For the airframe, there are only a few airworthiness directives (ADs) on the 230's that need worrying about.

IMPORTANT EDITORIAL:  You are responsible for your aircraft's safety.  You should always check with an authoritative source for recent airworthiness directives.  The FAA now has a searchable AD database.

• 53-16-01:  A recurring 100 hour trim tab inspection, which is concerned with sloppiness in the trim tab actuation system.  Sloppiness can usually be solved by new bolts.
• The main landing gear drag strut attachments on the rear spar are subject to a repetitive inspection for cracks.  This AD actually doesn't apply to 14-19-2s, but does apply to the Cruisairs and generally seems like a good inspection to perform on all low-wing Bellancas.
• 76-08-04:  The least necessary AD for a plane that is reasonably maintained, this requires a recurring inspection at every annual for wood rot.  In its simple form this is simply tapping a screwdriver butt along the spars of each wing listening for mushy "thunks" which may indicate wood rot in that region of the wing.
• 63-06-02:  This AD concerns rudder bellcrank hole elongation and is discussed separately here.
• The Hartzell propeller is unfortunately subject to a very expensive recurring inspection AD that requires a teardown and NDT inspection to look for propeller blade cracks in the blade root and blade clamps.  The initial inspection is required within 100 hours of issuance of the AD, and repeats every 250 hours.
