fuselage is on the cards.

  • random



    The problem with twin aisle is that it envitably leads to an aircraft that is just too big for long-thin routes (6000-8000km) when the desirable aircraft pax load in this family of aircraft (with 2 class seating) is only 150-200.

    The only way to achieve twin aisle would be for manufacturers to explore a new fuselage width that sits between B737/A320 (12-13ft) and B767/A330 (16-17ft).

    The B767 width was originally chosen as a halfway point between B707 and B747, so in essence this would be a further compromise in width, which would probably yield a 2-2-2 seating arrangement (ie still 6 abreast, but with 2 aisles instead of 1).

    I’m not sure that either the manufacturers or airlines would really be keen on 6 abreast with 2 aisles, even with heavy use of composites to bring down weight.
