COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 767 Series Aeroplanes
AD/B767/95 Leading Edge Slat System 4/97
Applicability: All Model 767 series aircraft.
Requirement: Inspect in accordance with the technical requirements of FAA AD 96-25-18 Amdt 39- 9861.
Note: Boeing Alert Service Bulletin 767-27A0137 refers.
Compliance: Unless already accomplished, before the accumulation of 10,500 total hours time in service, or within 500 hours time in service after 27 March 1997, whichever occurs later; thereafter at the intervals specified in the requirement document.
This airworthiness directive becomes effective on 27 March 1997.
Background: The FAA received reports of skewed panels of an outboard leading edge slat due to the failure of a corroded rotary actuator or the control rod. An undetected skewed slat panel could lead to control difficulty and result in slat structure damage.
Overview
The Civil Aviation Regulations 1998, specifically PART 39 - 105, introduces the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which includes AD/B767/95 concerning Boeing 767 series aeroplanes and their Leading Edge Slat System. This legislation was enacted to address the critical issue of potential skewed panels on the outboard leading edge slats, arising from the failure of corroded rotary actuators or control rods. The directive mandates inspections in accordance with the technical requirements outlined in FAA AD 96-25-18 Amdt 39-9861, and references Boeing Alert Service Bulletin 767-27A0137 for compliance. The directive was introduced to ensure the airworthiness of Boeing 767 aircraft by preventing control difficulties and structural damage that could result from undetected skewed slat panels. The objective is to maintain safety standards within civil aviation by enforcing these stringent inspection protocols.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the maintenance and operation of aircraft within Australia, including the requirement for adherence to airworthiness directives issued by the Civil Aviation Safety Authority. In the context of Boeing 767 series aeroplanes, Airworthiness Directive AD/B767/95 mandates inspections of the leading edge slat system in compliance with the technical requirements set out in FAA AD 96-25-18 Amdt 39-9861, as referenced by Boeing Alert Service Bulletin 767-27A0137. This directive applies to all Model 767 series aircraft and requires inspections to be performed before the aircraft accumulates 10,500 total hours of time in service, or within 500 hours of time in service after 27 March 1997, whichever is later, and then at specified intervals. Failure to comply with this directive could compromise the aircraft's safety, as undetected skewed slat panels due to a failure in the rotary actuator or control rod can lead to control difficulties and potential slat structure damage. This directive became effective on 27 March 1997, and its implementation is overseen by the Civil Aviation Safety Authority to ensure the highest standards of airworthiness are maintained across the industry.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, sets out the airworthiness directives for various aircraft types, including the Boeing 767 series aeroplanes. One such directive, AD/B767/95, pertains to the leading edge slat system of the Boeing 767 series aeroplanes. Section 105 of the regulations mandates that all Model 767 series aircraft must undergo an inspection in accordance with the technical requirements of FAA AD 96-25-18 Amdt 39-9861. This requirement is to ensure the integrity and functionality of the leading edge slat system, which is critical for the aircraft's flight characteristics and safety.
The obligations imposed by this airworthiness directive are stringent and must be adhered to by all operators of Boeing 767 series aircraft. Operators are required to inspect the leading edge slat system in compliance with the specified technical requirements. This inspection must be completed before the aircraft accumulates 10,500 total hours in service, or within 500 hours in service after 27 March 1997, whichever occurs later. The inspection must then be repeated at intervals as specified in the directive document. Failure to comply with these inspection requirements could potentially lead to significant safety risks, including the risk of skewed panels on the outboard leading edge slat due to the failure of a corroded rotary actuator or control rod.
In the event of non-compliance with the airworthiness directive, there are potential consequences that could include both civil and criminal penalties. Although the specific penalties are not detailed in the provided text, it is clear that adherence to these directives is mandatory. Civil Aviation Regulations often carry significant penalties for non-compliance, which can include fines and potential grounding of the aircraft until compliance is achieved. In more severe cases, criminal charges could also be pursued, leading to imprisonment and further financial penalties. Therefore, it is imperative that operators ensure strict compliance with the stipulated inspection intervals and technical requirements to avoid any legal repercussions.
