Our Services

Timberline Helicopters provides utility aviation services. Using proven aircraft, highly experienced crews, a late model ground support fleet, and a "can-do" attitude we endeavor to exceed customer expectations whatever the project. If you need something or someone moved by helicopter, Timberline Helicopters can accomplish the mission anytime and anywhere.

Firefighting

Growing from a solid foundation of providing firefighting helicopters to the US Forest Service, as well as state agencies in the USA, Timberline has grown to support firefighting operations around the world. To support this growth, our team has built an understanding of the logistics required for operations in remote and austere environments. Utilizing modern aircraft, custom designed firefighting equipment, and highly experienced crews, we can often provide more water, more accurately, to the ground firefighter than larger aircraft. Whatever the mission, we’re there.

Powerline Construction/Maintenance

From initial project survey to final inspection and continuing maintenance throughout the lifespan of utility infrastructure, Timberline has the equipment and experience required. This includes providing heavy lift helicopters for 500kV transmission tower construction in remote areas, pole replacement in-set, wire pulling, marker ball installation and replacement, bird diverter installation, mid span wire repairs, and Human External Cargo operations. Our pilots are known throughout the industry for their skill and “on the bolts” accuracy that is required for the safe completion of projects, especially while personnel may be working hundreds of feet above the ground, handling loads weighing up to 8,000 pounds. In addition to our pilots, we employ highly experienced linemen who are familiar with helicopter construction and maintenance to ensure that operations are completed quickly and safely.

Ski Lift Construction

Ski Lifts are built where it snows, naturally, but usually in locations that feature extreme terrain and/or altitude, a combination of factors which massively affects aircraft performance and stability. Timberline has participated in the building or replacement of more ski lifts in the Western United States than all other companies offering this service combined. Our pilots and riggers are often involved with the ski lift builder early on in the design phase of a new machine to ensure that each component is designed and built to a weight that can be safely delivered at the altitudes and temperatures required. In 2018, our operations went global when we completed a ski lift installation at Falls Creek, Victoria, Australia. Our focus on this industry has prompted us to keep at least one aircraft available during the summer months for ski lift and other construction work when most other operations concentrate on firefighting operations and thus may not be available.

Logging

Helicopter logging is an environmentally friendly way to extract valuable timber from areas that are inaccessible or cannot be disturbed. Timberline Helicopters began as a helicopter logging company, and we have many thousands of hours of experience with all types of logging projects. As the population moves further into the wildland urban interface, helicopter logging has become a preferred method of reducing the fuel loading to prevent catastrophic fires from burning homes and buildings. We have completed these types of projects in Washington, South Dakota, and California, and provided consulting services for the setup and administration of these projects. In 2015, our logging operations were transferred to Timberline Logging Enterprises, LLC.

Heavy Lift

Lift, move, place, or drop. Timberline has experience with many unique projects. Among these, our team has installed air handlers on top of 50 story buildings in highly congested areas, transported bronze statues in the mountains, worked on antennas over 700ft tall, surgically removed trees piece by piece from backyards, and dropped payloads from over 5,000ft to test parachute systems. For aerial transport of loads weighing up to 8,000lbs, we have the expertise to complete projects efficiently and safely.

Maintenance Services

Since 2013, Timberline has operated FAA Part 145 certificated repair station L0QR604L. Our current capabilities include the Schweizer 300, Bell UH-1, Kaman K-Max, Sikorsky UH-60, and MD-500/530F. In 2019 we added Pitot Static and Transponder certification to the services we offer.

International Operations

In December of 2016, Timberline was the first civil company to export and operate the UH-60 helicopter when one of our aircraft and its crew traveled to Australia to aid in bushfire fighting operations. Since then we have continued that support and in 2019/2020 assisted, with two UH-60 helicopters, in battling the worst fire conditions in recorded history in Australia. Also in 2019/2020, we provided the first civil UH-60 helicopter services in Chile. Principal operations were for initial attack operations carrying a 780 gallon (3,000L) bucket and a crew of 11 firefighters. Our logistics support team has developed a unique understanding of how to export these aircraft with proper U.S. Department of State approval and then support them in austere conditions while maintaining excellent dispatch reliability.

Supplemental Type Certificate Development

The team at Timberline is always looking for ways to make utility helicopters better and safer. In 2018, our sister company, Timberline Aerospace, was launched to pursue development of several Supplemental Type Certificates, including Purge Fuel Collectors for the UH-60, 34.5 to 308 beam modification for the UH-60, and locking fuel caps. Please visit the Timberline Aerospace website for more information on these and more exciting STCs currently in development.

UH-60 Refurbishment/Type Certification

Timberline Helicopters, Inc. is a recognized leader in global utility helicopter external load operations. In 2016, we were granted Restricted Category Type Certificate #R00052SE by the Federal Aviation Administration. This allows us to do complete refurbishment and civil certification of our aircraft. Our support team understands how important dispatch reliability is when operating in an emergency services support role or supporting a multi-million dollar construction project. Each aircraft receives a complete inspection, de-painting, removal of excess military wiring and equipment, installation of civil radios and intercom systems, and a thorough maintenance test flight process to ensure all systems are working at optimal capability. Also during this process, Timberline-developed and 3rd party modifications are incorporated to better serve the civil sector, including high visibility main rotor blades, external load control systems, purge fuel collectors, bubble window and visibility improvements for vertical reference operations, 34.5 to 308 beam structure modification, installation of T700-GE-701D engines, and Improved Durability Gearbox. This process typically takes between 4 and 6 months and involves 5,000 and 7,500 man hours to ensure the highest quality fleet.
