Overview

The Civil Aviation Regulations 1998, specifically under Part 39, establish a comprehensive framework to ensure the safety and airworthiness of aircraft within Australian airspace. Among these regulations, Airworthiness Directive (AD) AD/B737/177 was introduced in 2002 to address a safety concern related to the rudder pedal housings of Boeing 737 Series Aeroplanes, particularly models 737-600, -700, -700C, and -800 with line numbers 1 through 295. This directive was issued by the Civil Aviation Safety Authority (CASA) to mandate inspections and necessary repairs to prevent potential issues such as loss of free movement of the rudder pedals and reduced controllability of the aircraft, thereby enhancing flight safety. The directive is designed to align with the Federal Aviation Administration's (FAA) requirements, ensuring consistency with international safety standards.

Scope and Application

The Airworthiness Directive (AD) set forth in the Civil Aviation Regulations 1998 (CAR 1998) under Part 39, specifically section 105, pertains to the safety and airworthiness of Boeing 737 Series Aeroplanes, including models 737-600, -700, -700C, and -800 series with line numbers 1 through 295. This AD mandates an inspection of the rudder pedal housings in accordance with the technical requirements outlined in the Federal Aviation Administration's (FAA) AD 2002-04-08 Amdt 39-12665. The directive is aimed at ensuring the loss of free movement of the rudder pedals is prevented, thereby maintaining the aircraft's controllability. Compliance with the directive is to be conducted as specified in the requirement document, with an effective date of 16 May 2002, and it became effective on the same date. This AD applies to the Commonwealth of Australia and extends to all aircraft operators and maintenance personnel within its jurisdiction, ensuring adherence to safety standards set by the Civil Aviation Safety Authority (CASA) delegate.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, contains a schedule of Airworthiness Directives (ADs) that apply to various aircraft types. Section 39.1 (1) allows a delegate of the Civil Aviation Safety Authority (CASA) to issue an AD when necessary to correct an unsafe condition. In the case of Boeing 737 Series Aeroplanes, AD/B737/177 addresses the rudder pedal housing, effective from 16 May 2002. This AD applies to Model 737-600, -700, -700C, and -800 series aircraft with line numbers 1 through 295. Under this AD, operators of the specified Boeing 737 aircraft models are required to inspect the rudder pedal housing in accordance with the technical requirements of FAA AD 2002-04-08 Amdt 39-12665, with reference to Boeing Service Bulletin 737-25A1383 Revision 1. The inspection is intended to prevent issues such as loss of free movement of the rudder pedals and reduced controllability of the aircraft. The compliance date for this AD is 16 May 2002, as specified in the requirement document, with the AD becoming effective on the same date. The AD imposes specific obligations on the parties or entities it governs. Operators of the Boeing 737 aircraft models mentioned must ensure that the inspection is conducted by appropriately qualified personnel following the specified technical requirements. The inspections must be carried out in a timely manner, adhering to the revised effective date of 16 May 2002. Failure to comply with the AD may result in significant safety risks, potentially leading to serious operational issues. Any breach of this AD may result in civil or criminal consequences. The AD is a legally binding requirement, and non-compliance can lead to enforcement actions by CASA. The specific penalties for non-compliance are not detailed in the AD itself but may include fines, suspension or revocation of aircraft certificates, or other regulatory measures. The maximum penalties would depend on the severity of the breach and the discretion of the relevant authorities.
