H-S Tool & Parts

What H-S Tool & Parts does

H-S Tool & Parts Inc. (HS Tools) is a privately held Canadian aerospace maintenance, repair, and overhaul (MRO) specialist founded in 1974 and headquartered in Richmond, British Columbia, with a US shipping and distribution presence in Blaine, Washington. The company focuses on the repair and overhaul of aircraft component parts for helicopter and turbine engine platforms, offering over 400 proprietary FAA/Transport Canada approved repair procedures that enable salvage of parts others would consider unrepairable. Its service portfolio spans seven in-house capabilities: repair development, inspection (CMM, fluorescent penetrant inspection per ASTM E 1417, magnetic particle inspection per ASTM E 1444), precision machining, grinding, plating (hard chrome, sulphamate nickel, electroless nickel, cadmium, silver), thermal spray metallizing (plasma, thermo, wire), and welding, executed by accredited tool and die makers with superalloy and exotic material expertise.

The company's revenue model is built on two streams: professional services revenue from customized component repair and overhaul priced per repair specification, and a rotable exchange pool that allows operators to exchange worn parts for rebuilt units, providing a cost-effective alternative to new OEM parts. H-S Tool & Parts holds regulatory certifications from Transport Canada (Approved Maintenance Organization for Components, NDT/Welding, and Distribution), EASA, Canada's Controlled Goods Program (valid through 2029), and Joint Certification Program, as well as OEM approvals from Rolls-Royce (RR300, C20, C28, C30, C47, 250 series), Honeywell, Bell, Sikorsky, General Electric, and CRC/Ozark. Its customer base is drawn from aerospace operators and MRO facilities operating commercial helicopter and turbine engine platforms, alongside defense and government aviation programs requiring certified repair under controlled goods regulations.

The company engages customers through direct sales channels including a comprehensive online catalog searchable by OEM platform, dedicated phone support with US toll-free and Canadian/international lines, and a field sales motion focused on North American aerospace operators. Go-to-market is enabled by the regulatory and OEM approval set, which functions as the primary trust signal and qualification gate for aerospace buyers. Headcount, revenue scale, and ownership structure are not disclosed in available sources.
