Narrative:
May/tue/96, installed turbo charger and torqued holding clamp. Apparently the v-clamp went on only 1/2 of the assembly, causing blow-by and heat damage to the front gear well and other structures. The clamp is well hidden and hard to inspect. Suggest that after installation of the clamp, the aircraft be run and the clamp retorqued and inspected with a mirror.
