RTU-4000

Radio Tuning Unit

Regional Avionics Repair LLC has repair and overhaul capabilities for the Rockwell Collins RTU-4000.

Since 2010, this repair capability has given our customers an option to extend the life of these units by decreasing BER rates. Our proprietary repair methods give us the ability to save many sub-assemblies on the unit and decrease overall repair cost.

Our capabilities extend to maintain the HVPS, CRT, Front Panel and even the Tuning Switch. In every repair we replace components that are prone to fail targeting common problems to increase overall flight hour interval per visit. Many of current customers, both 121 operators and EASA enjoy the cost savings and reliability these repairs provide.
