 Exemption No. 10467 

 Regulatory Docket No. FAA-2012-0211 

Mr. Dustan Curtis 

Parent of Kason Dustan Clements 

2485 Route 620 

New Brunswick, Canada E3G 6P2 

Dear Mr. Curtis: 

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

decision, explains its basis, and the conditions and limitations of the exemption, including the 

date it ends. 

The Basis for Our Decision 

By letter received February 22, 2012, you petitioned the Federal Aviation Administration 

(FAA) on behalf of Kason Dustan Clements for an exemption from § 121.311(b) of Title 14, 

Code of Federal Regulations (14 CFR). That exemption, if granted, would allow Kason to 

exceed the specified weight limit for an FAA-approved child restraint system (CAReS, 

manufactured by AmSafe Corporation) during use of that child restraint system (CRS) aboard 

a United States (U.S). aircraft. 

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 Kason. 

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

those presented in your petition. In Grant of Exemption No. 9834 (copy enclosed), the FAA 

found that numerous people with physical challenges had previously completed flights using 

restraint systems that addressed unique physical needs regarding safety, support, and security 
2 

in the same manner of operations as described in this petition. The FAA further found that the 

petition, if granted, 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 do not differ materially from those presented by the petitioner in the enclosed grant 

of exemption; 

 the reasons stated by the FAA for granting the enclosed exemption 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. 40113 and 44701, which the FAA Administrator 

has delegated to me, I hereby grant Kason Dustan Clements an exemption from 

14 CFR § 121.311(b)(2)(iii)(B). In addition, any air carrier or commercial operator operating 

under part 121 while Kason is aboard its aircraft is granted an exemption from 

14 CFR § 121.311(b)(2)(iii)(B) to the extent necessary to allow Kason to exceed the specified 

weight limit for an FAA-approved CRS during use of that CRS aboard a U.S. aircraft. 

All operations under this exemption must be conducted with at least one of 

Kason Dustan Clements’ parents or a caregiver accompanying him. Kason may only occupy 

a passenger seat with no passenger seated behind his. In addition, Kason Dustan Clements’ 

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, 2012, unless sooner superseded or rescinded. 

Sincerely, 

/s/ 

Raymond Towles 

Acting Director, Flight Standards
