AMP - Aviation Maintenance Technician Powerplant Practice Exam

After installing a new fixed pitch wood propeller, it is important to inspect the bolts for proper torque since they can loosen during the first few hours of flight. Option A is incorrect because a proper torque check is needed more often during the initial break-in period, not just after the annual inspection. Option B is incorrect because bolts can still loosen over time and must be inspected periodically. Option D is incorrect because even if the propeller appears to be in good condition, the bolts can still loosen and cause safety hazards. Therefore, option C is the best choice, as it ensures proper torque is maintained after the initial break-in period, which can help prevent accidents due to bolt failure.
