MT-Propeller Entwicklung GmbH has secured an amended Supplemental Type Certificate (STC) from the Federal Aviation Administration (FAA) to install its seven-blade “Silent 7” composite propeller on the Pilatus PC-12/47G. The approval, issued on June 02, 2026, expands the certified applications for the MTV-47 propeller system without requiring engine modifications.

The company publicly announced the Certification on June 11, 2026. The FAA approval (STC SA02742NY) follows the European Union Aviation Safety Agency (EASA) STC issued on January 22, 2026, and a Transport Canada Civil Aviation (TCCA) Letter of Acceptance from July 31, 2024. The upgrade targets operators seeking improved short-field performance and compliance with stringent European noise Regulations.

Performance and noise reduction metrics

According to MT-Propeller’s official STC data sheet, the MTV-47 installation delivers measurable performance gains for the PC-12/47G. The certified ground roll distance is reduced by approximately 10 percent, while the takeoff distance over a 50-foot obstacle decreases by 15 percent compared to the original four-blade metal propeller. The composite propeller has a maximum diameter of 102.36 inches (260 cm) and an installed weight of 221.8 pounds (100.6 kg), including the spinner.

Noise abatement is a primary feature of the “Silent 7” design. The manufacturer reports an approximate 4 dB(A) reduction in exterior noise levels. Inside the aircraft, cabin noise is reduced by 6 to 7 dB(A), depending on the specific seating location. This acoustic performance allows the PC-12/47G to comply with strict European noise standards, including Germany’s 2010 Landeplatz Lärmschutz Verordnung, enabling unrestricted operations at noise-sensitive airports.

Engine compatibility and North American expansion

The amended STC covers the PC-12/47G alongside previously certified models, including the PC-12, PC-12/45, PC-12/47, and PC-12/47E. The MTV-47 propeller is approved for use with Pratt & Whitney Canada PT6A-67B, PT6A-67P, and PT6E-67XP engines. MT-Propeller emphasized that the installation is a direct bolt-on upgrade requiring no modifications to the existing powerplant.

The FAA certification aligns with MT-Propeller’s recent efforts to expand its support infrastructure in North-America. In April 2026, the company announced the opening of MT-Propeller Canada Inc., a joint venture with AMK Aviation Inc. based in Murillo, Ontario. The new facility is designed to provide enhanced service, spare parts distribution, and field support for North American operators adopting the composite propeller systems.

We note a discrepancy in the performance figures marketed by regional distributors compared to the official certification data. While Finnoff Aviation Products, the exclusive North American distributor for the upgrade, cites a 20 percent reduction in ground roll and a 23 percent reduction in obstacle clearance distance, MT-Propeller’s official June 2026 STC data sheet lists more conservative figures of 10 percent and 15 percent, respectively. Operators evaluating the upgrade should base their operational planning on the certified flight manual supplements rather than distributor marketing materials. The addition of the PC-12/47G to the STC ensures that newer airframes can utilize the seven-blade system, which has become increasingly popular for operators flying into noise-restricted European airfields or backcountry strips requiring maximum short-field performance.

Honeywell Technologies finalized the spin-off of its aerospace division on June 29, 2026, officially dismantling the historic conglomerate to become a pure-play automation company.

In a press release issued on June 29, 2026, the Charlotte, North Carolina-based company confirmed the completion of the transaction, which establishes Honeywell Aerospace as an independent, publicly traded entity. The milestone concludes a multi-year portfolio transformation that began in 2023 and previously saw the separation of Solstice Advanced Materials.

Financial restructuring and market debut

Concurrent with the aerospace spin-off, Honeywell Technologies executed a 1-for-2 reverse stock split. According to reporting by Benzinga, the reverse split reduced the company’s issued and outstanding shares from approximately 634 million to roughly 317 million. The company also reduced its authorized common shares from 2 billion to 1 billion.

Honeywell Aerospace shares were distributed at a 1-for-2 ratio to Honeywell Technologies shareowners of record as of June 15, 2026. The newly independent aerospace supplier commenced trading on the Nasdaq Stock Market under the ticker symbol “HONA,” while the legacy automation business continues to trade under the “HON” ticker.

Strategic shift to pure-play automation

The corporate restructuring effort was initiated in 2023. Honeywell communicated its intention to spin off its advanced materials business in October 2024, followed by the February 2025 announcement detailing the separation of its automation and aerospace divisions. The board of directors formally set the record date and expected timing for the final spin-off on June 5, 2026.

