3D Aero HPT blade
**** Hidden Message ***** 2002M52P04/P05 Blade<BR>Shank cracking - 4 liberation events , last event Oct 03’<BR>1. Monitoring high-cycle operators 11 to 12.5K cycles<BR>• Southwest 42 or 59 engines complete – remaining completed by Jul 04’<BR>• Xaimen 3 engines at 12K , working the plan, spare engines concern<BR>• SAS has 5 engines at 11K, working along with P09 sampling plan<BR>• TAP w/8 engines approaching 12K – a lot of work completed, need closure<BR>• Eurowings has 2 engines 11K – working negotiations<BR>2. Investigating returned blade sets–11200 blades inspected ~ 6% confirmed cracked<BR>3. 361 engine sets remain in the field – 308 CNY(1 or more) and 53 Mad (thin coating)<BR>Root TE cracking – no field events<BR>1. Operators continue the great job of BSI’ing for this condition<BR>2. Of 263 engine sets of blades removed – 147 removed for TE cracks, (75) 7B & (72) 5BP<BR>3. Of the 361 engine sets in the field – 36 being monitored with TE root carcks<BR>Transition Zone Cracking – no field events<BR>1. Investigating blade from ESN874 Ford BBJ – 9779 cycles with a thru wall crack CV side<BR>#1 cavity<BR>2. Total events – 2 field engines with thru wall cracks with 9600 –9700 cycles, 1-CC,1-CV<BR>CFM56-7<BR>CFM56-5BP<BR>3D Aero HPT blade<BR>3D Aero HPT blade<BR>2002M52P09/P11 Blade<BR>Shank Cracking – no liberation events<BR>1. PCB approval to sample 7 high-cycle engines – CNY coated<BR>2. SAS has agreed on three –7’s, high cycle 12217, begins April 04’<BR>3. Southwest, GOL, Jet Airways,Braathens and Air Europa other possible<BR>-7 engine customer sampling – high cycle 11K<BR>4. 1558 ( –7) engines contain P09/P11 blades, 326 are CNY coated<BR>5. 5B/P customer Air France will pull 2 engines, timing TBD, now at 10.5K<BR>6. Looking at other high-cycle 5B/P operators Croatia and Aer Lingus –<BR>only 10K<BR>7. 7 out of the top 10 highest cycle 5B/P engines are Mad coated blades<BR>8. 735 5B/P engines contain P09/P11 blades, 143 are CNY coated<BR>9. Analysis of~ 2400 blades removed for other reason, found 1% cracked<BR>3D Aero HPT blade<BR>1975M10P03 Blade<BR>Introduction into production engines this month – 10 sets on-hand<BR>1. New shank geometry – addressesType 1(shank cracking) and TZ cracking<BR>like the M10P01 blade<BR>2. Thin shank coating same as the M52P14 and M10P01<BR>3. N5- chemistry to eliminate Yttrium from casting – YtO2 @ airfoil separations<BR>4. Like M52P09/11/14 has TE root cracking fix - CV platform holes<BR>5.
