Acro Aircraft Seating Certifies Tiderock-Manufactured Composite Seat Backs for Boeing 737 and Airbus A320 Applications;
Milestone Advances Parent Company Tiderock Companies, Inc. (OTC:TDRK) Aviation Strategy
BOSTON, MA AND CONINGSBY, LINCOLNSHIRE, UK / ACCESS Newswire / April 27, 2026 / Tiderock Composites Ltd, a subsidiary of Tiderock Companies, Inc. (OTC:TDRK), today announced that longstanding aviation partner Acro Aircraft Seating has certified Tiderock-manufactured composite seat back components in accordance with FAR 25.853 / CS 25.853, the mandatory flammability standard governing cabin interior components on all commercial transport aircraft. The certification covers the latest generation of seat back assemblies produced at Tiderock Composites’ Coningsby, Lincolnshire facility, with components intended for use in applications including Boeing 737 and Airbus A320 family aircraft.
FAR 25.853 (administered by the U.S. Federal Aviation Administration) and its European equivalent CS 25.853 (administered by EASA) establish the global standard for fire safety of cabin interior materials aboard commercial aircraft. For seat back components, certification requires demonstrating self-extinguishing properties, strict limits on burn length and flame propagation, and resistance to flaming drip – each designed to ensure passengers have the maximum possible time to evacuate in the event of an in-flight fire. The two standards are substantively identical and are recognized across all major aviation regulatory regimes worldwide.
Tiderock Composites has manufactured seat back components installed across both Boeing and Airbus aircraft platforms, reflecting decades of accumulated expertise in aviation-grade glass-reinforced polymer (GRP) and composite fabrication. The Acro certification of this latest component generation builds directly upon that heritage and strengthens Tiderock Composites’ position as a qualified supplier to the commercial aviation interiors market.
“This certification is a defining milestone for Tiderock Composites and a testament to the depth of our partnership with Acro Aircraft Seating. Our seat backs have flown on Boeing and Airbus aircraft for decades – achieving this qualification on our latest components ensures we are positioned to continue serving the aviation industry for decades to come, at the highest standards the market demands.”
– Will Waldrop, CEO, Tiderock Companies, Inc. (OTC:TDRK)
This flammability certification establishes a strong foundation for Tiderock Composites to pursue expanded opportunities within the aviation interiors sector. The company’s Coningsby manufacturing facility is equipped for hand lay-up and resin transfer moulding (RTM) production processes suited to aircraft interior components, and management intends to leverage this certification as a platform credential in engagement with additional Tier 1 aerospace primes and OEM supply chains.
This development reinforces Tiderock’s position as a technically credentialed composites manufacturer serving mission-critical aerospace applications and supports the company’s broader strategy of deepening its presence across the commercial aviation supply chain. Management views the Acro certification as an anchor reference point in ongoing commercial development efforts within the sector.
