EASA SIB NE-11-27: General Electric CF6-80 Engines - Improperly Welded Fuel Nozzles

What to do

Operators and maintenance facilities should check if fuel nozzles with part numbers 6980200E03 through 6980200E16 or 1968M49P03 through 1968M49P16 and serial numbers listed in Table 1 of SAIB NE-11-27 are installed on their aircraft. If affected nozzles are found, they should follow the corrective actions outlined in Parker Hannifin Corporation Service Bulletin 6980200-73-001 SB_R0 dated January 17, 2011. No specific compliance deadline is stated, but prompt action is recommended.

Summary

The FAA Special Airworthiness Information Bulletin SAIB: NE-11-27 addresses improperly welded fuel nozzles in General Electric CF6-80A, CF6-80C2, and CF6-80E1 series turbofan engines. These engines are installed on aircraft including Airbus A300, A310, A330, Boeing 747, 767, and McDonnell Douglas MD-11 series airplanes. The bulletin informs operators and maintenance personnel about the discovery of incomplete welds on specific fuel injector nozzles, which could lead to fuel leaks and potential engine shutdowns.

What changed

This SAIB introduces awareness of a maintenance issue involving improperly welded fuel nozzles with certain part and serial numbers on CF6-80 series engines. It does not mandate regulatory action but recommends inspection and corrective measures based on Parker Hannifin Service Bulletin 6980200-73-001 SB_R0. The bulletin provides a list of affected nozzle serial numbers for identification.

Why it matters

The issue is critical for aviation professionals because incomplete welds in fuel nozzles can cause fuel leaks and uncommanded engine shutdowns, impacting flight safety and operational reliability. Operators and maintenance organizations need to identify affected parts to prevent in-flight engine failures and ensure continued airworthiness. Early detection and repair reduce the risk of unscheduled maintenance and potential safety incidents.
