AD/S-PUMA/32 - Connectral Electrical Connection Modules

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, address safety issues in civil aviation, particularly through the Civil Aviation Safety Authority (CASA) which oversees airworthiness directives. One such directive is AD/S-PUMA/32, issued to address a specific manufacturing defect identified in Eurocopter AS 332 (Super Puma) Series Helicopters. This defect, concerning electrical discontinuity in connection modules manufactured by Connectral between 17 April 1995 and 1 August 1996, was found to affect the helicopters' safety. The directive mandates functional checks on electrical circuits under vibration conditions and for spare modules, ensuring compliance within 200 flying hours from its effective date of 10 September 1998, or by 31 December 1998 at the latest. The policy objective is to maintain and enhance the safety standards of civil aviation operations by mitigating risks associated with identified manufacturing defects.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to Eurocopter AS 332 (Super Puma) Series Helicopters. The directive pertains to AS 332C, C1, L and L1 helicopters equipped with electrical connection modules manufactured by Connectral S.A. Suresnes, France. This applies if the helicopters were manufactured between 17 April 1995 and 1 August 1996, if an optional electrical circuit equipped with a Connectral module has been installed or replaced during this period, or if an electrical circuit has been modified with the installation or replacement of a module within the same timeframe. The directive mandates specific checks on the functions of the electrical circuits of various systems under vibration conditions and requires the inspection of Connectral modules held as spares. Compliance with this directive must be achieved within 200 flying hours from the effective date of 10 September 1998, but no later than 31 December 1998, and must be completed prior to the installation of any modules on a helicopter after the directive becomes effective.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, includes a directive for the Eurocopter AS 332 (Super Puma) Series Helicopters, referred to as AD/S-PUMA/32. This directive (section 10/98DM) applies to AS 332C, C1, L and L1 helicopters equipped with electrical connection modules manufactured by Connectral S.A. Suresnes, France between 17 April 1995 and 1 August 1996. The directive mandates that the functions of the electrical circuits of these helicopters must be checked under vibration conditions (with the rotor spinning) in accordance with Paragraph 2 of Eurocopter AS 332 Mandatory Service Bulletin No 01.00.51 date code 98-22. Additionally, Connectral modules held as spares must also be checked in accordance with Paragraph 2.A.b. of the same service bulletin. The obligations imposed by this directive require operators of the specified Eurocopter AS 332 helicopters to conduct these checks. The directive mandates that these checks must be completed within 200 flying hours from the effective date of the directive, which is 10 September 1998, and no later than 31 December 1998. Moreover, any Connectral modules intended for installation on a helicopter after the directive's effective date must be checked prior to installation. This directive is issued due to a manufacturing defect identified by Eurocopter, which causes electrical discontinuity. This defect affects only electrical connection modules manufactured by Connectral from week 95/16 to week 96/21. The purpose of this directive is to ensure that these defective electrical connection modules are detected and addressed. Failure to comply with this airworthiness directive can lead to significant consequences. The regulations do not explicitly detail the penalties or consequences for non-compliance within the directive text provided. However, generally, non-compliance with airworthiness directives under the Civil Aviation Regulations can result in severe penalties. These may include fines, suspension or revocation of the operator's certificate, or other regulatory actions deemed necessary by the Civil Aviation Safety Authority. Such penalties reflect the critical nature of ensuring the airworthiness of aircraft and the safety of passengers and crew.
