Overview

The Civil Aviation Regulations 1998, specifically under Part 39 – 105, were enacted to address the safety concerns associated with the operation of civil aircraft within Australian airspace. The regulations were introduced by the Australian Parliament to ensure the safety of civil aviation through stringent regulatory oversight, thereby filling the gap left by the need for detailed safety directives specific to aircraft types. One such safety directive, AD/B767/40, targets Boeing 767 series aeroplanes and mandates the re-routing of aft equipment, lavatory, and galley ventilation fan wire bundles to prevent potential fires caused by damaged wire bundles. This directive was issued following reports of arcing and burning from damaged wire bundles, which could lead to fires behind the aft cargo compartment wall. The policy objective of this directive is to ensure the safety of passengers and crew by minimising the risk of fire hazards due to electrical faults. The Civil Aviation Safety Authority, under the authority granted by the Civil Aviation Act 1988, has implemented this directive to address an identified safety risk. Compliance with the directive is crucial, as failure to adhere to these standards could compromise the airworthiness of the aircraft and endanger lives. The directive specifies that the re-routing of the wire bundles must be completed prior to a specified date to ensure that all Boeing 767 series aeroplanes meet the required safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning Airworthiness Directives, apply to all Boeing 767 series aeroplanes. The regulation mandates that these aircraft must adhere to particular safety measures, including the re-routing of aft equipment/lavatory/galley ventilation fan wire bundles along the frame assembly at station 1540 as specified in Boeing ASB 767-21A0074. This requirement is a direct response to incidents of arcing and burning caused by damaged wire bundles, which have led to charred insulation blankets and pose a significant fire risk behind the aft cargo compartment wall. Compliance with this directive is crucial to mitigate the potential for damage to the wire bundles and to ensure the safety of the aircraft and its occupants. The directive must be implemented prior to 6 September 1991, ensuring that all affected Boeing 767 series aeroplanes are updated to meet the specified safety standards.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically section 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for Boeing 767 series aeroplanes. One such directive, AD/B767/40, pertains to the re-routing of aft equipment/lavatory/galley ventilation fan wire bundles. This directive applies to all Boeing 767 series aeroplanes as specified in the requirement document. The re-routing of these wire bundles must be carried out along the frame assembly at Station 1540, in accordance with Boeing ASB 767-21A0074. This requirement is underscored by FAA AD 90-08-13, which further highlights the urgency and importance of the directive. The directive was issued in response to a report of charred insulation blankets aft of Station 1540, which was caused by arcing and burning of damaged wire bundles. Failure to comply with this directive could result in significant safety risks, including the potential for a fire behind the aft cargo compartment wall. Compliance with the AD/B767/40 directive imposes specific obligations on the operators and maintainers of Boeing 767 series aeroplanes. They must ensure that the aft equipment/lavatory/galley ventilation fan wire bundles are re-routed along the frame assembly at Station 1540 as specified in Boeing ASB 767-21A0074. This must be done in accordance with the requirements outlined in the directive, and the work should be completed before the compliance date of 6 September 1991. The directive necessitates that all relevant parties take proactive measures to inspect and, if necessary, re-route the wire bundles to prevent any potential fire hazards. Proper documentation of the compliance work must be maintained to ensure that the aeroplanes meet the airworthiness standards set forth by CASA. Failure to comply with the requirements of AD/B767/40 can result in serious consequences, including both civil and criminal penalties. Non-compliance with airworthiness directives is considered a breach of the Civil Aviation Regulations 1998. Such breaches can result in penalties under the Civil Aviation Act 1988, which may include substantial fines and, in severe cases, imprisonment. The exact penalties are determined based on the severity of the breach and the extent of the non-compliance. Operators and maintainers are expected to adhere strictly to the directive to avoid any legal repercussions and to ensure the continued airworthiness and safety of the Boeing 767 series aeroplanes.
