A proposed AD would require the installation of deicing boots on the landing-gear struts of nearly 750 U.S.-registered Cessna 208 Caravans, as well as other changes to deicing equipment and procedures contained in a 1991 Cessna accessory kit. The directive stems from the FAA’s investigation into nine incidents within the past few months and six accidents in the previous two icing seasons.
An FAA draft letter of interpretation seeks public comment by May 3 on the meaning of the term “known icing conditions,” used–but undefined–in the FARs.
Back in the early 1930s, when Capt. Elrey Jeppesen first started delivering airmail to remote towns and cities in the Western U.S. in single-engine Boeing biplanes, aviation most assuredly leaned more toward art than science.
A Raytheon Premier I that ran off the runway on landing at North Las Vegas Airport (VGT) on May 27 might have gotten caught in a wind shift from a crosswind to a quartering tailwind moments before touching down. There were no injuries to the pilot or passenger, but the aircraft was substantially damaged, according to the NTSB’s preliminary report. The airplane touched down on 5,004-foot-long Runway 7 at 3:57 p.m.
Banking and oil heir Michael Huffington, who is suing Bombardier over a Global Express he first ordered in 1995 and later rejected after he learned the aircraft had been struck by lightning, has produced a consultant’s report hoping to bolster his lawsuit against Bombardier. That report claims that the GEX is far more likely to be hit by lightning and suffer serious damage than its competitors. Bombardier disputes the report.
Taylor Madison Corp. is the new name for the former Nimbus Group, the cosmetics and perfume company that until early last year maintained its intention of buying 1,000 Eclipse very light jets to establish a nationwide air-taxi service under a subsidiary called Nimbus Jets. The new company will dispose of the Nimbus Jets trademarks, trade names and Web-site domain name.
Predicting the weather is a little like trying to pick up Jell-O before it sets. There are a lot of molecules up there, all interacting in less than predictable ways. It is a little surprising, then, that the head of one of the world’s foremost weather-data specialists says forecast accuracy is about to see vast improvements over and above what today’s computer modeling is capable of generating.
Bombardier CL-600-2B19, Rapid City, S.D., Jan. 17, 2004–The NTSB determined that the left wingtip of the Skywest CRJ hit the runway because of the copilot’s failure to maintain control and the captain’s delay in initiating remedial action. Factors contributing to the accident were the low ceiling and low visibility due to fog, and the aircraft’s deviation from expected performance because of airframe icing.
Using a new Web-based tool, operators who typically fly below Class A airspace can now obtain icing forecasts up to 12 hours in advance of their flight. The FAA tool provides a color weather map and a flight route display of icing potential from 3,000 to 18,000 feet. The user can select forecast times from three-, six-, nine-, and 12-hour intervals to help plan their routes.
A new NASA study claims that man-made cirrus clouds formed by commercial jet engine exhaust might be responsible for increased surface temperatures detected in the U.S. between 1975 and 1994.
Climate data shows that cirrus cloud cover over the U.S. has increased by 1 percent per decade, and the report says the rise is likely due to commercial air traffic.
