Boeing 747-200

Dow Aero holds an airstair supplemental type certificate (STC), number SA800NM, for Boeing 747-200 aircraft.

Our automated rapid deployment airstairs are self-contained assemblies that are built to withstand normal day-to-day use in most environments. The airstairs mount directly to the cabin floor of your Boeing 747-200 aircraft and can easily be stowed away in a non-obstructive compartment when not in use.

Dow Aero's Boeing 747 airstair weighs only 295lbs (133.81kg) and when combined with a carriage, the entire assembly tops out at 370lbs (167.83kg). Our airstair assemblies not only have integrated 115/208V AC for it's primary power source, but they also include integrated 24V DC for backup power. We offer customers the choice to use either MIL-H-5606 or Skydrol Hydraulic Fluid.

All of our Airstair Assemblies are Proudly Designed and Assembled in the USA
