Booking a Learjet slot
The hangar works Monday to Sunday, 5:30 AM to 4:00 PM CT, and weekends are normal operating days at the normal rate. A 50% deposit locks the slot and counts toward the invoice. Parts we supply carry a 17% markup, capped at $10,000 per project.
You can bring the aircraft to KRBD 24/7, with FBO support from Jet Access. While it’s here, you get maintenance updates. Before it leaves, our cleaning partner cleans the cabin and exterior at no charge.
