AD/DHC-3/28 - Front Fuselage - Windshield Post

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, are designed to ensure the safety of civil aviation. Specifically, Part 39 - 105 pertains to the Civil Aviation Safety Authority’s schedule of airworthiness directives, which includes the regulation of DHC-3 (Otter) series aeroplanes. This legislation addresses the need for ongoing maintenance and compliance to ensure that aircraft meet safety standards. The policy objective is to mandate specific actions for the maintenance and safety of the front fuselage windshield post, ensuring that all models adhere to the standards set out in De H Canada SB No 3/29. Compliance with these directives is required within 100 hours of time in service after 30 June 1977, thereby reinforcing the commitment to maintaining the highest standards of aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all models of DHC-3 (Otter) series aeroplanes. This regulatory directive mandates that all operators of such aircraft must comply with De H Canada SB No 3/29 concerning the front fuselage windshield post. Compliance with this directive is required within 100 hours of time in service after 30 June 1977, ensuring that the safety and airworthiness standards are maintained across the aviation industry. The scope of this regulation encompasses all DHC-3 series aeroplanes within the Commonwealth of Australia, imposing a mandatory safety requirement that must be met by all operators of these aircraft. The regulation does not specify exclusions or exemptions, thus applying uniformly to all relevant entities and aircraft within the designated timeframe.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically address airworthiness directives for various aircraft, including the DHC-3 (Otter) Series Aeroplanes. One such directive is AD/DHC-3/28, which pertains to the front fuselage and the windshield post. This directive applies to all models of the DHC-3 series, as indicated by the applicability clause. It requires compliance in accordance with the De H Canada Service Bulletin No 3/29. The key requirement here is that the specified action must be taken within 100 hours of time in service after the directive's effective date of 30 June 1977. The obligations imposed by this directive are clear: operators and owners of DHC-3 series aircraft must ensure that the front fuselage and windshield post are addressed as per the prescribed service bulletin. This involves conducting the necessary actions and maintaining records of compliance to demonstrate adherence to the directive. Ensuring timely and accurate implementation of these requirements is crucial for maintaining the airworthiness of the aircraft. Failure to comply with the provisions outlined in AD/DHC-3/28 can result in serious consequences. The Civil Aviation Safety Authority (CASA) enforces these regulations, and non-compliance may lead to enforcement actions. These can include fines, penalties, and potentially grounding of the aircraft until the required actions are completed. The specific penalties and enforcement measures are detailed in the broader Civil Aviation Regulations, but they are designed to ensure the safety and airworthiness of the aircraft are not compromised.
