About 40% of MAX fleet now grounded-but not by FAA
March 12, 2019, © Leeham News: About 40% of the world’s in-service Boeing 737 MAX fleet were grounded by the end of yesterday, Seattle time, after more governments and airlines banned operations.
Singapore was the latest to ban MAX operations from its air space.
The US Federal Aviation Administration said yesterday there isn’t enough information yet from the Ethiopian Airlines crash Sunday to conclude a grounding order is necessary.
But it added that it will issue an order for a mandatory action by April to make improvements to the flight control system. Boeing late Monday confirmed a software upgrade is in the works for its MCAS stall recovery system used on the MAX.
LNA reported early Monday that a plan to implement a software upgrade following the October crash of a Lion Air MAX 8 had not been implemented.

Indonesia grounds MAX, one-third of world fleet now grounded
Update: Royal Air Maroc, Mongolian Airlines ground MAX.
March 11, 2019, © Leeham News: Indonesia regulators today joined China, Grand Cayman Airways and Ethiopian Airlines in grounding the Boeing 737 MAX pending investigations or inspections.
This means about one third of the in-service MAXes have been grounded by regulators or
operators.
The moves came within 36 hours of the crash of Ethiopian Flight 302, a MAX 8, six minutes after take off from Addis Ababa. The crash killed all 157 people on board five months after a Lion Air 737-8 crash that killed 189 passengers and crew. Lion Air is an Indonesian carrier. The airline’s JT610 crashed 12 minutes after take off.
Digital transformation critical to Boeing
Subscription Required
Introduction
March 11, 2019, © Leeham News: Digital transformation is critical to Boeing’s evolving business model. But suppliers are in no rush to hand over their data to Boeing.
For more than a year, the airplane maker has been moving toward a new system for managing inventory and parts. As LNA noted last year, Boeing 
Commercial Airplanes’ management expects the new system, known as SAP, will streamline parts delivery and cut costs for Boeing and suppliers. BCA has been pushing suppliers for more transparency of their own supply chains and production flows. It likely would not surprise many industry watchers if BCA moves to integrate its suppliers into SAP in some fashion down the road.
Managers and executives at several suppliers told LNA that they expect Boeing to push for greater access to their companies’ internal data in coming years. They expressed ambivalence between potential efficiency gains and loss of autonomy.
Pontifications: Delays, design creep, cost overruns–nope, it’s not an airplane program
By Scott Hamilton
March 11, 2019, © Leeham News: It’s late. There have been creeping delays. There’s been design creep. There were unknown unknowns. It’s way over budget.
No, it’s not a new airplane program, though the parallels are quite apparent.
It’s our new house.
After a three year process, including changing builders, going through the city twice, hitting expensive unknowns and facing rising costs, today is finally, finally, moving day.
It’s been a horrible experience I wouldn’t wish on anyone.
This will sound familiar to Airbus, Boeing, Bombardier, Mitsubishi, Rolls-Royce, Pratt & Whitney and, to a lesser extent, GE and CFM. Only Embraer can say it finished on time and on budget.
Collins contract vote keeps 737 landing gear on track
By Bryan Corliss
March 11, 2019 (c) Leeham News: Workers at the Collins Aerospace landing gear plant in Everett, WA, have approved their first union contract with the company.
Both sides can come away feeling OK with how they did at the bargaining table. But the biggest winner in these talks actually was Boeing, which now doesn’t have to worry about a break in the flow of 737 landing gear for the next 40 months.
Boeing postpones public events for 777X roll-out
March 10, 2018, (c) Leeham News: Boeing today postponed the public ceremonies planned for Wednesday for the roll-out of the 777X, following the crash of Ethiopian Airlines Flight 302, a Boeing 737-8.
No date has been rescheduled.
Use caution about Ethiopian 737-8 crash/Update: China, airline ground Max
UPDATE, 4:30pm PDT: China and Grand Cayman Airlines have ground the 737 MAX. Developing.
UPDATE, 6:45pm PDT: China CAAC to review grounding order on their Monday, March 11, for further action.
March 10, 2019 (c) Leeham News: The crash today of an Ethiopian Airlines Boeing 737-8 MAX is raising more intense questions–and speculation–than usual after a crash because it comes in the wake of the Lion Air 737-8 crash last year.
But be cautious about drawing conclusions at this stage. Until the black boxes are recovered, information is limited.
Dominic Gates of The Seattle Times has about as comprehensive a wrap up at this stage on the available information here.
It should be noted that Ethiopian is considered one of the best airlines in the world and the best in Africa. It’s got a good safety record and service is considered very good. This is in contrast to the spotty safety record of Lion Air.
Below are factors investigators will consider:
Bjorn’s Corner: Yaw stability, Part 3.
By Bjorn Fehrm
March 08, 2019, ©. Leeham News: Yaw stability, which we discussed last week, has in itself no tricky dynamic problems. It’s a matter of making the vertical stabilizer large enough to have enough weathercock moment on the aircraft.
The tricky stuff comes through the interaction of yaw stability and roll stability.

Boeing’s 777X analyzed, Part 4

Introduction
March 07, 2019, © Leeham News: In our analysis series about the Boeing 777X, it’s time to look at the performance of the 777-9 and 777-8 and compared them to their main competitor, the Airbus A350-1000.
Figure 1. First flight test Boeing 777-9 with the GE9X engines mounted. Official roll-out is set for March 13th. Source: Boeing.
Summary:
- The 777-9 is a larger and heavier aircraft than the A350-1000. Its wide wing and efficient engines compensate the added weight when compared with the A350-1000. Both have best-in-class fuel efficiencies.
- The “cut and shut” 777-8 has the same capacity as the A350-1000. Here the wings, engines and empennage from the 777-9 give it Ultra Long Haul capabilities. In normal route use, this capability weighs on its fuel efficiency.
Boeing strikes new pay deal with Machinists
By Bryan Corliss
March 4, 2019, © Leeham News: Boeing and the Machinists Union have come to terms on a deal that will raise wages for the company’s hourly work force and help the company compete for workers in a tight Puget Sound labor market.
The two sides have agreed on a pact that raises new-hire pay by $4 an hour in all job classifications, and raises pay for experienced workers in 32 specific job classifications by as much as $10 an hour.
In all, as many as 16,000 people are getting raises at Boeing, which is about 55% of the IAM-represented work force.
“Not everybody is getting something here, and that’s hard,” said IAM 751 President Jon Holden in an interview with LNA. “But we were using whatever leverage we could to make some improvement.”
In a statement, Boeing said it is “committed to pay that is competitive within the local marketplace.”
