license.

[[Page 858]]

    (b) After a license has been issued, a licensee must apply to the 
FAA for modification of the license if--
    (1) The licensee proposes to conduct an RLV mission or perform a 
safety-critical operation in a manner not authorized by the license; or
    (2) Any representation contained in the license application that is 
material to public health and safety or the safety of property is no 
longer accurate and complete or does not reflect the licensee's 
procedures governing the actual conduct of an RLV mission. A change is 
material to public health and safety or the safety of property if it 
alters or affects the--
    (i) Mission rules, procedures, checklists, emergency plans, and 
contingency abort plans, if any, submitted in accordance with Sec. 
431.39
    (ii) Class of payload;
    (iii) Type of RLV;
    (iv) Any safety-critical system;
    (v) Type and container of the hazardous material carried by the 
vehicle;
    (vi) Flight trajectory;
    (vii) Launch site or reentry site or other landing location; or
    (viii) Any safety system, policy, procedure, requirement, criteria, 
or standard.
    (c) An application to modify an RLV mission license must be prepared 
and submitted in accordance with part 413 of this chapter. The licensee 
must indicate any part of its license or license application that would 
be changed or affected by a proposed modification.
    (d) The FAA reviews determinations and approvals required by this 
chapter to determine whether they remain valid after submission of a 
proposed modification.
    (e) Upon approval of a modification, the FAA issues either a written 
approval to the licensee or a license order amending the license if a 
stated term or condition of the license is changed, added, or deleted. 
An approval has the full force and effect of a license order and is part 
of the licensing record.
