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.

The East Coast Jets-operated Hawker 800A that crashed Thursday morning at Owatonna (Minn.) Degner Regional Airport, killing all eight on board, briefly touched down on 5,500-foot Runway 30 before the crew decided to abort the landing and attempt a go-around. “The airplane did land and for some reason the flight crew made the decision to take off again,” said NTSB investigator Steven Chealander.
The NTSB has confirmed talk that the Board is “about to release” a report modifying some of its findings in the October 1994 crash of an American Eagle ATR 72 near Roselawn, Ind.
The NTSB conceded its original final report falsely gave the impression that ATR and the French civil aviation authority (DGAC) knew the precise conditions that led to the 1994 crash of a Simmons Airlines ATR 72 near Roselawn, Ind., would, in fact, result in an icing-induced upset. The admission was in response to petitions filed years ago by ATR and DGAC for the NTSB to revise its final report.
When pilots turn their attention to icing, it’s the in-flight kind that garners the most attention and training focus. But ground icing is also critical and has been implicated in a number of accidents. Fortunately, the training material available on ground icing is as voluminous as it is for in-flight icing, and most of it is readily available online for individual use or incorporation into a training program.
RAYTHEON BEECH 400A, BALTIMORE, MD., MAY 1, 2002–Beechjet N498CW, a fractionally owned and operated airplane managed by Flight Options, was substantially damaged during a landing overrun at Baltimore-Washington International Airport. No injuries were reported. The NTSB blamed the captain’s failure to go around.
The FAA released on November 8 a new fact sheet, “Safer Flying in Icing Conditions,” to warn operators that aircraft icing is a “continuing concern in all parts of aviation, from small airplanes 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.

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.
