What could be a possible drawback of having a family or friend use your aircraft?

The concern regarding having a family member or friend use your aircraft relates directly to the potential for damage or changes to its condition. When someone who is not the owner operates the aircraft, there is a legitimate risk that they may not handle the aircraft with the same care or attention as an experienced pilot or the owner themselves might. This negligence could lead to wear and tear, cosmetic damage, or even mechanical issues that could necessitate repairs.

While the other options touch on valid concerns—such as familiarity with the aircraft and not having legal paperwork—the primary and most immediate concern for many aircraft owners is ensuring the aircraft's condition is maintained. It is critical for owners to protect their asset, and allowing others to use it could lead to unforeseen expenses and headaches if the aircraft returns with issues that need addressing.
