Boeing Retires Final 787-8 Test Aircraft ZA004 After 16 Years
Boeing retires ZA004, the last 787-8 test aircraft, after 16 years of flight testing and key contributions to engine and battery system improvements.
This article is based on an official press release from Boeing.
After nearly 16 years of service as a dedicated “flying laboratory,” Boeing has officially retired ZA004 (Registration N7874), the last remaining flight-test aircraft from the original 787-8 Dreamliner program. According to an official announcement from Boeing, the aircraft concluded its final mission on February 11, 2026, marking the transition of the Dreamliner family from a developmental phase into a fully mature operational stage.
The aircraft, which accumulated over 2,250 flight hours across more than 670 test flights, was flown one last time from Boeing Field (KBFI) in Seattle to Pinal Airpark (KMZJ) in Marana, Arizona. There, it will be stored and likely used for parts reclamation to support active fleets.
ZA004 holds a unique place in the history of the 787 program. As the fourth Dreamliner ever built, it was originally manufactured for Northwest Airlines prior to that carrier’s merger with Delta Air Lines in 2008. However, due to early program delays and the subsequent merger, the airframe was never delivered to a commercial customer. Instead, Boeing retained the aircraft, repurposing it as a dedicated testbed, a role it fulfilled for its entire operational life.
Unlike its siblings in the original test fleet, ZA001 through ZA006, ZA004 remained in service significantly longer. While the first three test aircraft were donated to museums and others were scrapped, ZA004 continued to validate new technologies for over a decade. John Murphy, the 787 Chief Project Engineer, highlighted the rarity of such a long service life for a test asset.
“Sixteen years of service with The Boeing Company, that’s a legacy few test airplanes achieve.”

Throughout its tenure, ZA004 served as a workhorse for systems reliability and propulsion testing. Boeing data indicates the aircraft was central to several critical engineering milestones that allowed the global 787 fleet to grow to over 1,100 aircraft.
The aircraft was the primary platform for testing upgrades to the Rolls-Royce Trent 1000 engine. It played a vital role in certifying the “TEN” and “XE” improvement packages, which were designed to resolve durability issues and extend time-on-wing for airline operators. Furthermore, following the global grounding of the 787 fleet in 2013, ZA004 was instrumental in validating the redesigned battery containment system and updated power distribution software, paving the way for the fleet’s return to service. In 2014, Boeing utilized ZA004 for its ecoDemonstrator program. During this phase, the aircraft tested more than 25 new technologies aimed at reducing noise and improving fuel efficiency. These tests included aerodynamic enhancements and software designed to optimize flight paths, many of which have since been integrated into commercial operations.
The retirement flight on February 11, 2026, was piloted by Captains Heather Ross and Craig Bomben. In a symbolic nod to the aircraft’s history, these were the same two pilots who sat in the cockpit for ZA004’s maiden flight on February 24, 2010.
According to Boeing, the decision to retire the aircraft was driven by economics. As the airframe approached a major heavy maintenance check (D-check), the company determined that maintaining a dedicated -8 testbed was no longer cost-effective given the maturity of the 787 platform.
“To the casual observer it looks like an old airplane, but it’s always been the future.”
Captain Heather Ross, Boeing Chief Pilot (via Boeing)
The retirement of ZA004 signals a definitive shift in the lifecycle of the 787 program. For years, the presence of a dedicated test airframe allowed Boeing to rapidly prototype fixes and upgrades, most notably during the battery crisis of 2013. The decision to retire the asset without a direct replacement suggests that Boeing views the 787-8 platform as sufficiently stable, requiring fewer experimental resources than it did during its volatile early years.
While the aircraft will no longer fly, its components will likely continue to keep other Dreamliners in the air, serving as a donor source for a fleet that now spans the globe. This move aligns with broader industry trends where mature airframe programs rely on operational data from airline partners rather than maintaining expensive, dedicated manufacturer test fleets.

