Which signs indicate structural instability after an aircraft crash?

• A. Smoke color and intensity indicators.
• B. Engine temperature readings.
• C. Distorted fuselage, bending wings, sagging landing gear, cracking or spalling surfaces.
• D. Weather conditions and wind direction.

Answer: (C)

After a crash, you assess the airframe for signs that its load-bearing structure may be compromised. Distorted fuselage indicates the main body has buckled and stretched beyond its designed shape, meaning the structural integrity is reduced. Bending wings show the wings have lost rigidity and could fail or warp under loads, increasing the risk of sudden structural collapse. Sagging landing gear means the support system has yielded and may drop further or fail, creating an unstable platform. Cracking or spalling surfaces reveal fractures or material pieces breaking away, signaling progressive damage in the structural skin and internal members. These signs collectively point to a high risk of further collapse or sudden failure, so treat the area as structurally unstable and keep clear until responders declare it safe. Smoke color and intensity relate to fire conditions rather than structural health, engine temperature readings aren’t reliable indicators of post-crash structural integrity, and weather conditions don’t reflect the airframe’s current stability.
