Abstract
A boarding ladder includes an upper step having a first and second collar, a lower step having a left and right side selectively slidably engaged with the first and second collar, respectively, with the lower step selectively slidable between raised and lowered positions. Left and right extensions are pivotally engaged with the left and right sides, respectively, with the left and right extensions pivoting between folded and extended positions. The left and right extensions are selectively slidably engaged with the first and second collars, respectively, in the extended position. A method of lowering a boarding ladder includes pivoting a left and right extension of a lower step to an extended position, disengaging a retention member from an upper step and the lower step, and lowering the lower step from the upper step until a stop on each of the left and right extensions abuts the upper step.
