AD 2001-26-13 Amendment 39-12579

This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-7 airplanes. This AD requires you to inspect the landing-gear emergency- extension cable for damage and replace if necessary; verify the correct installation of the bowden-cable conduit clamp and correct if necessary; and modify the temperature-control lever mechanism. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to prevent the malfunction of the emergency landing-gear extension system. Insufficient clearance between the temperature-control lever mechanism and the landing-gear emergency- extension cable could result in damage to the emergency landing gear extension cable, or the cable could get caught on the temperature control lever. Damage to, or interference with, the landing-gear emergency-extension cable could lead to a malfunction of the emergency landing-gear extension system.
