Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide the legal framework for ensuring the safety of civil aviation in the country. One of the specific legislative instruments under this act, F2006B04826, pertains to the Skyfox Aviation (Calair/Hedaro) CA21 and CA22A series aeroplanes, aiming to address potential safety issues identified in these aircraft models. This instrument, issued by the Civil Aviation Safety Authority (CASA), seeks to rectify an unsafe condition identified in the aileron hanger ribs of these aircraft through mandatory inspections and testing. The policy objective is to maintain and enhance the airworthiness of the aircraft, ensuring they meet the necessary safety standards before further flights. The directive was introduced in response to an incident where an aileron hanger rib extension broke with minimal downward pressure, necessitating a thorough inspection to prevent similar occurrences in other aircraft of the same series.
Scope and Application
This Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 (CAR 1998) by the Civil Aviation Safety Authority (CASA) applies specifically to all CA21, CA22, and CA22A series aircraft. It mandates the inspection and testing of aileron hanger rib extensions in accordance with the instructions provided by Skyfox Aviation Ltd in their Service Bulletin No. 24, Initial Issue, dated 27 February 1998. The directive requires these actions to be carried out before further flight after 2 August 2000 and subsequently at intervals not exceeding 100 hours or 12 months, whichever occurs first. This directive was issued in response to an incident where an aileron hanger rib broke under minimal pressure and another incident involving an in-flight separation of the right-hand aileron on a Skyfox CA25N aircraft, underscoring the necessity for enhanced safety measures. The AD is applicable across the Commonwealth of Australia and its provisions are enforceable as per the CAR 1998, with any amendments or further directives potentially extending or modifying its scope.
Key Provisions
The Airworthiness Directive (AD) AD/CA21/7 Amendment 1 (AD/CA21/7Amdt 1) applies to all CA21, CA22, and CA22A series aircraft (Applicability section). The directive mandates that the inspection and testing of all aileron hanger rib extensions be carried out in accordance with the Accomplishment Instructions provided in Skyfox Aviation Ltd Service Bulletin No. 24, Initial Issue, dated 27 February 1998 (Requirement section). This inspection must be completed before further flight after 2 August 2000 and then at intervals not exceeding 100 hours or 12 months, whichever comes first (Compliance section).
The AD imposes specific obligations on the operators and owners of the affected aircraft. Primarily, they are required to conduct the necessary inspections and tests of the aileron hanger rib extensions to ensure that these components meet the safety standards outlined in the AD. This involves following the instructions set forth in Skyfox Aviation Ltd Service Bulletin No. 24. Operators and owners must ensure that the inspections are performed by qualified personnel and that any identified issues are rectified before the aircraft is returned to service.
Failure to comply with the AD could result in significant consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against operators or owners who do not adhere to the requirements of the AD. Potential penalties for non-compliance can include fines, suspension or revocation of airworthiness certificates, and other regulatory actions. The exact penalties depend on the severity and frequency of the non-compliance, but they can be substantial, reflecting the importance of ensuring the continued airworthiness and safety of the affected aircraft.
