This report presents the results of three recent test series conducted to investigate the response of aircraft structures and flight controls to attack by small-arm and small-arm incendiary fire. The first test series explored the response of nearly empty fuel cells when impacted in the ullage region by armor-piercing incendiary gunfire. The second was designed to determine the response of full fuel tanks to the hydraulic ram phenomenon when subjected to small-arm fire. The third examined the damage to pressurized hydraulic lines and subsequent ignition of hydraulic fluid when subjected to small-arm incendiary fire. Author
