What to do
Operators of BAe ATP aeroplanes must modify their aircraft by installing moisture covers on the FDR, DARU, and FDAU within six months from 8 June 2023, following Service Bulletin ATP-31-028. For aircraft not yet modified, an FDR/DARU data download and readout must be performed within six months of the last data download performed under AD G-2022-0012, in accordance with Service Bulletin ATP-31-027 or the Maintenance Planning Document. Compliance with these actions is mandatory to continue operation.
Summary
The Civil Aviation Authority Airworthiness Directive G-2023-0003 addresses the flight data recording system on BAe ATP aeroplanes. It mandates modifications to protect the Flight Data Recorder (FDR), Data Acquisition and Recording Unit (DARU), and Flight Data Acquisition Unit (FDAU) from moisture ingress, which has been linked to intermittent recording faults. This directive applies to all manufacturer serial numbers of BAe ATP aircraft.
What changed
This directive supersedes the previous AD G-2022-0012 and introduces a modification requiring the installation of moisture covers on the FDR, DARU, and FDAU to prevent moisture ingress. It removes the previously increased frequency requirement for FDR/DARU data downloads, reinstating the original maintenance intervals as per the ATP Maintenance Planning Document. The modification is detailed in BAE Systems Service Bulletin ATP-31-028.
Why it matters
This AD is critical for aviation professionals as it addresses a safety concern involving moisture ingress that can cause flight data recording failures, potentially impacting accident investigations and flight safety. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid operational restrictions. The modification improves reliability of flight data systems, reducing the risk of data loss during flight incidents.
