The diligence and determination of the engineering team that has been investigating the cause of the incident on ZA002 earlier this month in Laredo has been exceptional.
Today we announced some of the findings from that investigation and the steps we will be taking to improve the power distribution panels on the 787.
That team has been tireless in their pursuit of understanding. They explored several possibilities and determined that the foreign debris is the likely cause of a short circuit or arc in the power distribution panel.
Whatever this foreign debris was, it wasn’t something big - such as a tool - it was probably something small. We’re taking the right steps to ensure the power distribution panels are better protected against foreign debris. In addition, we’re improving the 787’s software to help it better isolate faults.
The team will work just as diligently to complete the redesign and software updates as it did on the investigation. We will continue to update the Federal Aviation Administration as we progress through this process and move toward returning the 787 fleet to flight test.
These findings will no doubt have you asking question about the first 787 delivery and the program schedule. That is under review now by the program and as soon as we have a definitive answer, we’ll share it with you.
We test our airplanes vigorously to ensure they meet our high standards, aviation regulations and the expectations of our customers.
Every time we have a finding in testing, we get smarter about how to design our airplanes and how to conduct testing. The 787 has benefitted from what we have learned on the programs that came before it.
Our next test programs will benefit from what we have learned on the 787. And, the 787 will have the needed improvements before it enters revenue service. The test program is working.
