Narrative:

At FL360 2.2 hours into the flight we observed thick smoke evacuating the environment ducting into the flight deck and passenger area. Both crew members immediately donned O2 masks. Smoke goggles were supplied but the smoke penetrated the goggles and the oil the smoke carried created a film on the goggles which hindered vision. The goggles were removed during the descent and shortly after the smoke was evacuated through checklist procedure. The right engine was secured after it was determined oil pressure loss; prior to the descent. Smoke goggles do not work in this type of emergency. It should be mandated that a full face shield/O2 system be placed in 135 aircraft. Similar to firefighters apparatus. Callback conversation with reporter revealed the following information: engine was a garrett tfe-731 which experienced a carbon seal failure that allowed oil spray and fumes into the bleed air system. The reporter felt that a one piece smoke mask could have prevented the oil film and fogging that occurred with the installed smoke goggle system.

Title: PLT OF IAI 1124 RPTS THAT COCKPIT SMOKE GOGGLES DO NOT PROVIDE ADEQUATE PROTECTION DURING SMOKE EVENT CAUSED BY ENGINE OIL INGESTION INTO THE AIR CONDITIONING/PRESSURIZATION SYSTEM.

Narrative: AT FL360 2.2 HRS INTO THE FLT WE OBSERVED THICK SMOKE EVACUATING THE ENVIRONMENT DUCTING INTO THE FLT DECK AND PAX AREA. BOTH CREW MEMBERS IMMEDIATELY DONNED O2 MASKS. SMOKE GOGGLES WERE SUPPLIED BUT THE SMOKE PENETRATED THE GOGGLES AND THE OIL THE SMOKE CARRIED CREATED A FILM ON THE GOGGLES WHICH HINDERED VISION. THE GOGGLES WERE REMOVED DURING THE DSCNT AND SHORTLY AFTER THE SMOKE WAS EVACUATED THROUGH CHKLIST PROC. THE R ENGINE WAS SECURED AFTER IT WAS DETERMINED OIL PRESSURE LOSS; PRIOR TO THE DSCNT. SMOKE GOGGLES DO NOT WORK IN THIS TYPE OF EMER. IT SHOULD BE MANDATED THAT A FULL FACE SHIELD/O2 SYSTEM BE PLACED IN 135 ACFT. SIMILAR TO FIREFIGHTERS APPARATUS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ENG WAS A GARRETT TFE-731 WHICH EXPERIENCED A CARBON SEAL FAILURE THAT ALLOWED OIL SPRAY AND FUMES INTO THE BLEED AIR SYSTEM. THE RPTR FELT THAT A ONE PIECE SMOKE MASK COULD HAVE PREVENTED THE OIL FILM AND FOGGING THAT OCCURRED WITH THE INSTALLED SMOKE GOGGLE SYSTEM.
