AD/HU 369/27 - Emergency Float Assemblies - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, form a critical framework governing the safety and operational standards for civil aviation in Australia. Within this extensive regulatory structure, Part 39 focuses on airworthiness directives that are imperative for ensuring the safety of aircraft. Specifically, Airworthiness Directive (AD) HU 369/27 addresses the modification of emergency float assemblies in McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters. This directive was introduced to address the need for specific modifications to enhance the safety of these helicopters in emergency situations, particularly when water landings are necessary. The directive was enacted by the Civil Aviation Safety Authority (CASA) with a clear policy objective of mitigating risks associated with the emergency float assemblies to ensure the safety of passengers and crew. Compliance with this directive is mandatory for all relevant aircraft, as specified, to ensure consistency with international safety standards and practices.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives. This regulation applies to all models of McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters that are equipped with Hughes emergency float assemblies P/N 369H92036-1 and -2, ensuring compliance with the modifications specified in either Hughes SIN HN-114 or FAA AD 77-09-01 amendment 39-2882. These directives mandate that compliance with the emergency float assemblies must be achieved before 1 August 1977. The geographic and jurisdictional reach of these regulations is national, extending across the Commonwealth of Australia, thereby applying to all relevant helicopters operating within Australian airspace. The regulation does not specify exclusions, exemptions, or thresholds within the text provided, and it is understood that further details may be clarified through subordinate instruments issued under the authority of the Civil Aviation Act 1988.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, address the applicability and compliance of the Airworthiness Directive (AD) concerning the McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters. Section 39.105(1) establishes that the directive applies to all models of these helicopters that are equipped with Hughes emergency float assemblies with part numbers 369H92036-1 and -2. The directive references two key documents: Hughes Service Information Notice (SIN) HN-114 or the Federal Aviation Administration (FAA) AD 77-09-01 amendment 39-2882. Compliance with this directive is mandated to be achieved before 1 August 1977, as outlined in section 39.105(2). The obligations and requirements imposed by this Act on the parties or entities it governs include ensuring that all specified models of the McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters are equipped with the required modifications to their emergency float assemblies. This involves adhering to the specifications and instructions detailed in the Hughes SIN HN-114 or the FAA AD 77-09-01 amendment 39-2882. Operators and owners of these helicopters must ensure that any necessary modifications are completed before the specified compliance date of 1 August 1977. This requirement is critical to maintaining the airworthiness and safety standards of the aircraft as stipulated by the Civil Aviation Safety Authority (CASA). Failure to comply with the provisions outlined in this directive can result in significant civil and potentially criminal consequences. According to section 39.105(3), non-compliance with the AD may lead to penalties under the Civil Aviation Act 1988. These penalties can include fines and, in severe cases, criminal charges. The maximum penalties for breaches of such safety directives can be substantial, reflecting the critical nature of ensuring aircraft safety and airworthiness. It is essential for all parties involved to strictly adhere to the mandated compliance dates and specifications to avoid these severe repercussions.
