1952, and that this amendment constitutes a reasonable and desirable limitation upon such operations.
With respect to the proposal to amend §40.507 [40.207] to require the time since last overhaul of airframe and engines to be included in the aircraft maintenance log, the Board concluded that this information was desirable for the proper assessment by the flight crew of certain irregularities experienced "in flight and that the provision of information from which time since last overhaul may be readily determined by the flight crew should be required.
The following provisions of revised Part 40 are discussed for the purpose of making clear the intent of the rule. The definition of "runway" in §40.5 [40.21] is not intended to alter materially the existing use of airport areas other than paved areas for the purpose of "over-run"
Section 40.32 [40.22] does not contemplate the re-approval of all off-airway routes presently contained in air carrier operations specifications. These specifications continue in effect in accordance with §40.18 (a) [40.12 (a)] as though they had been muted under the provisions of revised Part 40. The Administrator does have authority. however, under § 40.21 [40.15] to amend any operations specifications. "if he finds that safety in air transportation so requires or permits."
Although some of the words and phrases of §§ 40.70 [40.53] through 40.78 [40.61] have been rearranged or reworded, there is no intention to change,the meaning of, or the interpretation presently being adhered to, regarding the existing transport category performance limitations.
Although certain editorial changes have been made in § 40.202 [40.80] through 40.205 [40.86]. the intent of these sections is the same as the comparable provisions of present Part 61 regarding oxygen and protective breathing equipment.
The incorporation of the special airworthiness requirements. in §§ 40.110 [40.300] through 40.143 [40.333] and 40.150 [40.340] through 40.153 [40.343] is made without alteration of the intent of these provisions from presently effective regulations.
Interested persons have been afforded an opportunity to participate in the making of this regulation, and due consideration has been given to all relevant matter presented.
In consideration of the foregoing the Civil Aeronautics Board hereby revises Part 40 of the Civil Air Regulations (14 CFR. Part 40. as amended) effective October 1. 1953, to read as follows:
