Service Bulletin for the Aircraft Maintenance Stand, Engine Access Stand and the Landing Gear Access

May 18, 2016

Subject:  Cylinder mounting step shifts position

Models Affected: 

Aircraft Maintenance Stand - DF071554-06

Engine Access Stand - DF071554-06S

Landing Gear Access Stand - DF071592-03

Problem: Ladder Rung shifts position when ladder cylinder is raised or lowered

Reason: Due to elongation of holes during bending process mounting holes cause a misalignment of step when the cylinder is actuated

Solution: The bolts for the mounting step must be removed, then the holes must be aligned. The holes are then to be reamed out to fit bearing in and a new set of bolts are installed. This Removes the problem of extra clearance and stiffens the assembly to stop it from shifting
