COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Casa 212 Series Aeroplanes
AD/CASA/17 MLG Shock Absorber 3/95
Applicability: All Model C-212 aircraft.
Requirement: Action in accordance with the technical requirements of Spanish DGAC AD 07/94.
Note: CASA SB 212-32-38 refers.
Compliance: As specified in the Requirement Document with a revised effective date of 2 March 1995.
Background: The DGAC requires the incorporation of a modification which improves the attachment of the restrictor piston on the sliding tube in the MLG shock absorbers, by increasing from one to three the number of screw pins installed.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which governs the airworthiness of various aircraft. The regulation in focus here is AD/CASA/17, concerning the MLG (Main Landing Gear) shock absorber of Casa 212 Series Aeroplanes. Enacted in 1998 by the Commonwealth of Australia, this regulation aims to ensure that aircraft meet the necessary safety standards. The particular directive addresses a problem related to the attachment of the restrictor piston on the sliding tube in the MLG shock absorbers, aiming to enhance the structural integrity and safety of the aircraft by requiring an upgrade from one to three screw pins. This modification aligns with the technical requirements set forth by the Spanish Directorate General of Civil Aviation (DGAC) AD 07/94, with compliance noted as specified in the Requirement Document, effective from 2 March 1995. The policy objective behind this regulation is to maintain and improve the safety standards of civil aviation, ensuring the reliability and safety of aircraft operations within Australian airspace.
Scope and Application
The Civil Aviation Safety Authority (CASA) regulations, specifically under PART 39 - 105 of the Civil Aviation Regulations 1998, establish the requirements for the airworthiness directives concerning CASA 212 Series Aeroplanes. This legislation applies to all Model C-212 aircraft and mandates compliance with technical requirements outlined in the Spanish Dirección General de Aviación Civil (DGAC) AD 07/94. The requirement necessitates action to ensure the modification of the main landing gear (MLG) shock absorbers, which involves increasing the number of screw pins from one to three to enhance the attachment of the restrictor piston on the sliding tube. This modification must be carried out in accordance with the requirement document, with a compliance deadline specified as revised to 2 March 1995. Additionally, CASA SB 212-32-38 provides further reference and guidance on this safety directive. The geographic reach of these regulations is national, applying across all jurisdictions within Australia under the oversight of CASA.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, addresses the maintenance requirements for Casa 212 Series Aeroplanes. The regulation in focus, AD/CASA/17, pertains to the modification of the MLG (Main Landing Gear) shock absorbers. Section (3/95) of the directive applies to all Model C-212 aircraft and mandates compliance with the technical requirements set forth by the Spanish Directorate General of Civil Aviation (DGAC) in AD 07/94. CASA has cross-referenced this directive with their own Safety Bulletin CASA SB 212-32-38. The requirement is that the modification should be carried out as specified in the Requirement Document, with the compliance effective from 2 March 1995.
Under this directive, operators of the Casa 212 Series Aeroplanes must ensure that the modification to the MLG shock absorbers is completed by an authorised entity. The modification involves improving the attachment of the restrictor piston on the sliding tube, which is achieved by increasing the number of screw pins from one to three. This enhancement is crucial for maintaining the airworthiness of the aircraft, ensuring that the landing gear functions safely and effectively under various operational conditions. Operators are required to document the completion of this modification and maintain records that demonstrate compliance with the directive.
Failure to comply with the requirements stipulated in AD/CASA/17 may lead to severe consequences. If an operator fails to implement the mandated modifications to the MLG shock absorbers, this could result in the aircraft being deemed non-airworthy. Non-compliance could potentially lead to enforcement actions by CASA, which may include the imposition of fines, suspension of the aircraft's airworthiness certificate, or other regulatory penalties. The safety of passengers and crew could also be compromised if the modifications are not carried out, as the integrity of the landing gear system is critical to the overall safety of the aircraft during landing and ground operations.
The Civil Aviation Regulations 1998 enforce strict penalties for non-compliance with airworthiness directives. For serious breaches, the maximum penalty can include substantial fines and imprisonment for individuals responsible for the oversight of the aircraft. In cases where the failure to comply results in an accident or serious incident, the penalties can be even more severe, reflecting the gravity of the potential safety risks involved. Operators are therefore strongly advised to ensure that all modifications, including those specified in AD/CASA/17, are completed in a timely and accurate manner to avoid these severe repercussions.
