The MIL-PRF-38299E specification outlines the requirements for a purging fluid designed to preserve fuel tanks in jet aircraft before maintenance activities. It replaces the earlier specification MIL-PRF-38299D and establishes that the purging fluid must consist entirely of hydrocarbon compounds, allowing for the use of both virgin and recycled materials. The document details the necessary chemical and physical properties of the fluid, including requirements on distillation, specific gravity, total sulfur content, and electrical conductivity, alongside relevant ASTM test methods.
Additionally, the specification mandates the inclusion of antioxidants to prevent the formation of harmful substances, as well as additives to enhance electrical conductivity. The fluid must be safe for personnel and free from contaminants. The specification also outlines inspection protocols, ensuring compliance with the necessary quality standards, including sampling methods and potential grounds for rejection of the product.
Aimed at all Department of Defense agencies, the specification serves as a fundamental resource for procurement and quality assurance, ensuring the functionality and safety of aircraft maintenance operations by providing a clear framework for the purging fluid's characteristics and testing methods.
The 309 Aircraft Maintenance Group issued a specification for the delivery of 22,500 gallons of Purge Fluid compliant with Mil-Spec MIL-PRF-38299E. The fluid must arrive in a semi-tanker trailer without the need for recycling. Delivery requires specific equipment for off-loading, including compatible fittings and hoses, or an alternative pumping method if the on-site system is inactive. Key acquisition requirements include a Certificate of Conformance, Bill of Lading, and Safety Data Sheet. Deliveries must occur at designated locations within Hill Air Force Base, Utah, within three weeks post-award, adhering to strict scheduling rules: only one truck delivery per day, with a minimum interval of 24 hours. The driver is required to have a valid driver’s license, English proficiency, and pass a security check, with prior communication to arrange base access. This document outlines the procurement needs and logistical requirements for acquiring essential operational supplies for the 309 AMXG, showcasing compliance with military standards and local procedural regulations.
