U.S. Federal Aviation Administration (FAA) has reportedly given the green light to Boeing Co (NYSE:BA) to initiate crucial flight tests on its 737 MAX 10 aircraft, marking a significant step toward readying the jet for commercial operations. 

Citing the communication addressed to employees, the Wall Street Journal notes that the 737-10 is the largest offering within Boeing's MAX family of single-aisle planes. 

Notable carriers such as United Airlines Holdings Inc (NASDAQ:UAL), Ryanair Holdings AG (OTC:RYAAY) (OTC:RYAOF), Air India, and SunExpress have already placed orders for these jets, signifying considerable market interest.

Boeing's journey in recent years has been fraught with challenges, including delays and obstacles in getting new aircraft into service, particularly concerning the restart of deliveries for its 737 MAX planes following two tragic crashes that led to their grounding in 2019.

Although Boeing had anticipated FAA certification for the MAX 10 by the previous year, subsequent delays pushed the timeline further. Earlier projections from Boeing executives hinted at an approval expected late this year or early 2024.
