Unsafe Condition
The left-hand rear mount link assembly was redesigned and certified in 1999, and the FAA subsequently issued AD 2000-12-08, mandating the replacement of the affected left-hand rear mount link assembly with a part eligible for installation. Later, analysis from the aircraft manufacturer of stress loads in their extended service goal mission profile revealed loads during the take-off phase that were not included at certification. These additional loads result in a reduced life limit on the left-hand rear mount link assembly.
