Russia’s SJ-100 Passes Key Water Ingestion Test for PD-8 Engines
Russia’s SJ-100 aircraft passed critical water ingestion tests with PD-8 engines, marking progress toward aerospace independence and certification by 2025.
Russia’s SJ-100: A Leap Towards Aviation Sovereignty with Successful Engine Tests
In the high-stakes world of civil aviation, the path from design to commercial flight is paved with rigorous testing. For Russia’s SJ-100 Commercial-Aircraft, a recent milestone marks a significant stride forward in its national ambition to achieve technological independence in the aerospace sector. The aircraft, powered by the newly developed, domestically produced PD-8 engines, has successfully passed a critical water ingestion test. This isn’t just a routine check; it’s a validation of Russia’s capability to build a reliable, modern regional jet using its own technology, a crucial goal in light of international sanctions that have restricted access to foreign components and systems.
The SJ-100, formerly known as the Sukhoi Superjet 100, has been systematically re-engineered to replace imported parts with domestic alternatives. The “heart” of this transformation is the PD-8 engine, a product of the United Engine Corporation (UEC), a subsidiary of the state-owned Rostec corporation. The successful completion of the water ingestion trials confirms that the aircraft’s propulsion system can withstand adverse weather conditions, such as operating on rain-flooded runways, without compromising safety or performance. This achievement moves the SJ-100 closer to full certification and, ultimately, to serial production, underpinning a broader strategy to revitalize Russia’s civil aviation manufacturing industry and ensure its long-term self-sufficiency.
The “Water Pool” Gauntlet: Proving Engine Resilience
To certify an aircraft for commercial use, Manufacturers must prove its systems can endure a wide range of environmental challenges. The water ingestion test is one of the most demanding of these trials. It is designed to simulate real-world scenarios like landing or taking off during a torrential downpour, where large amounts of water can be kicked up from the runway surface and drawn into the engines. Failure in such a scenario could lead to engine flameout or catastrophic damage, making this test a non-negotiable hurdle in the certification process.
The tests for the SJ-100 were conducted at the Gromov Flight Research Institute in Zhukovsky, near Moscow. A specially constructed basin, described as a “water pool” measuring over 70 meters long and 12 meters wide, was built on the runway. The test aircraft, numbered 97023, performed a series of high-speed runs through this pool to mimic the conditions of takeoff and landing in heavy rain. During these runs, the engines, as well as the aircraft’s auxiliary power unit (APU), were subjected to massive water spray. The trials also included the operation of the PD-8’s thrust reversers, which are used to help slow the aircraft upon landing and can exacerbate water ingestion.
The outcome was a resounding success. Officials confirmed that the ingestion of water did not negatively impact the operation of the PD-8 engines or the APU. According to Vadim Shirokih, the Chief of the Yakovlev Regional Aircraft Flight-Test Complex, the tests verified that water “does not interfere with the operation of the aircraft’s engines or auxiliary power unit.” This result provides critical data affirming the engine’s robust design and its readiness for all-weather operations, a key requirement for any commercial airliner.
“The PD-8 engines, developed by United Engine Corporation using advanced domestic technologies, showed stable and reliable performance during the ‘water pool’ tests, guaranteeing passenger safety under all weather conditions.” – Fedor Mironov, Deputy Director for Sales at UEC.
The PD-8 Engine: The Core of Russia’s Import Substitution Strategy
The development of the PD-8 engine is the centerpiece of the SJ-100’s import substitution program. The original Superjet 100 was powered by SaM146 engines, a joint venture between a French and a Russian company. Sanctions made continued reliance on this partnership untenable, forcing an accelerated push for a fully domestic powerplant. The PD-8 was developed by leveraging technologies from the larger PD-14 engine, which powers Russia’s MC-21 medium-range airliner. This approach allowed engineers to fast-track development while incorporating proven, modern design principles.
The engine is a testament to Russia’s advancements in materials science and aerospace engineering. It incorporates new Russian-developed alloys and features a fully domestic electronic control system, breaking free from dependence on foreign-supplied components. Its technical specifications are competitive, with a bypass ratio of 4.4 and a specific fuel consumption in cruise mode below 0.62 kg/kgf·h, indicating a focus on efficiency. The versatility of the PD-8 design is also notable, as engineers are adapting it for use on the Beriev Be-200 amphibious aircraft, a platform that operates in even more demanding water-based environments.
The successful water test is just one of several milestones the SJ-100 has recently achieved. The aircraft has undergone stability and controllability checks at high speeds, evaluations of its integrated control system in extreme flight attitudes, and testing of the PD-8’s thrust reversers. This comprehensive testing program is paving the way for the aircraft’s final Certification, which is anticipated by the end of 2025, with mass production slated to begin in 2026.
Conclusion: A New Chapter for Russian Civil Aviation
The successful water ingestion tests of the SJ-100’s PD-8 engines are more than just a technical achievement, they represent a pivotal moment in Russia’s quest for a sovereign and competitive civil aviation industry. By proving the reliability of its homegrown engine technology under harsh conditions, Russia has cleared a major obstacle on the path to deploying a fully domestic regional jet. This progress is a direct result of a focused national strategy to overcome the limitations imposed by international sanctions and rebuild its industrial capabilities from the ground up.
Looking ahead, the SJ-100 program is a cornerstone of a larger plan to manufacture over 600 domestic aircraft by 2030, replacing an aging fleet of Western-built planes. The establishment of 15 dedicated service centers is also planned to support this new fleet, creating a comprehensive ecosystem for maintenance and spare parts. The journey is far from over, but the steady progress of the SJ-100, marked by milestones like this successful test, signals a clear trajectory toward reviving large-scale domestic aircraft manufacturing and securing Russia’s place in the global aerospace landscape on its own terms.

