Air Carrier Access Act Technical Assistance Manual (2005)

If Passenger with a Disability Requests Private Screening

You must not require a private security screening for a passenger with a disability for any reason different from the reasons other passengers would be subject to a private security screening. However, if a passenger with a disability requests a private security screening in a timely manner, you must provide it in time for the passenger to board the flight. [Sec. 382.49(b)] If, however, you are able to conduct a security screening of a passenger with a disability without the need for a physical search of the person, you are not required to provide a private screening. [Sec. 382.49(c)]

Finally, under certain circumstances, safety considerations may require you to exercise discretion in making the above decisions. You must always seek assistance from the appropriate designated personnel in making such a decision.
