A 32-year-old advisory circular still used as the basis for showing compliance with in-flight icing protection rules is currently undergoing an “extensive” revision, and the FAA has published a draft version of it for comments. The objective of the revision, said the agency, is to provide a “uniform and modern” means of compliance with regulations for ice-protection requirements.

Helicopter mountain rescue operations are among the most demanding flying there is. Pilots are challenged by pushing the performance envelope of their machines in notoriously unpredictable weather, and when the mission is rescue, they face another layer of difficulty, driven by the desire not only to survive their mission, but to save lives too.

RAYTHEON KING AIR E90, RENO, NEV., MARCH 13, 2002–The NTSB determined the probable cause of the accident was the pilot’s inadequate approach airspeed for the existing adverse meteorological conditions, followed by his delayed action to avert stalling and subsequent loss of control of the airplane. Contributing factors were reduced visibility due to the inclement weather and icing conditions.

Last month the FAA issued a Special Airworthiness Information Bulletin (SW-08-03) containing “recommendations for rotorcraft during icing conditions.” The SAIB describes “procedures to reduce the probability of an engine in-flight shutdown due to ice and snow ingestion,” including special precautions during winter pre-flights and ground power settings.

In the northern hemisphere, it’s that time of year again, when clouds are full of ice and it’s time to dust off those icing training manuals and relearn the pertinent points about handling icing conditions.

MITSUBISHI MU-2, LEWISTON, IDAHO, FEB. 11, 2000–“The pilot failed to follow the flight manual procedures and did not engage the continuous ignition system, resulting in both engines flaming out when ice blocked the air induction system.

The FAA today released a new fact sheet, “Safer Flying in Icing Conditions,” to remind operators that aircraft icing is a “continuing concern in all parts of aviation, from small planes to jumbo jets.” To combat icing-related accidents, the FAA is employing a multi-pronged approach to icing issues, using immediate safety actions and longer-term rule changes.

Sikorsky’s S-92 has successfully completed the artificial icing requirement of the FAA’s icing-certification program, thus preparing the aircraft for its final all-weather-operations certification phase. It has already completed more than 80 percent of the requirements for icing certification and begun natural icing trials, with several successful natural icing events flown to date.

The FAA last month released a final rule governing certification of transport-category (Part 25) airplanes for operation in icing conditions. The new rule, which takes effect October 9, effectively added new material to Part 25, Appendix C, the section that details the so-called icing envelope.
