Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2019-02-03, which applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2019-02-03 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2019-02-03, the manufacturer has developed a new fire handle design that will eliminate the need for the airworthiness limitations required by AD 2019-02-03. This proposed AD would retain the requirements of AD 2019-02-03 and would require incorporation of an airworthiness limitation which applies only to certain airplanes. This proposed AD would also require replacing or modifying certain engine fire control panels, which would terminate the revised airworthiness limitation when a certain condition is met. The FAA is proposing this AD to address the unsafe condition on these products.
