FAA is evaluating a future amendment to its regulations to permit firefighters to be transported to and from the site of a wildfire aboard certain restricted category aircraft when the purpose of that transportation is to permit those firefighters to perform ground wildfire suppression. The amendment would apply to civil aircraft operations and public aircraft operations when the restricted category aircraft is owned by a civilian operator. This action is in response to a statutory mandate, and FAA has determined it needs additional information to address both the mandate and the assessment of its economic impact. This advance notice of proposed rulemaking invites public comments on the current availability of firefighter transportation resources, hindrances and needs influencing their transport, and cost-benefit considerations affecting the transport of firefighters on certain aircraft.
