The US House Committee on Oversight and Government Reform's Subcommittee on Military and Foreign Affairs published a staff report on September 8, 2026, calling for a long-term study of whether repeated aircraft carrier launches, landings and maneuvers that place intense physical forces on the body can damage Navy pilots' brains over the course of their careers.

Republican leaders of the committee, Chairman James Comer of Kentucky and Subcommittee Chairman William Timmons of South Carolina, said the Navy had not adequately investigated possible links between brain injuries and mental health problems and suicides among its aviators. Existing medical procedures focus on identifying specific injuries and may miss damage that develops gradually, and fear of losing flying privileges or harming careers can discourage aviators from seeking treatment.

An April 2026 study of more than 8,500 active-duty aviators found no clear evidence that fighter and attack jet crews were more likely than helicopter, surveillance or transport crews to have diagnosed migraines, mild traumatic brain injuries, or problems with memory or thinking. The researchers acknowledged that aviators who had already left because of health problems preventing them from continuing to fly could be missing from the study, and that they lacked individual pilots' total flying hours and noted reluctance to report symptoms could affect findings.

The 29-page House report cites a Navy proposal for a 12-year health study costing approximately $3.9 million, plus additional funding for longer follow-up. It also describes Project Odin's Eye, a program that checks brain function in special operations personnel and a small number of aviators; the Navy told investigators it was not a formal research program.

Alongside the proposed study, the subcommittee wants Congress to direct the Pentagon to establish a dedicated aviator brain-health program and revise medical policies that discourage treatment. The recommendations call for tracking whether aviators develop health problems related to their flying and making it clearer when they can receive mental healthcare while continuing to serve. The proposals are recommendations to Congress, rather than an announcement that a new study has been funded or begun.
