FAA Issues NPRM on Icing Detection System

The FAA has issued a NPRM (notice of proposed rulemaking) that would require manufacturers of newly certified transport-category aircraft to incorporate an ice-detection system.

The proposal follows a recommendation from the U.S. National Transportation Safety Board that aircraft deicing boots should be activated immediately upon the first indication of airframe icing.

The proposed rule would create FAR Part 25.1419 that would require manufacturers to include a system that either alerted the crew to the first sign of airframe ice, or alerted the crew to the presence of conditions conducive to icing.

Following such an alert, the aircraft's deicing system would have to either automatically and continuously activate the deicing system or alert the crew to do it.

Comments concerning the NPRM are due by July 25, 2007.  05-05-2007.
