The FAA, EASA and Transport Canada approved Goodrich's rotor-blade ice-protection system (Rips) for the AgustaWestland AW139 medium twin, the Charlotte, N.C.-based aircraft systems supplier announced yesterday.

Proposed changes to FAR 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. Changes would add new icing certification standards for engines and engine installations and components such

AgustaWestland (Booth No. 7020) has received FAA and EASA certification for the full ice-protection system (FIPS) on its AW139 medium twin helicopter.

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.

The NTSB has ruled that last February’s crash of a Colgan Air Q400 on the outskirts of Buffalo, N.Y., was due to the captain’s inappropriate actions in response to the activation of the stick shaker. Its report, released at a press conference yesterday, said the pilot pulled back on the control column when the shaker activated, placing the twin turboprop into an accelerated aerodynamic stall.

The FAA yesterday issued a final rule that prohibits Part 91K, 135 and 121 operators from taking off with “polished frost”–meaning frost buffed to make it smooth–on an aircraft’s wings, stabilizers and control surfaces. The new rule will take effect on Jan. 30, 2010. The FAA already prohibits major and regional air carriers from operating with polished frost.

Coincidental to the early taste of winter weather the Northeast received in mid-October, NBAA–in conjunction with local airport user groups and state business aviation associations–sponsored a pair of cold-weather operational seminars aimed at exploring the challenges and threats presented by in-flight and ground icing, as well as runway contamination.
