Summary

We propose to supersede Airworthiness Directive (AD) 2001-12- 18, for certain CASA Model CN-235 series airplanes. AD 2001-12-18 currently requires modification of the rigging of the engine control cable assembly and replacement of either the entire engine control cable assembly or a segment of the control cables. Since we issued AD 2001-12-18, we have received reports of new occurrences of cable disruption on a certain part number; the disruption is caused by microcracks along the cable surface. This proposed AD would retain the requirements of AD 2001-12-18. This proposed AD would also require repetitive replacements of each power lever and condition lever Teleflex cable with a new or serviceable part and would remove airplanes from the applicability. We are proposing this AD to prevent fatigue of the engine control cables, leading to breakage of the cables, which could result in reduced controllability of the airplane.
