FAA Flags Colorado’s RMMA for Most Safety Incidents, Implements New Traffic Flows

The FAA is revising RMMA procedures following a FOIA-released memo that identified unusually high safety events.

Overview

  • An FAA memo says Rocky Mountain Metropolitan Airport leads the nation in “Potentially Significant Events,” a broad category that includes runway incursions and airborne safety issues.
  • Effective June 16, 2025, the FAA adjusted operating procedures at RMMA by instituting structured traffic flows to and from the runways, while leaving published instrument procedures unchanged.
  • The FAA memo called for a safety working group to begin meeting at the end of June, and the agency is urging local flight schools to coordinate on traffic patterns.
  • Neither the FAA nor the airport has released exact PSE counts, and RMMA and Jefferson County emphasize that routing and air traffic procedures are set by the FAA.
  • Airport use has grown and a fatal May crash has heightened scrutiny, as Superior’s mayor presses safety concerns and the airport says the FAA reports improved safety since the changes.
