Civil Air Regulations Amendment 40—1

Effective:	July 10, 1947
Adopted:	June 10, 1947

ELIMINATION OF CERTAIN AIR CARRIER PROVING FLIGHTS

Scheduled air carriers are presently required to conduct a proving flight over a proposed route even though it is a minor modification or extension of an existing route already flown by the air carrier. Under certain conditions the safety of the proposed operation is not advanced by such a proving flight and, where this is true, an undue burden is placed upon the air carrier. It appears that the public interest will best be served if a proving flight is not required where it is unnecessary in the interest of safety.

The purpose of this amendment is to authorize the Administrator of Civil Aeroneutics to omit the requirement of certain air carrier proving flights where he finds they are not essential to safety.

NOW, THEREFORE: Effective July 16, 1947, § 40.191 of the Civil Air Regulations is amended by adding the following clause at the end of the last sentence thereof: "unless the Administrator after investigation expressly finds (1) that the proposed route modification is minor and (2) that an actual flight is not essential to safety."
