Fuel Injector Nozzle - CF6-80 Improperly Welded Fuel Nozzles

FAA Aviation Safety SPECIAL AIRWORTHINESS INFORMATION BULLETIN SAIB: NE-11-27 SUBJ: Fuel Injector Nozzle - CF6-80 Improperly Welded Fuel Nozzles Date: April 5, 2011 This is information only. Recommendations aren’t mandatory.

Introduction

This Special Airworthiness Information Bulletin (SAIB) is to advise you, registered owners, operators, and certificated repair facilities of all airplanes equipped with General Electric Company (GE) CF6-80A, CF6-80C2 and CF6-80E1 series turbofan engines of the discovery of improperly repaired fuel nozzles, part numbers (P/Ns) 6980200E03 thru 6980200E16 and corresponding P/Ns 1968M49P03 thru 1968M49P16, with serial numbers (S/Ns) listed in Table 1 of this SAIB.

The affected engines are installed on, but not limited to, Airbus A300, A310, and A330 series airplanes, Boeing 747 and 767 series airplanes, and McDonnell Douglas MD-11 series airplanes.

The airworthiness concern is not an unsafe condition that would warrant airworthiness directive action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.

Background

Following a routine maintenance check, an airplane was found with a fault message that required replacing the fuel filter. The subsequent leak check found a leaking fuel nozzle. Testing confirmed that the leak was due to an incomplete weld of the nozzle. Additional fuel nozzles repaired using the same procedure were evaluated and a number of nozzles were identified as having an incomplete weld.

If not corrected, the incomplete weld in these fuel nozzles may lead to a fuel leak and eventual uncommanded in-flight shutdown of the engine.

Recommendation

We recommend that you determine if fuel nozzles, P/Ns 6980200E03 thru 6980200E16 and corresponding P/Ns 1968M49P03 thru 1968M49P16, that have an S/N listed in Table 1 of this SAIB, are installed in your fleet. If you find any, we recommend you take appropriate actions per Parker Hannifin Corporation Service Bulletin 6980200-73-001 SB_R0, dated January 17, 2011. 1
