Boeing to change 737 MAX flight-control software to address flaw
WASHINGTON/SEATTLE (Reuters) - Boeing Co plans further changes to the software architecture of the 737 MAX flight-control system to address a flaw discovered after a test in June, two people briefed on the matter said late on Thursday.
he redesign, first reported by the Seattle Times, involves using and receiving input from both flight control computers rather than one.
The move comes in response to an effort to address a problem discovered in June during a Federal Aviation Administration(FAA) simulator test.
This is on top of earlier announced changes to take input from both angle-of-attack sensors in the MCAS anti-stall system linked to two deadly crashes that led to a global grounding of the plane.
Boeing still hopes to complete the software redesign by the end of September to submit to the FAA for approval, the sources said.
For decades, 737 models have used only one of the flight control computers for each flight, with the system switching to the other computer on the following flight, according to people familiar with the plane’s design.
The FAA said in June that it had identified a new risk that would need to be addressed before the plane could be ungrounded.
Under a scenario where a specific fault in a microprocessor caused an uncommanded movement of the plane’s horizontal tail, it took pilots too long to recognize a loss of control known as runaway stabilizer, a Boeing official said at the time.
Boeing Chief Executive Dennis Muilenburg told analysts last month that he was confident the 737 MAX would be back in service as early as October after a certification flight in “the September time frame”
Southwest Airlines and Air Canada, however, have taken the 737 MAX off their schedules until January.
The FAA declined to comment on the Seattle Times report. Boeing did not respond immediately to a request for comment.

probably wouldn't need an ipad to fly it either.
just a suggestion…getting wrapped up in timing will drive you mad-it habbens when it habbens. Witness last night and the copious amounts of cheese that could have been dispensed with all that wine.

July Payrolls Preview: Beware The Census Hiring Surge
Now that the Fed is once again extremely sensitive to incoming data - or at least that's what the market thinks - and especially bad incoming data as today's disappointing ISM demonstrated, which sent stocks surging on hopes of more rate cuts (at least until Trump's subsequent tariff shocker), tomorrow's payrolls report is suddenly extremely important for the Fed's reaction function: a strong beat has the potential to crush stocks and send yields sharply higher, and of course, vice versa. That said, a beat to the relatively modest consensus expectation of 165K is virtually assured due to the wildcard that is census hiring which will be between 10K and 50K, and which the BLS will surely fully milk following political instructions from "above."
US nonfarm payrolls are seen coming in at 165k in July, a reading which would push the three-month average down to 153k from 171k in June. The jobless rate is seen unchanged at 3.7%, though the Conference Board’s consumer confidence data does signal some potential downside. We have seen only a partial slate of business surveys ahead of the NFP report, and they seem to signal some cooling in labour market momentum.
The Street expects 164k nonfarm payrolls will be added to the US economy in July, following 224k in June (12-month trend rate is 192k). Fed Chair Powell looks at a three-month rolling average of headline payrolls, which after the upside in June, is running at a clip of 171k, and has been ticking higher for three straight months – a consensus 164k in July would knock the three-month average back to 153k.
Looking at just one bank's forecasts, Goldman estimates nonfarm payrolls increased 190k in July, 25k above consensus of +165k. While July employer surveys declined on net, jobless claims and job availability measures remain at very strong levels, and we also expect a boost from Census hiring worth 10-20k. Additionally, Hurricane Barry struck the Gulf Coast too late in the survey week to have a significant impact on the report.
JOBLESS CLAIMS:
Weekly claims data within the survey periods is unchanged on June, suggesting some stability; initial jobless claims were 216k in the 13th July week vs 217k in the 15th June week; for reference the four-week moving average was also stable, falling slightly from 219k to 218.75k.
Job availability. The Conference Board labor market differential—the difference between the percent of respondents saying jobs are plentiful and those saying jobs are hard to get—rebounded by 5.2pt to +33.4 in July, just below the cycle-high. Other job availability readings are somewhat backward-looking at this point, but were somewhat softer on a sequential basis: JOLTS job openings declined but remained high (-49k to 7,323k in May) and the Conference Board’s Help Wanted Online index edged lower (-0.2pt to 102.4 in June).
Census hiring. Temporary employment related to the 2020 Census has significantly lagged that of 1999 and 2009. However, address canvassing scheduled for August will require tens of thousands of temporary workers to be hired and trained. Given this and given that the 200+ regional Census offices were opened in late June, expect a visible boost from Census hiring in tomorrow’s report.
Employer surveys. Business activity business surveys were sequentially firmer in July (with small net gains in the manufacturing sector and a moderate increase in the services sector), but the employment components of those surveys underperformed (-1.2pt to 52.3 for manufacturing, -0.9pt to 53.5 for services). As shown in Exhibit 2, however, the level of the labor-market components still suggests job growth running at a healthy pace (of around 175k per month). Service-sector job growth rose 154k in June and averaged 134k over the last six months, while manufacturing payroll employment rose 17k in June and has increased by 8k on average over the last six months.
NEUTRAL FACTORS:
ADP. The payroll-processing firm ADP reported a 156k increase in July private employment, slightly above consensus and a sizeable pickup from the 112k pace it reported in June. The ADP report was slightly firmer than our previous assumptions—and in our view suggests that the underlying pace of job growth remains solid.
Job cuts. Announced layoffs reported by Challenger, Gray & Christmas remained unchanged in July at 47k (SA by GS), but are still somewhat above their July 2018 level (+15k yoy). A retracing of announced layoffs in the automotive industry (-6k mom sa) roughly offset a rise in the transportation industry (+4k) and smaller increases in other industries.
