2. Remove the external power system from the aeroplane or provide a means to ensure that an external power supply with reversed polarity cannot be connected to the electrical system of the aeroplanes.
3. Provide a clearly identified external earthing point for the attachment of ground connections in a conspicuous position, preferably on each main undercarriage assembly or on the nose gear.
4. Install 50 amp circuit breakers (B1, B2 and B3) in the alternator and battery main cables.
5. Correct and calibrate the magnetic direction indicator and install a deviation card in accordance with ANO Section 108.6.
6. (a) Identify the circuit and rating of all fuses.
(b) Provide adequately stowed spare fuses of the correct size and rating for each fuse which is capable of being replaced in flight. The number of spare fuses shall not be less than 20 per cent of the number of each rating.
7. Modify the cockpit placard adjacent to the static source selector to show the correct position of the selector for the alternate static source.
8. Modify the limiting speed placard to show speeds in knots IAS instead of knots CAS.
9. Delete the placard located between the fuel selectors relating to fuel cross feed.
10. Modify the marking of the fuel selectors in accordance with Partenavia SB No. 14, Rev 1. Applicable up to S/Nos 122 inclusive.
11. Install fireproof sealing for the gaps existing between the side and rear members of the engine bay firewalls to a scheme approved by the Secretary.
12. Inspect and replace as necessary all flexible hose assemblies carrying flammable fluids in the engine compartment with hose assemblies meeting the fire resistance standards of FAA TSO C53B Type C or D or render them fire resistant to that standard by fitting an approved fire sleeve.

SCHEDULE OF AIRWORTHINESS DIRECTIVES
13. Install a placard in the cabin specifying the periods during which smoking is prohibited.
Compliance: Item 1 - Within 100 hours time in service after 30 June 1976.
Items 2 to 13 - Before 30 September 1975.
Note: Re-certification is required against the amended Item 1 only.
Background: This directive has been amended to reflect the latest revision to Partenavia SB NO. 14 which is the subject of item 10 of the requirements. The applicability of the original Service Bulletin included all P68 and P68B aircraft. This was incorrect as aircraft from serial number 123 and up are fitted with three way fuel selectors and not four.
Overview
The Civil Aviation Regulations 1998, specifically within Part 39 - 105 under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, introduces amendments to ensure the continued safety and compliance of Partenavia P68 series aeroplanes. Enacted by the Australian Parliament, this legislation aims to address safety concerns and compliance issues identified in the operation of these aircraft. The policy objective is to mandate specific modifications to various components of the aircraft to enhance safety and operational standards, thereby mitigating potential risks associated with the identified issues. Compliance with these directives is mandatory, with specific timelines provided for the implementation of each requirement, ensuring that all affected aircraft meet the stipulated safety benchmarks.
This directive, which has undergone amendments to align with the latest revisions of Partenavia Service Bulletin No. 14, particularly addresses the need for accurate placarding and the installation of fire-resistant materials in the engine bay. The modifications encompass a range of safety enhancements, from the installation of fuses and circuit breakers to the provision of clear placarding and fireproof sealing. This legislative instrument underscores the Civil Aviation Safety Authority’s commitment to maintaining high safety standards within the aviation industry, ensuring that all aircraft meet stringent regulatory requirements designed to protect passengers and crew.
Scope and Application
The Civil Aviation Regulations 1998, Part 39 - 105, specifically pertaining to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives for Partenavia P68 Series Aeroplanes, outlines detailed pre-certification requirements for all model P68B aircraft. This legislation applies to aircraft manufacturers, operators, and maintenance providers who must adhere to specific modifications and safety standards to ensure compliance with Australian civil aviation regulations. These requirements are mandatory and must be implemented within the specified timeframes, which include modifications to the aircraft’s electrical systems, installation of safety placards, and enhancements to fire resistance in the engine compartment. The directive also necessitates corrective actions for placards and indicators to ensure accurate information is provided to pilots and ground crew. Compliance with these directives is essential for maintaining airworthiness and ensuring the safety of operations involving Partenavia P68 Series Aeroplanes within Australian airspace.
The directive applies geographically within the Commonwealth of Australia, affecting all P68B aircraft regardless of their location within the country. The amendments reflect updates to previous service bulletins, ensuring that the modifications align with current safety standards and technological advancements. Exclusions or exemptions from these requirements are not explicitly stated in the provided text, indicating that all applicable aircraft must comply. The applicability of these directives can be further extended or clarified through subordinate instruments, which may provide additional details or specifications regarding the implementation of these safety measures.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish Airworthiness Directives for the Partenavia P68 series aeroplanes, including model P68B. The directive mandates several modifications to ensure the safety and airworthiness of these aircraft. For example, Section 1 requires the installation of a 3 amp fuse in each field circuit between the "I" field terminal on the alternator and the junction point of the cable from the voltage regulator selector switch (AD/P68/2Amdt 2, Item 1). Additionally, Section 2 necessitates the removal of the external power system from the aeroplane or the implementation of safeguards to prevent the connection of an external power supply with reversed polarity to the aircraft’s electrical system (AD/P68/2Amdt 2, Item 2). Other requirements include installing clearly identified external earthing points, installing specific circuit breakers, correcting and calibrating the magnetic direction indicator, and ensuring adequate spare fuses are available (AD/P68/2Amdt 2, Items 3 to 7). Modifications to placards and markings are also required, along with fireproofing measures and the installation of a placard prohibiting smoking in the cabin (AD/P68/2Amdt 2, Items 8 to 13).
Compliance with these directives is mandatory for the specified modifications. For instance, Item 1 requires compliance within 100 hours of time in service after 30 June 1976, while Items 2 to 13 must be completed before 30 September 1975. Re-certification is necessary only for the amended Item 1. These deadlines and requirements are intended to ensure that the necessary safety improvements are implemented in a timely manner, thereby maintaining the airworthiness of the aircraft.
Failure to comply with the provisions of these Airworthiness Directives can lead to serious consequences. Civil Aviation Regulations 1998 do not specify particular offences, penalties, or consequences for non-compliance within the directive itself, but non-compliance could result in the aircraft being deemed unairworthy. This could lead to enforcement actions by the Civil Aviation Safety Authority (CASA), including potential fines, operational restrictions, or the grounding of the aircraft until the required modifications are completed. The penalties for non-compliance are not explicitly stated in the directive, but they can be severe, reflecting the critical nature of maintaining airworthiness standards to ensure public safety.
