Feature A - Main Boss and Hole

In Feature A, the main bosses hold the bearings which support the locking rod.

  • The hook on the landing gear door latches onto the locking rod to secure the doors in flight.

  • The locking rod carries the full load of the doors and the bosses have to be heavy enough to transfer the load into the uplock support.

The bosses are strengthened with additional material in the depth and width on both sides of the main wall to carry the full load. In the final design the bosses are 1.3 inches in depth with a diameter of 2.0 inches to accommodate the 1.187" diameter bushing hole.

Feature A does need to be changed.
