Unsafe condition
This AD was prompted by the identification of a manufacturing defect on certain aileron bellcrank support brackets that resulted in insufficient material thickness of the affected lug attaching the support bracket to the rear spar of the wing. We are issuing this AD to detect and correct a defect of the aileron bellcrank support bracket, which, in the event of an aileron jam, could lead to failure of the support bracket and result in reduced controllability of the airplane.
Affected ADs
This AD replaces AD 2018-11-07, Amendment 39-19295 (83 FR 24399, May 29, 2018) (“AD 2018-11-07”).
