## Discrepancy

(CAN) THIRD OCCASION THAT THE COMPRESSOR SECTION HAD BECOME DIFFICULT TO TURN DUE TO COKING AROUND LABYRINTH SEAL AT INJECTION WHEEL.  ONLY SOLUTION IS TO REMOVE ENGINE M.O.2 SECTION SENT TO OVERHAUL FACILITY FOR REPAIR. TURBOMECA IS NOW LOOKING INTO THIS PROBLEM DUE TO OTHER OCCURRENCES OF THIS PROBLEM.
