e Unsafe Condition This AD was prompted by mandatory continuing airworthiness information MCAI
originated by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI
describes the unsafe condition as failure of the nose landing gear NLG actuator attachment lever and detachment from the NLG leg. The FAA is issuing this AD to detect and correct cracks in the NLG actuator attachment lever, which could result in restricted rudder travel with the NLG
retracted and reduced airplane control.
