This rulemaking would amend the existing reporting requirements in 14 CFR 234.13 concerning the loss, injury, or death of an animal during air transport. Under the existing rule, animal means any warm or cold blooded animal which, at the time of transportation, is being kept as a pet in a family household in the United States. This rulemaking would expand the definition of animal to also include all cats and dogs transported by an air carrier, regardless of whether or not it is kept as a pet in a family household. In addition, the existing rule applies to air carriers that account for 1 percent or more of domestic scheduled-service passenger revenues. The rulemaking would expand this to all U.S. carriers that operate scheduled service with at least one aircraft with a design capacity of more than 60 seats.
