## Discrepancy

LOUD SQUEEL,  100 DB,  CAPTAIN`S SIDEWALL. STARTED GEAR UP THRU 11, REST AT 24,000. CABIN PRESSURE OK.  CLEANED LIGHT DEBRIS FROM SLIDING WINDOW SEAL. PRESSURISED HULL SIX TIMES, NEVER GOT A SQUEEL. HIGHEST PRESSURE TESTED WAS 4 PSID. WINDOW OPERATES SMOOTHLY WITH NO OBSTRUCTIONS. NO EVIDENCE OF LEAKAGE WHEN CHECKED FROM OUTSIDE.  FOUND WHERE FORWARD FRAME DRAIN TUBE WAS BEING CLOSED IN SEAL, HAS MINOR DEFORMATION OF SEAL NOW. REPLACED SLIDING WINDOW SEAL AND SECURED DRAIN TUBE TO FORWARD FRAME.  LEAK CHECKED OKAY.
