(61F) Main Cabin Cargo Door Hydraulic System (Same as 55F) O.C. See Note * (61F) Cylinder Assembly, Main Cabin Cargo Door Actuating O.C. See Note * NOTE:
* The design of the main cabin cargo door installation is such that in the normally latched and locked position, it can be structurally compared to any fixed portion of the fuselage.
It is only when the door is actuated open on the ground during cargo loading operations that the heaviest loads are incurred. These loads would be greatest at the upper door hinge and hydraulic actuating cylinder attach points. The door seal would also be subject to damage at this time.
Thus, door utilization establishes inspection frequency.
Under these conditions, Douglas suggests the following procedure for purposes of inspection.
(1) Conduct a general visual area inspection of the upper cargo door hinge attachments, door jamb, door actuating cylinder attachments, door seal and latching mechanism at the scheduled "D" service following use of the aircraft in cargo configuration.
(2) If the aircraft is operated solely in the passenger configuration, conduct a general visual area inspection (as above) no later than "E" frequency.
