I think he is right. The possibility that this rate hike will NOT be executed is higher than the possibility that we will really see the hike. Aboulafia points out several reasons why that is.
And there is another one (at least in my mind): and that is the fast pace that Boeing wants to transition from the B737NG to the B737MAX. The article by Dominic Gates points out that by 2018 when the rate hike would be kicking in the output of the B737MAX would reach 26 aircraft a month, thus 50% of the production. And another article at Flightglobal states that the last B737NG will be delivered to Ryanair in the second quarter of 2019. So the plan is to transition from the NG to the MAX in less than two years. This has two consequences:
- I often wrote about how many B737NG orders Boeing would need to fill the B737NG production slots until the B737MAX will take over full production. I assumed that the transition will take place in a similar manner than Airbus plans it for the A320. The hast A320ceo will be delivered in 2018, almost three years after the first delivery of the A320neo. Now if Boeing cuts the transition time to under two years, a lot less open B737NG production slots have to be filled. In a first guess I would say about 250.
- There is a big challenge for all B737MAX suppliers which have to produce parts that changed for the B737MAX compared to the B737NG design. The one supplier that will be most challenged is CFM (and CFM's suppliers as well). They have to handle the ramp up of the LEAP-1A for the A320neo and the LEAP-1B for the B737MAX almost simultaneously.
