Engine Maintenance Professionalism

“I want to take this opportunity to thank all the H+S team for an excellent effort to turn this APU around in a challenging timeframe. The early delivery of the APU has helped us as an operator to avoid a lot of disruption with an important 747 lease return next week. A great example of customer service.”
