AD/DHC-1/6 - Engine Mount Pick-Up Bolt - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide comprehensive regulations to ensure safety and efficiency in civil aviation. Within this legislative framework, Part 39 - 105, pertaining to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, addresses specific safety concerns for certain aircraft models. One such directive is AD/DHC-1/6, which pertains to the inspection of the engine mount pick-up bolt in De Havilland DHC-1 (Chipmunk) Series Aeroplanes. This directive was introduced to mitigate potential safety risks associated with the engine mount pick-up bolt, ensuring that it remains in compliance with safety standards at regular intervals, not exceeding 50 hours of time in service. The objective of this regulation is to enhance the safety of air travel by enforcing rigorous inspection and maintenance protocols.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directives under the Civil Aviation Regulations 1998, specifically targeting the De Havilland DHC-1 (Chipmunk) Series Aeroplanes, as part of its commitment to ensuring safety in aviation. The directive AD/DHC-1/6 mandates an inspection of the engine mount pick-up bolt for all Canadian models of the Chipmunk series. This inspection must be carried out at intervals not exceeding 50 hours of time in service, ensuring the structural integrity and operational safety of these aircraft. The directive applies to all owners and operators of the specified aircraft models within the Commonwealth of Australia, extending CASA’s regulatory oversight to maintain high safety standards in civil aviation. The directive is referenced against specific technical standards, including DH (Canada) TNS, Series “C”, No. 39, Issue 2, and ANO 105.1.14.15.6.1, which provide the necessary technical guidance for compliance. This legislation underscores the importance of adhering to stringent safety protocols to prevent potential mechanical failures and ensure the safe operation of aircraft.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, includes a schedule of airworthiness directives pertaining to De Havilland DHC-1 (Chipmunk) series aeroplanes. Section AD/DHC-1/6 pertains to the inspection of the engine mount pick-up bolt. This directive applies to all Canadian models of the De Havilland DHC-1 series aeroplanes. The applicable documents for compliance are either DH (Canada) TNS, Series “C”, No. 39, Issue 2, or ANO 105.1.14.15.6.1. The requirement is to inspect the engine mount pick-up bolt at intervals not exceeding 50 hours of time in service. Under these regulations, operators of De Havilland DHC-1 series aeroplanes are obligated to adhere to the specified inspection intervals for the engine mount pick-up bolt. This ensures that the aircraft remains airworthy and safe for operation. Compliance involves following the detailed procedures outlined in the DH (Canada) TNS, Series “C”, No. 39, Issue 2, or the ANO 105.1.14.15.6.1. These documents provide the technical specifications and guidelines necessary for conducting the required inspections. Failure to comply with these airworthiness directives may result in significant consequences. The regulations impose strict obligations on operators to ensure that the necessary inspections are carried out at the specified intervals. If an operator fails to adhere to these requirements, they risk compromising the safety of the aircraft and its occupants. Non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The potential penalties for breaching these regulations can include fines, suspension of the aircraft’s operating certificate, or other regulatory actions deemed necessary to ensure compliance and maintain safety standards. The Civil Aviation Regulations 1998 also provide for specific penalties for non-compliance with airworthiness directives. While the exact penalties are not detailed in the provided text, it is clear that the consequences of failing to adhere to these requirements can be severe. Typically, penalties for breaches of such regulations can include substantial fines and potential imprisonment for individuals responsible for the oversight of the aircraft. Additionally, the aircraft itself may be grounded until compliance is achieved, which can have significant operational and financial repercussions for the operator.
