Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Rubs between the pipe and the bulkhead may lead to premature wearing and finally rupture of the P3 air pipe. The loss of P3 air pressure would then force the fuel control system to idle which could have a detrimental effect in critical phases of flight. We are proposing this AD to prevent an uncommanded power loss, which could result in an emergency autorotation landing or accident.
