This thesis investigates crashworthiness in small aircraft, identifying significant gaps in safety standards compared to commercial aviation. Due to their lightweight design and limited cabin space, small planes are highly vulnerable during crashes. Experimental tests compared traditional aluminum alloys with advanced composites like carbon fiber and aramid, demonstrating superior impact absorption and cabin protection from the latter. Structural reinforcements such as crushable zones and reinforced fuselages improved survivability. Additionally, energy-absorbing seats combined with advanced restraint systems significantly reduced forces on occupants. Based on these findings, the study recommends adopting composites, structural reinforcements, and enhanced seating systems as standard in small aircraft design, along with updates to crashworthiness regulations.
