Why Turboprop East?

Heritage & Trust — Over half a century of service since 1968, continuously evolving with the industry and maintaining FAA-certified standards.

Deep Specialization — We’re not a general shop: we specialize in turboprop and small business aircraft, particularly King Air, Citation, and the Avanti lines. This lets us do fewer things, but do them superbly. 

Location & Access — Nestled in the scenic Berkshires, yet only ~28 miles east of Albany, NY, we’re ideally placed for operators in New England, eastern New York, and beyond. Spacious facility, full parts inventory, responsive service. 

Full Lifecycle Support — From routine inspections to major modifications, STC work, pre-purchase evaluations, and import/export certificates — we handle the full spectrum so you get back flying faster.

At Turboprop East, we believe in blending technical strength with genuine customer care. Whether you’re a corporate operator, private owner, or regional fleet, we treat every aircraft as mission critical. Our team keeps your schedule in mind, and works hard so the details in maintenance, avionics, and parts never become roadblocks.
