Incident Overview
During pushback, a flight attendant was contacted by the lead flight attendant who asked if the crew rest area was secure. The attendant confirmed it was secure and then visually checked again, discovering the door was ajar. Concerned that a passenger may have entered the area, she went over and climbed the stairs to inspect the rest area.
On her way down, she believes she misplaced a foot on the narrow stairs and fell, breaking her arm in three places. After a few seconds, she got up and contacted the lead flight attendant, who then informed the captain. As a result, the aircraft was towed back to the gate.
