COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Piper PA-42 (Cheyenne III) Series Aeroplanes
AD/PA-42/16 Control Column Control Chain Retainer Clips 8/88
Applicability: PA42-720R, PA42-720 and PA42-1000 with Serial Numbers listed in the Requirement Document.
Requirement: Action in accordance with Piper SB 877.
Compliance: Prior to the next inspection for Maintenance Release issue after 11 August 1988.
Background: It has been determined that some retainer clips may be improperly installed. Loss of the retainer clip may cause control run disconnection and loss of aileron control.
Overview
The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B05982, is designed to address safety issues in civil aviation, particularly focusing on the maintenance and airworthiness of aircraft. This particular regulation, introduced by the Commonwealth of Australia, targets the Piper PA-42 (Cheyenne III) series aeroplanes and aims to rectify a specific safety concern identified in the control column control chain retainer clips. The regulation mandates adherence to Piper Service Bulletin 877 to ensure the proper installation of these clips, which, if improperly installed, could lead to the loss of aileron control and potential disconnection of the control run. This legislative instrument underscores the importance of timely compliance to mitigate risks associated with flight safety.
The regulation, enacted by the Australian Parliament, is aimed at ensuring that the specified Piper PA-42 aeroplanes maintain their airworthiness by adhering to the prescribed maintenance directives. The Piper PA-42 (Cheyenne III) series aeroplanes listed in the requirement document, namely PA42-720R, PA42-720, and PA42-1000, must have the control column control chain retainer clips installed correctly before the next inspection for maintenance release post 11 August 1988. The objective is to prevent any incidents related to the loss of aileron control, thereby enhancing the overall safety standards in civil aviation.
Scope and Application
The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 applies to the specified Piper PA-42 (Cheyenne III) series aeroplanes, namely those with serial numbers PA42-720R, PA42-720, and PA42-1000 as listed in the requirement document. This legislation mandates compliance with Piper Service Bulletin 877, which requires action to be taken concerning the control column control chain retainer clips. Specifically, the action must be completed prior to the next inspection for a Maintenance Release issue after 11 August 1988. This directive is necessary to address the risk of improperly installed retainer clips, which could lead to control run disconnection and loss of aileron control, thereby ensuring the airworthiness of the affected aircraft. The directive is applicable within the jurisdictional reach of the Commonwealth of Australia and applies directly to the specified aircraft models.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, detailing the requirements for maintaining the airworthiness of aircraft. In this context, AD/PA-42/16 pertains to the Piper PA-42 (Cheyenne III) series aeroplanes and addresses the issue of control column control chain retainer clips (section 8/88). The directive applies to specific models and serial numbers of the Piper PA-42 aeroplanes, namely the PA42-720R, PA42-720, and PA42-1000, with the serial numbers listed in the accompanying requirement document.
The primary requirement of this directive is that the action specified in Piper Service Bulletin 877 must be followed (section 8/88). This action likely involves inspecting, replacing, or otherwise ensuring the proper installation of the control chain retainer clips. The directive mandates compliance before the next inspection for a Maintenance Release issue following 11 August 1988. Essentially, operators of affected Piper PA-42 aeroplanes must ensure that the specified action is completed by this deadline.
The obligations imposed by this airworthiness directive are stringent and clear. Operators of the Piper PA-42 aeroplanes must adhere to the action outlined in Piper Service Bulletin 877, which likely includes a detailed inspection and corrective action procedure. This directive necessitates that the necessary work be completed and documented before the aeroplane undergoes its next scheduled inspection for a Maintenance Release. Failure to comply with this requirement could lead to significant safety implications, as the improper installation of retainer clips may result in the loss of aileron control.
Non-compliance with the provisions of AD/PA-42/16 could have serious consequences. Under the Civil Aviation Act 1988, failure to adhere to an airworthiness directive can lead to enforcement actions. Potential outcomes include fines and, in severe cases, criminal charges against the responsible individuals or entities. The exact penalties depend on the severity of the breach and the discretion of the court, but they can be substantial, reflecting the critical nature of ensuring aircraft airworthiness to protect public safety.
