Sec. 32.53  Luminous safety devices for use in aircraft: Requirements 
for license to manufacture, assemble, repair or initially transfer.

    An application for a specific license to manufacture, assemble, 
repair or initially transfer luminous safety devices containing tritium 
or promethium-147 for use in aircraft, for distribution to persons 
generally licensed under Sec. 31.7 of this chapter, will be approved 
if:
    (a) The applicant satisfies the general requirements specified in 
Sec. 30.33 of this chapter;
    (b) The applicant submits sufficient information regarding each 
device pertinent to evaluation of the potential radiation exposure, 
including:
    (1) Chemical and physical form and maximum quantity of tritium or 
promethium-147 in each device;
    (2) Details of construction and design;
    (3) Details of the method of binding or containing the tritium or 
promethium-147;
    (4) Procedures for and results of prototype testing to demonstrate 
that the tritium or promethium-147 will not be released to the 
environment under the most severe conditions likely to be encountered in 
normal use;
    (5) Any quality control procedures proposed as alternatives to those 
prescribed by Sec. 32.55;
    (6) Any additional information, including experimental studies and 
tests, required by the Commission to facilitate a determination of the 
safety of the device.
    (c) Each device will contain no more than 10 curies of tritium or 
300 millicuries of promethium-147. The levels of radiation from each 
device containing promethium-147 will not exceed 0.5 millirad per hour 
at 10 centimeters from any surface when measured through 50 milligrams 
per square centimeter of absorber.
    (d) The Commission determines that:
    (1) The method of incorporation and binding of the tritium or 
promethium-147 in the device is such that the tritium or promethium-147 
will not be released under the most severe conditions which are likely 
to be encountered in normal use and handling of the device;
    (2) The tritium or promethium-147 is incorporated or enclosed so as 
to preclude direct physical contact by any person with it;
    (3) The device is so designed that it cannot easily be disassembled; 
and
    (4) The device has been subjected to and has satisfactorily passed 
the prototype tests prescribed by Sec. 32.101, Schedule B, of this 
part.
