MusgraveSubject: Suspended Load Operations Description of Driving Event: Solid rocket motor (SRM)/orbiter processing and stacking requires personnel to p
2、erform tasks under suspended loads, increasing risk of injury/loss of personnel or flight hardware. personnel work under a suspended static load while processing SRMs and while the orbiter is in the vertical position to remove landing gear pins. An engine/turbo pump change requires personnel to work
3、 under the main engine area. Personnel work under a suspended load when the orbiter is mated/demated to the shuttle carrier aircraft to remove/install landing gear pins and during installation/removal of the orbiters maneuvering system pod.Lesson(s) Learned: Failure of a critical item lifting device
4、 (crane, hydraset, or lifting beam) may result in serious injury/loss of personnel or flight hardware.Recommendation(s): Minimize work time under suspended loads and modify lifting devices to use DC motors to eliminate erractic trolley and bridge movement.Evidence of Recurrence Control Effectiveness
