Overview
The Civil Aviation Regulations 1998, which were enacted by the Parliament of Australia, aim to ensure the safety and efficiency of civil aviation operations within Australia. This legislative instrument, specifically Part 39 - 105, pertains to airworthiness directives and is administered by the Civil Aviation Safety Authority (CASA). The problem or gap addressed by this particular directive is the need to inspect and modify the pilot and co-pilot windshield attach holes in certain Cessna 400 series aeroplanes to mitigate safety risks associated with potential windshield detachment. CASA issues such airworthiness directives to ensure compliance with international safety standards and to address specific safety concerns identified in aircraft operations. The policy objective is to maintain the highest standards of safety in the national airspace by enforcing mandatory inspections and modifications on affected aircraft to prevent accidents and enhance flight safety.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate that all Cessna 400 Series aeroplanes, including models 1978 through 1982 of the 414 variant and models 1977 through 1982 of the 421 variant with specific serial numbers, as well as model 425 with serial numbers within a defined range, must adhere to the specified airworthiness directives. This legislation applies to all aircraft with factory-installed windshields and ensures that these aircraft undergo a thorough inspection and necessary modifications concerning the pilot and co-pilot windshield attach holes. The compliance with these directives must be achieved within 50 hours of the aircraft being in service post 17 February 1984, with a restriction on maximum cabin differential pressure of 3.0 P.S.I. until compliance is confirmed. The regulations cover the Commonwealth of Australia and extend their reach to ensure that all applicable aircraft meet the stipulated safety standards.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, specifically under the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Cessna 400 Series Aeroplanes, sets forth requirements for certain Cessna aircraft models. The particular Airworthiness Directive (AD/CESSNA 400/49 Amendment 2) pertains to the inspection and modification of the pilot and co-pilot windshield attach holes in specific models of Cessna 400 Series Aeroplanes (section 1). The directive applies to Cessna 414 aircraft serial numbers 414A0001 through 414A0833, 414A0835 through 414A0851, 414A0853 through 414A0856, 414A0858, and Cessna 421 aircraft serial numbers 421C0273 through 421C1257, manufactured between 1978 and 1982, and Cessna 425 aircraft serial numbers 425-0002 through 425-0177, manufactured in 1977. The directive is specifically relevant to aircraft equipped with factory-installed windshields.
These regulations impose specific obligations on the owners or operators of the affected aircraft. They must ensure that an inspection and any necessary modification of the pilot and co-pilot windshield attach holes is completed within 50 hours of time in service after 17 February 1984. Until this compliance is achieved, the aircraft must be restricted to a maximum cabin differential pressure of 3.0 P.S.I. (Pounds per Square Inch). The directive references relevant documents such as Cessna S.L. ME77-5, Cessna S.L. ME83-33 REV 1, and Cessna S.L. PJ83-18 REV 1 for further details and guidance on compliance.
Failure to adhere to these Airworthiness Directives could result in civil or criminal penalties. The Civil Aviation Safety Authority may impose sanctions for non-compliance, including fines or other civil penalties, as stipulated by the Civil Aviation Act 1988. Additionally, if the non-compliance results in an aviation accident or incident, the responsible parties may face more severe criminal charges, including potential imprisonment, depending on the severity of the breach and its consequences. The exact penalties for specific breaches would be determined based on the relevant sections of the Civil Aviation Act 1988 and any other applicable legislation.
