I experienced a failure exactly like the one described in this proposed AD on Feb 26th of this year. The aircraft was a PA32R Turbo (1985 model year). We were in climb out from Camarillo airport (KCMA) and climbing through 1700 feet. We had been handed off to Center when we first smelt smoke and then an instant later the cockpit filled up with smoke. We declared an emergency, shut down electrical and made an emergency landing back at Camarillo on the opposite runway. After landing the mechanic found that the exhaust pipe elbow had detached from the turbocharger exhaust allowing hot gases to enter the cockpit which burnt through all the hoses and wiring. No obvious fracture or failure was visible in the flange. If this had happened a few minutes later into the flight, we would have been in IMC and over mountainous terrain. I strong recommend the AD be approved.
