The Boeing Starliner’s first crewed test flight has been officially designated a “Type A mishap” – NASA’s highest level of safety incident – following a comprehensive investigation into the mission’s challenges. The findings, released Thursday, point to a combination of hardware failures, insufficient qualification testing, leadership missteps and broader cultural issues within Boeing that compromised safety standards for human spaceflight. The classification underscores the severity of the anomalies experienced during the flight and signals a renewed focus on accountability and corrective action before Starliner is cleared for future missions.

The Starliner mission, launched on June 5, 2024, aimed to demonstrate Boeing’s capability to safely transport astronauts to the International Space Station (ISS). However, the flight was significantly extended to 93 days after encountering propulsion system anomalies in orbit. Even as astronauts Butch Wilmore and Suni Williams ultimately returned safely to Earth – first via an unscheduled return in the Starliner capsule in September 2024, and then aboard SpaceX’s Crew-9 mission in March 2025 – the incident triggered a detailed investigation into the root causes of the problems. The investigation revealed that a loss of maneuverability as the spacecraft approached the ISS, coupled with associated financial losses, contributed to the “Type A mishap” designation.

Investigation Highlights Systemic Issues

NASA Administrator Jared Isaacman emphasized the seriousness of the situation, stating at a press conference that the technical difficulties encountered during docking with the ISS were “very apparent.” He added, “Today, we are formally declaring a Type A mishap and ensuring leadership accountability so situations like this never reoccur,” signaling a commitment to addressing the underlying issues. An independent Program Investigation Team, chartered in February 2025 and completing its report in November 2025, identified an interplay between hardware failures and programmatic shortcomings as the core of the problem.

The report details how these factors created risk conditions that did not align with NASA’s stringent safety standards. Specifically, investigators found gaps in the qualification of certain systems and a need for improved oversight and decision-making processes. This isn’t the first time Starliner has faced hurdles; the spacecraft has experienced challenges throughout both its uncrewed and crewed missions, highlighting a pattern of issues that prompted the thorough investigation.

Beyond Hardware: A Cultural Assessment

The investigation extends beyond purely technical malfunctions, acknowledging that the problems with Starliner head “beyond hardware,” as noted by the Houston Chronicle. The report points to leadership missteps and cultural breakdowns within Boeing as contributing factors. This suggests a need for organizational changes to foster a stronger safety culture and improve communication between teams.

NASA and Boeing have been collaborating since the Starliner’s return to identify and address the challenges. Technical root cause work is ongoing, and the agency is actively implementing corrective actions based on the investigation’s findings. These actions are intended not only to improve the safety of future Starliner missions but also to enhance the overall safety of other agency programs.

What’s Next for Starliner and Crewed Spaceflight

The “Type A mishap” designation necessitates a rigorous review and approval process before Starliner can be authorized for another crewed flight. NASA will work closely with Boeing to verify the effectiveness of the implemented corrective actions and ensure that all safety concerns have been adequately addressed. The agency is committed to learning from this experience and applying those lessons to future missions, reinforcing its dedication to the safety of astronauts.

The future of commercial crew programs remains a priority for NASA, and the Starliner program is still considered a vital component of that strategy. However, the agency’s focus is now firmly on ensuring that any future flights meet the highest safety standards. The incident serves as a critical reminder of the complexities and challenges inherent in human spaceflight and the importance of continuous improvement, and vigilance.
