What is the stripping frequency for JP-5 service tanks at sea?

• A. Daily
• B. Weekly
• C. Monthly
• D. Quarterly

Answer: (A)

Maintaining clean JP-5 in service tanks hinges on regularly purging water, sediment, and degraded fuel before it flows into aircraft systems. At sea, condensation, movement, and exposure to the marine environment raise the chance of water contamination and particulate buildup, so stripping daily removes contaminants promptly and keeps fuel within required specs for immediate flight operations. If the interval were longer, water could separate and settle and sediments could accumulate, increasing the risk of clogged filters, corrosion, or fuel-system issues. Less frequent stripping would not control contamination quickly enough during underway operations, whereas longer intervals would let fuel quality deteriorate. Daily stripping therefore ensures readiness and safety while at sea.
