Boeing confirmed an unplanned IT outage disrupted commercial and military aircraft production across the United States.

The widespread system failure occurred Monday on the final day of the financial quarter.

Factory operations from Washington to Florida faced disruptions during this critical window for logging aircraft deliveries.

Boeing officials stated the cause is understood and do not believe a cyberattack occurred.

The outage halted final commercial jet inspections and the paperwork required to complete deliveries.

Investors expect the disruption to impact Boeing’s second-quarter delivery figures in the next earnings report.
