FAA The Recreational UAS Safety Test (TRUST) Practice Test

Regular preflight and postflight checks are essential because damage can be present or develop during handling, takeoffs, landings, or transport, and catching it early keeps the drone safe to fly. Before flying, you look for loose or damaged propellers, check battery connections, verify controls respond correctly, and ensure the airframe is intact. After flying, you inspect for cracks, bent props, loose parts, signs of motor wear, and battery swelling. Finding issues at these times lets you repair or replace components before the next flight, reducing the risk of in-flight failure. This is why the statement is true.
