Dow Aero holds a supplemental type certificate (STC), number SA8000NM, for Boeing 747-200 Airstairs.

Our automated rapid deployment Airstairs are self-contained assemblies which are manufactured to withstand normal day-to-day use in numerous environments and which allow your aircraft independence from ground service equipment. Our rigorous quality assurance standards, which includes certifications in ISO 9001:2015 and AS9100D, ensures we manufacture our Airstairs to the highest standards. 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 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 also include integrated 24V DC for backup power. We offer customers the choice to use either MIL-H-5606 or Skydrol Hydraulic Fluid.
