AD/DC3/4 Reissue - Engine Section Throttle Control Rod - Replacement

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to regulate and ensure the safety of civil aviation in Australia. Specifically, Part 39 - 105 of these regulations provides a schedule of airworthiness directives, which are binding instructions issued by CASA to address safety issues in civil aircraft. One such directive, AD/DC3/4, pertains to the replacement of the engine section throttle control rod in Douglas DC3 Series aeroplanes, particularly those models fitted with Pratt and Whitney engines. This directive was introduced to address the need for ensuring the continued airworthiness and safety of these aircraft by replacing potentially faulty components that could compromise engine control. The policy objective behind the Civil Aviation Regulations 1998 and its associated directives is to maintain and enhance the safety standards of civil aviation in Australia. By requiring compliance with specific airworthiness directives, CASA aims to mitigate risks associated with aircraft operation and ensure that all aircraft meet necessary safety standards before being issued a Certificate of Airworthiness. The re-issuance of Directive AD/DC3/4 is a proactive measure to ensure that newly registered aircraft and those requiring Certificate of Airworthiness renewal adhere to these critical safety requirements.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertaining to the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Douglas DC3 Series Aeroplanes, applies to all models of DC3/C47 aircraft equipped with Pratt and Whitney engines. This legislation mandates that compliance with the requirements stipulated in Airworthiness Directive AD/DC3/4, concerning the replacement of the engine section throttle control rod, must be met before a Certificate of Airworthiness is issued or renewed. The regulation ensures that any aircraft entering the Australian aircraft register or undergoing a Certificate of Airworthiness renewal adheres to the safety standards outlined in this directive. Notably, the referenced documents, including Douglas SB (DC3) No. 219 Section V, CAA (US) AD 44-7-3, and ANO 105.1.16.1.5.4, are provided for informational purposes, as they are no longer mandatory. This directive ensures that all applicable aircraft meet the necessary safety criteria before being allowed to operate within Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, specify the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, including AD/DC3/4 concerning the Douglas DC3 Series Aeroplanes. Specifically, section AD/DC3/4 mandates the replacement of the engine section throttle control rod for all DC3/C47 aircraft models fitted with Pratt and Whitney engines (AD/DC3/4). This directive ensures that compliance is achieved before the issuance of a Certificate of Airworthiness. The applicability of this directive extends to aircraft newly added to the Register and those requiring a Certificate of Airworthiness renewal. The obligations under this directive require that the engine section throttle control rod in affected aircraft must be replaced according to the specifications provided in Douglas SB (DC3) No. 219 Section V, CAA (US) AD 44-7-3, or ANO 105.1.16.1.5.4. These referenced documents, while included for informational purposes, are not mandatory compliance requirements. The directive insists that the replacement be completed to meet airworthiness standards, ensuring that the aircraft is safe for operation before any Certificate of Airworthiness can be issued. Failure to comply with the requirements outlined in AD/DC3/4 may result in severe consequences. According to the Civil Aviation Regulations, non-compliance with an Airworthiness Directive can lead to various civil and criminal penalties. While the exact penalties are not specified in this directive, general provisions under the Civil Aviation Act 1988 may impose fines and imprisonment for serious breaches of aviation safety regulations. The severity of the penalty depends on the nature and extent of the non-compliance, with potential maximum penalties including substantial fines and lengthy imprisonment terms for individuals and organisations found guilty of violating safety directives.
