NASA Declares Starliner Crewed Flight Test a Type A Mishap, Cites Leadership and Engineering Failures

NASA has officially classified the first crewed flight test of Boeing’s CST-100 Starliner spacecraft as a Type A mishap, the agency’s highest level of mission failure. The decision follows the release of a report from an independent Program Investigation Team examining issues stemming from the Commercial Crew Program mission, announced on February 19, 2026.

Starliner’s Troubled Journey

NASA Administrator Jared Isaacman revealed that the Starliner spacecraft has experienced challenges throughout its development, from uncrewed missions to its recent crewed flight. “Technical difficulties encountered during docking with the International Space Station were incredibly apparent,” Isaacman stated. The initial crewed mission, launched on June 5, 2024, with astronauts Butch Wilmore and Suni Williams aboard, was originally planned for eight to fourteen days but was extended to 93 days due to anomalies detected in the propulsion system while in orbit. The astronauts returned to Earth aboard a SpaceX Crew Dragon capsule.

Root Causes of the Failure

The investigation, completed in November 2025, identified a combination of factors contributing to the problems encountered during the Starliner test flight. These included hardware failures, qualification gaps, leadership errors and organizational culture issues that did not align with NASA’s human spaceflight safety standards. Isaacman emphasized that while Boeing built the Starliner, NASA accepted the spacecraft and launched the astronauts, taking responsibility for the situation.

Accountability and Corrective Actions

Isaacman stressed the importance of transparency and accountability, stating that NASA permitted overarching programmatic objectives – specifically, the goal of having two providers for astronaut transport – to influence engineering and operational decisions. “We are correcting those mistakes,” he said, adding that NASA is ensuring leadership accountability to prevent similar situations from occurring in the future. NASA will implement corrective steps and collaborate with Boeing to address all recommendations from the investigation before authorizing Starliner’s next mission.

Looking Ahead

NASA expressed its commitment to working with Boeing to implement the necessary remedial measures and return Starliner to flight readiness. The agency anticipates a future where Starliner can reliably contribute to crew transportation to and from orbit, but only “when it is truly ready,” according to Isaacman. Further details on the investigation and NASA’s response were outlined in a message from Administrator Isaacman on February 19, 2026.
