The SilverSky Program, developed in 2008 by CD Aviation, is an online engine tracking service based on the idea customers should have access to their engine information anywhere at any time. CD Aviation Services has made improvements to SilverSky making it faster and more user-friendly. Logging into SilverSky provides customers a full spectrum view of current and past maintenance events, real-time progress status of all open work orders, comprehensive shop reports, and other relevant documentation. SilverSky makes it easy for TPE331 ag operators to access the history of their engine at any time from anywhere. CD Aviation Services is the only Part 145 Repair Station to offer this type of service.
