JP-5 storage tank stripping at sea must occur prior to which events?

• A. refueling
• B. transfer to service
• C. both refueling and transfer to service
• D. neither

Answer: (C)

Tank stripping at sea is done to remove any remaining fuel, water, and contaminants so the next operation starts with a clean system. This is essential before refueling because residuals from the previous load can contaminate the new JP-5 being loaded, risking fuel quality and damaging aircraft fuel systems and filters. It’s also required before transferring to service to ensure that the service tanks and distribution lines carry only the intended product, meeting cleanliness specifications and avoiding cross-contamination. If stripping isn’t done, contaminants or moisture from prior contents can cause engine performance problems, clogged filters, or corrosion-related issues in the fuel system. For both fueling and transfer to service, starting with a clean tank helps maintain fuel integrity and system safety, so stripping is performed prior to these events.
