## Discrepancy

DURING THE SCHEDULED 100HR INSPECTION, A 0.75" CRACK WAS DISCOVERED, EMANATING FROM THE OUTBD STATIC WICK BASE ON THE L/H ELEVATOR. THE STATIC WICK WAS REMOVED AND THE CRACK WAS STOP DRILLED USING A #40 DRILL BIT. A REINFORCING DOUBLER OF 2024T3, 0.025" THICK, MEASURING 2.7"X2.7" WAS INSTALLED ON THE BACK SIDE OF THE AREA, USING CR3213-4 RIVETS. THE STATIC WICK BASE WAS REINSTALLED. ELEVATOR BALANCE WAS CHECKED AND ADJUSTED TO A BALANCE WEIGHT OF +2.43 BY ADDING WASHERS TO THE BALANCE WEIGHT ATTACH BOLTS. THIS WAS WITHIN BALANCE WEIGHT LIMITS. CRITERIA FOR THIS REPAIR WAS GATHERED FROM THE CESSNA 208 STRUCTURAL REPAIR MANUAL 53-20-00, FIG 801, AND 51-75-00.