Tata and Airbus Open India’s First Private H125 Helicopter Assembly Line
Tata Advanced Systems and Airbus inaugurate India’s first private-sector H125 helicopter final assembly line in Karnataka with deliveries starting in 2027.
This article is based on an official press release from Airbus and Tata Advanced Systems Limited (TASL).
Tata Advanced Systems Limited (TASL) and Airbus Helicopters have officially inaugurated India’s first private-sector helicopter Final Assembly Line (FAL) for the Airbus H125. Located in Vemagal, Karnataka, the facility represents a significant expansion of the aerospace manufacturing ecosystem in India, following the partners’ previous collaboration on the C295 military transport aircraft.
The inauguration ceremony, held on February 17, 2026, was conducted virtually by Indian Prime Minister Narendra Modi and French President Emmanuel Macron. The event underscores the deepening strategic partnership between New Delhi and Paris, particularly in the defense and aerospace sectors. On the ground in Vemagal, the ceremony was attended by senior officials including Indian Defence Minister Rajnath Singh, Tata Sons Chairman N. Chandrasekaran, and Airbus Helicopters CEO Bruno Even.
According to the official announcement, this facility will produce the H125 helicopter for both civil and military markets in India and the wider South Asian region. The first “Made in India” H125 is scheduled for delivery in early 2027, marking a shift from direct imports to localized manufacturing for this widely used rotary-wing platform.
The new Final Assembly Line is situated in the Kolar district of Karnataka, approximately two hours from Bengaluru. Reports indicate that the program investment is expected to exceed ₹1,000 crore. The facility is designed to handle the complete assembly, testing, and qualification of the helicopters before delivery.
Initial production capacity is set at 10 helicopters per year. However, TASL and Airbus have stated that the plant is scalable and can ramp up to 50 units per year depending on market demand. This scalability is crucial as Airbus projects a demand for approximately 500 H125-class helicopters in India and South Asia over the next two decades.
A key component of this project is the “Make in India” initiative. While the H125 is a French-designed platform, the manufacturing process in India will involve significant local content. Notably, Mahindra Aerostructures has been awarded a contract to manufacture the fuselage, the airframe skeleton, in Bengaluru. This ensures that critical structural components are produced locally rather than merely assembled from imported kits.
“This facility reflects the growing depth of India’s industrial capabilities… marking the first time the Indian private sector will undertake the manufacturing of a sophisticated rotary-wing platform.”
, N. Chandrasekaran, Chairman, Tata Sons
The Airbus H125 (formerly the AS350 B3e) is a single-engine light utility helicopter renowned for its high-altitude performance. It holds the world record for the highest-altitude landing and takeoff, having successfully landed on the summit of Mount Everest at 8,848 meters. This capability makes it particularly relevant for operations in India’s Himalayan borders.
The Vemagal facility will produce two primary variants:
Airbus Helicopters CEO Bruno Even highlighted the strategic importance of the military version, noting that the facility will ensure Indian armed forces remain “mission-ready” with localized support and maintenance.
The inauguration of the H125 FAL introduces a new dynamic to the Indian helicopter market, which has historically been dominated by the state-run Hindustan Aeronautics Limited (HAL). By entering the private sector, the Tata-Airbus partnership aims to introduce greater efficiency and competition.
The H125 will likely compete with and complement HAL’s indigenous Light Utility Helicopter (LUH). While the HAL LUH is a homegrown platform designed specifically for the Siachen Glacier’s requirements (6,500m+), the H125 brings a proven global track record with over 40 million flight hours. The H125 offers a higher maximum speed (~252 km/h) compared to the LUH (~235 km/h), though the indigenous platform may offer advantages in payload capacity and lifecycle costs due to its domestic IP.
Furthermore, the facility is positioned as an export hub. The H125’s suitability for mountainous terrain makes it an attractive option for neighboring nations such as Nepal and Bhutan, potentially expanding India’s footprint as a defense exporter in South Asia.
