Archer Completes Challenging Battery Pack Drop Tests for FAA Certification

Archer Aviation Inc., a leader in the development of electric vertical takeoff and landing (“eVTOL”) aircraft, today announced the successful completion of rigorous battery pack drop testing conducted at a National Institute for Aviation Research lab. This marks a significant milestone in the development of the company’s proprietary electric propulsion system for its Midnight aircraft in what is seen as one of the most difficult tests to pass for an eVTOL aircraft, putting Archer in a strong position to successfully
complete this same test in upcoming for-credit testing with the FAA.

Over the course of this week, Archer’s engineering and certification teams led Midnight’s
proprietary battery packs through three 50-foot drop tests simulating extreme impact scenarios.
Tested at varying states of charge, 0%, 30%, and 100%, the battery packs withstood the impact
without any signs of failure and, remarkably, continued to function properly.

This test is renowned within the electric aviation industry as one of the most challenging barriers
to certification, designed to ensure battery packs can safely endure significant impact. A pivotal
factor in the success of these tests is Archer’s choice to utilize cylindrical cells within Archer’s
battery proprietary battery pack design.

“Successfully passing the battery pack drop tests marks a pivotal moment that paves the way
for future ‘for credit’ certification testing with the FAA,” said Alex Clarabut, Archer’s Battery
Lead. “This accomplishment highlights our dedication to not just meeting, but exceeding safety
standards. It is a critical step towards our goal of ensuring that Midnight will be among the safest
aircraft in the skies. It’s a testament to our team’s relentless pursuit of innovation and
excellence, and we’re thrilled with the results that the battery packs not only passed the test, but
still functioned properly afterward.”

Archer’s goal is to transform urban travel, replacing 60–90-minute commutes by car with
estimated 10-20 minute electric air taxi flights that are safe, sustainable, low noise, and cost-
competitive with ground transportation. Archer’s Midnight is a piloted, four-passenger aircraft
designed to perform rapid back-to-back flights with minimal charge time between flights.
