Applicability: All CA22A/25, CA25 and CA25N aircraft.
Requirement: Inspect and test all aileron hanger rib extensions in accordance with the Accomplishment Instructions of Skyfox Aviation Ltd Service Bulletin No. 24, Initial Issue, dated 27 February 1998.
Compliance: Before further flight after 2 August 2000; thereafter at intervals not to exceed 100 hours or 12 months, whichever occurs first.
This Amendment becomes effective on 2 August 2000.
Background: During an unscheduled inspection, an aileron hanger rib extension was broken with little downward pressure. The purpose of this Directive was to check the structural integrity of all aircraft in-operation which may be similarly affected.

The original issue of this Airworthiness Directive became effective on 3 March 1998.
