Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as a comprehensive framework to regulate and ensure safety within the civil aviation industry. This legislation, which is periodically updated through legislative instruments such as the one referenced here, addresses gaps and problems in maintaining airworthiness and safety standards for aircraft. One such legislative instrument is F2006B05272, issued under the Civil Aviation Regulations 1998, which pertains specifically to Cessna 207 Series aeroplanes. This instrument was introduced to address specific safety concerns related to the wing flap actuator ball nut assemblies in these aircraft models. The policy objective is to enhance aviation safety by mandating the inspection and, where necessary, the replacement of these components to prevent potential operational hazards. The compliance requirements outlined ensure that affected aircraft are modified or placarded appropriately before further flights, thereby mitigating risks associated with the identified safety issues.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to the Cessna 207 Series aeroplanes with serial numbers as detailed in Cessna SL SE76-25. This legislation mandates that specific inspections and modifications be carried out on the wing flap actuator ball nut assemblies of these aircraft. The requirements outlined in the legislation are to ensure that the P/N C301002-0101 or P/N C301002-0102 wing flap actuators are inspected for a date stamp code. If the date stamp code is OH, HH, WH or ZH, a placard must be installed near the flap control indicating "FLAP EXTENSION PROHIBITED" until the necessary modifications are completed. Additionally, affected wing flap actuator ball nut assemblies must be replaced as per the guidelines provided in Cessna SL SE76-25. Compliance with these directives must be achieved before further flight after 28 January 1977, with particular emphasis on the installation of the placard within a specific timeframe and the replacement of the actuator assemblies within 100 hours of time in service after the same date.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an Airworthiness Directive (AD) that applies to the Cessna 207 Series Aeroplanes. This AD, identified as AD/CESSNA 207/12, pertains to the inspection and potential replacement of wing flap actuator ball nut assemblies (section 3/77). The directive is applicable to Model 207 aircraft with specific serial numbers as detailed in Cessna Service Letter SE76-25. The requirements under this directive include an inspection of the wing flap actuator (sections 1 and 2) and, if necessary, the installation of a placard and replacement of the actuator's ball nut assembly (section 3).
Section 1 of the directive requires an inspection of the wing flap actuator for a specific date stamp code. Section 2 mandates the installation of a placard reading "FLAP EXTENSION PROHIBITED" if the date stamp code on the actuator is OH, HH, WH, or ZH. This placard can be removed once the requirements of section 3 are met. Section 3 necessitates the replacement of affected wing flap actuator ball nut assemblies in accordance with Cessna Service Letter SE76-25. Compliance with sections 1 and 2 must occur before further flight after 28 January 1977, while compliance with section 3 must be achieved within 100 hours of time in service after the same date.
The obligations imposed by this AD on the parties governed by it include ensuring that the specified inspections are performed and any required placards are installed or replacements are made within the stipulated timeframes. Operators and owners of the affected Cessna 207 Series Aeroplanes must adhere to these directives to maintain airworthiness standards. Non-compliance with the requirements could result in the aircraft being considered unairworthy, leading to potential grounding and regulatory action.
The AD also includes potential consequences for non-compliance. While specific penalties are not detailed within the text of this directive, non-compliance with Civil Aviation Regulations can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions could include fines, administrative penalties, or other regulatory measures. Additionally, operating an aircraft that does not comply with airworthiness directives can result in civil liability for any incidents or accidents that may occur due to the non-compliance.
