Boeing Uncovers Another Potential Design Flaw With 737 Max

As hundreds of Boeing 737 Max jets remain grounded awaiting approval from aviation regulators, the troubled planemaker has discovered yet another potential hurdle.
The plane was grounded worldwide in March last year after two crashes that killed 346 people. The company determined a software fix was likely to correct the issue with the automatic safety feature that caused the crashes. However, as part of a December audit of the plane's safety ordered by the US Federal Aviation Administration (FAA), Boeing found 'previously unreported concerns' with wiring in the 737 Max.
The company informed the FAA last month that it is looking into whether two sections of wiring that control the tail of the plane are too close together and could cause a short circuit -- and potentially a crash if pilots did not react appropriately.
A Boeing spokesperson confirmed the report to CNN, saying the issue was identified as part of a rigorous process to ensure the plane's safety.
"Our highest priority is ensuring the 737 Max meets all safety and regulatory requirements before it returns to service," the spokesperson said.
"We are working closely with the FAA and other regulators on a robust and thorough certification process to ensure a safe and compliant design."
The spokesperson said it will be premature to speculate whether the discovery will lead to new design changes for the plane, or further extend the timeline for its recertification.
CNN said it will be a challenge for Boeing's new chief executive David Calhoun who officially takes over the job on January 13 after former CEO Dennis Muilenburg was ousted on December 23.
"A change in leadership was necessary to restore confidence in the company moving forward as it works to repair relationships with regulators, customers, and all other stakeholders," the company said in December.
Earlier in December, the company announced it will take the dramatic step of suspending production of the 737 Max in light of the continued setbacks to recertification.
Orders for the 737 Max dried up following the grounding, and it was not until November that Boeing recorded its first new orders since the grounding.
In the meantime, the company continued to produce the planes at a rate of 42 jets a month in hopes of quick recertification by airline regulators around the globe.
But as the process was pushed into 2020, Boeing said the plane's uncertain future had forced it to pause production and prioritise the delivery of about 400 airplanes it has in storage.
