Loose fabric affects the __________ distribution and __________ the airframe.

The correct answer focuses on the impact of loose fabric on the structural integrity and performance of the airframe. When fabric is not properly tensioned, it can affect the weight distribution over the aircraft's surface. An uneven weight distribution can lead to imbalances during flight, creating irregular stresses on the airframe, which can compromise overall safety and performance.

Additionally, the fabric's looseness can lead to increased aerodynamic drag, further exacerbating stress on the aircraft as it flies. Properly tensioned fabric is crucial as it helps to ensure an even load distribution, which significantly contributes to the structural integrity and performance of the aircraft. This understanding is essential for anyone involved in the maintenance and inspection of aircraft fabric coverings.
