Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, serve as a comprehensive set of rules governing the safety and operation of civil aviation within Australia. One pertinent legislative instrument within this framework is the Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically addressing British Aerospace BAe 125 Series Aeroplanes. This instrument, F2006B10538, was introduced to address safety concerns related to the main landing gear door forward hinge fittings of BAe 125 series aircraft. The problem it sought to resolve included instances of in-service failures at the door jack attachment lugs, which posed a significant risk to aircraft safety. The policy objective is to ensure that these aircraft maintain airworthiness standards by requiring specific inspections and, where necessary, replacements of the hinge fittings to prevent potential failures.
The instrument is issued by the Civil Aviation Safety Authority under the authority of the Civil Aviation Act 1988, aiming to mandate regular inspections and timely replacements of the identified components to mitigate risks associated with structural integrity. By establishing clear compliance requirements and deadlines, the directive ensures that aircraft operators take the necessary actions to maintain the safety and airworthiness of their aircraft, thereby protecting both the crew and passengers.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, which includes the AD/HS 125/95 concerning the British Aerospace BAe 125 Series Aeroplanes' main landing gear door forward hinge fittings. This regulation applies to all BAe/DH/BH/HS 125 series aircraft post modification number 255640, which have specific main gear door forward hinge fittings that have exceeded a certain number of landings. The directive mandates actions in accordance with BAe 125 Service Bulletin 32-218, referencing British Civil Aviation Authority AD 008-06-88. Compliance involves visual inspections and replacements of the specified hinge fittings, depending on the number of landings at a particular date, with a strict timeline for replacement and further flight prohibition if a crack is found. This regulation is applicable nationally within Australia and extends to all relevant aircraft operators and entities within the Commonwealth.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105 (subsequently referred to as the Regulations), specifically the Airworthiness Directive AD/HS 125/95, pertains to the British Aerospace BAe 125 series aeroplanes. The directive focuses on the main landing gear door's forward hinge fittings. The applicability extends to all BAe/DH/BH/HS 125 series aircraft post Mod 255640 with specific main gear door forward hinge fittings (P/N 25-WS3787 to 25-WS3788 and their derivatives) that have exceeded 6000 landings. The main requirement under this directive is to perform actions in accordance with BAe125 Service Bulletin 32-218, with a reference to British CAA AD 008-06-88.
The obligations imposed by the Regulations include specific inspection and replacement protocols for the mentioned hinge fittings. For fittings that had exceeded 6000 landings by 3 November 1988, a visual inspection must be carried out as defined in Paragraph 2B of BAe SB 32-218 within 100 landings following 3 November 1988. Subsequent inspections should occur at intervals not exceeding 300 landings until the fittings are replaced, with a mandatory replacement by 30 June 1989. For fittings that had surpassed 8000 landings by the same date, replacement must occur before 31 December 1988. Additionally, any cracked fittings identified must be replaced before the aircraft is flown again.
Failure to comply with these directives can lead to severe consequences. The Regulations do not explicitly state the offences or penalties for non-compliance; however, non-compliance with Civil Aviation Regulations can result in significant civil and criminal penalties. Such penalties may include fines, imprisonment, or both, depending on the severity of the breach and the discretion of the court. The potential civil and criminal repercussions underscore the importance of adhering strictly to the stipulated requirements to ensure the airworthiness and safety of the aircraft.
