After the discovery of a new flaw in Boeing’s most sold and currently globally grounded 737 Max jets by the United State airline regulators last week, analysts say that it would not be until late this year that the jest would be allowed to fly once again in the air, claimed reports published din the American media.
The latest flaw was found in the in-flight control chip of the planes.
According to a Boeing official quoted in the media, the flaw that had been discovered relates to the troubled recertification process in the planes which has been linked to a chip failure which could resulted in an uncommanded movement of a panel on the aircraft’s tail which eff3ectively automatically points the nose of the downward. According to a report published in The Wall Street Journal, in the ensuing emergency tests done to find a solution to resolve the issue also revealed that more than expected time was taken by pilots to resolve the issue.
This new revelation is a new issue for Boeing and the 737 Max planes which is different and in addition to the issues that Boeing is already facing in relation to the MCAS automated flight control system of the jets. Boeing still claims that it already has a ‘software’ fix to the MCAS automated flight control system issue which can be applied to make the planes safe and flight worthy. The Boeing official reportedly told The Wall Street Journal that the US regulators – the Federal Aviation Administration, would be presented with the solution and the fixes by Boeing by this fall.
“We’re expecting a September time frame for a full software package to fix both MCAS and this new issue,” the official said. “We believe additional items will be remedied by a software fix.”
It would take at least two months for the Boeing 737 Max planes to fly again after Boeing submits that software package solution with the FAA. Time would also be needed by the FAA to recertify the planes. Further, agreements also have to be made by Boeing with airlines and pilot unions about the time that pilots would require to train and adapt to the changes. Additionally, more time would be needed by the airlines to further undertake complete necessary maintenance checks of their own.
There were no comments on a specific timeline for the plane’s recertification by FAA spokesman Lynn Lunsford. “We have steadfastly stayed away from offering any timelines,” he told the media.
Two fatal accidents, one in March this year and another just five months before that, forced he grounding of all 737 Max jets of the company all across the world a few months ago. That incident also sent shockwaves through the global aviation industry. The single-aisle 737 plane is the most widely sold commercial aircraft of the world.
