Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
IFR Altitudes and Changeover Updates
The FAA amends, suspends, or revokes required IFR (instrument flight rules) en-route altitudes and changeover points for specified Federal airways, jet routes, and direct routes to ensure safe and efficient instrument flight operations. These regulatory amendments apply to all aircraft operating in flight over the specified routes and become effective at 0901 UTC on July 9, 2026.
Specific Airway Segments Deleted or Unusable
The rule deletes or lists certain airway segments and jet-route segments as "UNUSABLE" or removes them from the route structure (examples in the text include PULLMAN, MI VOR/DME segments shown as UNUSABLE; Jet Route J94 and Jet Route J548 deletions; various VOR Federal Airway deletions). These deletions and 'UNUSABLE' designations take effect at 0901 UTC on July 9, 2026.
FAA Certifies Minimal Economic Impact
The FAA states that the amendment involves routine technical regulations and "does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal." The FAA also certifies the amendment "will not have a significant economic impact on a substantial number of small entities" under the Regulatory Flexibility Act.
