Boeing’s 777 Freighter Production Stalled for Two Months Over Supplier Dispute

Boeing has experienced a significant disruption in its production lines due to a dispute with Vaero, a small supplier based in Florida. This disagreement has halted the manufacturing of the 777 freighter for close to two months and has also impacted the output of the 767 model, including variants such as freighters and the KC-46 aerial refueling tankers. Workers involved with Boeing and related court documents have confirmed these delays.

The issue began when Boeing filed a legal complaint in August, accusing Vaero of ceasing deliveries of a crucial wing part called the trailing-edge rib kit. This component is manufactured at Boeing's Everett, Washington facility, which supports wing assembly for both the 777 freighter and 767 programs. The complaint revealed that the halt in deliveries was resulting in losses estimated at $6.5 million daily for Boeing. The company described the trailing-edge rib kit as an "indispensable" part for these aircraft, emphasizing that Vaero was the sole supplier.

Although Boeing and Vaero reached a settlement in late September, production of the 777 freighter has not resumed, according to three Boeing employees familiar with the matter who requested anonymity due to restrictions on speaking publicly. The disruption also affected 767 production lines, but since the settlement, Boeing has received some parts necessary to continue work on that model, according to one worker.

This incident highlights the vulnerability of aerospace supply chains, where a dispute involving a single supplier can bring production of in-demand aircraft to a standstill. The lawsuit was initially reported by Law.com in August, but the nearly two-month suspension of production was not widely known until now. Boeing declined to comment on the situation, and Vaero did not respond to inquiries.

In response to the supply chain disruption, Boeing is attempting to transfer production of the trailing-edge rib kit in-house, according to two sources close to the matter. This part is used in wing assembly for both the 767 and the current-generation 777 freighter. However, Boeing's 777X aircraft, which features composite wings, remains unaffected by the dispute.

Without the necessary parts from Vaero, Boeing had to remove two partially assembled 777 freighters from its final assembly line. Aviation consultancy IBA data reviewed by Reuters identified one of these aircraft as intended for FedEx. FedEx has not commented on the delay.

So far this year, Boeing has delivered 21 777 freighters, according to company data. There are also a few freighters with wings already assembled before the dispute began that may still be delivered by the end of the year, according to two Boeing employees. This situation underscores the delicate balance in aerospace manufacturing, where the reliance on specialized suppliers can create significant bottlenecks when conflicts arise.

The aerospace industry continues to face challenges in stabilizing supply chains amidst rising demand for cargo and military aircraft. Boeing’s efforts to internalize the production of critical components could represent a strategic move to reduce future risks and improve control over manufacturing timelines. However, the recent disruption serves as a reminder of how quickly production schedules can be affected by issues beyond a manufacturer’s immediate control.
