Responding to new Environmental Protection Agency guidelines that could eventually become law, Octagon Process has developed a Type 1 de-icer fluid that uses less propylene glycol than typical fluids. According to Octagon president Joe McGrail, when propylene glycol gets into wetlands, it breaks down and microorganisms form and attack the glycol.
The FAA recently issued a revised Special Airworthiness Information Bulletin–SAIB SW-08-03R1–to warn helicopter operators of the “hazards of snow and ice,” according to the FAA Rotorcraft Directorate’s Safety Management Group in Fort Worth. The bulletin, “Recommendations for Rotorcraft During Icing Conditions,” was released in 2003, and new data has been added following additional FAA testing.
The FAA has issued a final rule that prohibits Part 91K, 135 and 121 operators from taking off with “polished frost”–meaning frost buffed to make it smooth–on an aircraft’s wings, stabilizers and control surfaces. The new rule takes effect at the end of this month. Previous FAA guidance recommended removing all wing frost before takeoff, but allowed it to be polished smooth if the aircraft manufacturer’s recommended procedures were followed.
The FAA yesterday issued a final rule that prohibits Part 91K, 135 and 121 operators from taking off with “polished frost”–meaning frost buffed to make it smooth–on an aircraft’s wings, stabilizers and control surfaces. The new rule will take effect on Jan. 30, 2010. The FAA already prohibits major and regional air carriers from operating with polished frost.
Coincidental to the early taste of winter weather the Northeast received in mid-October, NBAA–in conjunction with local airport user groups and state business aviation associations–sponsored a pair of cold-weather operational seminars aimed at exploring the challenges and threats presented by in-flight and ground icing, as well as runway contamination.
One of the founders and innovators of the TKS anti-icing system plans to launch the world’s first environmentally friendly anti-icing fluid called TKS Sustain, based on propane diol rather than the more traditional ethylene glycol. Kilfrost, exhibiting here at Booth No. 5513, has submitted the product for certification and expects to gain approval to market it this coming winter.
The National Air Transportation Association (NATA) has joined with other aviation associations to ask the Environmental Protection Agency (EPA) for a 60-day extension on the comment period for new proposed rules on airport de-icing fluid effluent limitations. The timing of the initial rules proposal falls within the traditional northern-hemisphere de-icing season.
The FAA last month amended its certification standards for icing protection on transport-category airplanes. The new rule, which goes into effect September 2, will require new systems to increase pilot situational awareness during icing conditions.

The crash of a Régional Fokker 100 shortly after takeoff from Pau, southwest France, in January 2007 was caused by undetected ground ice and excessive rotation on liftoff, according to the French air accident investigation board. The accident killed one driver on the road the aircraft traversed.
