Airwolf Aerospace LLC is a U.S.–based aerospace manufacturer specializing in certified helicopter parts that help lower operating costs for operators of civil and military rotorcraft. The company has been active in the aviation industry for over three decades, designing, producing, and certifying components that replace or improve on OEM helicopter parts.
✔ Who They Are
Airwolf Aerospace is headquartered in Middlefield, Ohio, United States, and operates as a privately held company focused on aviation parts manufacturing. The firm is lean — typically with fewer than 10 employees — but known within the helicopter community for its specialized products and certifications.
What Airwolf Aerospace Makes
1. PMA & STC Helicopter Parts
Airwolf produces a range of Parts Manufacturer Approval (PMA) and Supplemental Type Certificate (STC) components for many popular helicopter types. These parts are approved by the Federal Aviation Administration (FAA) and, in many cases, recognized by other civil aviation authorities like EASA (European Union Aviation Safety Agency) and Transport Canada.

Examples include:
- Tension-Torsion (TT) Straps – These are dynamic load-bearing components used in the main rotor hub systems of helicopters like the Bell 206 and Enstrom aircraft. Airwolf was the first to certify and improve the life limits on these straps, offering longer life and reduced costs over OEM units. (Airwolf Aerospace)
- Elastomeric Components – Bearings and dampers for rotor head assemblies, such as those developed for the Bell 407, are FAA-approved and stocked for immediate shipment. (Vertical Mag)
- Protective Solutions – Airwolf holds an STC for protective rotor blade tape that helps prevent leading-edge delamination on Robinson R22 and R44 helicopter blades, offering a more permanent solution than factory manual methods.
These parts often offer cost and performance advantages over original components, while still maintaining full certification for safety and airworthiness. (Airwolf Aerospace)
Certifications and Approvals
The pars of Airwolf Aerospace arts are not just aftermarket spares — many are FAA-certified under STC or PMA, which means they can legally be installed on certified aircraft without compromising safety standards. This level of approval also helps Airwolf parts gain acceptance in international markets through reciprocal agreements with other aviation authorities.
An example includes approval by the U.S. Defense Logistics Agency (DLA) as an authorized source for TT straps used on medium helicopters like the UH-1.
Benefits for Operators
Airwolf Aerospace’s certified parts are attractive for several reasons:
🔧 Reduced Operating Costs
Their products are engineered to be less expensive than many OEM replacements while meeting or exceeding airworthiness requirements.
📦 Better Availability
Airwolf keeps key parts in stock, helping operators avoid long lead times during repairs or maintenance. (Airwolf Aerospace)
✈ Improved Performance
Some Airwolf parts (like extended-life TT straps) are designed to improve durability and reduce maintenance cycles, leading to lower downtime.
Industry Role and Reputation
Although relatively small in size compared to big aerospace OEMs, Airwolf Aerospace has carved out a niche in helicopter components where certified aftermarket options provide real value. Operators of legacy Bell helicopters, Enstrom aircraft, and other rotorcraft often turn to Airwolf parts for cost savings without sacrificing safety.
The company continues to develop and certify new parts and STCs, expanding its portfolio and strengthening its presence in the rotorcraft maintenance and supply sector.
