AD/DHC-8/38 ACM Delivery and Recirculation Duct Thermal Insulation
6/94
Applicability: DHC-8 aircraft, models and serial numbers as listed in the Requirement Document. Requirement: Action in accordance with Transport Canada AD CF-94-26.
Note: de Havilland SB 8-21-66 Revision B refers.
Compliance: Unless already accomplished, prior to 1 February 1996, or as indicated in part I.D of de Havilland Service Bulletins 8-25-89 through 8-25-93, whichever occurs later.
Background: The black thermal insulation blankets that are identified in AD/DHC-8/34, have also been found to be installed on the air cycle machine delivery and recirculation ducts in the aircraft rear fuselage.
Overview
The Civil Aviation Regulations 1998 (CAR 1998) represent a comprehensive regulatory framework designed to govern the safety and operational standards of civil aviation within Australia. This legislative instrument, enacted by the Australian Parliament, addresses various aspects of civil aviation safety, including the maintenance and airworthiness of aircraft. One particular directive, AD/DHC-8/38, pertains to the thermal insulation of the air cycle machine delivery and recirculation ducts in Bombardier (Boeing Canada/De Havilland) DHC-8 series aeroplanes. This directive was introduced to address safety concerns identified with the thermal insulation materials in these aircraft, specifically the black thermal insulation blankets that have been linked to potential hazards. The objective of this directive is to ensure compliance with Transport Canada AD CF-94-26, thereby mitigating risks associated with these materials through specified actions and timeframes, ultimately aiming to enhance the overall safety of air travel.
The enactment of CAR 1998 by the Australian Parliament reflects a commitment to maintaining rigorous safety standards in the aviation sector. This legislative instrument is integral in guiding the Civil Aviation Safety Authority (CASA) in its role of regulating and enforcing safety measures. The directive AD/DHC-8/38 is a critical component of this regulatory framework, targeting specific safety issues within the DHC-8 series aircraft. By mandating actions in accordance with Transport Canada's directives and referencing relevant service bulletins, CAR 1998 ensures that the identified thermal insulation issues are addressed effectively. The policy objective is clear: to prevent potential hazards and ensure that aircraft maintain the highest safety standards, thereby protecting passengers, crew, and the general public.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives for Bombardier (Boeing Canada/De Havilland) DHC-8 series aeroplanes. This legislation applies directly to the DHC-8 aircraft, encompassing the specific models and serial numbers as detailed in the Requirement Document. The directive mandates compliance with Transport Canada AD CF-94-26, referencing de Havilland Service Bulletin 8-21-66 Revision B, and requires actions to be taken regarding the thermal insulation blankets installed on the air cycle machine delivery and recirculation ducts in the aircraft's rear fuselage. Compliance must be achieved by 1 February 1996, or as specified in part I.D of de Havilland Service Bulletins 8-25-89 through 8-25-93, whichever date is later. The regulation's reach extends nationally, ensuring that all applicable aircraft within the Commonwealth of Australia adhere to these safety directives.
Key Provisions
The Civil Aviation Regulations 1998, under PART 39 - 105, specifically address the safety directives for Bombardier (Boeing Canada/De Havilland) DHC-8 series aeroplanes through the schedule of airworthiness directives. One such directive, AD/DHC-8/38, pertains to the thermal insulation of the air cycle machine (ACM) delivery and recirculation duct (section 105). This directive is applicable to DHC-8 aircraft with specified models and serial numbers, as outlined in the Requirement Document. The action required under this directive is to comply with Transport Canada AD CF-94-26, referencing de Havilland Service Bulletin 8-21-66 Revision B. Compliance must be achieved by 1 February 1996, or as indicated in part I.D of de Havilland Service Bulletins 8-25-89 through 8-25-93, whichever is later.
Under this Act, the obligations of the aircraft owners, operators, and maintenance providers are clear. They must ensure that the thermal insulation blankets identified in AD/DHC-8/34, which are also found on the ACM delivery and recirculation ducts in the aircraft’s rear fuselage, are properly addressed. This includes conducting the necessary inspections, modifications, or replacements as stipulated by the Transport Canada AD CF-94-26 and de Havilland Service Bulletins. The directive mandates that these actions be completed by a specified deadline to maintain the airworthiness of the aircraft.
Failure to comply with the requirements of the Civil Aviation Regulations, specifically under AD/DHC-8/38, may result in serious consequences. While the specific penalties are not detailed in the provided text, non-compliance with airworthiness directives can generally lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, suspension or revocation of the aircraft's certificate of airworthiness, or even criminal charges in severe cases. The exact penalties and consequences would be determined by CASA, in line with their regulatory powers and the severity of the breach.
