Continuous Monitoring for Continuing Enhancements
Boeing continually monitors in-service aircraft performance to proactively identify areas where the design of current and future models can be enhanced.
These enhancements incorporate new discoveries and new technologies over the life of an airplane, improving the safety and operational efficiency of the Boeing fleet. Boeing also monitors events that occur to non-Boeing airplanes to identify issues that might apply to Boeing airplanes so preventative actions can be developed and implemented if necessary.
Boeing monitors service information and addresses any concerns discovered in the fleet through a formal and disciplined process. Through the process, Boeing gathers relevant data, identifies potential safety issues and determines appropriate action to address those issues.
This safety process includes participation at all levels of the company including experts from a variety of technical disciplines; senior leaders from engineering, flight operations and training; and executive leaders.
In addition, the executive leaders constitute the Boeing Aviation Safety Council, which formally oversees a unified safety plan rooted in the company's long history of continuously improving the design, assembly, operation and maintenance of Boeing airplanes. As part of the safety process, Boeing works with the U.S. Federal Aviation Administration (FAA). Together, using a program called the Continued Operational Safety Program, Boeing and FAA engineering teams thoroughly review data from in-service events.
Boeing also works with its customers to understand and address potential safety issues.
When safety-of-flight issues arise, Boeing, together with the FAA, takes appropriate action to mitigate the risk, and communicates airplane part or procedural changes to its customers.
Regulatory authorities typically convert those changes into mandatory airworthiness directives (ADs) if the issues affect safety of flight.
Permanent solutions to an issue may take longer to develop and implement, because changes to an airplane design must be thoroughly tested, analyzed, validated and re-certified. In these cases, interim mitigating action is used to assure fleet safety until the permanent solutions are available.
