Completed this entire section in a day. Glad to finally start looking beyond section 29 though I stilll have riveting,mid cabin decks, gear and floor installation to complete in section 29.
Added aftermarket aluminum support inside of step tube at the area of where the pilot hole is drilled. Incremental support to prevent step tube from weakening.
Also, did not drill hole into bottom skin of airplane. Ordered Airward access panels for baggage floor to service steps if required.
