EASA SIB 2008-86
Airbus A330-A340 - Uncertified Aircraft Configuration
Summary
EASA Safety Information Bulletin No: 2008 – 86 is an informational document addressing uncertified aircraft configurations affecting Airbus A330 and A340 models. It highlights incidents where unauthorized Flight Control Primary Computer (FCPC) configurations caused elevator and spoiler control issues, leading to unsafe aircraft behavior. The bulletin covers all serial numbers of specified Airbus A330 and A340 variants.
What Changed
This bulletin introduces awareness about the risks associated with mixing unauthorized FCPC part numbers in Airbus A330 and A340 aircraft. It documents specific incidents from 2004 and 2008 where improper FCPC configurations led to control anomalies. The bulletin does not mandate changes but provides recommendations to prevent such uncertified configurations.
Why It Matters
Understanding and preventing uncertified FCPC configurations is critical for aviation professionals to avoid unexpected aircraft control behavior that can compromise flight safety. Operators and maintenance organizations must ensure compliance with Airbus Type Certificate Holder documentation to maintain aircraft airworthiness. Regulatory authorities are reminded to verify aircraft configurations to uphold safety standards.
What To Do
Owners and operators of Airbus A330 and A340 aircraft should strictly follow Airbus interchangeability and mixability rules for FCPC components to prevent unauthorized configurations. EU Member States should verify that aircraft registered under their authority comply with Airbus Type Certificate Holder documentation. No mandatory compliance deadline is specified, as the bulletin serves as guidance only.
