## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2010-26-01, which applies to certain The Boeing Company Model 777-200 series airplanes. AD 2010-26-01 requires installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. Since AD 2010-26-01 was issued, the agency received a report that the T/R affected by AD 2010-26-01 has the potential to be installed on airplanes outside of the applicability of that AD. This proposed AD would retain the requirements of 2010-26-01. This proposed AD would also add airplanes to the applicability. For those airplanes, this proposed AD would require an inspection to determine if the installed T/R has an affected part number and, if an affected part number is found, installation of a new insulation blanket. The FAA is proposing this AD to address the unsafe condition on these products.
