ASTM International Workshop Will Cover Means of Compliance for eVTOL Aircraft Certification

Safety standards organization ASTM International is hosting a virtual workshop on the means of compliance for eVTOL aircraft. The free-to-attend event on November 2 will focus on the compliance gaps that aircraft developers need to fill to meet ASTM’s AC433 standards.

According to ASTM’s administrative committee on means of compliance for eVTOL aircraft (AC433), the workshop’s main objective is to provide insight into how gaps in industry consensus standards are being filled as new technology and aircraft configurations are developed for urban air mobility and other applications. It is primarily intended for developers of eVTOL and electric-powered conventional takeoff and landing aircraft.

The workshop will consider the rewriting of Airworthiness Standards: Normal Category Airplanes (14 CFR Part 23 Amendment 64), Certification Specifications for Normal-Category Aeroplanes (CS-23 Amendment 5), and related industry consensus standards that have been accepted through ASTM standard F3264. These amendments cover ASTM means of compliance accepted respectively by FAA for its Part 23 type certification and by EASA for its CS-23 rules.

The AC433 committee consists of stakeholders from industry and government and academic institutions representing the following four ASTM committees: light sport aircraft (F37), unmanned aircraft systems (F38), aircraft systems (F39), and general aviation aircraft (F44). More technical information is available from workshop co-chairs Anna Dietrich ( and Tom Gunnarson ( Dietrich is a cofounder of eVTOL developer Jump Aero, co-executive director of the Community Air Mobility Initiative, and a member of the eVTOL committee of the General Aviation Manufacturers Association. Tom Gunnarson is a former FAA transportation industry analyst who is now the lead for regulatory affairs for eVTOL developer Wisk, the joint venture by Boeing and Kitty Hawk.

ASTM International is a not-for-profit body that has been working for more than 120 years to advance safety and public health standards across multiple industries. It integrates consensus standards developed by volunteer technical experts from around the world. The group has developed more than 12,500 standards and has more than 30,000 members.
