The manufacturer's failure to provide inspection criteria for the BPSU compartment aileron control pulleys, which resulted in eventual pulley corrosion, and subsequent control stiffness when seized pulleys and water-soaked aileron cables froze together at altitude.  Factors included leaking BPSU bay access panel seals, precipitation, and freezing temperatures.
