(c) Replacement of the half sleeves in accordance with paragraphs (a) and (b) may be discontinued when the flexirac union on the main gear box oil pump is reinforced in accordance with Aerospatiale Service Bulletin No. 65.82 dated October 25, 1971, or an FAA- approved equivalent.

This amendment is effective upon publication in the Federal Register as to all persons except those persons to whom it was made immediately effective upon receipt of the telegram dated June 15, 1972, which contained this amendment.
