Returning the MAX to service
Subscription Required
Introduction
April 1, 2019, © Leeham News: Returning the Boeing 737 MAX to services following its grounding should reasonably be a straight-forward affair, if past groundings were examples.
But, to mix a metaphor, there are plenty of unchartered waters with this grounding that stand ready to complicate matters.
Bloomberg reported Saturday that Europe’s FAA equivalent, EASA, skipped last week’s Boeing meeting of 200 pilots and regulators.
Summary:
- US FAA is no longer the leader or gold standard.
- EASA, Transport Canada want their own reviews.
- China, the first to ground the MAX, also suspended plane-by-plane certification.
Pontifications: I don’t know what to make of this
By Scott Hamilton
April 1, 2019, © Leeham News: One can’t help but think, a lot, about the two Boeing 737 MAX crashes and the facts that Boeing created the system, linked it to one sensor, not two, didn’t tell the airlines pilots about it, didn’t include it in pilot manuals, didn’t have a safety alert system as standard equipment, initially blamed the Lion Air pilots and reportedly lobbied Donald Trump not to ground the airplanes.
But my thoughts haven’t stopped here.

March 23, 2019, ©. Leeham News: Boeing this week presented how they plan to get the 737 MAX back in the air again. MCAS has a fix.
We look at what the fix tells us about the first implementation and the rationale behind its implementation.

WTO appeals court rules against Boeing; Airbus claims minimum $15bn in harm
March 28, 2019, © Leeham News: The World Trade Organization appeals panel today upheld European claims that Boeing received billions of dollars in illegal tax breaks and subsidies from the US Department of Defense, Washington State, Kansas and South Carolina.
From a previous set of rulings, the WTO also agreed that the US and Boeing failed to cure illegal tax breaks used under a federal program called Foreign Sales Corporations of FSC (pronounced fisk) dating to before 2006.
The adverse decision comes at a time when Boeing is on the defensive over two fatal accidents of its 737 MAX program and criticism over the development and approval of the MCAS stall recovery system believed by some to be at the heart of two crashes.
MCAS upgrade requires half-hour of pilot training

Introduction
March 28, 2019, © Leeham News: Boeing 737 MAX pilots learning about the revised software upgrade to the Maneuvering Characteristics Augmentation System (MCAS) will need a half hour of computer-based training (CBT), the company told the media yesterday in a briefing.
Pilots of the 737 NG who have not yet made the transition to the MAX also have to be trained on the MCAS now. Boeing did not specify if this will take longer than those already trained on the MAX.

Summary
- No estimate to MAX return to service.
- Waiting for investigations of the crashes.

The first electric-powered flight – in a six-passenger Beaver – will take place before the end of 2019, according to MagniX CEO Roei Ganzarski. MagniX and the Vancouver-based airline plan to pursue a supplemental type certificate for the planes, with a goal of 2021 for EIS.
Modifications will take place at a plant in Vancouver, a spokeswoman said.
Summary
- Overcoming skepticism.
- Tested engine, proven airframe.
- Short-haul routes.
Pontifications: Boeing NewCo exec, Slattery, faces challenges

Congestion costs billions, but airlines show little concern
Subscription required
Introduction
March 21, 2019, © Leeham News: There are many estimates for how much flight delays and disruptions cost airlines and passengers. But everyone agrees the total number is big—possibly more than $1bn for each major US airline each year.
In 2017, delays cost airlines and passengers $26.6bn, according to the FAA/Nextor estimate. That total includes direct cost to airlines and travelers, lost demand and indirect costs. Congestion at the three major airports serving New York City directly cost air carriers an estimated $834m a year, according to a 2009 report.

Yet despite the high cost, flight on-time statistics are basically where they were 20 years ago. Moreover, there are no discernible positive trends in the data collected by the U.S. Bureau of Transportation Statistics.
Of course, airlines take steps to decrease or limit flight delays, and, of course, some things, such as severe weather, are out of anyone’s control.
At the same time, airlines have shown little interest in pushing for low-cost solutions to decreasing system-wide congestion. There is no clear or easy explanations for carrier’s lack of motivation. However, interviews with current and former airline executives, researchers and others highlighted a few key factors.
Summary
- Reducing air traffic congestion is a huge, hairy beast of a problem.
- That complexity makes it difficult to see system-based approaches.
- Airlines are concerned that competitors could benefit more from reduced congestion.
