(ii) If one soft rivet and one hard rivet are installed on any of the four rod ends, within 200 flight hours or 12 months of the visual inspection required by paragraph (g)(1) of this AD, whichever occurs first after the effective date of this AD, replace the soft rivet with rivet part number MS20470AD4-12 in accordance with the Accomplishment Instructions, paragraph 7., of Beechcraft Mandatory SL MTL-27-07.
Unsafe condition
This AD was prompted by a report of rudder control pushrod failure during a production ground run caused by sheared rivets off of a rudder control pushrod. The FAA is issuing this AD to detect and address incorrect rivets. The unsafe condition, if not addressed, could result in rudder jam or loss of rudder control, which could lead to loss of control of the airplane during flight or ground operations.
Affected ADs
None.
