What is the maximum recommended torque?

• A. 44.34 PSI
• B. 44.84 PSI
• C. 40.63 PSI
• D. 46.00 PSI

Answer: (A)

Torque is the turning force used to tighten a fastener to a precise limit, and those limits are given in units of torque (ft-lbs or N-m), not in pressure. PSI measures pressure, such as system or hydraulic pressure, and has no direct bearing on how tightly a bolt should be torqued. So a question asking for the maximum recommended torque should point to a numeric value in torque units found in the aircraft’s maintenance manual, not a pressure value.

To answer correctly in real life, you’d look up the exact torque specification for the component in the manual or placard, taking into account bolt size, lubrication, and condition. Apply that torque with a calibrated torque wrench, following the prescribed tightening sequence, and recheck as required by the maintenance data.

The mismatch here—torque asked for but options given in PSI—means none of the pressure values serve as a proper torque specification. The key takeaway is to always use the specified torque value in ft-lbs or N-m from the manual rather than any pressure reading.
