REFURBISHED ENGINES T5 TRIM REVIEW Background Affected 12 engines post 1500 hour hot section inspection (HSI) Applied to engines processed at facilities with no test cell T5 trim may vary from original production and reduce engine time on wing Requirement for HSI test re-trim revised in EMM – March 2013 Special Instruction issued for field test – April 2013
Status P&WC DAA letters issued for 10 engines to recommend continued operation; 6 no trim change, balance had trim change <15 degrees One engine removed for overspeed (pilot induced) Awaiting final data for one engine
FUEL PUMP COUPLING SHAFT Chapter 5 Inspection Background Corrosion/wear on spline coupling Potential IFSD if not detected Possible Causes Depletion of chromium plating Lubricating oil mist restriction Solution 600 hr inspection (cotton swab check) Reduced wear limit at overhaul Spline inspection (pump removed): 1,500 hrs if pump < 3000 hrs TSN 300 hrs if pump >3000 hrs or overhauled before 2007 Reminder When installing pump, lubricate spline with oil only Ensure hole in AGB drive shaft restrictor is free of obstruction
EEC CONNECTOR CORROSION Background: EEC reversion to MEC mode
Cause: Water ingress into the J2 connector (airframe interface) caused corrosion to several pins
Recommendation: Perform recommended inspections, increase frequency based on experience Apply contact enhancer per maintenance manual
