Requires inspection of the mass-balance weights of the elevators, ailerons, and rudder, as well as their attached parts, for corrosion and any necessary replacement. Prompted by findings of corrosion in the mass-balance weights of the control surfaces. This condition could lead to loss of the mass or detachment of the mass-balance weights, resulting in an unbalanced control surface that could cause flutter and possible loss of airplane control.
