Which tools are used to stabilize aircraft and prevent movement during rescue?

• A. Hammers and pry bars
• B. Power winches and straps
• C. Cribbing, airbags, heavy timber, jacks, and chocks prevent rolling, sliding, twisting, collapsing, or shifting.
• D. Foam concentrate and water hoses

Answer: (C)

Stabilizing the aircraft and preventing movement during rescue is about creating a rigid, secure support system that stops rolling, shifting, or collapse as rescuers work. The best set of tools for this is cribbing, airbags, heavy timber, jacks, and chocks. Cribbing blocks and heavy timber are placed under key points to distribute weight and prevent sinking or twisting, forming a solid foundation. Jacks allow controlled lifting and height adjustment to relieve concentrated loads and position the airframe for access, often used in conjunction with cribbing. Airbags spread the load and can lift or push against surfaces to close gaps and stabilize the structure where solid blocks can’t fit. Chocks lock wheels and prevent rolling, keeping the aircraft from moving if it settles or shifts due to uneven terrain or external forces. Together, these tools create a stable restraint system that keeps the aircraft steady so rescuers can work safely and effectively. Hammers and pry bars are for prying or forcing panels, which can introduce instability. Power winches and straps can move or reposition the aircraft if not carefully controlled, making stabilization unreliable. Foam concentrate and water hoses are for firefighting and cooling, not for keeping the aircraft from shifting during rescue.
