E-A-R Thermal Acoustics Systems (Stand 2145) is improving acoustic insulation aboard business jets as it endeavors to cut the most annoying cabin noises on a case-by-case basis.
The FAA last month approved upgraded flammability standards for thermal and acoustic insulation materials used in Part 25 (transport category) aircraft. Revised standards include new tests and criteria that address flame propagation and entry into the cabin of an external fire.
The FAA has issued clarifying bulletins, set up a team of specialists that can be contacted 24/7 and is considering amending its controversial rule upgrading flammability standards for thermal and acoustic fuselage insulation. The rule, which became effective September 2, poses a "serious threat to the continued operation of Part 25 [certified] aircraft," according to trade groups.
The FAA extended by 24 months–to Sept. 2, 2009–the date for affected regional and major airline operators to comply with new Part 25 fire safety requirements for thermal/acoustic insulation used in transport-category airplanes manufactured after September 2 this year.
New regulations regarding aircraft thermal and acoustic insulation have been amended in response to concerns raised by the business aviation industry that the requirements–effective Sept. 2, 2005-applied to a much broader range of components in in-service airplanes than was originally intended.
The National Air Transportation Association still has concerns regarding the recently published requirements for improved flammability characteristics of thermal/acoustic insulation used as replacements on aircraft manufactured before Sept. 2, 2005.
Qinetiq is here at the Paris Air Show with a new sunscreen for heat-sensitive aircraft. The UK-based research company has developed a new range of solar heat reflective coatings. The so-called low solar load (LSL) technology is aimed at reducing air-conditioning, insulation and heat-resistant materials needs.
For years, AccuFleet has been known for its flammability testing and certification of interior cabin components and cargo compartment materials, a “hot button” for the FAA. Now the Houston-based company has added thermal acoustic materials testing to its capabilities.
The FAA is considering amending its controversial rule upgrading flammability standards for thermal and acoustic insulation. The industry wasted no time in letting the agency know of its concern about the unexpected scope of the rule–which became effective on September 2–with the result that the agency has already taken steps to mitigate the burden on business aircraft owners and operators.
Controversy continues to swirl around the FAA’s September 2005 regulations regarding aircraft thermal and acoustic insulation. The agency amended the original regulations after discovering the wording implicated a much broader range of components than intended and recognizing that in many cases compliant parts are not available.
