Harry Demarest is the Managing Partner for DCG Aero.  Harry is a 30+ year veteran of the commercial aircraft industry and has worked in aircraft and propulsion engineering on F100, MD-80, 737, 747, 757, 767, 777, 787, DC10, MD11, and A300 aircraft.

Prior to his current role at DGC, Harry worked at Pratt & Whitney, American Airlines, and Alaska Airlines.  At Alaska, Harry served as Director of Engineering.  During his tenure, Engineering completed installation of Split Scimitar Winglets, the largest ever cabin re-fit in Alaska’s history, streaming content for WIFI,  prototypes for Nitrogen Gas Inerting, and the introduction of APU On-Demand ETOPS; all while maintaining the best on-time for performance of any North American carrier.  In addition, Harry developed the Safety Management System processes to allow Engineering to meet the recently released FAA requirements.

At American, Harry was Managing Director of Aircraft Engineering and Powerplant Engineering.  Under his auspices, Engineering removed over $200M of annual cost from maintenance, improved the yield on CF6-80, and 80C2 engines from as low as 500 cycles to typically over 3000 cycles., designed the installation modification for ABP for the 767 winglet STC, and introduced the 737-800 and CFm56-7 into service. 

Harry also used his Lean background and Six Sigma training to guide the transition of AA’s MD-80 heavy maintenance from a traditional production scheme to a moving line, which lowered check time from 22 to 15 days; a revenue increase of approximately $700,000 per C-check, with no added costs.  

At Pratt & Whitney, Harry worked on the certification programs for JT9D and PW4000 engines and directed the 150hr endurance certification test for the V2500 engine.
