Unsafe condition

This AD was prompted by reports of ice accretion on the airplane wing due to the failure of certain anti-ice piccolo tubes in the wing outboard slats. We are issuing this AD to detect and correct manufacturing defects in the anti-ice piccolo tubes in the wing outboard slats. This condition could lead to undetected significant ice accretion on a wing, resulting in loss of control of the airplane.

Affected ADs

None.
