AD/MSR/28 Amdt 1 - Horizontal Stabilizer Spar and Attachment Fittings

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, introduces Airworthiness Directives to ensure the safety and reliability of aircraft operations within Australia. This legislative instrument, F2006B11327, addresses the identified problem of cracking in the forward attachment fittings and spar of Aerospatiale Rallye Series Aeroplanes. Enacted by the Australian Commonwealth Government, this directive aims to enhance aviation safety by implementing specific maintenance requirements. The policy objective is to ensure that all relevant aircraft models comply with the mandated inspections to prevent structural failure, thereby safeguarding the safety of passengers and crew. Compliance with these directives is mandatory and must be adhered to within specified time frames following the enactment date of 30 April 1986. This legislative instrument underscores the importance of regular and stringent maintenance checks in the aviation industry, aiming to preempt and mitigate potential safety hazards. The directive references Revision 1 of Rallye Service Bulletin No. 145, reinforcing the necessity for repetitive inspections and timely actions to address the reported issues. By mandating these measures, the Civil Aviation Regulations 1998 contribute to the overarching goal of maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, under PART 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically addresses the maintenance and inspection requirements for Aerospatiale Rallye series aeroplanes. This legislation applies to a comprehensive list of models including MS 880 B, MS 880 B-D, MS 885, MS 881, MS 883, 100 ST-D, 150 ST, 150 ST-D, 150 T, 150 T-D, 180 T, 180 TS, 180 T-D, 150 SV, 150 SVS, 110 ST, MS890 A, MS 890 B, MS 892 A 150, MS 892 B 150, MS 892 E 150, MS 892 E-D 150, MS 893 A, MS 893 B, MS 893 E, MS 893 E-D, MS 894 A, MS 894 C, MS 894 E, Rallye 235 E, 235 E-D, 235 A, R 235 F, 235 C. These directives are applicable to any person or entity operating these specific aeroplane models in Australia, ensuring compliance with the stipulated airworthiness requirements to maintain the safety and integrity of these aircraft. The requirement mandates action in accordance with Rallye SB No. 145, Revision 1, and necessitates compliance within 100 hours of time in service after 30 April 1986 or at the next scheduled inspection for Maintenance Release issue after 30 April 1986, whichever is later, and subsequently at each scheduled inspection. The directive responds to reported cracking of the forward attachment fittings and spar, emphasizing the importance of regular inspections and maintenance to prevent further damage and ensure safe operation.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, sets forth the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives (AD) that govern the maintenance and inspection requirements for various aircraft models. In this case, AD/MSR/28 Amendment 1 pertains to Aerospatiale Rallye Series Aeroplanes, mandating specific actions related to the horizontal stabilizer spar and attachment fittings (section 5/87). This directive applies to numerous Aerospatiale Rallye models including MS 880 B, MS 880 B-D, MS 885, and others as listed. The directive requires compliance with Rallye Service Bulletin No. 145/1. Owners and operators of the specified Aerospatiale Rallye Series Aeroplanes must ensure that the action outlined in this service bulletin is carried out within 100 hours of time in service after 30 April 1986, or at the next scheduled inspection for maintenance release issue after 30 April 1986, whichever comes later. Following this initial compliance, the inspections must be repeated at each scheduled maintenance release inspection. Failure to adhere to the requirements stipulated in this airworthiness directive can result in significant consequences. CASA has the authority to take enforcement actions against non-compliance, which may include fines, suspension, or revocation of the aircraft's certificate of airworthiness. Such enforcement actions are designed to ensure the safety of air travel by maintaining the integrity of the aircraft in accordance with regulatory standards. The specific penalties for non-compliance are determined by CASA and can vary based on the severity and circumstances of the breach.
