EASA SIB NE-17-27: Pratt & Whitney Canada PW100 Engines - Wencor Main Engine Fuel Filters

What to do

Owners and operators of Pratt & Whitney Canada PW100 series engines with Wencor PMA fuel filters, part number 5905587WE, should inspect installed and in-stock filters for excess epoxy as described in Wencor Service Bulletin 160330-5905587WE, Rev A or later versions. They should implement any corrective actions recommended by the service bulletin to mitigate potential fuel flow issues. No specific compliance deadline is provided, but timely action is advised.

Summary

The FAA Special Airworthiness Information Bulletin SAIB: NE-17-27 provides information regarding Wencor PMA main engine fuel filters, part number 5905587WE, used on Pratt & Whitney Canada PW100 series engines including models PW118 through PW127. This bulletin alerts operators and maintenance facilities about a quality issue involving excess blue epoxy found on some fuel filters, which could potentially affect fuel flow. The bulletin applies to multi-engine aircraft equipped with these engines but does not mandate corrective action.

What changed

SAIB NE-17-27 introduces an advisory about a quality escape involving excess epoxy on Wencor PMA fuel filters for PW100 series engines. It highlights the potential risk without declaring an unsafe condition that requires an Airworthiness Directive. The bulletin recommends following Wencor Service Bulletin 160330-5905587WE, Rev A, or later revisions for inspection and corrective measures.

Why it matters

This information is important for aviation professionals because it identifies a potential fuel flow risk due to manufacturing defects in engine fuel filters, which could impact engine performance. Operators and maintenance organizations need to be aware of this issue to ensure continued airworthiness and prevent possible fuel system complications. Although not mandatory, following the recommendations helps maintain safety and reliability of affected Pratt & Whitney Canada PW100 engines.
