FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

When the right wing is improperly rigged to a greater angle of incidence compared to the left wing, it can result in the airplane being off balance both laterally (side to side) and directionally (yawing). This misalignment can cause the aircraft to have uneven lift and drag on each wing, leading to lateral imbalances during flight. Furthermore, the directional stability of the aircraft can also be compromised due to the uneven lift distribution, causing the airplane to yaw and potentially affect its overall stability. Therefore, the correct answer is that improper rigging of the right wing to a greater angle of incidence results in the airplane being off balance both laterally and directionally.
