Polycast UV-SC is the latest addition that Spartech has made to its growing product line of structural transparencies targeting the aircraft, mass transit, automobile and architectural markets. Polycast embodies the technology to produce cast acrylic sheet in a variety of colors that block significant amounts of ultraviolet (UV) light and the near-infrared solar energy’s heat radiation while maintaining high visible light transmission.

Kestrel Aircraft has tapped Cox to supply an electro-mechanical ice protection system for its single-engine turboprop, the companies announced today at the NBAA Convention. The system allows “effective ice removal” without the need for de-icing boots or an anti-icing fluid system. According to Kestrel president and CEO Alan Klapmeier, the electro-mechanical system “allows for effective ice removal while retaining a laminar flow.” The single-engine Kestrel is expected to be in service by 2016.

Timco Aerosystems’ new dynamic sled test facility in Wallburg, N.C., has received FAA approval for the testing of aircraft seats to show compliance with regulatory codes 14CFR25.562 and 14CFR23.562. The approval enables Timco to test seats for compliance with critical occupant safety impact standards, including 16-g horizontal and 14-g vertical structural thresholds.

A contingent of U.S. Air Force flight attendants participated in this year’s NBAA Flight Attendants/Flight Technicians conference, not just to learn from their peers but to share their own experiences using dry ice as a cooling medium to keep food safe on long trips. It turns out that a sufficient quantity of dry ice allows for weeks of operation and proper food storage. There are important safety considerations when using dry ice.

The FAA yesterday issued Draft Advisory Circular 20-147A, which provides new guidance to aircraft manufacturers on compliance with regulations covering engine induction system icing and engine installation ice requirements. The new guidance will replace AC20-147A, which was last revised in 2004. Comments on the draft AC are due by November 1 and can be sent to the FAA's John Fisher.

Proposed changes to Parts 25 and 33 address dangerous icing conditions caused by supercooled large drops including a requirement that manufacturers not only show that airplanes can operate safely in those conditions but also with specific performance and handling qualities and that “all new transport-category designs be able to fly in co

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.

Pilots should “activate boots as soon as the airplane enters icing conditions,” according to a safety alert released in December by the NTSB. The alert (SA-014) is yet another attempt by the Board to persuade pilots that there is no such thing as ice bridging and that pilots should not wait for ice to build to one-quarter to one-half-inch thickness before inflating boots in icing conditions.
