TheAirbus A350F, much like Boeing’s rival Boeing 777-8F cargo jet, has had its service entry delayed. It is worth keeping in mind that not all freighters are purpose-built, as many are conversions from older passenger aircraft. New ICAO regulations are coming into force in 2027, and Boeing has to deliver its final 27 Boeing 767-300Fs and 56 777Fs by then. The FAA has granted an extension to 2033, but the regulations remain in force internationally.
