AD/ML-M5/2 - Control Column Chain and Engine Controls - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form the fundamental regulatory framework for civil aviation within Australia. Part 39 of these regulations includes specific airworthiness directives designed to ensure the safety and reliability of aircraft in operation. One such directive, AD/ML-M5/2, pertains to the Maule M-5 Series Aeroplanes, specifically targeting the inspection of the control column chain and engine controls. This directive was introduced to address potential safety issues associated with these components in certain model series. The policy objective is to mandate regular inspections to prevent failures that could compromise flight safety. Compliance with these directives is essential for maintaining the airworthiness of affected aircraft, thereby ensuring the safety of passengers and crew. The directive applies to all Maule M-5-210C aeroplanes with serial numbers ranging from 6001C to 6050C and all Maule M-5-220C aeroplanes with serial numbers from 5001C to 5037C. The requirement is for these inspections to be conducted within 100 hours of time in service following 31 October 1978. The directive references Maule Service Letter No. 29 as the document detailing the necessary inspection procedures. By adhering to this directive, operators of these aircraft ensure that critical components are regularly examined and maintained, thereby enhancing overall aviation safety.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/ML-M5/2, pertains to the inspection of control column chains and engine controls for Maule M-5 Series aeroplanes, particularly those of the model M-5-210C with serial numbers ranging from 6001C to 6050C and the model M-5-220C with serial numbers from 5001C to 5037C. This regulation applies to the relevant aircraft and mandates that inspections be conducted within 100 hours of time in service following 31 October 1978. The directive is part of the broader Civil Aviation Regulations 1998, which are enforceable throughout the Commonwealth of Australia, ensuring compliance with safety standards set by the Civil Aviation Safety Authority. The directive does not explicitly mention any exclusions, exemptions, or thresholds beyond the specified models and serial numbers, and it is expected that compliance is achieved in accordance with the provided Maule Service Letter No. 29. The scope of this directive is specifically targeted to ensure the safety and airworthiness of the designated aeroplanes, reflecting the rigorous regulatory environment governing civil aviation in Australia.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically within Part 39 - 105, contains the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which includes directives pertinent to the Maule M-5 series aeroplanes. The directive AD/ML-M5/2 (10/78) focuses on the inspection of the control column chain and engine controls. This directive applies to all model M-5-210C aircraft with serial numbers (S/Nos.) between 6001C and 6050C, and all model M-5-220C aircraft with S/Nos. between 5001C and 5037C (section 10/78). The required compliance document is Maule Service Letter No. 29, and the inspection must be completed within 100 hours of time in service after 31 October 1978. This Airworthiness Directive imposes specific obligations on aircraft operators and maintenance personnel. It mandates that all specified aircraft undergo an inspection of the control column chain and engine controls by qualified personnel. The inspection must be performed in accordance with the procedures outlined in Maule Service Letter No. 29 to ensure that the components meet the safety standards set by CASA. The directive ensures that any detected issues are rectified before the aircraft is returned to service, maintaining the safety and airworthiness of the aeroplanes. Failure to comply with the requirements of this directive can lead to serious consequences. Under the Civil Aviation Act 1988 (Cth), non-compliance can result in the aircraft being deemed unairworthy, which could prevent the aircraft from being operated until the required inspections and repairs are completed. Additionally, CASA has the authority to issue fines or other penalties for non-compliance with Airworthiness Directives. The maximum penalties for such breaches can include substantial fines and, in severe cases, criminal charges for operators who knowingly allow non-compliant aircraft to be flown. Ensuring adherence to these directives is critical for maintaining the safety standards set by CASA.
