AD/ML-M4/14 Amdt 1 - Rudder Bar - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of Australia, serve to ensure the safety and efficiency of civil aviation within the country. The regulations encompass a wide array of safety standards and operational requirements, one of which is addressed in Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives. Specifically, Airworthiness Directive AD/ML-M4/14 Amendment 1 pertains to the Maule M-4 Series Aeroplanes, targeting a critical safety issue related to the rudder bar. This directive was introduced to address the problem of potential fatigue cracking in the rudder bar, which could compromise the aircraft’s control and safety. By mandating inspections and modifications in line with Maule Aircraft Corporation Service Bulletin No. 2, the policy objective is to reduce the risk of such failures and eliminate the need for repetitive special inspections, thereby enhancing the overall airworthiness and safety of the affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, as outlined in PART 39 - 105 of the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, specifically addresses the Maule M-4 Series Aeroplanes through Amendment 1. This legislation applies to all Maule M-4 models equipped with rudder bars that have not yet been modified in accordance with Maule Aircraft Corporation Service Bulletin No. 2. The directive mandates that an inspection and modification of the rudder bar must be conducted to mitigate the risk of fatigue cracking, which could potentially compromise flight safety. The requirement necessitates compliance within the next 100 hours of time in service after 31 October 1982. This regulation, issued under the authority of the Commonwealth of Australia, ensures that the specified modifications are implemented to maintain the airworthiness of these aircraft. The scope of the legislation is limited to aircraft models within the specified series and conditions, applying exclusively to those that have not yet conformed to the specified service bulletin. The Civil Aviation Regulations 1998, through this directive, extend their jurisdictional reach across the Commonwealth of Australia, ensuring that all operators of the affected Maule M-4 aeroplanes comply with the stipulated safety measures. The regulation does not explicitly state any exclusions or exemptions, indicating that the directive applies universally to the specified aircraft models within the Commonwealth. The application of this directive may be further refined or extended through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) for Maule M-4 Series Aeroplanes under the Civil Aviation Regulations 1998, specifically within Part 39 - 105. This directive (AD/ML-M4/14 Amendment 1) mandates specific actions concerning the rudder bar of affected aircraft models. According to section 10/82, the directive applies to all Maule M-4 Series aeroplanes equipped with rudder bars that have not yet been modified in line with Maule Aircraft Corporation Service Bulletin No. 2. The requirement stipulated in this AD is for the inspection and modification of the rudder bar as per the instructions outlined in the aforementioned service bulletin. The AD imposes certain obligations on the operators and owners of the affected aircraft. Specifically, they must ensure that the rudder bar is inspected and modified in accordance with the detailed instructions provided in Maule Aircraft Corporation Service Bulletin No. 2. This inspection and modification must be carried out within the next 100 hours of time in service after 31 October 1982. Failure to comply with this directive could result in the aircraft being deemed unairworthy, which could lead to significant operational disruptions and potential safety risks. The Civil Aviation Regulations 1998 outline the consequences for non-compliance with ADs. While the specific penalties for failing to comply with AD/ML-M4/14 Amendment 1 are not explicitly detailed in the provided text, generally, non-compliance with CASA directives can result in substantial civil and criminal penalties. Civil penalties can include fines, while criminal penalties can include imprisonment, reflecting the seriousness with which the authorities treat adherence to airworthiness standards. The exact penalties may vary based on the specific circumstances and the severity of the non-compliance.
