The 727 was then deliberately flown into the ground under remote control. 43: 162: 401: 365:

This system was very cumbersome, was very susceptible to damage, and thus has been removed

The most unusual airstair design was found on the Lockheed L-1011, which was a full-height airstair that was stored in a cargo compartment and allowed access from the right aft passenger door to the ground. This design was ultimately so large and heavy, and it took up valuable cargo space, that it

made this design popular. The stairs are actually part of the door rather than an attached stair. This design is efficient and because the aircraft which use it sit low to the ground, the design can stay simple and not add complexity or weight, one of the biggest problems with airstair assemblies.

STC's have been previously issued to subsequent manufacturers including Kaiser Aerospace, WAPCO, and Advanced Aerospace. On-Board Folding Airstairs can be found in use on many U.S., Foreign Military, and Government Aircraft, including the Boeing E4B as well as VIP aircraft around the world. The

On-Board Folding Airstairs is a multi-section (3, 4, or 5 segment) airstair that can be installed at either the forward, center, or aft doors. When retracted/closed, the airstair sits on a track and is typically stowed in a closet either Forward, Aft, or Transverse.

Another widespread type of airstair is used for forward doors. The stair folds and stows under the floor of the door and is deployed from the fuselage immediately below the forward door. This type of airstair is found on many short-range aircraft such as

The most common type of airstair is found in most business aircraft, regional jets, and other small airliners, which is a stair built into the inside of the main passenger door, which is lowered to the outside. Aircraft such as the
