In the short-term, 3-years after the effective date of the final rule, airlines must:

• Ensure newly delivered 125+ seat aircraft include lavatories with key accessibility features, including a grab bar, call buttons, and a privacy barrier (i.e., screen if person with a disability is unable to fully close the lavatory door using the on-board wheelchair). Airlines are not required to retrofit existing single-aisle aircraft unless the airplane’s lavatory is replaced;

• Store an accessible on-board wheelchair (OBW) in the cabin of all 125+ seat aircraft that includes sufficient arm and back support, leg restraints, and that aligns with the aircraft seat for safe seat transfer; and

• Require flight attendants to complete annual hands-on and other training on OBW storage, passenger transfer to the OBW, and passenger transport to the lavatory.

In the long-term, all single-aisle aircraft with 125+ seats that are ordered within 10 years and delivered within 12 years of the final rule effective date are required to include at least one fully accessible lavatory that is large enough to accommodate a person with a disability and an attendant (both equivalent in size to 95% percentile male).
