AD/CESSNA 208/25 Aileron Upper Quadrant
Carry-Through Cable Attachment 5/2009

Applicability:

Model 208 aircraft, serial numbers 20800001 through 20800415 and 20800417 through 20800419.

Model 208B aircraft, serial numbers 208B0001 through 208B1081, 208B1083 through 208B1215, 208B1217 through 208B1257, 208B1259 through 208B1305, 208B1307, and 208B1309 through 208B1310.

Requirement:

Modify the aileron carry-through cable attachment to the aileron upper quadrant with parts of improved design, in accordance with the Accomplishment Instructions in Cessna Caravan Service Bulletin CAB08-6 dated 27 October 2008, or later FAA approved revision.

Note:  FAA AD 2009-05-12 Amdt 39-15836 refers.

Compliance:

Within 100 hours time in service or 6 months after 7 May 2009, whichever occurs first.

This Airworthiness Directive becomes effective on 7 May 2009.

Background:

The FAA received reports of a “catch” in the aileron control system when the control yoke is turned.  The actions required by this Directive are intended to prevent the cable attach fitting on the aileron upper quadrant assembly from rotating and possibly contacting or interfering with the aileron lower quadrant assembly, which could result in limited roll control and reduced handling capabilities.
