## Abstract

The FAA is removing the provision describing an abbreviated taxi clearance. Previously, air traffic controllers issued abbreviated taxi instructions to aircraft en route to their assigned departure runway, which allowed pilots to cross all runways that intersected the taxi route to their departure runway. The FAA no longer uses these abbreviated taxi clearances and is removing the provision of the regulation that describes this clearance. This action aligns the regulation with current air traffic control practice and responds to the National Transportation Safety Board (NTSB) Safety Recommendation Numbers A-00- 67 and -68.