Vimal Kapur, chairman and chief executive officer of Honeywell Technologies, described the completion as a defining moment for the company.

“With the completion of this separation, we have successfully transformed Honeywell into three independent, industry-leading companies: Honeywell Technologies, Honeywell Aerospace and Solstice Advanced Materials. Each company is built around a distinct strategy with greater focus and financial flexibility to pursue a long-term growth agenda,” Kapur stated in the press release.

To reflect its new operational focus on the building, industrial, and process sectors, Honeywell Technologies will file a Current Report on Form 8-K with the U.S. Securities and Exchange Commission. According to StreetInsider, this filing will present the former aerospace and advanced materials businesses as discontinued operations and provide recast historical financial data for fiscal years 2024, 2025, and the first quarter of 2026.

The dissolution of the Honeywell conglomerate reflects a broader aerospace and industrial sector trend favoring specialized, pure-play operations over diversified holding companies. By isolating the aerospace division, Honeywell Aerospace can now pursue targeted capital allocation and mergers and acquisitions specific to aviation manufacturing and supply chain demands. For the legacy automation business, shedding the capital-intensive aerospace unit provides a clearer value proposition for investors focused on industrial technology and building automation. We expect the newly independent aerospace entity to face immediate scrutiny regarding its supply-chain resilience and production ramp-up capabilities as it operates without the financial buffer previously provided by the broader conglomerate.

SeAH Besteel Holdings is accelerating its transition into the advanced aerospace materials sector with the upcoming completion of a new nickel-based superalloy manufacturing facility in Temple, Texas. Announced in a June 24, 2026 press release, the production hub operated by U.S. subsidiary SeAH Superalloy Technologies is scheduled to begin operations in the second half of 2026.

The facility represents a strategic pivot for South Korea’s largest special steelmaker to establish a localized supply chain for North American aerospace and defense manufacturers. By positioning production within the Central Texas advanced manufacturing corridor, the company aims to capitalize on industry-wide reshoring initiatives.

Facility specifications and production capabilities

The 45-acre Temple facility will have an annual production capacity of 6,000 tons of specialty materials. Production will focus on master alloys, additive manufacturing (AM) powders, and nickel-based superalloys required for high-stress aerospace applications.

The project stems from a $155.3 million total investment approved by the SeAH Besteel Holdings board in May 2024. The Office of the Texas Governor subsequently announced the facility agreement in July 2024, noting an estimated initial construction cost of $110 million.

Recent hiring activity indicates the plant is nearing operational readiness. According to reporting by BusinessKorea, SeAH Superalloy Technologies completed recruitment for core technical personnel in May 2026. The hiring of metal chemists responsible for alloy composition analysis signaled that the facility’s melting furnace had entered the trial-run stage. SeAH Superalloy Technologies Chief Executive Officer Michael King stated the project remains “on track, on time, and under budget.”

Expanding North American aerospace integration

The Texas hub builds upon the company’s existing footprint in the commercial aviation supply chain. SeAH currently holds aerospace certifications from The Boeing Company, Airbus SE, and Lockheed Martin Corporation.

In December 2025, subsidiary SeAH Aerospace & Defense secured a Long-Term Agreement (LTA) with Boeing to supply high-strength aluminum alloy materials for aircraft fuselages and wings starting in 2026. The localized production capability in Texas is designed to support similar direct-supply pipelines for Original Equipment Manufacturers (OEMs).

A representative for the parent company noted in the press release that the organization is “transcending its identity as a traditional special steelmaker to leap forward as an advanced materials platform driving the future of the global aerospace industry.”

We view SeAH’s physical expansion into Central Texas as a calculated response to the aerospace industry’s broader push for supply chain resilience. OEMs are increasingly prioritizing localized material sourcing to mitigate the logistical vulnerabilities exposed over the past five years.

While SeAH has not officially confirmed contract volumes with specific commercial space operators in its corporate releases, industry analysts widely anticipate the company will supply specialty alloys to major U.S. space entities like SpaceX. The demand for materials capable of withstanding extreme temperatures in orbital and suborbital applications aligns directly with the capabilities of the new Temple facility. Establishing a domestic U.S. footprint is often a prerequisite for securing sensitive defense and space contracts, positioning SeAH to compete directly with established North American alloy producers.
