Overview
- A U.S. Army investigation completed in May and made public on Thursday, Oct. 8, 2026, found that multiple systemic breakdowns combined to cause the Jan. 29, 2025 collision that killed 67 people.
- Investigators identified two failed radio transmissions as the single most salient factor that kept the Black Hawk crew from identifying American Airlines Flight 5342.
- The report says older Black Hawk barometric altimeters can be off by large margins and that the helicopter’s ADS-B Out position broadcast was misconfigured and not transmitting, leaving controllers and other pilots less able to detect the helicopter.
- Army reviewers found that helicopter transit routes and the airliner approach path provided as little as about 75 feet of vertical separation, a margin too small to absorb known instrument errors, and the service has since inspected and reconfigured 3,585 helicopters for ADS-B issues and tightened training and monitoring.
- Families of the victims say the report lacks individual accountability and are pressing Congress to force wider collision-avoidance technology rules while lawmakers work to reconcile competing House and Senate aviation-safety bills.
