-Riveted the 3 fillter retainer brackets to the snorkel -Drilled for nutplates on the tops of those same brackets -Deburred, dimpled and installed the nutplates -Dimpled the inlet ramp for the #8 screws for the previously installed nutplates -Drilled the 2 top retainer pieces for #8 screws and dimpled / deburred -Cut hole for alternator air source (AAS) door -Match drilled the AAS retainer ring and deburred / dimpled -C/S the snorkel for the AAS retainer ring install -Bent the AAS door stop per the plans -Matchdrilled #30 the left inlet ramp to the two inboard engine attach brackets and the angle brace that runs across the top. I then realized the taper I put on the angle brace is backwards. I'll have to re-fab another one tomorrow. Luckily I have the material.
