ATA 2140

Part: DUCT — RUPTURED · airframe 34 hrs

AT 1920, THERE WAS A NOISE, WHICH SOUNDED LIKE A (POP) AND A SLIGHT ODOR OF SOMETHING GETTING HOT. IT SHOULD BE NOTED HERE THAT THE CABIN HEAT WAS ON HIGH, AND HAVE SMELLED SMELLS LIKE THAT BEFORE. IN OTHER WORDS, THE ODOR WAS NOT ENTIRELY UNCOMMON. LOOKED OVER LT SHOULDER OUT THE LT SLIDING DOOR WINDOW. SAW LIGHTS ON THE HORIZON, BUT IT APPEARED AS IF SEEING THEM THROUGH SMOKE. THIS, OF COURSE, GOT IMMEDIATE ATTENTION AND WAS THE REASON FOR THE PRECAUTIONARY LANDING. AT THAT POINT, THOUGHT THERE WAS A FIRE IN THE ENGINE OR TRANSMISSION, ALTHOUGH THERE WERE NO OTHER INDICATIONS OF FIRE.
