The 737 MAX is back in spotlight with a new problem regarding design flaws that is relatively concerning. It has created more doubt around the aircraft's return into service.

This new issue surrounds a potential short circuit. This new wiring issue has now been confirmed by Boeing and the Federal Aviation Administration. 

Wiring issue was found by relevant parties during Boeing's extensive testing phase for their 737 MAX which as we know is still grounded after two deadly crashes killing a total of 346 people last year.


What Boeing has to say

Boeing's spokesman said the U.S. planemaker "identified this issue as a part of the rigorous process, and we are working with the FAA to perform the appropriate analysis. It would be premature to speculate as to whether this analysis will lead to any design changes."

However, it is unclear whether this issue may eventually result in a design change which would eventually push away its safely return in service.

Boeing along with the regulators are looking into everything from the wiring to the engines. As per reports, the company is looking at whether two bundles of critical wiring are too close together and could cause a short circuit which may lead to an eventual haul loss.

How often are simulator tests being carried out

Boeing is now expected to replicate lively scenarios in flight simulators. Constant flight simulator tests are being conducted since the grounding so as to get its 737 MAX recertified and back in service safely.

The MAXs return into service would be delayed if the all delivered and already built aircraft need the wiring bundles to be organized or changed. More that 800 aircraft will need the fixing. 


How may airlines respond

Eventually, this delay may see more and more airlines lose faith and patience with the aircraft resulting a huge burning issue to the manufacturer. Cancellations may also increase for the type.

New York time reported that as per Boeing's senior engineer fixing such wiring issue was not unusual to Boeing.

The FAA has explained the wiring issue as catastrophic eventually pushing back the return of the 737 MAX.

However, Boeing has already completed the revision of Manoeuvring Characteristics Augmentation System (MCAS) and still awaiting the approval from the regulators and FAA.Other testings and reviews are still going on.

Boeing's CEO Dennis Muilenburg was fired due to his incapability to fix these issue. David L. Culhoun, who has been appointed as the new CEO will officially take his role on 13th January, 2020.
