AD 2001-25-03 66 FR 63913

This amendment adopts a new airworthiness directive (AD) that applies to certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD requires you to inspect one time for understrength rivets on the elevator torque tube and rudder hinge and replace any understrength rivets. This AD is the result of CDC notifying FAA that understrength rivets were mixed in production supplies. The actions specified by this AD are intended to detect and replace understrength rivets in the elevator and rudder, which could result in failure of the control surfaces. Such failure could lead to a loss of control of the airplane in flight.