Qantas Accelerates A380 Retirement to 2028 From 2032
Qantas moves A380 retirement to mid-2028, four years early, citing a A$610M fuel cost rise and mounting maintenance challenges.
Qantas Airways (QF) will accelerate the retirement of its Airbus A380 fleet by four years, phasing out the four-engine superjumbos starting in mid-2028 as the Australian carrier grapples with rising maintenance expenses and a surging fuel bill.
The decision, announced on August 27, 2026, alongside the airline’s full-year financial results, marks a definitive shift away from the original 2032 retirement target. Qantas cited the out-of-production status of the A380 and a recent A$610 million spike in fuel costs as primary drivers for the accelerated timeline, which aligns with an industry-wide transition toward more efficient twin-engine widebody aircraft.
Financial pressures and maintenance challenges
Qantas Group reported an underlying profit before tax of A$2.06 billion for the 2026 financial year, representing a 13.1 percent decrease compared to the previous year. The A$330 million drop in pre-tax profit was heavily influenced by fuel costs linked to the Middle East conflict. This fuel price volatility disproportionately impacted the operating economics of the four-engine A380 fleet.
With Airbus having ceased A380 production in 2021, operators face mounting challenges in sourcing parts and managing upkeep. According to reporting by Reuters, Qantas Group CEO Vanessa Hudson stated that the cost of the aircraft will increase over time regarding maintenance, alongside rising costs associated with operational disruptions.
Next-generation fleet transition
The accelerated retirement is facilitated by the airline’s ongoing fleet renewal program. Qantas expects its first Airbus A350-1000ULR, designated for its ultra-long-haul Project Sunrise routes, to arrive in April 2027. The carrier is also negotiating the conversion of 20 existing purchase right options into firm orders for additional Airbus A350s and Boeing 787 Dreamliners, with deliveries targeted from 2030.
Hudson emphasized that the influx of new aircraft enables the earlier phase-out of the 10 remaining A380s.
“With our first Project Sunrise A350-1000ULR to arrive in April, and more A350s and 787s on the way, it’s a new era for Qantas’ international fleet with these next generation aircraft set to transform the way our customers travel. This means we can commence the retirement of our A380 fleet from 2028.”
The exact conclusion date for the A380 retirement remains flexible. Aviation Week reported that Hudson expressed confidence in the delivery stream of replacement aircraft, noting that the airline will progressively update the retirement schedule as new widebodies enter service.
AirPro News analysis
We view the accelerated retirement of the Qantas A380 fleet as an inevitable consequence of current macroeconomic pressures intersecting with aging airframes. The A$610 million fuel penalty incurred this year highlights the vulnerability of four-engine operations in a volatile energy market. While the A380 remains popular with passengers, the transition to the A350 and 787 provides Qantas with superior route flexibility and significantly lower seat-mile costs. The shift from a 2032 retirement to 2028 reflects a pragmatic approach to fleet management, ensuring the airline is not left holding maintenance-heavy assets as the global supply chain for A380 components continues to shrink.

Icelandair Acquires 49% Stake in Maltese AOC for $686K
Icelandair Group acquired a 49% stake in a Maltese AOC holding company for USD 686,000 to expand EU operational flexibility.
Icelandair Group hf. has completed the acquisition of a 49% stake in a holding company controlling a Maltese Air Operator Certificate (AOC) for USD 686,000, securing a strategic foothold within the European Union regulatory environment.
The transaction, finalized on August 20, 2026, involves Fly Play Europe Holdco ehf., whose subsidiary holds the currently suspended Maltese AOC MT-85. The certificate was previously associated with the defunct Icelandic budget carrier PLAY, which ceased operations following its bankruptcy in September 2025.
Strategic expansion into Malta
In a press release issued on August 20, 2026, Icelandair announced the purchase from FPE hs., a fund managed by Isafold Capital Partners hf. The Airlines stated the acquisition is designed to increase operational flexibility and support the development of its primary hub at Keflavik International Airport (KEF).
The completion of the transaction remains contingent on reaching an agreement with the Transport Malta Civil Aviation Directorate (TMCAD) regarding the continued use of the certificate. Publicly available data from Transport Malta indicates that AOC MT-85 is currently suspended and has no Commercial-Aircraft registered to it.
Icelandair Group hf. CEO Bogi Nils Bogason outlined the company’s rationale in the official announcement.
“Acquiring a stake in a Maltese air operator certificate is primarily intended to increase operational flexibility, strengthen Icelandair’s competitiveness, and create new opportunities, all with the aim of supporting the continued development of our Keflavik hub and thereby safeguarding jobs and a strong operating environment for the Manufacturing industry in Iceland for the years to come,” Bogason said.
Origins of the AOC and future options
The Maltese AOC originally belonged to a subsidiary of PLAY. Following the budget carrier’s financial collapse in late 2025, creditors enforced security interests to recover the Maltese holding structure. Icelandair initially announced a Letter of Intent regarding the Acquisitions in April 2026 before finalizing the purchase in August.
As part of the agreement, Icelandair has secured options to increase its stake in Fly Play Europe Holdco ehf. at a later stage. The company utilized Arma Advisory as its financial adviser for the transaction.
AirPro News analysis
We view Icelandair’s move to secure a Maltese AOC as a calculated step to bypass the bilateral traffic right limitations inherent to its Icelandic registration. Malta has become a preferred jurisdiction for European operators seeking a flexible, EU-based Regulations environment. By acquiring an existing corporate structure rather than applying for a new certificate, Icelandair likely aims to accelerate its timeline for establishing a secondary European operating base, provided TMCAD approves the reactivation of the suspended certificate.
