Welcome to AS332 & H225 (EC225LP).

Mavana Air Support and Rainier Heli International.

We work together to refurbish and part out Super Puma Helicopters for the Civil Aircraft market. We currently have an AS332C model and 2 x H225's that we are working on. If you have an interest in either of these types please contact us at any time.


Established in 2007, Mavana Air Support manages the provision of engineering services for helicopter and fixed wing operators, primarily the repair and overhaul of aircraft components and the sourcing and supply of aircraft components and spare parts. Mavana Air Support partners with customers and suppliers to ensure customers receive a more cost effective and timely solution than could be achieved elsewhere, reducing the downtime of aircraft. With over 30 years of combined experience in both the global fixed wing and helicopter industries, Mr. Rhys Chamberlain, President and Licensed Aircraft Maintenance Engineer, and Mr. Leigh Cheyne, Director of Sales and Marketing, lead a team that prides itself on first-hand industry experience and technical expertise blended with a genuine commitment to providing responsive and reliable customer service.


The Halvorson family has been in the helicopter business since 1965. In 1992, Elling Halvorson and Lon Halvorson formed Rainier Helicopter Logging, Inc. We had success logging with a fleet of Huey’s, a Bell 214B, and a KAMAN K-1200 KMAX. When the bottom fell out of the timber market, we rapidly restructured Rainier and began looking internationally for work. In 1998, we changed our name to Rainier Heli-Lift, Inc. to fit our new mission. As the company continued to grow, so did the request for aircraft leasing. We pursued this business and currently have over 16 aircraft on lease and continue to operate the K-MAX for fire fighting and power line construction. In 2009 Rainier changed its name to Rainier Heli International to better reflect its global leasing business.
