EASA AD G-2022-0021
Time Limits / Maintenance Checks — Corrosion Prevention and Control Programme — Amendment / Implementation
Summary
Civil Aviation Authority Airworthiness Directive G-2022-0021 addresses corrosion prevention and control for BAE Systems Jetstream 3100 and 3200 aeroplanes. It mandates compliance with the updated Corrosion Prevention and Control Programme (CPCP) document Revision 9 to ensure continued airworthiness. This directive applies to all models and serial numbers of the Jetstream 3100 and 3200 series.
What Changed
This directive supersedes EASA AD 2017-0073 and introduces new and more restrictive inspection tasks targeting corrosion in specific areas such as the Rudder Tab Hinges and fuselage skin beneath certain antenna external doublers. The CPCP document has been updated to Revision 9, which includes revised descriptions and inspection intervals for corrosion-prone areas.
Why It Matters
For aviation professionals, this directive ensures enhanced detection and prevention of corrosion-related issues that could compromise aircraft safety. Operators and maintenance organizations must update their maintenance programs to incorporate these stricter inspection requirements, reducing the risk of undetected corrosion and potential structural failures. Compliance with this AD is mandatory to maintain the continuing airworthiness of affected aircraft.
What To Do
Operators must accomplish all applicable CPCP maintenance tasks as specified in Revision 9 from the effective date, including new tasks within 12 months and at intervals thereafter. They must revise the approved Aircraft Maintenance Programme within 12 months to include all relevant tasks and intervals. If corrosion discrepancies are found during inspections, operators must contact BAE Systems for approved corrective actions before further flight.
