AD/F28/29 - Horizontal Stabilizer Assemblies - Modification

Overview

The Civil Aviation Regulations 1998 were enacted to ensure the safety and efficiency of civil aviation in Australia. One of the legislative instruments under these regulations, F2006B09766, addresses specific modifications to Fokker F28 Series Aeroplanes, particularly focusing on the horizontal stabilizer assemblies. This legislative instrument was introduced to ensure compliance with safety directives, as outlined in the Australian Civil Aviation Safety Authority's schedule of airworthiness directives. The policy objective is to maintain the highest standards of aviation safety by mandating specific modifications to certain Fokker F28 models, thereby mitigating potential risks and ensuring the airworthiness of these aircraft. The instrument was enacted by the Australian Government and applies to Fokker F28 aeroplanes with specific serial numbers, requiring compliance by 1 May 1976.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandates modifications to the horizontal stabilizer assemblies of Fokker F28 Series aeroplanes. This legislation applies to all models with serial numbers ranging from 11003 to 11020, 11022 to 11025, and 11991 to 11993, requiring compliance prior to 1 May 1976. The regulation extends across the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority, ensuring that all entities and persons involved in the operation and maintenance of these specific Fokker F28 aircraft adhere to the stipulated modifications. The Act does not explicitly state exclusions or exemptions, but compliance is mandatory for the specified aircraft to maintain their airworthiness and operational certification. Any further elaboration or specification of requirements may be detailed in subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The main operative sections of this Civil Aviation Regulation, specifically AD/F28/29, pertain to the horizontal stabilizer assemblies of Fokker F28 Series aeroplanes. This directive applies to all models with specific serial numbers (11003 to 11020, 11022 to 11025, and 11991 to 11993). Compliance with the directive is required before 1 May 1976. The directive mandates modifications to the horizontal stabilizer assemblies to ensure continued airworthiness and safety of the aircraft, as outlined in document Fokker SB F28/55-17 or RLD AD A108/75. The Civil Aviation Safety Authority (CASA) imposes several obligations on the parties governed by this legislation. Operators of Fokker F28 Series aeroplanes within the specified serial number range must ensure that the horizontal stabilizer assemblies are modified according to the detailed instructions provided in either Fokker SB F28/55-17 or RLD AD A108/75. This involves ensuring that the modifications are carried out by appropriately qualified personnel and documented accordingly. Additionally, operators are required to verify that these modifications are completed before the specified compliance date of 1 May 1976 to maintain compliance with the regulations. Failure to comply with the provisions of AD/F28/29 may result in significant consequences. CASA can impose penalties for non-compliance, which may include fines or other civil penalties as stipulated under the Civil Aviation Act 1988. In severe cases, non-compliance may lead to the grounding of the aircraft until the required modifications are completed, thereby preventing the aircraft from being operated until it meets the safety standards set by the legislation. Operators must therefore ensure strict adherence to the directives to avoid these repercussions.
