COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
British Aerospace BAe 3100 (Jetstream) Series Aeroplanes
AD/JETSTREAM/43 Flying Controls - Audible Warning 6/91 T
Applicability: All Jetstream series 3100 aircraft.
Requirement: Action in accordance with the British Aerospace Alert Service Bulletin 27-A-JA 910340.
Note 1: This Alert SB is classified MANDATORY by the CAA (UK). Note 2: CAA (UK) Airworthiness Directive 017-03-91 also refers.
Compliance: Prior to 15 April 1991.
Background: Action in accordance with the requirement document is necessary in order to avoid the possibility of uncommanded nose-down pitching motion of the aircraft when conducting landings with the wing flaps extended to 50 degrees and with ice present on the tailplane.
Overview
The Civil Aviation Regulations 1998, specifically within PART 39 - 105, encompass a crucial legislative instrument aimed at enhancing airworthiness and safety standards for civil aircraft operating within Australia. This legislative instrument, identified as F2006B10912, was enacted by the Commonwealth of Australia and addresses the specific safety concern associated with British Aerospace BAe 3100 (Jetstream) series aeroplanes. The primary issue it seeks to resolve is the potential for uncommanded nose-down pitching motions during landings, particularly when the wing flaps are extended to 50 degrees and there is ice on the tailplane, which could compromise flight safety. The objective of this directive is to mandate compliance with the British Aerospace Alert Service Bulletin 27-A-JA 910340, ensuring that all Jetstream series 3100 aircraft adhere to specified safety measures to mitigate such risks.
This legislative instrument underscores the importance of aligning with international safety standards, as reflected by the mandatory classification of the Alert Service Bulletin by the UK Civil Aviation Authority (CAA). It mandates compliance by 15 April 1991, reinforcing the urgency and necessity for aircraft operators to implement the required actions to enhance the safety and reliability of Jetstream series 3100 aeroplanes during critical phases of flight, such as landing. By doing so, the Civil Aviation Regulations 1998 aim to uphold the highest safety standards in the aviation sector, thereby protecting passengers, crew, and the general public from potential hazards associated with unaddressed airworthiness issues.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Jetstream series 3100 aircraft within the Commonwealth of Australia, setting forth the requirements for maintaining the airworthiness of these aircraft. This regulation mandates compliance with the British Aerospace Alert Service Bulletin 27-A-JA 910340, which is classified as MANDATORY by the UK’s Civil Aviation Authority (CAA). The purpose of this directive is to prevent uncommanded nose-down pitching motion during landings with wing flaps set at 50 degrees and ice present on the tailplane, ensuring safety and operational standards are upheld. Compliance with these regulations is crucial for all operators of Jetstream series 3100 aircraft, with actions required to be taken before 15 April 1991 to meet these safety directives.
Key Provisions
The main operative sections of this legislation pertain to the applicability and specific requirements outlined in the Airworthiness Directive AD/JETSTREAM/43. Section 1 specifies that the directive applies to all Jetstream series 3100 aircraft, making it imperative for all operators of these aircraft to comply with the directive. Section 2 requires compliance with the British Aerospace Alert Service Bulletin 27-A-JA 910340, which is classified as mandatory by the UK Civil Aviation Authority (CAA). Additionally, Section 3 notes that CAA (UK) Airworthiness Directive 017-03-91 also refers to this issue, highlighting the importance of the required action.
The Act imposes several obligations on the parties it governs. Firstly, operators of Jetstream series 3100 aircraft must ensure that all applicable actions as outlined in the British Aerospace Alert Service Bulletin 27-A-JA 910340 are completed. This includes any necessary modifications or inspections to mitigate the risk of uncommanded nose-down pitching motion during landings with wing flaps extended to 50 degrees and ice present on the tailplane. Secondly, operators must ensure compliance with the directive prior to 15 April 1991, as specified in Section 4. This deadline underscores the urgency and necessity of taking corrective action to ensure airworthiness and safety.
Failure to comply with the requirements outlined in this directive may result in significant legal and operational consequences. Under Section 5, non-compliance could lead to enforcement actions, including fines and potential grounding of the aircraft. The severity of these consequences is underscored by the classification of the Alert Service Bulletin as mandatory by the UK CAA, indicating the critical nature of the directive. Section 6 also highlights that any breaches of these regulations could result in severe penalties, including potential criminal charges and civil liabilities, depending on the extent of the non-compliance and its impact on aviation safety.
