Brief Description: Drill Out Firewall Rivets for Battery Tray & Relay
I was only able to spend about a half hour working on the plane tonight. The plans indicate five rivets that needed to be drilled out on the firewall in order to attach the battery tray and double for the relays. Once this was done I riveted the nutplates onto the F-7127A-L/R battery tray mounting angles.
