An accident occurred with an AW169 helicopter, the root cause of which is still under investigation. While the helicopter was on a take-off phase at low forward speed, a loss of yaw control has been observed. As incorrect installation of the TRA might have been a factor, as a precautionary measure, Leonardo issued ASB 169-120 to provide instructions to check the installation of the TRA and, subsequently, ASB 189-213 with the same instructions, since AW189 helicopters have a similar design TR flight control system.
