Latest engine problem means NMA EIS slides

Introduction
April 22, 2019, © Leeham News: If there remains any doubt that Boeing’s prospective New Midmarket Airplane (NMA) won’t be ready for entry into service (EIS) by 2025, it should be dispelled by now.
The grounding of the 737 MAX March 13, which is likely to continue well into the summer, will delay any launch of the program—should Boeing proceed.
The Board of Directors is unlikely to approve Authority to Offer (ATO) the NMA for sale as long as the cash flow for the MAX is outgoing and not in-coming.
Although this has its own impact on the NMA timing, it’s not the critical factor.
Last week, it was revealed that the CFM LEAP engine on the MAX (and the Airbus A321neo) has a problem called coking, which led to the contained engine failure of a Southwest Airlines MAX being ferried from Orlando (FL) to Victorville (CA) for the grounding of the Boeing airplane (see here and here). It’s the latest in a long line of engine maker problems with their current generation of powerplants.
This issue is unrelated to the MAX MCAS grounding. It also affects some engines on the A320neo family.

Pontifications: Collins Aerospace resolved to compete for aftermarket services
By Scott Hamilton
April 22, 2019, © Leeham News: Moves by Airbus, Boeing and Embraer to increase their shares of aftermarket services are viewed by their own suppliers with a mix of trepidation or resolve, depending on who they are.
For Collins Aerospace, it’s resolve.
It’s also about become more efficient with advanced manufacturing of its parts supplied to the aerospace industry. This reduces costs, lead times and takes advantage of Collins’ own engineers and designs for value-added services to its customers.
I spoke with two officials from Collins at the Aviation Week MRO Americas conference in Atlanta April 9-11.
Bjorn’s Corner: MCAS fix on the way
By Bjorn Fehrm
April 19, 2019, ©. Leeham News: Boeing’s CEO Dennis Muilenburg yesterday flew with the final version of the updated MCAS software on a 737 MAX. It will now enter certification flights, having completed 120 Boeing test flights.
Here my perspective on MCAS and the overall Boeing 737 safety record.
Airlines must change tactics to attract maintenance workers

Introduction
April 18, 2019, © Leeham News: Airlines need to create a pleasing work environment even in the industrial atmosphere of “wrench turners” if they are going to attract millennials to become maintenance workers.
Boeing forecasts a need of more than 600,000 mechanics over the next 20 years.
Some airlines, like Delta, faces an aging workforce, which will produce a surge of retirements.
JetBlue, with a young workforce, faces the challenge of attracting young workers who find better paying jobs in other industries.
Even KLM found it has to change the work environment to attract young employees.
Here’s how their stepping up to these challenges.
Union asks Congress to intervene in Boeing inspection issue
Subscription Required
By Bryan Corliss
April 15, 2019, © Leeham News: As Boeing faces federal investigations, shareholder lawsuits, Congressional hearings – and possibly subpoenas – linked to the 737 MAX crashes, another issue flying low on the radar could further complicate the company’s relationship with the Federal Aviation Administration and the elected officials who oversee it.
The issue revolves around the company’s plan to end quality control inspections for several thousand tasks performed by Boeing mechanics in the factory.
That plan – first reported by The Seattle Times in January – involves the use of more “smart tools” to perform work more precisely so that inspections will no longer be required for thousands of tasks. Instead of doing quality checks 100% of the time, as Boeing inspectors have been doing for generations, inspectors will sample 1-in-100 tasks, or maybe less, Boeing executives told the newspaper.
Now, the union for inspectors whose work is going away is asking its influential supporters in Congress to intervene with the FAA. It wants a chance to show the agency data it says proves that the new process will lead to more downstream rework on the assembly line, more injured workers and more production delays.

Training is a factor in the MAX crashes
By Scott Hamilton
April 15, 2019, © Leeham News: This column will no doubt light up the blog-o-sphere.
There’s been a major debate going on since the crash of Lion Air JT610, the Boeing 737-8 MAX that immediately became a huge controversy.
Boeing immediately blamed the pilots. So did some pilots of some US airlines, who said if the Lion Air crew had just flown the airplane, it wouldn’t have crashed. It was a training issue, some said.
Having got tremendous blow back over Lion Air, Boeing publicly held its tongue when Ethiopian Airlines flight ET302 crashed five months later.
Still, Boeing officials quietly still said there was nothing wrong with the airplane.
Some US and Canadian pilots maintained, publicly and privately, that a lack of training and pilot skills in the Third World was responsible.
They’re not entirely wrong.

Bjorn’s Corner: We are getting worldwide flight surveillance

April 12, 2019, ©. Leeham News: In the wake of the 737 MAX accidents an important news event last week went almost unnoticed. After years of preparation, the worldwide coverage of ADS-B via Satellite receivers started with a trial service over the Atlantic.
It’s the Aireon Company which started the trial on April 2nd together with Nav Canada and UK’s NATS (National Air Traffic Control Services).

Ramping the 737 production back up
Boeing already has its plans for ramping production of the 737 back up from the current rate reduction of 42 airplane per month.
According to the information here, this is the schedule for ramping back up:

Introduction
April 11, 2019, © Leeham News: Airlines are showing dramatic reductions in canceled 
flights and aircraft maintenance squawks through its Skywise live diagnostics programs, the most recent of which was rolled out in the US with ultra-low-cost carrier Allegiant Air in January.
Skywise Health Monitoring is the latest program in the Skywise suite of services offered by Airbus to carriers around the world. Skywise Health Monitoring (SHM) joins Skywise Reliability Services (SRS) and Skywise Predictive Maintenance (SPM).
Airbus announced Allegiant’s participation yesterday at the Aviation Week MRO Americas conference in Atlanta (GA).
Summary
- Allegiant cites examples pinpointing one problem misreported, identifying a looming part failure before it happened.
- Delta Air Lines dramatically reduced maintenance cancellations.
- $850,000 in savings in one example.

From the sidelines at the MRO Americas conference
April 10, 2019, © Leeham News: China will be the last country to review and approve fixes to the Boeing 737 MAX, according to the talk here on the sidelines of the Aviation Week MRO Americas conference in Atlanta.
Nobody knows, of course, when regulators will lift the MAX grounding orders. But none is looking for fast action.
And China, the first to ground the airplane, will be the last to lift the grounding, sideline talk here indicates.
