b. At intervals not exceeding 300 hours time in service.

                   4. Before exceeding 10000 hours time in service after strap modification or before 20000 hours time in service after manufacture, whichever occurs first.
                This Amendment becomes effective on 21 January 2010.
Background:     The original issue of this directive mandated inspections of the most likely locations for cracking and damage, included a strap modification to provide fail-safe ability and introduced a fatigue life limitation.

                Amendment 1.  Added additional wing stations to the inspection to improve fail safe capability and included all possible locations instead of the most likely locations.

                Amendment 2.  Required an additional inspection of the strap installation.  Also added a note on the Maximum weight of a Beech 18 variant.

                Amendment 3.  Following the cracking of some strap installations with foreign operators the threshold for strap inspections was amended.  Calendar life limit was removed.

                Amendment 4.  Reduced the intervals for the strap inspection following the failure of a strap from an operator.

                This Amendment refers to the State of Design directive for inspection requirements with the halving of intervals for welded repairs/modifications to the truss.
