AD/PR/3 - Pitch Lock Support Sleeve - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, address the need for ensuring safety and compliance in civil aviation operations. Specifically, Part 39 - 107 of the Civil Aviation Regulations 1998, under the authority of the Civil Aviation Safety Authority, was introduced to maintain the airworthiness of aircraft components and systems. This legislation is crucial in closing gaps related to the maintenance and modification of aircraft parts to ensure they meet safety standards. The policy objective of this regulation is to mandate specific modifications to propellers in certain aircraft models to prevent potential failures that could compromise flight safety. The Civil Aviation Regulations 1998 provide a framework for issuing Airworthiness Directives, ensuring that aircraft operators and maintenance personnel adhere to the required safety protocols.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 107, pertains to the Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). This legislation applies to specific types of aircraft propellers, namely those installed on Fokker F27, Grumman G159, and Viscount 810 aircraft models. The directive mandates modifications to the pitch lock support sleeve as outlined in Dowty Rotol Service Bulletin No. 61-185 (Modification No. (c) VP 2032), Rev. 4. Compliance with these requirements is mandatory before an aircraft undergoes its next overhaul after 28 February 1966. The Act is applicable nationally across Australia, overseen by CASA, and extends its regulatory authority through subordinate instruments to ensure the safety and airworthiness of the specified aircraft types. This legislation does not explicitly state any exclusions, exemptions, or thresholds beyond the requirement for compliance post-overhaul after the specified date.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 107, which pertains to Airworthiness Directives, include provisions that require modifications to specific propellers used in certain aircraft models (s. 39-107). In this case, Airworthiness Directive AD/PR/3 targets variable pitch propellers made by Dowty Rotol. Specifically, it mandates the modification of the pitch lock support sleeve on certain propeller models installed on Fokker F27, Grumman G159, and Viscount 810 aircraft. This modification must be carried out before the next overhaul after 28 February 1966, as outlined in Dowty Rotol Service Bulletin No. 61-185 (Modification No. VP 2032), Revision 4. These regulations impose clear obligations on the parties involved, primarily aircraft operators and maintenance providers. Operators must ensure that their aircraft comply with the specified modifications before the next scheduled overhaul. Maintenance providers are required to perform the specified modifications according to the detailed instructions in the Dowty Rotol Service Bulletin. Failure to comply with these directives could result in serious safety implications, as non-compliance may lead to propeller malfunction or failure, potentially compromising the safety of the aircraft and its occupants. Non-compliance with the Civil Aviation Regulations and the specific requirements of Airworthiness Directive AD/PR/3 can result in significant legal consequences. The Act does not explicitly state maximum penalties but generally, violations of the Civil Aviation Regulations can lead to substantial fines and other regulatory actions. In severe cases, the Civil Aviation Safety Authority (CASA) may impose penalties up to $1.65 million for corporations and $330,000 for individuals, depending on the severity and nature of the breach. Additionally, non-compliance could result in the grounding of the aircraft until the required modifications are made, which can have significant operational and financial implications for the operators.
