Founded in Wichita by Dr. A.H. Renforth and W.G. Dalloway, RDFIA has remained an independent testing laboratory through four decades of aerospace consolidation. We have never operated as a captive subsidiary of a prime contractor.
Dr. Arthur H. Renforth (formerly of the Midwest Aeronautical Structures Laboratory) and Wallace G. Dalloway (formerly of Cessna Aircraft's structures group) establish Renforth-Dalloway Testing Associates in a 4,800 sq ft leased facility on the west side of Wichita. Initial equipment comprises two 400 kN servo-hydraulic frames, an MTS 810 controller, and a Nicolet data recorder. First contract: coupon fatigue characterisation for an undisclosed turboprop airframe OEM.
Following the inaugural publication of the Joint Aerospace Structural Fatigue Standard (JASF-9) by the Aeronautical Structures Oversight Consortium (ASOC), RDFIA is among the first 11 independent laboratories to achieve JASF-9 designation. The designation requires demonstrated proficiency in spectrum load simulation and independent data traceability — criteria that remain central to RDFIA's operating model.
RDFIA opens its second facility in Palmdale, California, to support growing demand from Southern California aerospace primes. The Palmdale site is built around two large-frame servo-hydraulic systems and a dedicated coupon preparation laboratory. Wallace Dalloway retires; his son, Peter Dalloway, joins the firm as Director of Operations.
In response to increasing demand from launch vehicle programs, RDFIA constructs a blast-rated pressure cycling facility at a leased site in Huntsville, Alabama. The facility is designed from the outset to accommodate cryogenic propellant-compatible pressure vessels and receives DVST-7 clearance in 1999. Dr. Renforth delivers the inaugural Holvik Memorial Lecture at the ASOC annual symposium.
RDFIA establishes a wholly owned subsidiary, RDFIA Europe SAS, with laboratory operations adjacent to the Toulouse aerospace cluster. The facility supports European civil and defense programs requiring JASF-9 and EASA CS-25 compliant fatigue substantiation. RDFIA Europe holds independent ISO 17025 accreditation from COFRAC.
RDFIA internally develops and commercialises the FatigueLink™ data acquisition and cycle management platform, replacing third-party DAQ systems across all facilities. FatigueLink™ v4.3 currently supports 512-channel synchronous acquisition with real-time Rainflow counting, Veldtmann condensation scheduling, and automated regulatory hold logic.
Commissioning of RIG-7C in the newly constructed DVST-7 accredited secure bay at the Wichita headquarters. The frame supports classified structural fatigue programmes and is operated under a government technical representative oversight agreement. Dr. Renforth, now 81, remains non-executive Chairman of the Board.

Registered scope covers design, development, and provision of structural fatigue testing services for aerospace and defence applications. Surveillance audits conducted annually by IASQ-accredited registrar.
RDFIA holds Designated Laboratory status under JASF-9 Annexes I, II, III, and IV. Annex IV designation (cryogenic pressure vessel) applies to Huntsville facility only. Issued by the Aeronautical Structures Oversight Consortium.
Accredited for Nondestructive Testing (NDT), Materials Testing Laboratories (MTL), and Non-conventional Machining and Surface Enhancement (NMSE). Merit status achieved 2019.
Accreditation held by all four RDFIA facilities. US facilities accredited by A2LA (Certificate No. 4471.01); RDFIA Europe accredited by COFRAC (Portée No. 1-7842). Covers all mechanical testing and XRD measurement scopes.
Wichita headquarters holds DVST-7 facility clearance for the RIG-7C test bay. Personnel security requirements administered in conjunction with the cognizant government contracting authority. Programme details not publicly disclosed.
DHP-2 registration authorises RDFIA to issue DHP-conformant fatigue substantiation reports accepted by signatory prime contractors and government airworthiness authorities. Registration reviewed triennially by the DHP Oversight Board.
