Summary: The commenter supports Greiner PURtec's petition for an exemption from vertical burn requirements for cushion assemblies. They argue that the exemption is necessary to prevent financial hardship during a transition to water-based adhesives and that the safety of the flying public is not compromised.
To the Federal Aviation Administration,
I am writing to express my strong support for Greiner PURtec's petition for an exemption from the vertical burn requirements of 14 CFR 25.853(a) and 14 CFR 21.601(b)(2) for TSO-C72() cushion assemblies. Greiner PURtec's proactive shift to a water-based adhesive demonstrates a commitment to environmental and human health, aligning with public interest. The temporary exemption is crucial for continued production, preventing significant financial hardship for Greiner PURtec, its employees, and its customers, while the company actively pursues a fully compliant alternative. The safety of the flying public is demonstrably not compromised, as evidenced by the equivalent or improved performance in oil burn testing compared to previous solvent-based adhesives. Granting this exemption would facilitate a responsible transition to environmentally friendlier materials without disrupting vital industry operations.
