Brief Description: Drilled Firewall Nose Gear Access Hole
Drawing OP-33 calls for a 3/4" diameter hole drilled through the firewall to access nosegear leg bolt. I marked the hole location as shown on OP-33 and used my step drill to make the 3/4" hole. I deburred the edges. Once the gear leg is installed the hole is covered with an FF 3/4" firewall plug and Prosealed.
