Welcome to Monument Aircraft Services, LLC ![]() Based at Walker Field Airport in Grand Junction, Colorado (GJT), Monument Aircraft Services has provided aircraft maintenance, troubleshooting and repair since 1995. With over 30 years of experience with every aircraft type, from J-3 Cubs to big Boeings, we deliver comprehensive services and capabilities to meet any maintenance need. While most of our customers operate piston singles, we are experienced with most light and cabin-class twins, helicopters and turbines. If it burns av-gas or kerosene, we can help. Our 110,000 square foot shop is modern, clean and well equipped. We have the capabilities to perform unusual repairs or modifications and have FAA Inspector Authorization for many field approvals. Our staff includes a licensed IA, experienced A&Ps, and support personnel who are aggressive in solving problems with the care and attention to detail that many shops lack. Our focus is on fast turnaround, exemplary customer service and complete satisfaction. Aircraft On Ground (AOG) cases within 200 miles are cheerfully serviced. We can fly parts and technicians to your location and get you in the air as fast as possible. And, if you need ferry service to our facility, we will fly out an experienced, rated pilot to bring your aircraft safely to GJT, then fly it back to you when service is complete. Whether it's an annual inspection, a tricky problem that needs a creative solution, or just some routine squawks you'd like fixed, give us a call. We'll be happy to discuss your needs, explain our approach and provide you with a price quote. No job is too small, and we invite you to experience our unique approach to servicing your aircraft. Business hours, call 970-257-9175 or, for problems after hours, don't hesitate to call:
