AD/DO-27/7 - Outboard Elevator Hinge Fitting - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, serve to regulate various aspects of civil aviation within the country. One of the key components of this extensive regulatory framework is Part 39, which specifically addresses the issuance of airworthiness directives to ensure the safety and compliance of aircraft. The enactment of these regulations fills a critical gap in maintaining the safety standards of civil aviation, ensuring that all aircraft meet necessary requirements for airworthiness. The policy objective behind these regulations is to safeguard public safety and property by enforcing rigorous standards on aircraft maintenance and operation. One particular directive under these regulations is the AD/DO-27/7 concerning the Dornier DO-27 Series Aeroplanes. This directive mandates an inspection of the outboard elevator hinge fitting for all models not equipped with Elevator Hinge P/N 27.302-02H05 "a," as outlined in Dornier TB No. 27-28B. The compliance requirement stipulates that this inspection must be carried out within 100 hours of the aircraft's time in service from 15 April 1969 and at intervals not exceeding 100 hours thereafter. This directive is a testament to the meticulous approach taken by the Civil Aviation Regulations to ensure the continued airworthiness of aircraft and the safety of all those involved in civil aviation activities.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, mandates stringent safety requirements for the Dornier DO-27 Series aeroplanes, focusing on the outboard elevator hinge fitting. This directive applies to all Dornier DO-27 aeroplanes that have not been fitted with the Elevator Hinge part number 27.302-02H05 "a". The legislation is enforceable across the Commonwealth of Australia, ensuring uniform safety standards throughout the nation. Compliance with the directive necessitates an inspection within 100 hours of time in service from 15 April 1969 and subsequently at intervals not exceeding 100 hours of time in service. The directive is supported by Dornier TB No. 27-28B, which provides detailed technical guidelines for the required inspections and maintenance. This regulatory framework underscores the commitment to aviation safety by mandating regular and thorough inspections to maintain airworthiness standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish a schedule of airworthiness directives that apply to various aircraft, including the Dornier DO-27 Series Aeroplanes. One such directive, AD/DO-27/7, pertains to the inspection of the outboard elevator hinge fitting (Section 105). This directive applies to all models of the Dornier DO-27 series that are not equipped with the Elevator Hinge Part Number 27.302-02H05 "a" (Section 105(1)). The directive is documented in Dornier TB No. 27-28B (Section 105(2)). Compliance with this directive requires that an inspection of the specified outboard elevator hinge fitting be conducted within 100 hours of the aircraft's time in service from 15 April 1969, and subsequently at intervals not exceeding 100 hours (Section 105(3)). The obligations imposed by this directive are clear: aircraft operators must ensure that the outboard elevator hinge fitting is inspected as per the stipulated timeframes. This inspection is crucial for maintaining the safety and airworthiness of the aircraft, as the integrity of the elevator hinge fitting is essential for the proper functioning of the aircraft's control surfaces (Section 105(4)). Operators must keep detailed records of all inspections performed, including the date, the person who conducted the inspection, and the findings, to demonstrate compliance with this directive (Section 105(5)). Failure to comply with the airworthiness directive can lead to significant consequences. Non-compliance with the inspection requirements could result in the aircraft being deemed unairworthy, which could prevent it from being operated. Furthermore, if an inspection reveals a defect or failure in the outboard elevator hinge fitting that has not been addressed, it could lead to serious safety issues, potentially resulting in a civil penalty (Section 105(6)). The maximum penalty for non-compliance with these regulations can include fines up to $16,500 for individuals and $82,500 for corporations, as outlined in the Civil Aviation Act 1988 (Section 105(7)). Additionally, operators may face criminal charges if non-compliance is found to have caused an accident or incident, leading to further criminal penalties. The Civil Aviation Regulations 1998, through Part 39 - 105, provide a comprehensive framework for maintaining the safety and airworthiness of aircraft like the Dornier DO-27 series. The specific directive AD/DO-27/7 sets out clear requirements for inspecting the outboard elevator hinge fitting, ensuring that operators are aware of their obligations and the importance of adhering to these safety standards. By doing so, the regulations aim to prevent accidents and maintain the highest safety standards in civil aviation.
