The Sikorsky S-61 helicopter has been the backbone for heavy utility industries such as Oil & Gas and Forestry for years. The S-61 seats up to 30 passengers and its versatility makes it a perfect fit for utility roles.

Heli-One has provided MRO services on the S-61 for over 40 years with some of the most experienced technicians in the industry.  We maintain a large inventory of used, serviceable S-61 parts allowing us to lower costs and reduce turnaround times while maintaining quality.  Heli-One also offers by-the-hour maintenance support, as well as lease and exchange units.

We perform S-61 Base Maintenance activities in Vancouver, Canada and Stavanger, Norway and with our extensive catalogue of STCs we can confidently keep your S-61 mission ready.
