Taking a proactive approach toward the anti-icing regulations proposed by the FAA in June 2010–and still unscheduled for adoption into the FARs–Spirit AeroSystems (Booth No. C11720) has been working with Wichita State University and an undisclosed supplier to develop two new anti-icing systems for nacelles surrounding large aircraft engines.
Three helicopters being used to warm crops against cold temperatures and frost overnight in Western Palm Beach County, Fla., crashed in the early morning hours of December 8 in separate accidents between 2:10 and 7:40 a.m. The accidents involved two Robinson R44s and one Bell 206L-3. Only the pilot of the 206, the most extensively damaged of the three aircraft, sustained serious injuries.
In its just-released world commercial helicopter market report, research firm Frost & Sullivan expects the segment to expand from 24,625 helicopters in 2009 to 36,946 in 2015.
The FAA has 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 takes effect at the end of this month. Previous FAA guidance recommended removing all wing frost before takeoff, but allowed it to be polished smooth if the aircraft manufacturer’s recommended procedures were followed.
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.
The FAA last month issued a Notice of Proposed Rulemaking (FAA-2007-29281) to remove wording in Parts 91, 125 and 135 that currently allows pilots to take off with frost on wings, stabilizers and flight controls “if the frost has been polished to make it smooth.” The polished frost rules are found in 14 CFR 91.527(a), 125.221(a) and 135.227(a).
The FAA today issued a notice of proposed rulemaking to remove wording in Parts 91, 125 and 135 allowing pilots to take off with frost on wings, stabilizers and flight controls “if the frost has been polished to make it smooth.” The polished frost rules are found in 14 CFR 91.527(a), 125.221(a) and 135.227(a).
A preliminary report issued by the UK Air Accidents Investigation Board on the January 4 crash of Challenger 604 N90AG at Birmingham, England, raises a suspicion that frost or ice on the wing may have been a factor. The aircraft, operated by Epps Aviation of Atlanta on behalf of agricultural machinery manufacturer Agco, had arrived the previous evening at 8:39 p.m. after a nonstop flight from West Palm Beach, Fla.
As I prepared to write this column the television and radio news programs were reporting on the recent spate of business aviation accidents. One of the widely reported accidents that caused considerable concern at the NTSB was the November 28 crash of the Challenger 601 in Montrose, Colo. In this accident the NTSB is investigating airplane performance issues, including the possibility of upper-surface wing ice contamination.
Operators of all U.S.-registered Challenger 600s, 601s and 604s and Canadair Regional Jets, which are derived from the business jet, must incorporate flight manual revisions to ensure that before takeoff the “wing leading edge and upper wing surface are completely free of ice, frost, snow or slush,” under a new AD. The FAA directive (AD 2005-04-07) followed an identical AD from Transport Canada.
