The FAA has issued an update to its 2010-2011 Ground Deicing Holdover Time Tables and Guidance on its website. The document contains a revised listing of the lowest operational use temperatures (Lout) for anti-icing fluids, which were supplied to the agency and Transport Canada by the fluid manufacturers.
Improper de-icing procedures led to an accident that substantially damaged a Flexjet Challenger 300 last winter at Chicago Executive Airport, according to the NTSB. The Safety Board concluded that the operator of the de-icing vehicle did not adhere to company procedures and did not maintain clearance between the vehicle’s boom and the airplane during the de-icing operation.
FedEx Express is converting its entire fleet of 250 Cessna 208 Caravans from de-icer boots to CAV Aerospace TKS ice-protection systems and Garmin G600
Cavu Companies has added a new hold-over time (Hot) module to its EFB-Pro performance software to help pilots ensure compliance with regulatory re quirements for ground anti-icing/de-icing fluid application and pre-takeoff icing checks. The Hot module costs $250 for the first year and $100 for annual renewal. Current EFB-Pro subscribers can upgrade for the $100 renewal price.
Bombardier BD-100-1A10, Wheeling, Ill., Feb. 24, 2010–The Challenger 300 was substantially damaged when it was struck by a de-icing vehicle while preparing for departure for a Part 91 flight from Chicago Executive Airport. Marginal VMC existed at the time of the accident. Neither pilot on board was injured.
The FAA issued a safety alert for operators (Safo 01001) warning operators of aircraft with unpowered elevator controls that control forces may increase after application of Type II or IV anti-icing fluids. The Safo is the result of reports to the FAA of rejected takeoffs due to above-normal control pressure needed to achieve rotation. These rejected takeoffs were initiated at speeds above Vr or V1, according to the FAA.
At a February 24 hearing on aircraft icing legislators criticized the FAA for delaying implementation of rulemaking that would address outstanding issues on the NTSB’s “Most Wanted” list. “After the Colgan Air Flight 3407 accident near Buffalo last year,” said committee chairman James Oberstar (D-Minn.), “it was widely speculated that the aircraft crashed due to icing.
The American Association of Airport Executives (AAAE) and National Air Transportation Association (NATA) both recently submitted comments to the Environmental Protection Agency (EPA) on proposed new rules for limiting de-icing fluid runoff at commercial airports. The EPA proposal would establish standards for the amount of aircraft de-icing fluid that airports must recapture and prevent from entering wastewater runoff.
The House aviation subcommittee yesterday held a hearing on aircraft icing to address issues brought to light by the NTSB’s recent “Most Wanted” list of “unacceptably slow” progress on icing rulemaking.
Hawker Beechcraft C99, Kearney, Neb., Jan. 6, 2010–The turboprop twin, operating under Part 135, was substantially damaged during a hard landing in IMC at Kearney Municipal Airport. The pilot reported that he cycled the de-icing boots before the final approach fix after noting light to moderate icing.
