Adopted by the Civil Aeronautics Board at its office in Washington, D. C., on the 6th day of December 1949.
Amendments 2-1, 3-1, 4a-3, 4b-l, 6-3, 13-1, 14-1, 15-1 adopted November 2, 1949, require the installation, after De cember 6, 1949, of a fireproof identifica tion plate on the several products manufactured in accordance with the requirements of each part. We are ad vised that certain manufacturers have as yet been unable to obtain the required fireproof plates, but that such plates can be obtained before March 7, 1950. We are therefore extending the date for compliance with these requirements until that time, so that deliveries of aircraft and aircraft components will not be in terrupted.
For the reasons stated above notice and public procedure hereon are imprac ticable and contrary to the public inter est, and the Board finds that good cause exists for making this regulation effec tive on less than 30 days notice.
In consideration of the foregoing the Civil Aeronautics Board hereby makes and promulgates a Special Civil Air Reg ulation as follows, effective immediately:
