Which of the following is a limitation to sling load operations?

• A. Surface Conditions
• B. Airframe corrosion
• C. Extended service life
• D. Noise complaints

Answer: (B)

Airframe corrosion directly compromises the strength and integrity of the load-bearing structure. Sling loads put dynamic, shock-like stresses on the airframe, especially at attachment points and load paths. If corrosion is present, it can thin material, create pits and cracks, and hide hidden damage, all of which reduce fatigue life and safety margins. In these conditions a lift could exceed the weakened capacity, risking structural failure during flight. That direct impact on safety is why airframe corrosion is the limiting factor for sling load operations.

Surface conditions affect ground handling and the immediate environment but don’t inherently limit the aircraft’s ability to carry a sling load in flight. Extended service life and noise complaints relate more to maintenance scheduling or community relations than to the immediate operational safety of a lift.
