A network of on-call and scheduled line maintenance services

Line MaintananceSTS Line Maintenance services commercial and regional airlines operating out of U.S. based major airports. We can do it, and do it efficiently, because we've established a network of dependable maintenance technicians who know your aircraft and understand the AOG cost of delayed response. 

Skilled mechanics stand ready to handle RON maintenance, turn-around checks, non-routine discrepancy reports and ground equipment maintenance with scheduled service or on-call. Either way, you get priority one status. 

STS Line Maintenance also offers a five-minute response time to most ramp areas. Our main concern is, and always has been, the safety of your aircraft. We mandate compliance with all corporate, federal and local safety standards, and we make certain work is not just done but done correctly. 

A reputation for safety standard compliance, prompt service and highly capable mechanics…that’s why we were the recipient of the FAA Diamond Award for Maintenance Training.
