Background: The FAA received a report that a piece of the left wing inboard foreflap came off during a landing approach and penetrated the fuselage.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, is a comprehensive set of rules designed to ensure the safety and efficiency of civil aviation within Australia. Part 39 of these regulations, particularly the Airworthiness Directives, addresses specific safety concerns and requirements for various aircraft models, including the Boeing 747 series. The directive AD/B747/202, issued on 6 September 1999, was introduced in response to a reported incident where a piece of the left wing inboard foreflap detached during a landing approach and penetrated the fuselage. This directive aims to mitigate such risks by requiring a thorough visual inspection of the foreflap outboard sequence carriage attachment fitting and mandates corrective actions if any discrepancies are found. The objective is to ensure continued airworthiness and safety of the specified Boeing 747 models, aligning with international standards set by the Federal Aviation Administration (FAA).
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to a detailed inspection and maintenance requirement for Boeing 747 series aeroplanes. The legislation mandates a one-time detailed visual inspection of the foreflap outboard sequence carriage attachment to identify any discrepancies, including missing, loose, or migrated shims, and loose fasteners. This directive applies to specific models of Boeing 747 aircraft, namely the 747-100, 747-200B, 747-200F, 747-200C, 747SR, 747-100B, 747-300, 747-100B SUD, 747-400, 747-400D, and 747-400F, and covers line numbers 1 through 1,116. The compliance requirement must be met within 1,500 landings after 17 June 1999, or before 17 December 2000, whichever occurs first. The directive becomes effective from 17 June 1999, and the compliance is expected to address safety concerns following a reported incident where a piece of the left wing inboard foreflap detached during landing and penetrated the fuselage.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, specifically Airworthiness Directive AD/B747/202, mandates a detailed visual inspection of the wing inboard foreflap sequence carriage attachment fitting for certain Boeing 747 series aircraft (section 1). This inspection is to detect any discrepancies such as missing, loose, or migrated shims, and loose fasteners. This requirement is applicable to models 747-100, 747-200B, 747-200F, 747-200C, 747SR, 747-100B, 747-300, 747-100B SUD, 747-400, 747-400D, and 747-400F, and specifically concerns aircraft within line numbers 1 through 1,116 (section 2). The inspection must be performed in accordance with Boeing Alert Service Bulletin 747-57A2302 or Boeing Service Bulletin 747-57A2302 Revision 1. If any discrepancies are found during the inspection, corrective actions must be undertaken as specified in the relevant chapter of the Boeing Airplane Maintenance Manual (section 3).
Compliance with AD/B747/202 is required within a specific timeframe: the inspection must be completed within 1,500 landings after 17 June 1999, or before 17 December 2000, whichever comes first (section 4). The directive became effective on 17 June 1999. The requirement to comply within this timeframe ensures that the safety issue identified by the Federal Aviation Administration (FAA) is addressed promptly. The directive references FAA AD 99-05-02 Amdt 39-11051, indicating alignment with international standards and safety practices (section 5).
The obligations imposed by AD/B747/202 are significant. Operators of the specified Boeing 747 aircraft must ensure that the detailed visual inspection of the wing inboard foreflap sequence carriage attachment fitting is performed by qualified personnel and documented thoroughly. The corrective actions, if any, must be carried out according to the maintenance manual guidelines provided by Boeing. These steps are critical to maintaining the airworthiness of the aircraft and ensuring safety during operation.
Breaching the requirements set out in AD/B747/202 could result in serious consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against operators who fail to comply with the directive. Such actions can include fines, operational restrictions, or grounding of the aircraft until compliance is achieved. The specific penalties are determined based on the severity and impact of the non-compliance, but the overarching goal is to ensure that all aircraft maintain the highest safety standards.
