AD/R22/32 - Carburettor Air Box Latches

Overview

The Civil Aviation Regulations 1998, amended through legislative instrument F2006B06437, introduced a specific Airworthiness Directive (AD) concerning the Robinson R22 series helicopters. This directive was enacted to address safety concerns associated with the potential opening of the air box cover during flight, which could lead to critical engine issues. The directive was issued by the Civil Aviation Safety Authority (CASA) to ensure the continued airworthiness of these aircraft by mandating corrective action as specified by the manufacturer, Robinson, through Service Bulletin No 61. Compliance with this directive is required at the next inspection for a Maintenance Release following 31 August 1990 or by 31 December 1990, whichever is earlier, to mitigate the identified risk and enhance flight safety. The objective of this regulatory action was to proactively manage and eliminate potential hazards identified through manufacturer reports, ensuring that all R22 series helicopters meet the necessary safety standards before further operation. By implementing this directive, CASA aims to maintain high safety levels within the aviation sector, particularly for aircraft operations involving the Robinson R22 series helicopters.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Robinson R22 series helicopters, imposing a mandatory requirement concerning the airworthiness of the helicopter's carburetor air box latches. This legislation is intended to ensure the safety of these aircraft by mandating compliance with Robinson Service Bulletin No. 61, which addresses the issue of the air box cover opening during flight. The regulation is applicable to all R22 series helicopters and requires that corrective action be taken unless it has already been performed. Compliance with this directive must be achieved at the next inspection, either for the issue of a Maintenance Release after 31 August 1990 or by 31 December 1990, whichever comes first. The regulation applies nationally and is enforced by the Civil Aviation Safety Authority, ensuring a uniform standard of safety across all jurisdictions within Australia. There are no stated exclusions or exemptions in this directive, and its scope is limited to the specified series of helicopters and the particular safety concern of the air box cover.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an airworthiness directive (AD) for the Robinson R22 Series Helicopters, identified as AD/R22/32, which pertains to the carburetor air box latches (section 8/90). This directive applies to all R22 series helicopters and requires compliance unless the specified action has already been performed. The requirement is that the action must be taken in accordance with Robinson Service Bulletin No 61, which details the corrective measures needed to address an issue with the air box cover opening in flight. Compliance with this directive must occur at the next inspection for the issue of a Maintenance Release after 31 August 1990 or by 31 December 1990, whichever is earlier. The obligations imposed by this directive are clear and specific. Operators of R22 series helicopters must ensure that the corrective action as outlined in Robinson Service Bulletin No 61 is implemented. This involves the inspection and, if necessary, the repair or replacement of the carburetor air box latches to prevent the air box cover from opening in flight. The directive binds operators to maintain the airworthiness of their helicopters by adhering to the manufacturer's instructions, which have been issued in response to reported incidents of the air box cover opening during flight. Failure to comply with this airworthiness directive may lead to serious safety implications, as the directive is designed to address a known safety hazard. Under the Civil Aviation Act 1988, non-compliance can result in civil or criminal penalties. The specific consequences and penalties are determined by the Civil Aviation Regulations and may include fines or imprisonment, depending on the severity and intent of the breach. The exact penalties are not specified in the directive itself but are outlined in the broader regulatory framework that governs civil aviation safety in Australia.
