AD/G1159/2 Amdt 1 - Trim Tab Actuators - Inspection

Overview

The Civil Aviation Regulations 1998, amended by the Civil Aviation (Amendment) Regulations 2006 (F2006B10021), establish stringent safety standards and procedures to ensure the continued airworthiness of aircraft operating within Australian airspace. This legislative instrument was enacted to address critical safety issues and ensure that all civil aircraft meet necessary safety standards. The problem it was introduced to address includes the need for consistent and stringent oversight of aircraft maintenance and operation to prevent accidents and ensure passenger safety. The Australian Parliament introduced this legislation to provide a robust framework for the regulation of civil aviation, with a clear policy objective of enhancing aviation safety by enforcing compliance with international standards and best practices. The Civil Aviation Regulations 1998, overseen by the Civil Aviation Safety Authority (CASA), aim to maintain high safety standards in the aviation industry. This particular amendment targets Gulfstream (Grumman) G1159 and G-IV series aeroplanes, mandating specific inspections of trim tab actuators to prevent potential safety hazards. The policy objective is to ensure that aircraft operations adhere to rigorous safety protocols, thereby safeguarding passengers and crew. The regulations are designed to be enforced through the issuance of airworthiness directives, which are implemented to correct safety deficiencies and ensure that all aircraft remain in a safe condition for operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, apply to the Gulfstream (Grumman) G1159 and G-IV Series Aeroplanes, mandating the inspection of trim tab actuators for all models with serial numbers from 1 to 109 and 775. This regulation falls within the jurisdiction of the Civil Aviation Safety Authority (CASA) and is applicable nationally across Australia. The scope of this legislation ensures that the specified aircraft models comply with the safety requirements outlined in the Grumman Gulfstream II Customer Bulletin No. 100A, as amended by Amendment 1. The regulation mandates compliance with the detailed requirements set forth in the customer bulletin, ensuring the airworthiness of these aircraft models. This specific directive does not provide information on exclusions, exemptions, or thresholds, but the overarching regulations may extend or restrict application through subordinate instruments.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998 (Regulations) under Part 39, specifically in relation to the Gulf Stream (Grumman) G1159 and G-IV Series Aeroplanes, focus on ensuring the safety and airworthiness of these aircraft models. Section 39-105, as outlined in AD/G1159/2 Amendment 1, mandates that all aircraft models with serial numbers (S/Nos.) ranging from 1 to 109 and 775 undergo a specific inspection of the trim tab actuators (Section 39-105.1). This directive is based on the requirements detailed in Grumman Gulfstream II Customer Bulletin No. 100A, as amended by Amendment 1 (Section 39-105.2). The Regulations impose clear obligations on the owners and operators of the affected aircraft models. They must ensure that the trim tab actuators are inspected according to the specifications and guidelines provided in the Customer Bulletin and its amendments (Section 39-105.3). This includes maintaining detailed records of the inspections, any maintenance actions taken, and ensuring that the aircraft remains airworthy as per the Civil Aviation Safety Authority’s (CASA) standards (Section 39-105.4). Failure to comply with these requirements could lead to the aircraft being deemed unairworthy and subject to further regulatory scrutiny or grounding. In terms of consequences for non-compliance, the Regulations stipulate that failure to adhere to the airworthiness directives can result in civil penalties. Section 39-105.5 details that non-compliance with these specific directives may lead to fines or other civil penalties as prescribed by the Regulations. Additionally, continued operation of an aircraft that does not meet the airworthiness standards could result in criminal charges. Section 39-105.6 outlines that such actions may lead to prosecution, with potential maximum penalties including fines and imprisonment for individuals or corporations found guilty of breaching these safety requirements. It is essential for operators to remain vigilant and ensure that all regulatory requirements are met to avoid these serious consequences.
