Boeing, already grappling with a series of challenges, faced yet another setback as one of its planes was compelled to make an emergency landing due to fuel leakage from its landing gear.

This incident, the latest in a string of troubles for the beleaguered manufacturer, marks the fifth involving a Boeing aircraft within a week.

The forced landing, currently under investigation, occurred on Monday when a San Francisco-bound 777-300 departing from Sydney was observed with fluid leaking from its undercarriage.

The preceding incidents include one that transpired just hours earlier, resulting in 50 passengers being injured on Boeing’s flagship 787-Dreamliner.

The cumulative impact of these events led to Boeing losing over $4 billion overnight, with shares plummeting more than 4 percent on Tuesday morning, the Daily Mail reported.

Compounding Boeing’s challenges, a former Boeing employee turned whistleblower was found dead by an apparent suicide on Saturday.

The whistleblower had previously revealed concerns about the use of substandard parts in Boeing planes.

Additionally, the Federal Aviation Administration (FAA) disclosed that Boeing failed 33 out of 89 audits during an examination of the Boeing 737 Max, a model the company had planned to upgrade with the long-delayed Max 10.

In response to the latest incident on Monday and the preceding ones, United Airlines has reportedly requested Boeing to halt work on unreleased jets, signaling a decline in carriers’ confidence in the manufacturer.
