AD/S-76/28 - Utility Hoist - Inspection

Overview

The Civil Aviation Regulations 1998, as part of the broader legislative framework overseen by the Civil Aviation Safety Authority (CASA), introduced a specific regulation to address the safety concerns associated with the utility hoist of Sikorsky S-76 series helicopters. This regulation was enacted to mitigate risks associated with the partial separation of the end flange from the drum, which could potentially cause damage to the utility hoist cables. The policy objective behind this regulation is to ensure that the airworthiness of the aircraft is maintained, thereby protecting the safety of all persons on board and on the ground. Compliance with this regulation involves conducting a one-time inspection of the utility hoist before its next operation after 29th March 1983, as per the manufacturer's advisory detailed in Sikorsky Alert Service Bulletin 76-25-5. The enactment of this regulation by the Australian government, through the Civil Aviation Safety Authority, highlights the commitment to addressing specific safety issues identified in aircraft maintenance. The regulation is designed to ensure that any potential risks identified by the manufacturer are promptly addressed, thus preventing accidents and ensuring the continued safety of aviation operations. By mandating a thorough inspection of the utility hoist, the regulation aims to maintain the integrity of this critical component, thereby contributing to overall aviation safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all operators of Sikorsky S-76 series helicopters that are fitted with a utility hoist model number 76076-08002-102 (WE 5431). This regulation is issued under the authority of the Commonwealth of Australia and is applicable nationwide, ensuring that the safety standards are uniformly enforced across all states and territories. The directive mandates a one-time inspection of the utility hoist before the next operation following 29th March 1983, as per the manufacturer's alert service bulletin 76-25-5 (143), which highlights the risk of cable damage due to partial separation of the end flange from the drum. The regulation does not specify any exclusions, exemptions, or thresholds, indicating that all affected helicopters must comply with the inspection requirement to ensure airworthiness.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, address the requirements for Sikorsky S-76 series helicopters with a particular utility hoist model. Section AD/S-76/28 (5/83) mandates a one-time inspection of the utility hoist, which must be completed before the next operation of the hoist after 29th March 1983. This directive applies to S76 series helicopters that are fitted with a 76076-08002-102 (WE 5431) utility hoist, as outlined in the Sikorsky Alert Service Bulletin 76-25-5 (143). The inspection is crucial due to reported incidents of damage to the utility hoist cables, caused by the partial separation of the end flange from the drum. Under this legislation, the primary obligation is for the operators of S76 series helicopters to ensure that the specified utility hoist is inspected in accordance with the directive. Operators must adhere to the timeline set forth, which requires the inspection to occur before the next operation of the utility hoist after the specified date, 29th March 1983. This obligation is intended to maintain the safety and airworthiness of the aircraft by preventing potential hazards associated with the reported cable damage. Failure to comply with the requirements outlined in the Civil Aviation Regulations 1998 can result in serious consequences. Although specific penalties are not detailed in the provided excerpt, non-compliance with airworthiness directives is generally taken very seriously under Australian aviation law. Potential outcomes may include fines, penalties, and other legal actions that could affect the operator's ability to fly the aircraft until the required inspections are satisfactorily completed. The severity of the penalties may vary depending on the specific circumstances of the non-compliance and the discretion of the relevant authorities.
