On Wednesday, 28th April, Boeing announced that it had delayed the deliveries of its Boeing 737 Max Jets. The decision to delay the deliveries came after the electrical issue in B737 Max. This electrical fault forced the airlines to ground their 737 Max Jets once again.
A total of 106 B737 Max Jets are grounded across the world due to electrical faults. Out of these, 71 are registered in the United States. The aircraft has a very unpleasant timeline since its launch. It was grounded in March 2019, after the Lionair and Ethiopian Airlines crash. B737 Max was grounded for 2 years after these two deadly crashes. The aircraft struggled to gain approval from the regulators after plenty of safety checks. Moreover, when the aircraft was making its revival and started making a good return a new fault emerged that forced several airlines to ground the aircraft.
Boeing 737 Max – Previous MCAS Software Issue
Previously the aircraft faulted with its software, The Maneuvering Characteristics Augmentation System (MCAS), introduced with B737 Max. The Boeing Company spent thousands of person-hours to fix the problem, which presents a very turbulent ride for the aircraft type.
While airlines thought it’s the best time to bring the jets back into action, it turned back to the hangars, which indicate bad luck for the B737 Max. The aircraft returned to the skies after receiving approvals from EASA and FAA. However, yet another issue was reported by Boeing.
Aircraft Backlog due to Grounding
The American Manufacturing giant, “Boeing” was aiming to restore its 737 Max production to 31 aircraft per month by early 2022. However, it can produce even more than that but due to the groundings, it created a huge backlog which prevented Boeing from producing extra 737 Max. Moreover, the current focus for the company is to deliver its current backlog of already built jets.

Electric Fault Recovery
Boeing believes that it would take a few days per aircraft to resolve the electrical issue. However, it is known that the electric system’s fault involves several other systems, which include the Standby Power Control Unit, Main Instrument Panel, and Circuit Breaker. Although, Boeing has already started working to find a solution to the problem.
The current electrical issue is not linked to its previous software issue that forced the aircraft to be grounded worldwide.
The FAA mentioned that the current grounding “isn’t related to the recertification of the flight control system on the 737 MAX, ungrounding of the aircraft, or its return to service.”
CEO Dave Calhoun told CNBC earlier Wednesday that he expected to finalize the repair instructions “in relatively short order” but did not provide an exact date. The Federal Aviation Administration, which would approve the fixes, said it is “continuing to work closely with Boeing on this issue.”
