Large area avalanche photo diodes (APD), a new and very promising type of light detector, were tested at high gain on a beam line and suddenly failed. A detailed study of the failure modes showed that these devices, if used at low gain and with special care, may actually be used in high-energy physics environments and indicates the road of development toward radiation hard, large area APDs. No problem was found when APDs are operated in absence of highly ionizing particles.
