Pilots flying into Aspen’s Pitkin County Airport (ASE) should be aware of FAA Notice NOTC4835, which addresses two safety issues at the field. The notice attempts to mitigate ongoing safety incidents at the Colorado airport involving aircraft, vehicles and pedestrians on runways and non-movement area. Outside the skiing season, the movement/non-movement area boundary line was repositioned closer to Taxiway A4.
In other action, the airport will reduce the tower’s times of operation by two hours in the evening, effective July 11. Currently the tower is open from 7 a.m. to 10 p.m. Beginning this Thursday, the tower will continue to open at 7 a.m. but close at 8 p.m.
When the tower is closed, aircraft should use the common traffic advisory frequency (CTAF) 118.85 and be aware that no Class D ATC services will be available. Some airport lighting will be controllable through the CTAF, while IFR clearance can be obtained through Denver Center on 125.35.
