Unsafe condition
This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address fatigue cracking on the wing and winglet. This condition, if not addressed, could result in the inability of a principal structural element to sustain limit loads, which could adversely affect the structural integrity of the airplane.
Affected ADs
This AD affects AD 2020-01-18, Amendment 39-19824 ((85 FR 5304, January 30, 2020); corrected February 26, 2020 (85 FR 10969)) (AD 2020-01-18).
