AD/ML-M4/2 - Attachment of Fuselage Fabric to Upper Windshield Channel - Modification

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which are instrumental in ensuring the continued airworthiness of aircraft. This legislative instrument was enacted to address gaps in aircraft maintenance and safety standards, providing clear directives for operators to follow. The policy objective is to maintain and enhance the safety of civil aviation within Australia, ensuring that aircraft are maintained to a high standard of airworthiness. The Civil Aviation Regulations 1998 were enacted by the Australian Parliament, reflecting the national commitment to stringent aviation safety regulations. This particular legislative instrument, AD/ML-M4/2, targets Maule M-4 Series Aeroplanes, specifically model M-4-210 with serial numbers 1001 to 1028, and mandates a modification to the attachment of the fuselage fabric to the upper windshield channel, as detailed in Maule Service Letter No. 8, to be implemented forthwith.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, including Attachment of Fuselage Fabric to Upper Windshield Channel - Modification, for specific aircraft models. This particular directive applies to all Maule M-4-210 aeroplanes with serial numbers (S/Nos.) ranging from 1001 to 1028, necessitating immediate compliance as indicated in Maule Service Letter No. 8. The regulation is comprehensive, covering the geographic and jurisdictional reach within the Commonwealth of Australia, ensuring that the specified modifications are uniformly applied across the nation. There are no stated exclusions, exemptions, or thresholds within the text provided, and the directive’s application may be further extended or restricted through subordinate instruments issued by CASA. The overarching aim is to maintain the safety and airworthiness of the affected aircraft within the Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, addresses the requirements for airworthiness directives, which are legally binding instructions issued by the Civil Aviation Safety Authority (CASA) to ensure the safe operation of aircraft. Within this context, Airworthiness Directive (AD) ML-M4/2 pertains to the Maule M-4 Series Aeroplanes, more precisely to models M-4-210 with serial numbers ranging from 1001 to 1028. This directive mandates a modification to the attachment of the fuselage fabric to the upper windshield channel (section 11/67). AD/ML-M4/2 requires that the specified Maule M-4-210 aeroplanes undergo a modification to the fuselage fabric attachment to the upper windshield channel. This modification is essential to ensure that the fabric is securely attached, reducing the risk of it coming loose during flight, which could potentially compromise the structural integrity of the aircraft and endanger safety (section 11/67). The compliance with this directive is mandated to be immediate, denoted as "forthwith" in the directive, indicating that the modification must be carried out without delay. Entities and individuals governed by this AD must ensure that the specified aircraft are inspected and, if necessary, modified to meet the directive's requirements. This includes verifying the aircraft's serial number falls within the specified range and ensuring the modification is performed by qualified personnel. The compliance obligations are stringent, as failure to adhere to the directive could result in non-compliance with airworthiness standards, potentially leading to grounding of the aircraft or other regulatory actions. In the event of non-compliance with AD/ML-M4/2, several consequences may ensue. Under the Civil Aviation Regulations 1998, non-compliance can be viewed as a breach of airworthiness requirements. This can result in administrative penalties, including fines and potential prosecution. The severity of penalties can vary, but they may include substantial financial penalties and, in severe cases, imprisonment for those found responsible for the non-compliance. It is imperative for the entities and individuals involved to adhere strictly to the AD to avoid these serious repercussions.
