Overview

The Airworthiness Directive (AD) issued under the Civil Aviation Safety Regulations 1998 (CASR 1998) by the Civil Aviation Safety Authority (CASA) in 2004 aims to address the unsafe condition of damaged basket suspension wires in hot air balloons fitted with solid floor baskets. This legislation was introduced to mitigate the risk of accidents due to the failure of suspension wires, which could lead to tipping and injury to the occupants. The directive mandates that specific actions be taken by the manufacturers and operators of affected balloons to ensure the safety of these aircraft. It requires the revision of the Aircraft Flight Manual to include pre-flight checks for damage to the basket suspension wires and rawhide protectors, and mandates inspections and repairs as necessary, ensuring compliance within a specified timeframe.

Scope and Application

The Airworthiness Directive issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998 applies to all solid floor balloon baskets manufactured by specific companies, including Cameron Balloons Limited, Thunder Balloons Ltd, Colt Balloons Ltd, Thunder and Colt Ltd, and Sky Balloons Ltd. This directive pertains to the maintenance and operational safety of hot air balloons and mandates specific actions to mitigate identified risks. The requirements include revising the Aircraft Flight Manual (AFM) to incorporate detailed pre-flight check procedures for basket suspension wires and ensuring any damage is inspected and repaired as per the manufacturer’s approved data. The directive is applicable nationally within the Commonwealth of Australia, with compliance deadlines set within 7 days and 1 month after the directive's effective date of 1 December 2004. The directive does not specify exclusions or exemptions but outlines the necessity for adherence to the detailed instructions provided.

Key Provisions

This Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of the Civil Aviation Safety Regulations (CASR) 1998, applies to all solid floor balloon baskets manufactured by specific companies (Section 1). The AD mandates that the Aircraft Flight Manual (AFM) for any balloon fitted with a Cameron solid floor basket be revised to include additional information regarding the pre-flight check of basket suspension wires (Section 1(1)). This revision requires that the manual incorporate specific instructions about inspecting the rawhide wire protectors for damage and checking the suspension wires for damage, as outlined in the AD (Section 1(1)). The suspension wires and rawhide protectors must be inspected in accordance with Cameron Balloons Service Bulletin No. 12 Revision 0, or a later approved revision (Section 1(2)). If any damage exceeding permitted levels is found, it must be repaired in line with the manufacturer’s approved data before any further flight (Section 1(2)). Compliance with these requirements must be achieved within specific timeframes: the AFM revision must be completed within 7 days of 1 December 2004, and the inspection and repair of any damaged wires must be completed within 1 month of 1 December 2004 (Section 2). The AD imposes several obligations on the parties it governs. Firstly, the manufacturers and owners of the specified solid floor balloon baskets must revise the AFM of any affected balloon to include the additional flight manual information regarding the inspection and repair of the basket suspension wires and rawhide protectors (Section 1(1)). Secondly, qualified inspectors must inspect the basket suspension wires and rawhide protectors in accordance with Cameron Balloons Service Bulletin No. 12 Revision 0 or later approved revisions (Section 1(2)). If any damage is identified that exceeds permitted levels, it must be repaired in accordance with the manufacturer’s approved data before any further flight (Section 1(2)). The AD requires adherence to these procedures to ensure the safety of the aircraft and its occupants by preventing potential failures of the suspension wires that could lead to tipping and injury. Failure to comply with this AD can result in serious consequences. Although the specific penalties are not detailed in the AD itself, non-compliance with an AD under the Civil Aviation Safety Regulations 1998 can lead to enforcement actions by CASA. These actions may include administrative penalties, fines, or more severe consequences such as grounding of the aircraft until compliance is achieved. The exact penalties can vary based on the nature and severity of the non-compliance, but they are designed to ensure that all relevant parties adhere to the safety requirements set forth in the AD to maintain the airworthiness of the affected aircraft.
