## Discrepancy

TESTED NR 1 PROPELLER ALTERNATE FEATHER SWITCH ON PROP CONTROL PANEL USING CDS AND ARCDU IAW AMM 61-20-41-710-801. FOUND CHANNEL 1A TO OPERATE NOTMALLY BUT CHANNEL 1B STAYS ON WITH THE SWITCH IN THE ON AND OFF POSITIONS. REPLACED THE NR 1 ALTERNATE FEATHER SWITCH LIGHT ASSEMBLY IAW AMM 20-30-7-00/400-801. OPERATIONAL CHECKS GOOD.
