(1) Return to the factory those blocks which have serial numbers listed in paragraph 1A of the applicable service bulletin in accordance with paragraph 1C(2) of the applicable service bulletin; and

(2) Retain as serviceable those blocks which have serial numbers listed in paragraph 1A of the applicable service bulletin but are also marked as noted in paragraph 1C(2) of the applicable service bulletin.
