AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/CA25/7 and issues the following AD under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
AD/CA25/7
Amdt 1
Aileron Hanger Ribs 9/2000 DM
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.
Amendment 1 is issued in response to a deteriorated aileron hanger rib found on a Skyfox CA25N aircraft that recently suffered an in-flight separation of the right hand aileron. This Directive requires further inspections of the aileron hanger ribs.
The original issue of this Airworthiness Directive became effective on 3 March 1998.

Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the issue of airworthiness directives through the Civil Aviation Safety Authority (CASA) which is tasked with ensuring that civil aviation in Australia meets internationally accepted safety standards. The regulations were enacted by the Parliament of Australia and are designed to maintain the highest levels of safety within the aviation industry. This legislative instrument, F2006B04838, serves as an amendment to an existing Airworthiness Directive (AD) AD/CA25/7, focusing on the structural integrity of Skyfox Aviation (Hedaro) CA25 Series aeroplanes. The policy objective behind this amendment is to enhance the safety of these aircraft by requiring mandatory inspections and testing of aileron hanger rib extensions to prevent potential in-flight failures. This proactive measure was introduced in response to an incident where an aileron hanger rib extension broke under minimal stress, leading to a significant safety risk. The amendment mandates that all applicable aircraft must undergo these inspections before further flight and at regular intervals thereafter, ensuring continued airworthiness and safety.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which applies to various aircraft within the Australian jurisdiction. This particular Airworthiness Directive (AD) applies to all CA22A/25, CA25, and CA25N aircraft, ensuring that these aircraft meet specific safety requirements. The directive mandates that all aileron hanger rib extensions be inspected and tested in accordance with the instructions provided in Skyfox Aviation Ltd Service Bulletin No. 24, Initial Issue, dated 27 February 1998. The compliance requirement necessitates that these inspections occur before any further flight after 2 August 2000, and subsequently at intervals not exceeding 100 hours or 12 months, whichever comes first. This Airworthiness Directive extends its application across the Commonwealth of Australia, reflecting CASA's commitment to maintaining the highest safety standards in civil aviation.
Key Provisions
The Airworthiness Directive (AD) AD/CA25/7 Amendment 1, issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998, applies to all CA22A/25, CA25, and CA25N aircraft. This directive revokes the previous AD/CA25/7 and mandates specific actions to address the identified safety issue. The directive requires that all aileron hanger rib extensions be inspected and tested in accordance with Skyfox Aviation Ltd Service Bulletin No. 24, Initial Issue, dated 27 February 1998. This action must be completed before further flight after 2 August 2000 and then at intervals not exceeding 100 hours or 12 months, whichever comes first.
The obligations imposed by this AD are clear and specific. Owners and operators of CA22A/25, CA25, and CA25N aircraft must ensure that the required inspections and tests of the aileron hanger rib extensions are performed. These inspections must adhere to the detailed instructions provided in the Skyfox Aviation Ltd Service Bulletin No. 24, Initial Issue. The directive mandates that the inspections be carried out before the aircraft can be flown again after 2 August 2000, and then at regular intervals not exceeding 100 hours or 12 months. Failure to comply with these requirements can result in serious safety implications and potential legal consequences.
Failure to comply with the provisions of this AD can lead to significant consequences. Specifically, if an aircraft is operated in violation of this directive, it may be deemed unairworthy. This could result in enforcement actions taken by the Civil Aviation Safety Authority (CASA), which could include grounding the aircraft until compliance is achieved. The AD itself does not specify criminal penalties but non-compliance can lead to administrative and civil penalties, including fines and enforcement actions, as outlined in other sections of the Civil Aviation Regulations 1998. The exact penalties may vary depending on the severity and circumstances of the non-compliance.
