Airbus A350F First Flight Looms as Delivery Clock Ticks Down

Estimated reading time: 4 minutes

Airbus faces a narrowing window to certify its A350F freighter by late 2027, with industry watchers warning the first handover could slip into 2028 and force legacy fleet extensions.

Airbus is targeting late September 2026 for the maiden flight of its first A350F prototype, a milestone that will trigger a compressed certification campaign the manufacturer must complete to avoid pushing first delivery beyond its official end-2027 commitment.

The first prototype (MSN 700) rolled out of the final assembly line in November 2025 and has since undergone extensive ground testing, including main deck cargo loading system validation, cargo door cycling, and pressurization trials. A second prototype (MSN 701) is in assembly, with its first flight expected roughly two to three months after the lead aircraft. Reuters reported the September target could slip into early October if final preparations encounter snags. An Airbus spokesperson declined to comment on the specific timeline.

Airbus officially maintains that the first A350F delivery remains scheduled for the end of 2027. Chief Executive Guillaume Faury reiterated the goal during the company’s Q2 2026 earnings call. However, industry analysts are increasingly skeptical that the timeline is achievable.

Leeham News reported in August 2026 that first delivery could slip to 2028, a prediction the outlet first issued in October 2025. The concern centers on certification duration: completing a full flight test program and securing regulatory sign-off within roughly 15 months after first flight would require an unusually dense testing schedule. Faury himself acknowledged the uncertainty, stating that while the end-2027 target stands, deliveries “in rather significant numbers” would realistically begin in 2028.

The Air France-KLM group, which includes Dutch cargo subsidiary Martinair, has already responded to the schedule pressure. In 2025, the group reduced its A350F order from eight to six aircraft, three each for Air France Cargo and Martinair, down from four apiece originally. The group cited the need to balance capital expenditure with operational efficiency amid the delays.

Martinair currently operates three Boeing 747-400F freighters that the A350Fs are intended to replace. Because of the delivery delay, the group may extend leases on its existing Boeing fleet to maintain service continuity. The decision highlights a broader industry dilemma: operators waiting for next-generation freighters must choose between costly lease extensions or capacity gaps.

The A350F is a twin-engine widebody freighter based on the A350-1000 passenger platform, positioned to compete directly with Boeing’s 777-8F. It offers a maximum payload of 111 tonnes and a range of up to 8,700 km with full payload. Airbus claims the aircraft will deliver up to 20% lower fuel consumption and CO₂ emissions compared to previous-generation freighters with similar capability, and up to 40% better fuel efficiency versus older types such as the 747-400F. Over 70% of the airframe is composite material, making it 46 tonnes lighter than competing derivatives, according to the manufacturer.

The freighter also features the largest main deck cargo door in the industry, with a 4.3-meter width and 3.15-meter height clear opening, and is powered by Rolls-Royce Trent XWB-97 engines. It is certified for up to 50% Sustainable Aviation Fuel at entry into service, with a target of 100% by 2030.

Despite the schedule uncertainty, the A350F has accumulated over 100 firm orders from more than a dozen customers, roughly three times the total orders for the earlier A330F. Atlas Air placed the largest single order, 20 aircraft, in March 2026, marking a notable shift for the US cargo giant away from Boeing. Deliveries to Atlas are scheduled from 2029 to 2034. Other major customers include Air China Cargo, AviLease, Etihad Airways, and STARLUX Airlines, each with 10 aircraft on order.

Approximately 40% of the serial ground test procedures for the A350F had to be created or modified specifically for the freighter variant, reflecting the significant engineering differences from passenger A350 models. The coming weeks will determine whether Airbus can hold its September first-flight target and, by extension, whether the 2027 delivery promise remains credible. For operators like Martinair, the difference between a 2027 and 2028 entry into service is not academic, it is the difference between a planned fleet transition and an expensive bridge lease.
