Instead of pins, case-hardened cotters were provided for fulcrums of the bearing spring equalisinging beams. This was a unique situation, until the phasing out of the Fulcrums. The new foundation's wall columns (now called "fulcrums") were set inward from the sub-basement wall. Fulcrums and a number of Il-76s, including the one-off AEW-AWACS prototype Il-76 "ADNAN 1".
