Which substance should be used to preserve arresting gear, landing gear, wing fold tail skid, and exposed portions of reciprocating rods?

Which substance should be used to preserve arresting gear, landing gear, wing fold tail skid, and exposed portions of reciprocating rods?

• A. Mil-PRF-83282 hydraulic fluid
• B. Mil-PRF-83282 additive
• C. MIL-PRF-6081
• D. Water

Answer: (A)

Protecting exposed metal surfaces on aircraft components requires a corrosion-preventive film that is approved for use on those parts and compatible with the materials involved. Mil-PRF-83282 hydraulic fluid is specified for this purpose because it provides a protective, film-forming layer that displaces moisture and inhibits rust on unpainted or exposed surfaces such as arresting gear, landing gear, wing fold tail skid, and exposed portions of reciprocating rods. This fluid is designed for storage and maintenance environments, offering both lubrication and corrosion protection without harming the metals or rubber seals common in these assemblies. Using the additive alone wouldn’t give you the full protective film and broad compatibility needed for these surfaces. Water is not a preservative here and would promote corrosion. MIL-PRF-6081 is a hydraulic fluid intended for normal system operation, not specifically for long-term exterior corrosion protection of these exposed components.
