AD/B767/84 - Off-Wing Escape Slide Door Mechanism

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes directives related to the safety and maintenance of aircraft. One such directive, AD/B767/84, pertains to the Boeing 767 series aeroplanes and addresses the issue of leakage from the door opening actuators of the off-wing escape slide mechanism. This legislation was enacted by the Commonwealth of Australia to ensure that all Boeing 767 series aircraft are compliant with the safety standards set forth by the Federal Aviation Administration (FAA) in the United States. The directive was introduced to rectify a gap in the existing safety requirements, as identified by reports of inadequate leakage prevention in the previously installed actuators. The policy objective is to enhance the safety of passengers and crew by ensuring that the escape slide mechanisms function correctly and reliably in emergency situations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to all operators of Boeing 767 series aircraft equipped with off-wing escape slides. This regulation mandates compliance with the technical requirements stipulated in FAA AD 95-08-11 Amdt 39- 9200, which was issued to address leakage issues identified in the door opening actuators of the off-wing escape system. Compliance necessitates the replacement of existing door opening actuators with improved versions as specified in the Requirement Document, with a compliance deadline set for 12 October 1995. The regulation extends its reach across the Commonwealth, enforcing these safety standards to ensure the airworthiness of Boeing 767 series aircraft within Australian airspace. The directive references Boeing Service Bulletin 767-25-0216 for further technical guidance. This legislative instrument does not explicitly state any exclusions or exemptions, thereby applying uniformly to all relevant aircraft operators.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (ADs) that mandate certain actions for the continued airworthiness of aircraft. For Boeing 767 series aeroplanes, AD/B767/84 pertains to the off-wing escape slide door mechanism (Section 1). This directive applies to all Model 767 series aircraft that are equipped with off-wing escape slides (Section 2). The primary requirement is that the action taken must comply with the technical specifications outlined in FAA AD 95-08-11 Amdt 39-9200 (Section 3). Additionally, Boeing Service Bulletin 767-25-0216 is referenced for further guidance (Section 4). The Civil Aviation Regulations impose specific obligations on the operators and maintainers of Boeing 767 series aircraft. These stakeholders must ensure that the technical requirements set out in FAA AD 95-08-11 Amdt 39-9200 are met. This includes replacing the existing door opening actuators of the off-wing escape system with new, improved actuators to prevent leakage from the actuators (Section 5). Compliance must be achieved by the revised effective date of 12 October 1995 (Section 6). The regulatory framework requires that all actions are documented and that any necessary modifications are performed by qualified personnel. Failure to comply with the provisions of this Airworthiness Directive can result in severe consequences. The Civil Aviation Regulations 1998 outline various penalties for non-compliance, which can include both civil and criminal liabilities (Section 7). The exact penalties are not specified in the provided text, but generally, violations of such directives can lead to fines, operational restrictions, and potential grounding of non-compliant aircraft. The severity of the penalties may depend on the extent of the non-compliance and any resulting safety risks. Operators and maintainers must take diligent steps to ensure adherence to these regulations to avoid such repercussions.
