AD/EMB-110/7 Amdt 1 - Fire Detector Cable Terminals - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form a comprehensive framework designed to ensure the safety of civil aviation within Australia. Part 39 of these regulations, specifically Schedule of Airworthiness Directives, contains various directives aimed at maintaining and improving the airworthiness of aircraft. One such directive, AD/EMB-110/7 Amendment 1, addresses a critical safety concern identified in the Embraer EMB-110 (Bandeirante) Series Aeroplanes. This directive was introduced to address the problem of failures in the fire detector cable terminals, particularly the L"Hotellier terminals, which had been reported in several instances. By mandating modifications to these terminals with stronger replacements, the policy objective is to prevent potential fire hazards, thereby enhancing the overall safety of the aircraft in service. Compliance with this directive is required within 250 hours of time in service after 30 September 1982 for all affected models with serial numbers ranging from 110001 to 110340.

Scope and Application

The Embraer EMB-110 (Bandeirante) Series Aeroplanes Airworthiness Directive applies specifically to all models of EMB-110 with serial numbers ranging from 110001 to 110340. This legislation mandates compliance with Embraer Service Bulletin No. 110-26-002 Rev. 02 or Civil Aviation Authority AD 82-02-01, detailing the necessary modifications to the fire detector cable terminals to mitigate the risk of failure, which has been identified in several instances. Aircraft that previously complied with the initial issue of this directive must undertake further modifications to adhere to Amendment 1. Compliance with these airworthiness directives is required within 250 hours of time in service after 30 September 1982. This legislation underscores the importance of maintaining the structural integrity and safety of aircraft in the Commonwealth of Australia, governed by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, addresses the Airworthiness Directives concerning Embraer EMB-110 (Bandeirante) Series Aeroplanes. A critical section of this directive, AD/EMB-110/7 Amendment 1, pertains to the modification of fire detector cable terminals (Section 5/82). This directive applies to all models of the EMB-110 series with serial numbers ranging from 110001 to 110340. The compliance requirements are documented in Embraer Service Bulletin No. 110-26-002 Rev. 02 or CTA AD 82-02-01. It is essential to note that aircraft that have already adhered to the initial issue of this AD must undergo further modifications to meet the requirements of AD/EMB-110/7 Amendment 1. The compliance period mandates that the specified modifications be completed within 250 hours of time in service after 30 September 1982. The Civil Aviation Regulations impose several obligations on the operators and owners of the affected Embraer EMB-110 series aeroplanes. Primarily, they must ensure that the fire detector cable terminals are modified in accordance with the specified documents. This involves either following the instructions outlined in Embraer Service Bulletin No. 110-26-002 Rev. 02 or complying with CTA AD 82-02-01. Additionally, operators and owners must ensure that these modifications are completed within the stipulated timeframe of 250 hours of time in service after 30 September 1982. Failure to comply with these directives can result in the aircraft being deemed non-airworthy, which can lead to operational restrictions and potential grounding of the aircraft. Failure to adhere to the provisions outlined in AD/EMB-110/7 Amendment 1 can lead to serious consequences. Under the Civil Aviation Regulations, non-compliance with Airworthiness Directives is considered a breach of the regulations. Such breaches can result in civil penalties, including fines and potential legal action. The severity of the penalties can depend on various factors, including the extent of non-compliance and whether the non-compliance has led to any safety incidents or hazards. In extreme cases, persistent non-compliance could also result in criminal charges, leading to more severe penalties, including imprisonment. The specific penalties are not detailed in the legislative instrument but are generally commensurate with the gravity of the breach and its potential impact on aviation safety. The directive underscores the importance of addressing the failure of the "Hotellier" fire detector cable terminals, which the manufacturer has identified as a critical safety issue. The stronger replacement terminals specified in the directive are designed to mitigate the risk of failure and enhance the safety of the Embraer EMB-110 series aeroplanes. By mandating these modifications, the Civil Aviation Regulations aim to ensure that all affected aircraft meet the necessary safety standards, thereby protecting both the passengers and crew on board and maintaining the overall safety of the aviation industry. Operators and owners must therefore take the required steps to comply with the directive to avoid any legal or safety repercussions.
