FAA Proposes Learjet 60 Anti-skid AD

A proposed Learjet 60 airworthiness directive is prompted by a high-speed rejected takeoff caused by all four main landing gear (MLG) tires blowing out during the takeoff roll. It would require installing new rigid hydraulic tube assemblies to the MLG struts and a new MLG squat switch bracket, modifying the MLG squat switch wire harness, modifying the MLG anti-skid wheel transducer electrical wire harnesses and other substantial corrections. It aims to prevent failure of the braking system or adverse operation of the spoiler and thrust reverser system due to external damage, particularly from tire failure, which could result in loss of control of the airplane.
