Rev. Rul. 67-398

Revenue Procedure 67-6, C.B. 1967-1, 576, announced a program for reviewing rulings published in the Internal Revenue Bulletin prior to 1953 for the primary purpose of identifying and declaring obsolete those rulings which, although not specifically revoked or superseded, are not considered determinative with respect to future transactions.

In accordance with that program, a review was made of those rulings dealing primarily with engineering matters and it was found that certain rulings were not determinative with respect to future transactions because (1) the applicable statutory provisions or regulations had been changed, (2) the ruling position was specifically covered by statute or regulations, or (3) the facts set forth were not sufficient to permit application of the current statute and regulations. Accordingly, Revenue Ruling 67-123, C.B. 1967-1, 383, declared obsolete certain rulings published prior to 1953.

Upon further review of rulings dealing primarily with engineering matters, the additional rulings listed below have been found to be not determinative with respect to future transactions and they are hereby declared obsolete.
