Electrical Issues Affecting More Boeing 737 MAX | Jetline Marvel

Boeing will 'very shortly' increase 737 MAX manufacturing to 38 per month.

On most of Boeing’s next-generation narrowbody aircraft, a new problem has arisen. Boeing recommended that 16 customers temporarily park some Boeing 737 MAX aircraft earlier this month pending inspections and rectifications involving an electrical power system part. Although the problem was unexpected, it only affected a small number of MAX jets. However, according to some industry reports, it can affect more jets than previously thought and may spread to other parts of the plane.

According to industry sources, more Boeing 737 MAX aircraft would need to undergo checks than originally expected in order to look for any deficient products that need to be fixed. According to the most recent update, other areas of the 737 MAX aircraft are experiencing electrical system grounding problems. The issue, while not complicated and certainly not to the extent that caused the plane to be grounded for so long, would necessitate some time on the ground. The biggest concern is ensuring that segments of the electrical power grid have ground paths.

Boeing suggested to 16 customers last week that they ground those Boeing 737 MAX aircraft from operations. Customers were instructed to inspect and make any required adjustments to ensure that a part of the electrical power system had a proper ground path. Following Boeing’s announcement, many airlines grounded MAX aircraft from their fleets while waiting for more details. Boeing is working with the Federal Aviation Administration (FAA) in the United States to resolve the issue, which Boeing described as a production issue.

According to Boeing’s phrasing, it’s not a given that the aircraft listed aren’t properly grounded where they should be. As a result, some aircraft would just need to spend some time on the ground for inspection before returning to service. The risk of an electrical failure is not insignificant. This is why Boeing has issued an alert to MAX customers who might be affected. As Boeing and the FAA assess the situation, more information will become available. At this time, the exact number of planes affected by the problems is unclear.


FAA proposes requiring four key Boeing 737 MAX design changes



Boeing 777-9 Begins Certification Flight Testing with FAA Onboard

Boeing 777-9 Begins Certification Flight Testing with FAA Onboard

The 777-9 has commenced certification flight testing at Boeing Field in Seattle. This is a crucial step under the supervision of our regulator to certify the airplane and deliver it to customers worldwide.

Amidst Boeing’s current challenges, the B777X stands out as a project that could revitalize the brand. It is highly anticipated, and Boeing is keen to clear FAA certifications to release it as soon as possible.

The aircraft is two years behind its initial commitment date. During this time, the company has rigorously tested it under various conditions to ensure its readiness for commercial service.


Boeing has announced that the 777X will be used for both passenger and freighter services, depending on customer requirements.

Boeing’s 777X program has achieved a major milestone with the Federal Aviation Administration (FAA) granting approval to begin certification flight tests, marking a significant step towards the aircraft’s entry into commercial service.

The European Union granted approval for this merger in February, and Korean Air anticipates U.S. regulatory approval by the end of October.


Following Airbus’ breakthrough with Korean Air, Reuters reported in April that Korean Air was considering a new Boeing order focused on the 777X, an advanced version of the 777 mini-jumbo.

Boeing 777-9 First certification

The first certification flight test of the 777-9 took place on Friday evening, with FAA personnel onboard alongside Boeing’s pilots and flight test team.

According to The Seattle Times, the aircraft departed from Boeing Field shortly after 6 p.m. and landed nearly two hours later after flying along the Washington and Oregon coast.

The 777X, an upgraded version of the successful 777 twinjet, features new engines and carbon composite wings with folding wingtips to accommodate standard airport gates.


The first variant, the 777-9X, is designed to carry 426 passengers in a two-class configuration for long-haul international flights.

Boeing B777x total orders

Boeing has secured 481 orders for the aircraft, with Emirates being the largest customer, having ordered over 200 units. The planemaker has already built and stored 22 777X jets, with an additional six in various stages of assembly in Everett, Washington.

Boeing is close to finalizing a significant deal to sell approximately two dozen 777X jets to Korean Air, with an estimated value ranging from $4 billion to $6 billion, as reported by Reuters.


Industry sources suggest that the agreement could be concluded as early as the Farnborough Airshow in July. Korean Air, South Korea’s largest airline, has been in discussions about returning to Boeing for its long-haul aircraft needs.

The Boeing 777X vs A350 is one of the most popular comparisons among aircraft as of now. The Airbus A350 has been operating for more than eight years, and its promising performance helps airlines in terms of efficiency and customer satisfaction, particularly in noise and vibrations.

The next generation Boeing 777X can fulfill the same requirements, with 777x first delivery given to Emirates Airlines, the launch customer for this aircraft. It remains to be seen how the Boeing 777X vs Airbus A350 will compete against each other in the future.
