Scaffolding apparatus and related methods are disclosed. An example scaffolding apparatus includes a beam defining a length between a first end of the beam and a second end of the beam opposite the second end. The length of the beam spans between a first side of a fuselage portion of an aircraft and a second side of the fuselage portion opposite the first side. A first connector is coupled to the first end of the beam. The first connector engages a first stringer on the first side of the fuselage portion to couple the first end of the beam to the fuselage portion. A second connector is coupled to the second end of the beam. The second connector engages a second stringer on the second side of the fuselage portion to couple the second end of the beam to the fuselage portion.

Scaffolding apparatus and related methods

A ladder includes a pair of generally curved side rails arranged in a spaced apart manner, a plurality of fixed rungs disposed between the side rails, a plurality of pairs of rung supports, and a plurality of hinged rungs. Each of the pairs of rung supports is horizontally aligned with each other and disposed on respective inner sides of the side rails. The rung supports are spaced apart from the fixed rungs along lengths of the side rails. Each rung support includes a flanged end portion having an aperture therein. Each hinged rung is associated with a respective pair of rung supports. Each hinged rung has a first end pivotally coupled to the flanged end portion of a first rung support in the respective pair of rung supports such that each hinged rung is pivotal between a secured position between the rung supports and a retracted position.
