What to do
Operators should implement systematic checks or establish procedures to verify the correct identification and applicability of part numbers in their spares management systems against approved maintenance data and manufacturer configuration definitions. Regular cross-checks with the Illustrated Parts Catalogue are recommended to prevent incorrect part installations. No specific compliance deadline is stated, but timely action is advised.
Summary
EASA Safety Information Bulletin SIB No: 2010-11 addresses discrepancies between manufacturer aircraft configuration data and operators' spares management systems, specifically involving the ATR 72 aircraft. The bulletin highlights an incident where an incorrect Fuel Quantity Indicator part number for the ATR 42 was fitted on an ATR 72, causing erroneous fuel readings. It emphasizes the importance of using approved maintenance data and manufacturer configuration data for component eligibility.
What changed
This bulletin introduces recommendations for operators to systematically verify part number applicability and interchangeability data between maintenance documentation and spares management databases. It highlights the need for final checks against the Illustrated Parts Catalogue to ensure correct parts are installed. The bulletin does not impose mandatory requirements but supports improved configuration control practices.
Why it matters
Accurate component configuration control is critical to ensure aircraft safety and operational reliability. Discrepancies in part numbers can lead to incorrect parts being installed, potentially causing system malfunctions or safety hazards. Operators, maintenance organizations, and compliance teams must ensure their spares management systems align precisely with manufacturer data to avoid such risks.
