aircraft Boeing Company Model 777-200 Airworthiness Directives; The Boeing Company Model 777-200 Series Airplanes

Unsafe Condition

Fire in the lower latch beam area that burns through an inadequate firewall may propagate into the strut, potentially weakening thrust reverser (T/R) parts and reducing structural integrity, leading to possible separation of T/R parts during flight and consequent damage to the airplane and injury to people or damage to property on the ground.

Install a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. Refer to Boeing Alert Service Bulletin 777-78A0066, Revision 2, dated April 8, 2010, for specific instructions.
