Paul D. Finefrock, president of Thunderbird Propellers, Inc., and Thunderbird Accessories, Inc., both of Bethany, OK, and Marvin D. Thurmond, chief inspector for Thunderbird Propellers, each agreed to pay a $100,000 fine to settle a civil suit filed in U.S. District Court in Oklahoma City, for their role in falsifying aviation repair certificates. Finefrock also agreed to forfeit his FAA certificate for life. In a related case filed in U.S. District Court in Sherman, TX, both companies pleaded guilty to falsifying repairs—Thunderbird Propellers on 18 occasions involving aircraft propellers and Thunderbird Accessories on an aircraft turbo charger.
