Potential electrical failures in Boeing 737 MAX aircraft could affect more components than previously anticipated. This was reported on April 16 by The Wall Street Journal.
Last week, aircraft manufacturer Boeing recommended its 16 customers eliminate a potential electrical issue on its 737 MAX aircraft.
According to The Wall Street Journal, the problem is related to the paint application in early 2019. The technology then applied could affect the grounding of the airliner systems and affect the cockpit instrument panel and emergency power system. Potential problems can be present in 90 aircraft transferred to airlines and in many airliners that have not yet been transferred to customers.
The publication notes that air carriers are counting on the Boeing 737 MAX in light of the increase in passenger traffic. At the same time, trucking companies did not experience problems due to the suspension of the use of these aircraft and redistributed the load to other vehicles.
Operation of the Boeing 737 MAX was suspended in March 2019 after two plane crashes that killed 346 people.
In October 2018, a liner of this model of the Indonesian company Lion Air crashed, killing all 189 people on board. The plane crashed in Indonesia 13 minutes after taking off from the airport.
On March 10, 2019, the same aircraft of Ethiopian Airlines crashed in Ethiopia a few minutes after takeoff. The disaster killed 157 people, including three Russians.
Boeing management acknowledged that in both cases there was a malfunction in the maneuverability improvement system. After that, several countries suspended the operation of this series of liners for safety reasons.
In November last year, the US Federal Aviation Administration (FAA) gave permission to reopen these aircraft.
In January 2021, the European Union Aviation Safety Agency (EASA) announced that the modified Boeing 737 MAX was approved for operation in Europe. The liner was updated with software, electrical wiring was repaired, it underwent maintenance and crew retraining.
