Abstract: Employee #1 was in the bucket of a TECO Saturn V aerial lift, having just completed trimming a dead tree. He was raising the fully extended boom to stow it on the truck when the boom failed and dropped approximately 12 ft to the ground. Employee #1 was tied off the bucket and rode it to the ground. He sustained a compound fracture of his left leg and internal injuries; he was transported to the hospital, where he was pronounced dead on arrival by the medical examiner. Subsequent investigation revealed that the boom turret had separated from the pedestal at the rotation bearing. At least 10 of the 24 bolts had visual indications of metal fatigue and/or of having been subject to overloading prior to the accident.
