Customs is available 24 hours a day, Monday through Friday, with on-call coverage from Detroit Metro on weekends. The field is designated an LRA airport requiring ADCUS notification ahead of arrival. Dispatchers planning international legs into KYIP should confirm ADCUS timing directly with airport operations given the weekend on-call structure.
Are there restrictions on scheduled or charter operations at Willow Run Airport?
Willow Run Airport (KYIP) is closed to scheduled air carrier operations using aircraft with more than 9 passenger seats. Unscheduled air carrier operations with more than 30 passenger seats require prior permission, with 72 hours advance notice through the airport operations manager.

Operators should coordinate directly with airport operations before filing such flights.
Is there a known runway confusion risk at KYIP?
Yes, Willow Run Airport (KYIP) is flagged as a wrong-surface arrival risk airport. The concern involves closely aligned pavement between Taxiway G and Runway 09/27. Crews should brief this hazard during approach planning, particularly at night or in reduced visibility, to avoid mistaking the taxiway for the runway. This is a documented airport remark rather than a general caution, so flight crews operating into KYIP should treat it as a specific local risk factor.

Business aviation traffic at Willow Run Airport (KYIP) peaks in the fall months, with October recording 1,331 operations and November recording 1,231 operations, according to FAA TFMSC data. This compares to lower winter counts, such as 807 operations in January and 808 in February. September also shows elevated activity at 1,174 operations. Dispatchers scheduling flights into KYIP during the fourth quarter should anticipate the busiest period of the year at this field.
