14 CFR Part 382 Nondiscrimination on the Basis of Disability in Air Travel (Air Carrier Access Act): Preamble and Section-by-Section Analysis (with amendments issued through July 2010)

382.63 What are the requirements for accessible lavatories? As under the present rule, only aircraft with more than one aisle must have an accessible lavatory. U.S. carriers are already subject to these requirements for new aircraft they ordered after April 5, 1990, or which were delivered after April 5, 1992. Foreign carriers must comply with respect to new aircraft ordered after the effective date of the rule or delivered more than one year after the effective date.

Also, if a carrier replaces a lavatory on an aircraft with more than one aisle it must replace the lavatory with an accessible unit. A carrier need not have more than one accessible lavatory on an aircraft, however. This requirement already applies to U.S. carriers for new aircraft they ordered after April 5, 1990, or which were delivered after April 5, 1992. It will begin to apply to foreign carriers on the effective date of the rule.
