AD/JETSTREAM/42 - Hydraulic Power - Emergency Hydraulic Hand Pump

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive legal framework designed to regulate and ensure the safety of civil aviation within the country. One specific piece of legislation within this regulatory body, F2006B10911, addresses the issue of ensuring the airworthiness of British Aerospace BAe 3100 (Jetstream) Series Aeroplanes. This legislative instrument was introduced to address instances where there have been difficulties in accessing the emergency hydraulic hand-pump in the event of hydraulic system failures, potentially compromising the safety of the aircraft and its occupants. The policy objective of this directive is to mandate regular inspections and modifications of the affected aircraft to mitigate such safety risks, thereby enhancing overall aviation safety standards in line with the requirements set out by British Aerospace and the UK Civil Aviation Authority. This particular directive under the Civil Aviation Regulations 1998 applies to Jetstream Series 3100 aircraft with specific construction numbers, demanding that these aircraft be inspected and modified according to British Aerospace Service Bulletin, CAA (UK) Mandatory, 29-JM 7360 Revision 1. The compliance for Australian registered aircraft is stipulated with a revised effectivity date of 18 April 1991, ensuring that all necessary actions are taken to address the identified safety concerns. The legislation aims to maintain high safety standards and prevent incidents related to the accessibility of emergency hydraulic systems, thus contributing to the overall safety and reliability of civil aviation operations in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning Airworthiness Directives, apply to Jetstream Series 3100 aeroplanes with certain construction numbers, specifically from 601 to 646, 648 to 655, 658, and 660. This legislation mandates that these aircraft must be inspected and/or modified in line with the British Aerospace Service Bulletin, CAA (UK) Mandatory, 29-JM 7360 Revision 1, with a modified effectivity date of 18 April 1991 for those registered in Australia. The primary objective of this directive is to address reported issues where access to the emergency hydraulic hand pump has been problematic during hydraulic system failures. The scope of the Act encompasses Australian registered aircraft meeting the specified construction numbers, ensuring compliance with the stipulated modifications to enhance safety and operational reliability. No exclusions or exemptions are explicitly stated within the given text, and the application extends to all relevant aircraft within the prescribed construction number range.

Key Provisions

The main operative sections of the Civil Aviation Safety Authority's (CASA) Airworthiness Directive (AD) JETSTREAM/42 for the British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, as outlined in Part 39 - 105 of the Civil Aviation Regulations 1998, focus on ensuring the safety of hydraulic systems during emergency operations (Regulation 39.105). Specifically, section 4/91 DM requires that Jetstream Series 3100 aircraft with construction numbers ranging from 601 to 646, 648 to 655, 658, and 660 undergo inspection and/or modification of their emergency hydraulic hand pump (AD JETSTREAM/42). This directive mandates compliance with British Aerospace Service Bulletin, CAA (UK) Mandatory, 29-JM 7360 Revision 1, with a specified effectivity date of 18 April 1991 for Australian registered aircraft. The obligations imposed by this legislation require operators of the affected Jetstream aircraft to conduct thorough inspections and necessary modifications of the emergency hydraulic hand pump as per the specified service bulletin. This includes ensuring that all maintenance and modifications are carried out in accordance with the detailed requirements of the service bulletin and that any modifications are implemented by the revised effectivity date of 18 April 1991 for Australian-registered aircraft. Operators must ensure that their maintenance records accurately reflect any actions taken in compliance with this AD to demonstrate adherence to safety standards. Failure to comply with the requirements of AD JETSTREAM/42 can result in serious consequences. The Civil Aviation Regulations 1998 stipulate that non-compliance with an AD is an offence, which can lead to both civil and criminal penalties. In the context of this directive, operators who fail to inspect and/or modify their aircraft in accordance with the specified service bulletin may face enforcement actions from CASA. The penalties for such breaches can include fines and, in severe cases, the potential grounding of the aircraft until compliance is achieved. The exact penalties can vary, but they are designed to ensure the highest safety standards are maintained in civil aviation operations.
