Each oil tank must be designed and installed so that—
It can withstand, without failure, any vibration, inertia, and fluid loads to which it may be subjected in operation; and
It meets the requirements of § 29.965, except that instead of the pressure specified in § 29.965(b)—
For pressurized tanks used with a turbine engine, the test pressure may not be less than 5 p.s.i. plus the maximum operating pressure of the tank; and
For all other tanks, the test pressure may not be less than 5 p.s.i.
