Final rule.

The Department of Transportation is modifying the T-100/T- 100(f) Traffic Reporting System. For traffic reporting purposes, the distinction between large and small aircraft is removed. All U.S. certificated and commuter air carriers and all foreign air carriers that operate to the United States will report their traffic movements in the T-100/T-100(f) Traffic Reporting System regardless of the size of aircraft used. Joint-service operations will be reported by the operating carrier. This rule modifies the current T-100 Reporting System to require U.S. carriers to report the detailed market and segment information for all their military, domestic all-cargo, and domestic charter flights. The detailed statistics from military operations will be withheld from public disclosure. The submission of Form 41 Supplemental T-1, T-2, and T-3 schedules is eliminated. The Department is requiring U.S. carriers that submit Form 41 financial reports to submit for each reported aircraft type, total aircraft hours, fuel consumed, and aircraft days assigned to service. Currently, there is a lack of market and segment data for domestic all-cargo, domestic charter and small aircraft operations. These changes will eliminate the data gaps for these rapidly growing segments of the air transportation industry.
