 Exemption No. 10704 

 Regulatory Docket No. FAA-2013-0060 

Ms. Tammy Humby 

Parent of Madisyn Humby 

264 Grey Fox Drive 

Kitchner, ON N2E3P2 

Dear Ms. Humby: 

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

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

including the date it ends. 

The Basis for Our Decision 

By letter received January 22, 2013, you petitioned the Federal Aviation Administration 

(FAA) on behalf of Madisyn Humby for an exemption from § 121.311(b)(2)(iii)(B) of 

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

Madisyn Humby 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 Madisyn Humby. 

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. 

 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 Madisyn Humby exemption from 

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

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

14 CFR § 121.311(b)(2)(iii)(B) to the extent necessary to allow Madisyn Humby 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 

Madisyn Humby’s parents or a caregiver accompanying her. Madisyn Humby may only 

occupy a passenger seat with no passenger seated behind her. In addition, Madisyn Humby’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 March 30, 2015, unless sooner superseded or rescinded. 

Sincerely, 

/s/ 

John M. Allen 

Director, Flight Standards Service
