Unsafe condition

This AD was prompted by reports of corrosion on the horizontal stabilizer bearing supports at the contact surface to the horizontal stabilizer rear spar. We are issuing this AD to address corrosion on the horizontal stabilizer rear bearing supports and rear spar, which could lead to failure of the fitting and loss of one load path of the horizontal stabilizer attachment, and possibly result in reduced controllability of the airplane.

Affected ADs

None.
