AD/BAL/18 - Trivents

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains Airworthiness Directives intended to maintain the safety standards of aircraft, including hot air balloons. The directive AD/BAL/18 focuses on the Trivents of certain Thunder and Colt balloon envelopes, which were identified to have potential issues with the stitching at the ends of the attachment loop. This directive was enacted by the Civil Aviation Safety Authority to address the need for regular inspection and reinforcement of these balloon envelopes to ensure their structural integrity and compliance with safety standards. The overarching policy objective is to mitigate the risk of failure during flight, thereby enhancing the safety of air travel. Enacted by the Commonwealth of Australia and administered by the Civil Aviation Safety Authority, this regulation was introduced to address a specific safety concern identified in Thunder and Colt balloon envelopes, particularly those listed by serial numbers. The directive mandates that inspections and necessary reinforcements be carried out to prevent damage to the red line attachment on the trivent flap, thereby ensuring these balloons meet the required safety standards before each flight. The directive became effective on 24 April 1997, establishing clear compliance requirements to be met within a specified timeframe to maintain airworthiness.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives for hot air balloons, with AD/BAL/18 addressing Trivents for certain Thunder and Colt balloon envelopes. This regulation applies to the specific serial and construction numbers listed, mandating that the red line attachment on the trivent flap must be inspected for damage to the stitching at the ends of the attachment loop in accordance with Cameron Balloons Ltd (Thunder & Colt) Service Bulletin SB3 Issue 1 revision C. It also requires the reinforcement of these attachments in accordance with the same service bulletin. Compliance with these directives is mandatory unless the specified actions have already been completed, with inspections required before every flight after 24 April 1997, and reinforcement within 20 hours of time in service after the same date. This Airworthiness Directive is effective as of 24 April 1997, ensuring that the specified balloon envelopes meet the necessary safety standards for operation.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 – 105, under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, includes specific provisions concerning the inspection and reinforcement of hot air balloons, particularly those made by Thunder and Colt. This directive (AD/BAL/18) is targeted at Trivent balloon envelopes with specific serial numbers (SN 3528, CN 3553, CN 3688, etc.), requiring these balloons to undergo detailed inspections and necessary repairs before and after certain flight hours. Section 1 of the directive mandates that the red line attachment on the trivent flap must be inspected for any damage to the stitching at the ends of the attachment loop, following the guidelines set out in Cameron Balloons Ltd Service Bulletin SB3 Issue 1 revision C. Furthermore, Section 2 requires that these attachments be reinforced in accordance with the same service bulletin. Compliance with these requirements is critical, with inspections and reinforcements to be completed before any flight after 24 April 1997, and within 20 hours of time in service following that date, until the reinforcement is accomplished. The obligations under this directive are clear and specific. Operators of Thunder and Colt balloon envelopes with the listed serial numbers must ensure that the inspections and reinforcements are performed as directed. This includes adhering strictly to the Cameron Balloons Ltd Service Bulletin SB3 Issue 1 revision C, which provides detailed instructions on how to conduct the inspections and carry out the necessary repairs. Failure to comply with these directives could result in the balloon not being deemed airworthy, thus preventing any flight operations involving the affected balloons. Violating these provisions could lead to significant consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives. While specific penalties are not detailed in this directive, general regulations under the Civil Aviation Act 1988 may apply. These can include substantial fines and potential criminal charges for individuals responsible for ensuring compliance, as well as liabilities for any accidents or incidents resulting from non-compliance. Therefore, operators must take these directives seriously and ensure that all required inspections and reinforcements are performed in a timely and accurate manner to avoid any legal repercussions.
