Announce NTSB Chairman Jennifer Homendy on Wednesday. (Door plugs replace unnecessary emergency exit doors.) That means the failure could happen anywhere between Malaysia, Spirit's facility in Wichita, or a Boeing plant near Seattle.

“We have no indication right now as to where this will happen in this process,” Homendy told reporters after a Senate hearing. Wall Street Journal. “This could be anywhere along the line,” she said, adding that the NTSB was not focused solely on manufacturing.

Boeing has getting help from external sources Much of its manufacturing goes to outside suppliers like Spirit, which has built sprawling global supply chains, including countries like Malaysia.

The Southeast Asian country is the region's second-largest aviation hub, and the industry there generated $3.4 billion in revenue in 2019, according to documents From the Malaysian Investment Development Authority. Suppliers based in Malaysia work with both major aircraft manufacturers, Boeing and Airbus.

Spirit has a factory in Subang, near Kuala Lumpur, the country's capital. The Boeing supplier opened the 242,000-square-foot facility in 2009.

“Although Spirit is an airline, it is also a people company, and it was the people in Malaysia that convinced me that this was a great place for Spirit to grow globally,” said Jeff Turner, then CEO of Spirit. He said at the time.

Boeing's return to Asia

This incident complicates Boeing's return to Asia, specifically to China. At one time, China was one of Boeing's most promising markets, thanks to the country's booming aviation sector. But Chinese officials froze Boeing aircraft orders in 2019, following two fatal crashes of the 737 MAX 8.

Boeing is tiptoeing back into the market, with the manufacturer delivering its first plane in more than four years to a Chinese airline. Last December.

But now, Chinese regulators and airlines are conducting additional checks on Boeing planes in the wake of the Alaska Airlines incident Wall Street Journal I reported earlier this week. (The aircraft being examined are not 737 MAX 9)

Other airlines are working to fill the gap left by Boeing's absence. Chinese airlines switch to Airbus A320 series during Boeing grounding: There were more than a thousand A320s operating in China by the end of 2022, compared with just over 940 Boeing 737s, according to Bloomberg. China also has a domestic competitor to the 737: the C919, made by state-owned COMAC.
