AD/DHA-3/7 - Horizontal Tail Plane Attachments - Modification

Overview

The Civil Aviation Regulations 1998, as amended by F2006B08990, were enacted to address safety concerns and ensure the maintenance of airworthiness standards for civil aircraft within Australia. This legislative instrument is part of a broader framework designed to enhance the safety of civil aviation by imposing stringent regulatory requirements and modifications on aircraft operations. The policy objective behind these regulations is to mitigate risks associated with aviation safety through the enforcement of airworthiness directives, ensuring that all aircraft meet necessary safety standards. These regulations are administered by the Civil Aviation Safety Authority, a body established under the Civil Aviation Act 1988, tasked with the responsibility of overseeing compliance with aviation safety standards and directives.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandates that all Drover Series Aeroplanes, irrespective of model, must comply with the modifications outlined in the Airworthiness Directive DHA-3/7. This directive pertains to the horizontal tail plane attachments and requires immediate compliance. The regulation references documents such as DH Mod. DRO 80, DH TNS CT(A3) No. 86, and ANO 105.1.14.14.5.8 as the basis for the required modifications. The applicability extends across the Commonwealth of Australia, ensuring a uniform standard for airworthiness across all states and territories. The Act applies directly to aeroplanes of the Drover series, with no exclusions or exemptions explicitly stated within the provided text. Any further specification or exceptions may be detailed in subordinate instruments linked to the Civil Aviation Regulations 1998.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, mandates certain safety directives for aircraft operated under Australian jurisdiction. The section in focus here is AD/DHA-3/7, which pertains to the horizontal tail plane attachments for Drover series aeroplanes. This Airworthiness Directive (AD) requires a modification to the horizontal tail plane attachments for all models within the Drover series (section 9/54). Compliance with this directive is mandatory and must be carried out forthwith, as stipulated in the document, which can be found in DH Mod. DRO 80, DH TNS CT(A3) No. 86, or ANO 105.1.14.14.5.8. Entities and individuals governed by these regulations must ensure that the specified modifications to the horizontal tail plane attachments are performed without delay. The requirement is clear and unambiguous, with an expectation that compliance is immediate. This obligation extends to all parties involved in the maintenance, operation, or certification of the Drover series aeroplanes. The onus is on these parties to verify that the modifications are correctly implemented and that the aircraft remain in compliance with the safety standards set forth by the Civil Aviation Safety Authority (CASA). Failure to comply with the provisions outlined in AD/DHA-3/7 may result in serious consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance, which can include substantial fines and potential criminal charges. The exact penalties are not specified in the text, but it is well-established within the regulatory framework that severe infractions can lead to significant repercussions. The overarching aim is to ensure that all measures are taken to maintain the highest safety standards in civil aviation, thereby protecting both the public and the integrity of the aviation industry.
