MAX-7

It was announced in Apr 2016 that the 737 MAX-7 would be stretched by two seat rows some two years before the first one was built. This was because sales of the 737 MAX-7 were very slow, winning just 60 orders. Boeing were considering cancelling the series. Instead, they redesigned it in a similar vein to the way the 737-900ER was redesigned to boost the failing 737-900. The only difference being that this was done before product launch.

The underlying problem with short versions of airliners is that they have proportionally more weight per seat than longer versions, ie more fuel burn with less potential for yield. If you look back at all generations of the 737 the shortest models have been the least successful:

  • 737-100. 30 sold out of 1144 originals; 2.6%
  • 737-500. 389 sold out of 1988 classics; 19.6%
  • 737-600. 69 sold out of approx 7100 NGs; 1.0%
  • 737-MAX7. 63 sold out of approx. 3600 MAXs; 1.7%

So Boeing has positioned this as the long range MAX, less fuselage length and pax means less weight and with the -8 strength it can still lift a lot of weight, ie fuel.

The 737 MAX-7 seating capacity is now 153 in two class configs or 172 pax in high density config, with a 76in (1.93m) fuselage stretch. The range is 3825nm by using stronger MAX-8 wings and landing gear, making it the longest range MAX.

Boeing says the MAX-7 carries 12 more passengers 400 nautical miles further and with “7% lower operating costs per seat than the A319NEO.

The first flight of the MAX 7 was on 16 March 2018 with N7201S (42561). It was flown by Boeing Test and Evaluation captains Jim Webb and Keith Otsuka from Renton to Boeing Field and lasted 3 hours and 5 mins.

Keith Leverkuhn, vice president and general manager 737 MAX programme, commented: “Everything we saw during today’s flight shows that the MAX 7 is performing exactly as designed. I know our airline customers are going to enjoy the capabilities this aeroplane will bring to their fleets.”

Summary of changes

  1. Fuselage lengthened by 76in (1.93m) to accommodate two seat rows (12 seats). Achieved by a 1.17m (46in) fuselage plug forward of the wing and a 0.76m fuselage plug aft of the wing.
  2. Two overwing exits on each side of the fuselage like the MAX-8 and MAX-9 to increase maximum certified passenger capacity.
  3. Higher gauge aluminium wing (like on -8 and -9) to allow for increased fuel capacity
  4. The maximum take-off weight increased from 70,300kg (155,000lb) to 80,300kg
  5. Strengthened landing gear of the 737-8 to take the higher weights
