Certain Airbus Helicopters H175 helicopters and Leonardo Helicopters AW139/169/189 helicopters operating under a SPA.HOFO Specific Approval are required to be fitted with HTAWS with enhanced capabilities from 1 January 2025. Helicopter Operators and the OEMs, Airbus Helicopters and Leonardo Helicopters, have indicated that the work to upgrade HTAWS cannot be completed in time to meet that implementation date.
Airbus Helicopters have proposed an alternative solution in their Technical Note ref. TN M001A0509E99 Issue A dated 30 September 2024. Leonardo Helicopters have proposed an alternative solution in their document No. MULP3440X001 Issue A dated 02 October 2024. Neither of these are considered to provide an equivalent level of safety to the requirement but may represent potential interim mitigations pending achievement of full compliance.
This exemption is granted to meet urgent operational needs to permit continued operation until 30 June 2025 while any mitigating provisions are agreed and implemented, and while programmes for achieving full compliance are produced and agreed with the respective OEMs.
