STAKEHOLDER COMMITTEE RECOMMENDS COLLABORATIVE INDUSTRY-GOVERNMENT INITIATIVE TO FACILITATE UNLEADED AVGAS TRANSITION

The UAT ARC found that a “drop-in” unleaded replacement fuel that can be seamlessly deployed for the existing fleet of aircraft is not available and that alternative fuels require significant assessment to ensure safety. In addition, to date there is not a market-driven reason to move to a replacement fuel due to the limited size and specialty nature of avgas, combined with the safety, liability and expense involved with a complex approval and deployment process. After its own review, the FAA “found the information and recommendations contained in the report to be very helpful in understanding the challenges of transitioning the piston engine-powered fleet to an unleaded avgas.”

The UAT ARC provided several recommendations and detailed action plans necessary to facilitate the development and fleet-wide deployment of an unleaded avgas. The key recommendations include:

• Implementation of a “Fuel Development Roadmap” that identifies specific milestones in the avgas development process and information needed to support assessment of the viability of candidate fuels in terms of impact on aircraft and production infrastructure and economic considerations.
• Centralized testing of candidate unleaded fuels at the FAA William J. Hughes Technical Center funded by government and industry in-kind contributions to generate qualification and certification data.
• Establishment of a collaborative industry-government initiative, referred to as the Piston Aviation Fuels Initiative (PAFI), to coordinate implementation of the UAT ARC recommendations to develop and deploy an unleaded avgas with the least impact on the existing piston-engine aircraft fleet.

If recommendations are fully implemented and funded, up to 10 unleaded aviation gasoline candidates could be evaluated. Within five years, the process would generate qualification and certification data to support fleet-wide certification of the most promising candidates. The actual transition to an unleaded avgas depends directly upon the level of impact upon the existing fleet and fuel production infrastructure. Therefore, the UAT ARC recommendation includes up to six years for additional assessment and testing that may be necessary to facilitate a transition such as implementing approvals across the entire fleet, certification of modifications and changes to fuel production infrastructure.

The PAFI would rely on technical expertise from all stakeholders within industry and government. Centralized FAA testing of candidate fuels is essential to support an efficient fleet-wide qualification and certification, which is necessary for safety. Although this is just one part early in the process, this investment by the FAA will minimize the total cost of transition for both the FAA and industry. It also helps overcome significant market barriers, which will facilitate industry investments needed toward the development of unleaded avgas and transition of the entire fleet of aircraft.

This is a joint statement from the general aviation industry members of the Avgas Coalition, which includes the Aircraft Owners and Pilots Association, the Experimental Aircraft Association, the General Aviation Manufacturers Association, the National Air Transportation Association, and the National Business Aviation Association. This group applauds the FAA’s leadership in establishing and participating in the UAT ARC and believes the recommendations are critically important to facilitating a transition to an unleaded avgas that works for the entire fleet. It will give owners and operators added confidence that the industry is on the right path to a solution.

The general aviation associations will continue to work with the FAA in developing, implementing and funding an unleaded avgas plan that includes the key elements outlined in the ARC’s report that are necessary to facilitate the development and deployment of an unleaded avgas with least impact upon the existing piston-engine aircraft fleet.

The full FAA UAT-ARC report, including specific recommendations and detailed action plans, is available from the FAA Web site.
