300 US Passenger Jets Have Deadly Flaw

(5MinNewsBreak.com) – Adding a new entry to a pile of bad news, Boeing recently discovered a significant electrical flaw in its 777 airliners that could potentially cause a fire or an explosion.

This issue is linked to inadequate electrical insulation near the fuel tank and was highlighted in a Federal Aviation Administration (FAA) proposal in March.

The FAA’s Airworthiness Directives note warns, “This condition, if not addressed, could result in an ignition source inside the fuel tank and subsequent fire or explosion.”

This flaw is relevant to nearly 300 Boeing aircraft in the U.S., spanning the 777-200, –200LR, –300, –300ER and 777F series.

Despite being an older model, the Boeing 777 is widely used internationally by major U.S. carriers such as American and United Airlines.

This model was the same type involved in a recent incident where a Singapore Airlines flight unexpectedly dropped 6,000 feet, killing a 73-year-old man and injuring others.

The FAA has proposed corrective actions that would involve electrical bonding and grounding improvements in the center fuel tank. These actions reference service actions that Boeing had already suggested in a November 2023 alert.

If implemented across all affected planes, these fixes are estimated to cost around $14 million.

“The proposed AD, which the FAA issued in March 2024, would require installing electrical bonding and grounding to a component in the center fuel tank. It would make mandatory service actions that Boeing described in a November 2023 alert bulletin,” stated an FAA spokesperson.

Responsibility for these repairs would fall not on Boeing but on the operators and airlines that own these aircraft.

The plan includes inspecting each plane for approximately 90 hours and adding protective Teflon sleeves and cap fasteners to parts of the center, left and right main fuel tanks.

This initiative follows a 2017 FAA directive to lessen similar risks across a broader range of 777 models and prevent potential arcing from fault currents or lightning strikes, which could ignite fuel vapors and lead to an explosion.

The FAA highlighted this issue in March and gave Boeing a May 9 deadline to respond. If the proposals are enacted, Boeing would have up to 60 months to complete the necessary modifications, which suggests the issue is not deemed an immediate threat.
