AD/P68/11 Amdt 1 - Rudder Control Pulleys at Fuselage Frame No. 3 - Inspection

Overview

The Civil Aviation Regulations 1998, as amended, represent a critical framework governing the safety and operational standards of civil aviation in Australia. Enacted by the Parliament of Australia, these regulations aim to ensure that all civil aviation activities adhere to the highest safety standards, thereby protecting the public and maintaining the integrity of the aviation industry. One specific area addressed by these regulations is the issuance of airworthiness directives, such as AD/P68/11, which targets specific safety issues within certain aircraft models. The policy objective behind these directives is to proactively manage and mitigate risks associated with identified safety concerns, ensuring the continued airworthiness of aircraft and the safety of passengers and crew. The particular airworthiness directive AD/P68/11 pertains to the Partenavia P68 Series aeroplanes, mandating inspections of rudder control pulleys at fuselage frame number 3. This directive responds to incidents where frame 3 has been found cracked and rivets working at the mounting brackets for rudder control cable pulleys. The directive extends the compliance times for initial and repeat inspections to address these issues, ensuring that any potential structural failures are identified and rectified in a timely manner. The directive is applicable to all models P68 and P68B with serial numbers referenced in Partenavia Service Bulletin No. 40, Revision 1, or subsequent revisions.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, specifically Part 39 - 105 concerning the Schedule of Airworthiness Directives, governs the maintenance and inspection of certain aircraft within the Australian aviation industry. This particular regulation, AD/P68/11 Amendment 1, applies to all Partenavia P68 and P68B series aeroplanes with serial numbers referenced in Partenavia Service Bulletin No. 40, Revision 1, or any subsequent revisions of that bulletin. The directive mandates specific inspections of rudder control pulleys at fuselage frame number 3, a response to incidents where frame 3 was found cracked and rivets were working loose at the mounting brackets of the rudder control cable pulleys. Compliance with this directive is essential to ensure the continued airworthiness of the affected aircraft, with detailed inspection requirements provided in the referenced document. The regulation extends compliance times for initial and repeat inspections, thereby impacting the maintenance schedules of the specified aircraft models.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Airworthiness Directives (ADs) that must be followed for certain aircraft models, such as the Partenavia P68 Series Aeroplanes. The directive in question, AD/P68/11 Amendment 1, pertains to the rudder control pulleys at fuselage frame number 3, requiring an inspection (section 5/82). This directive applies to all models P68 and P68B with serial numbers referenced in Partenavia Service Bulletin (SB) No. 40 Revision 1, or those referenced in any subsequent issues or revisions of that bulletin. The document providing the details of this requirement is Partenavia SB No. 40, Revision 1, and it is noted that this directive is also referenced in RAI AD 78-181/P68-17. Compliance with this directive is as specified in the requirement document. The Civil Aviation Regulations impose several obligations on the parties or entities governed by them. For the Partenavia P68 Series Aeroplanes, operators must ensure that the rudder control pulleys at fuselage frame number 3 are inspected as per the guidelines set out in the applicable service bulletins. These inspections are critical to identify any potential issues such as cracks in the frame or working rivets, which could compromise the safety of the aircraft. Operators must maintain records of all inspections and any actions taken as a result of these inspections, ensuring ongoing compliance with airworthiness standards. Failure to comply with the ADs, such as AD/P68/11 Amendment 1, can result in serious consequences. Civil aviation regulations outline both criminal and civil penalties for non-compliance. Criminal penalties can include fines and imprisonment, reflecting the severity of neglecting safety directives that are critical to the operation of an aircraft. The maximum penalties can vary, but they are designed to ensure that compliance is taken seriously. Civil penalties may also include fines and other financial penalties, as well as potential orders from the court to rectify any non-compliance issues. These consequences are intended to enforce adherence to safety regulations and protect the public from the risks associated with non-compliant aircraft operations.
