Study Notes
Challenger Shuttle Disaster Background
- On January 28, 1986, the Space Shuttle Challenger was destroyed 73 seconds after launching from Kennedy Space Center, killing all seven crew members.
- The disaster was caused by the failure of an O-ring to prevent hot gases from leaking through the joint in the solid rocket motor during launch.
Investigation Findings
- The Rogers Commission found that the O-ring design had been a point of concern for several years prior to the disaster.
- Concerns about the O-ring design were either poorly communicated or ignored in favor of maintaining project delivery on-time and on-budget.
- The commission determined that the unusually cold temperatures at the time of the launch made the rubber O-rings inflexible, allowing gas to escape and ignite.
Weaknesses in Quality Assurance
- Risk management issue: categorizing the design flaw as an acceptable risk.
- Management structure with communication flaws, allowing managers to bypass Quality Management procedures.
- Failure to take prevention action, such as changing the O-ring material or adding temperature limitations to the rocket operation handbook.
Strengths of Quality Assurance
- Post-incident analysis and improvement: QA teams contributed to identifying root causes of the disaster and implementing necessary improvements.
- Commitment to transparency: documenting and reporting deviations or concerns.
- Enhanced training and education: increasing awareness of quality and safety requirements among engineers, technicians, and personnel.
Learned Lessons
- Prioritizing reliability and safety over schedule and budget.
- Enhancing risk assessment protocols.
- Improving communication channels.
- Continuous improvement in Quality Management Systems (QMS).
