COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Partenavia P68 Series Aeroplanes
AD/P68/29
Amdt 1
Elevator Trim Tab 1/89
Applicability: All P68 up to serial number 381 included. Requirement: Action in accordance with Partenavia SB 73 Rev 1.
Note: RAI AD 88-167 refers.
Compliance: Within 100 hours time in service after 20 July 1988.
Background: To reduce the flexibility of stabilator tabs with seven ribs or eight ribs, modification or replacement is required. This will increase control authority. Amendment 1 calls up Rev 1 of the Requirement document which may alleviate the action required for aircraft with more than 3500 hours T.I.S.
Overview
The Civil Aviation Regulations 1998, as amended, represent a comprehensive legislative framework for the regulation of civil aviation in Australia. Enacted by the Parliament of the Commonwealth of Australia, these regulations are designed to ensure the safety and efficiency of civil aviation operations within the country. One particular legislative instrument under this act, F2006B05356, addresses specific maintenance requirements for Partenavia P68 Series Aeroplanes to enhance their airworthiness. The policy objective behind this instrument is to mitigate potential safety risks associated with the flexibility of stabilator tabs, thereby increasing control authority and ensuring the safe operation of these aircraft. This directive, applicable to all Partenavia P68 aircraft up to serial number 381, mandates specific modifications to elevator trim tabs to meet airworthiness standards, aligning with broader safety objectives within the aviation sector.
This instrument is part of a broader schedule of airworthiness directives under Part 39 - 105 of the Civil Aviation Regulations 1998, highlighting the commitment of the Civil Aviation Safety Authority to maintain stringent safety standards. The requirement for compliance within 100 hours of time in service after 20 July 1988 underscores the urgency and importance of addressing these modifications to ensure the ongoing safety of the aircraft in question. The reference to Partenavia SB 73 Rev 1 and RAI AD 88-167 further situates this directive within a continuum of safety measures and industry standards, reinforcing the regulatory intent to uphold high safety benchmarks in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, mandate specific airworthiness directives that apply to the Partenavia P68 Series Aeroplanes, with a particular focus on those up to serial number 381. This regulation is intended to ensure the safety and control authority of these aircraft by requiring modifications to the elevator trim tabs, specifically addressing those with either seven or eight ribs. The directive is in compliance with Partenavia Service Bulletin 73 Revision 1 and references the RAI AD 88-167 for further context. Aircraft operators must adhere to these directives within 100 hours of time in service following 20 July 1988, unless the aircraft has accrued more than 3500 hours of time in service, in which case the amendment may provide an alternative to the required action. This regulation applies nationally across Australia and is enforced by the Civil Aviation Safety Authority. There are no stated exclusions or exemptions to these directives, and compliance is mandatory for the specified aircraft models within the outlined timeframe.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a detailed schedule of airworthiness directives pertinent to certain aircraft models. In this instance, AD/P68/29 Amendment 1 focuses on the Partenavia P68 Series aeroplanes, applicable to all aircraft up to serial number 381. The directive mandates compliance with Partenavia Service Bulletin 73 Revision 1, which references RAI AD 88-167 for further context. The primary requirement is to modify or replace the elevator trim tab to reduce its flexibility, particularly for aircraft with seven or eight ribs, in order to enhance control authority (Section 1/89). This action must be carried out within 100 hours of time in service following 20 July 1988.
The obligations imposed by this airworthiness directive are quite specific. Owners and operators of Partenavia P68 Series aeroplanes must ensure that the modifications or replacements are carried out in accordance with the detailed instructions provided in Partenavia Service Bulletin 73 Revision 1. This includes adhering to the timeline stipulated, which is within 100 hours of time in service after the specified date. Failure to comply with these directives may result in the aircraft being deemed non-airworthy, thereby prohibiting its operation until the required modifications have been completed.
In the event of non-compliance with AD/P68/29 Amendment 1, there are potential consequences for the parties involved. While the specific civil or criminal penalties are not detailed in the excerpt, it is clear that failure to adhere to the airworthiness directives can lead to significant operational restrictions. The aircraft may be grounded, and operators could face enforcement actions from the Civil Aviation Safety Authority (CASA). These actions could include fines, penalties, or other regulatory measures designed to ensure compliance with safety standards. The exact penalties and consequences would be detailed in other sections of the Civil Aviation Regulations 1998, but the overarching principle is that non-compliance can have serious ramifications for the safety and legality of operating the aircraft.
