Dear Ms. Crombie: 

Exemption No. 11248 

600 Independence Ave .. S W 

Washington. DC 20591 

Regulatory Docket No. FAA-20 15-0749 

This letter is to inform you that we have granted your request for exemption. It transmits our 

decision, explains its basis, and gives you the conditions and limitations of the exemption, 

including the date it ends. 

The Basis for Our Decision 

By letter posted to the docket on March 25, 2015, you petitioned the Federal Aviation 

Administration (FAA) on behalf of your daughter Casey Crombie Baylis for an exemption 

from § l21.3ll(b) of Title 14, Code of Federal Regulations (14 CFR). That exemption, if 

granted, would allow Casey to exceed the specified weight and/or height limit for an FAAapproved child restraint system (CAReS, manufactured by AmSafe Corporation) during use of 

that child restraint system (CRS) aboard a United States (U.S).-registered aircraft. 

In Casey's case, since she is an adult, an exemption must also be granted from the requirement 

in § 121.31 I (b) that the individual be a "child." However, the reasons for requesting this 

exemption do not differ materially from those presented by other petitioners, and the reasons 

stated by the FAA for granting other exemptions also apply to the situation you present. 

The FAA has determined that good cause exists for not publishing a summary of the petition 

in the Federal Register, because the requested exemption would not set a precedent, and any 

delay in acting on this petition would be detrimental to Casey. 

AFS-15-925-E

The FAA has issued grants of exemption in circumstances similar in all material respects to 

those presented in your petition. In Grants of Exemption Nos. 7831 and 8264 (copies 

enclosed), the FAA found that numerous persons with physical challenges had previously 

completed flights using restraint systems. The use of these restraint systems addressed unique 

physical needs regarding safety, support, and security in the same manner of operations as 

described in this petition. The FAA further found that the petition would not set any new 

precedents regarding the use of restraint systems by persons with disabilities. 

Having reviewed your reasons for requesting an exemption, I find that-

• they are similar in all material respects to relief previously requested in the enclosed Grant 

of Exemption Nos. 7831 and 8264; 

• the reasons stated by the FAA for granting the enclosed Grant of Exemption Nos. 7831 

and 8264 also apply to the situation you present; and 

• a grant of exemption is in the public interest. 

Our Decision 

Under the authority contained in 49 U.S.C. §§ 106(t), 40113 and 44701, which the FAA 

Administrator has delegated to me, I hereby grant Casey Crombie Baylis an exemption from 

§ 121.311 (b). In addition, any air carrier or commercial operator operating under part 121 

while Casey is aboard its aircraft is granted an exemption from 14 CFR § 121.311 (b) to the 

extent necessary to allow her to exceed the specified weight and/or height limit for an FAAapproved CRS, during use aboard a U.S.-registered aircraft. 

All operations under this exemption must be conducted with Casey's parent or caregiver 

accompanying her. Casey Crombie Baylis may only occupy a passenger seat with no 

passenger seated behind her. In addition, Casey's parent or caregiver must carry a copy of this 

exemption and advise the air carrier about the contents of the exemption at least 48 hours 

before the date of each flight. 

This exemption terminates on April 30, 2020, unless sooner superseded or rescinded. 

Sincerely, 

John S. Duncan 

Director, Flight Standards Service
