## Discrepancy

THE WEDGE (LENS) PN 65C187-001 OF THE AIRSPEED INDICATOR BEZEL ASSEMBLY (PN 1U2202-007)  HAS CRACKED.  THIS CAUSES A STATIC SIDE LEAK OF THE INSTRUMENT.  APPEARS THE LIGHT ASSEMBLY THAT PROVIDES THE BACK LIGHTING IS BECOMING TOO HOT AND CRACKING, THE POLY-CARBONATE MATERIAL THAT THE WEDGE IS MADE FROM.  AIRSPEED INDICATOR IS APPROX 4 YEARS OLD WITH 151.0 TOTAL HOURS (TACH TIME).
