Which statement best describes the impact of not following OEM and Navy manuals during maintenance?

• A. Increased safety and reliability.
• B. They are optional and can be ignored to save time.
• C. No impact on safety or reliability.
• D. Only affects documentation.

Answer: (D)

Not following OEM and Navy manuals during maintenance removes the validated guidance that ensures equipment is repaired to exact, tested standards. Those manuals specify how to perform each step, what torque values to use, what clearances are acceptable, what inspections to run, how to lubricate, and what safety checks must be completed. Skipping or deviating from them can lead to improper assembly, under- or over-torqued fasteners, missed wear or crack indications, inadequate lubrication, and incorrect reassembly—all of which directly threaten safety and reliability during operations.

So the impact isn’t limited to paperwork. While documentation is important, the real risk is that safety and performance of the equipment can be compromised, reducing mission readiness and potentially creating hazardous conditions. The other statements miss that broader, safety-critical effect.
