A Honda HA-420 HondaJet, registration N10XN, sustained substantial damage following a runway 27 excursion at Atlanta-Cobb County-Mc Collum Field (KRYY), Georgia, USA.
According to the pilot in command, the flight and approach to the airport were normal. After the airplane touched down on the runway, he applied the brakes, however, there was no braking action from the airplane and the pilot reported that there was no compression of the brake pedals. The pilot called out that they had "no brakes" and elected to pull the emergency brake. The airplane began to skid, the pilot released the emergency brake, and noted that the airplane was about 45° off centerline and continued to turn to the left. The airplane struck the grass apron next to the runway, completed a 180° turn, and came to rest the opposite direction of travel in the grass to the left side of the runway.
Examination of the wreckage by a Federal Aviation Administration inspector revealed that the right main landing gear collapsed, which resulted in substantial damage to the right wing. Furthermore, the left main landing gear tire was located about 225 ft from the main wreckage.
Examination of the airplane discrepancy log revealed that the left main landing gear tire was replaced the morning of the accident due to a discrepancy the pilot wrote up the day before the accident, which stated the left main landing gear tire was “worn beyond [the] thread cords.”

The same aircraft was involved in an incident back in 2018 at DeKalb-Peachtree Airport (KPDK). It veered off runway during landing and came to a stop in the grass.
