Applicability:

All Cresco 08-600 series aircraft.

Requirement:

Accomplish the inspections detailed in Pacific Aerospace Corporation (PAC) Service Bulletin SB/CR/033.

Note:  NZ CAA AD DCA/CRESCO/6B refers.

Within 100 hours time in service after 28 February 2010, unless already accomplished within the last 600 hours time in service, and thereafter at intervals not to exceed 600 hours time in service.

This Amendment becomes effective on 28 February 2010.

Background:

Cables have been detected in service with significant fraying at the location of the wing inboard rib fairlead.  This is an area not readily accessed during routine inspection.
