About Mark

Mark started working part-time with York Aviation in 1992, rejoining the team in 2002 after serving as an Avionics Technician in the United States Navy.  While in the Navy, he graduated from aviation electronics schools at both NAS Millington, TN, and NAS Miramar, CA, and went on to troubleshoot F-14, F/A-18, S-3B, and E/A-6B avionics aboard the USS Dwight D. Eisenhower (CVN-69) during one overseas deployment cycle.  He earned the Navy-Marine Corps Achievement Medal, Aviation Enlisted Warfare Specialist designation, and logged one trap in a C-2 Greyhound.  Mark also has “big airport” FBO experience, having worked the busy ramps at both Las Vegas McCarran (KLAS) and Harrisburg International Airports (KMDT). So if you show up in anything from a Cessna 150 to a Boeing 767, you can be rest assured that Mark has the experience and knowledge to service your aircraft with precision and timeliness — to ensure you and your passengers have a pleasant stop in York, PA.

Greg Spicka

Line Service Technician

Greg owned his own motorcycle and ATV repair business for twenty-five years. In 2017, he was offered a position as operations manager at a local airport. As he had a background in aviation and missed that life, Greg closed up his repair shop and took it. Greg transformed the department from red to profitable, and excelled in customer service.  He retired in 2021 and began to help a friend working on Falcon jets from time to time while still dabbling in motorcycle repair. Seeing that York Aviation needed line help, Greg came out of retirement for some fun. Greg enjoys flying, riding motorcycles and ATVs, and is a published author.
