Lessons Learned - Emergency Equipment Design to Preclude Failures (Shuttle Crew Equipment Flotation Bladder) due to Abrasive Zippers
Year: 1991
Abstract: Description of Driving Event:
A bladder on a shuttle crew emergency rescue equipment inflatable flotation assembly was abraded by the zipper on the flotation sleeve, causing it to leak. Three of the flotation assemblies were flown on the orbiter for two flights and used twice in training sequences, which resulted in the zippers wearing and cutting the bladder where it passes around an emergency oxygen bottle. The corrective action taken was to add a zipper guard flap to all existing sleeves and to units to be manufactured.
