AD 96-12-01 Amendment 39-9643

This amendment adopts a new airworthiness directive (AD), applicable to certain Jetstream Model 4101 airplanes, that requires replacement of the flexible cables of the power and condition controls of the engines with new flexible cables. This amendment also requires installation of protective tape on the outside case of these flexible cables, and reidentification of the cables. This amendment is prompted by reports of stiff operation of the power and condition controls of the engines due to heat damage to and moisture contamination of the flexible cable. The actions specified by this AD are intended to prevent heat damage and moisture contamination to the flexible cable, which could result in stiff operation of the power and condition controls and subsequent reduced engine control.
