Apache owners take note: A new FAA final rule is going to effect next month. This amendment adopts a new Airworthiness Directive (AD) that applies to certain New Piper Aircraft Inc. model PA-23, PA-23-160, PA-23-235, PA-23-250, and PA-E23-250 airplanes that do not incorporate a certain design flap control torque tube or torque tube assembly. This AD, which goes into effect on June 23, requires owners/operators to repetitively inspect the flap control torque tube for cracks, corrosion, wear, or elongation of the attachment bolt holes (referred to as damage), and requires the replacement of any damaged torque tube with either an improved design flap control torque tube or flap control torque tube assembly.
