With over 120 years of combined experience, the STS Line Maintenance Management Team has a long history of success in aircraft maintenance. We thoroughly understand the importance of having a line maintenance partner who’s there when you need them— and we prove it by giving our customers count-on-us confidence.               

Successful Partnerships...
In January 2009, a major airline relying on STS to handle all of its Philadelphia line maintenance achieved a 100% on time departure status with zero maintenance delays. And, another airline enjoyed the three-month early completion of a major modification project performed on half of their fleet during overnight service checks. Impressive maybe, but only two of our success stories.

Please call our 24-hour AOG response line to obtain a current listing of our line maintenance stations - (877) 707-5757. STS Line Maintenance is continually upgrading our locations to accommodate our customers’ needs. If you require maintenance support at a location we do not service, please notify us and we will consider adding that location to our current list of line maintenance sites.
