Alert 11 – 26 Inattention Results in Damaged Monkeyboard


While pulling a stand of drill pipe from the mouse-hole the top drive hit the monkey board causing damage to the board and the top drive. The crew had just made up a stand of drill pipe in the mouse-hole and was pulling the stand up to make a connection. However, during this operation, the driller forgot to retract the top drive and while the stand was being lifted into place, the elevators/bails crashed into the monkey board.
