Boeing says it has a software application fix all set for its 737 Max aircrafts that will be unveiled to airline authorities, pilots and air travel authorities from around the globe Wednesday, as the airplane manufacturer works to restore trust amongst its customers and the flying public following 2 fatal crashes of the planes in recent months.

On the other hand, those crashes and the relationship between Boeing and the federal agency charged with controling it will be talked about at a U.S. Senate aviation subcommittee hearing on Wednesday. Scheduled to testify are the heads of the Federal Aviation Administration and the National Transport Safety Board, in addition to the Transportation Department’s inspector general, who is examining how the FAA tackled certifying the 737 Max as airworthy, and whether regulators relied too heavily on Boeing’s own safety evaluations in their evaluation.

Those advancements come as transport authorities in Ethiopia prepare to launch initial findings on the cause of the crash of an Ethiopian Airlines Boeing 737 Max 8 aircraft previously this month that eliminated all 157 individuals on board.

A spokesperson for Ethiopia’s transportation ministry informed The Associated Press “a date has actually not been set however (the preliminary report) will be released later on today.” The spokesman states the U.S. National Transportation Security Board, France’s aviation investigative authority BEA and Ethiopia’s Transportation Ministry have actually been conducting the investigation jointly.

After Boeing Crashes, New Attention On The Potential Flaws Of Software

Boeing Brings 100 Years Of History To Its Fight To Restore Its Reputation

The private investigators have actually said there were striking resemblances in between the March 10 crash beyond Ethiopia’s capital city Addis Ababa and the crash of a Lion Air Boeing 737 Max 8 into the Java Sea in Indonesia last October. Both airplanes crashed quickly after departure and both followed similar, irregular flight tracks in the air that suggest the pilots may have been having a hard time to attempt keep the airplanes from going into nosedives.

In the Lion Air jet crash Oct. 29, which killed all 189 people on board, Indonesian private investigators say an automatic flight control system, acting upon erroneous information from a faulty sensor, repeatedly required the nose of the plane down. That system, called MCAS, for Maneuvering Qualities Augmentation System, is developed to prevent the plane from stalling. But the Lion Air pilots apparently did not understand how to counteract the system or disengage it, and were in a futile battle to restore control of the plane.

After the Lion Air crash, numerous pilots grumbled that had not been made conscious of the MCAS system, as it did not exist on previous variations of the 737, nor had they been trained on what to do when the system engages and forces the nose of the aircraft down all of a sudden.

It still is unclear if something comparable occurred on the Ethiopian Airlines jet but the business’s CEO states pilots had been trained on how to manage the brand-new system after the Lion Air crash.

Boeing officials state the company has finished establishing software application upgrades for MCAS intended at avoiding such events in the future. The system will no longer act repeatedly in requiring the nose of the airplane and will act just as soon as if identifying the plane going into an aerodynamic stall. And the MCAS system will depend on information from the two angle of attack sensing units on the aircraft, instead of just one.

In addition, a caution light that alerts the pilot when the angle of attack sensors disagree will end up being basic instead of being a more costly option for airline companies to buy, and it will be contributed to the entire fleet of 737 Max airplane for complimentary.

A Boeing authorities states the software application upgrades have undergone extensive lab and simulator testing, with pilots in a simulator facing a series of mistakes and failures, including sensor errors and other erroneous inputs.

The Boeing authorities states the FAA took part in the evaluation, even demonstrating the software application upgrades throughout a test flight on March 12.

It is not likely that the FAA will act rapidly in certifying the software upgrades and other repairs, especially considering the examination of the accreditation procedure coming from Congress and others. And regulators in Canada, Europe, China and other nations say they will no longer depend on FAA data and will conduct their own tests of the MCAS software application updates prior to allowing Boeing’s 737 Max planes in the air once again. As an outcome, some professionals state it could be months before the airplanes are permitted back into service.
