Cessna 208B Caravan, Parks, Ariz., Nov. 8, 2002–The NTSB attributed the Caravan accident to the pilot’s improper in-flight planning/decision making, his flight into known icing conditions and his failure to maintain adequate airspeed. Factors were the pilot’s improper preflight planning/preparation, the icing conditions and an inadvertent stall and spin.
The recently issued FAA Notice JO 7110.616 “adds the detection of sulfur gases (H2S and SO2) in the aircraft cabin,” to questions briefers might ask pilots when soliciting for Pireps. H2S, also known as sewer gas, has the odor of rotten eggs, while SO2 is identifiable as the sharp, acrid odor of a freshly struck match. The FAA plans to report volcanic activity when pilots do not see an ash cloud but do smell sulfur gases within the cockpit and or cabin.
