The town's chances of becoming greener have been curtailed by its proximity to Logan International Airport, which is 0.2 to 2 miles from any given point in the community. The two locations identified for a turbine are 0.75 and 1.25 miles from the airport, according to the DPW. After submitting a permit application early last year, town officials received a verbal report in November from the Federal Aviation Administration that indicated that a 250-foot structure in the vicinity of the DPW site would create, "a potential concern with sound landing and takeoff procedures and may be within or uncomfortably close to critical surface area zones," Hickey stated in a letter to Winthrop's town manager last year.

Wind turbines have the potential to be a hazard to air navigation, according to two new letters AOPA issued recently. While AOPA recognizes the role wind turbines play in green power generation, it is concerned that their tall construction could lead to potential collisions with aircraft and impact the reliability of radar. AOPA made the comments in opposition to a bill in the Washington State legislature and on a request for comments to a wind farm proposed in Nantucket Sound off the coast of Massachusetts.

A recent federal ruling that rejected 13 of 22 proposed wind turbines in Roxbury because of height restrictions was based on incorrect information, after all. As of March 18, the Air Traffic Airspace Branch of the Federal Aviation Administration reversed its Jan. 29 rulings by determining that the 13 turbines will pose no hazards to air traffic.

Construction on a $300 million San Patricio County wind energy facility will move forward on schedule after a compromise between the wind farm's owner and the Federal Aviation Administration was announced Monday. The project was in jeopardy after the FAA objected to 81 of 120 proposed sites for 109 wind turbines because of potential interference with a sombrero-shaped radio beacon that pilots can use to determine their proximity to Corpus Christi International Airport.

This news report was submitted to Windaction.org by Scott Jackson, a reseller of Redriven windmills. Mr. Jackson is seeking to get the Redriven turbine de-certified in the State of California for safety reasons.

Tooborac residents fear a proposed wind farm will make their fire-prone village even more unsafe after a turbine caught fire in South Australia. The turbine burnt scrub near Port Lincoln last month at the height of a prolonged heatwave. Tooborac, about 20km from Lancefield, has been earmarked for a 70-turbine wind farm for more than five years by Transfield Services.

One of two wind-power developers behind a proposed local project said Wednesday he was baffled by a recent federal ruling that rejected 13 of 22 turbines because of height restrictions. However, Record Hill Wind LLC Principal Rob Gardiner said he didn't believe the Federal Aviation Administration ruling would hinder the $120 million project. "We are treating this seriously because this is a federal agency," Gardiner said.

State investigators from the Public Service Commission are looking into the fiery collapse of a wind power turbine at a turbine farm in Clinton County. A preliminary examination by Nobel Environmental Power, owner of the $200 million, 65-turbine Altona Wind Park, and General Electric Co., manufacturer of the 1.5-megawatt turbines, found "wiring anomalies" prevented two turbines from shutting down as designed during a power outage.

Noble Environmental Power officials say they have detected a "wiring anomaly" in two Altona wind turbines, including the one that snapped in half last Friday. As the preliminary investigation continues into how a massive turbine suddenly collapsed, Noble officials said this week that the entire wind park experienced a loss of power Friday and that two of its 65 turbines apparently malfunctioned.

Many residents were shocked that a massive wind-turbine could come tumbling down and officials say it could take months to learn why one collapsed Friday. Mike Fellion flew over the wreckage Saturday morning and was amazed to see that pieces of the structure appeared to have been thrown "about a quarter-mile away."

Noble Environmental Power has confirmed that a turbine collapsed at its Altona, N.Y., wind park Friday morning, but said no one was injured in the collapse and ensuing fire. In a statement released by the company Friday, company spokeswoman Maggy Wisniewski confirmed one turbine had collapsed and that a small fire resulted, but she refused to speak on the record with a NewsChannel 5 reporter.

A wind developer that became a "lightning rod" for the industry when one of its turbines started shedding ice in December, has revealed its latest strategy for dealing with ice build-up, writes Rachel Johnson. ..."We knew icing would occur but believed our turbines would stop in the event of an ice build up," he said. The investigation revealed that the most widely available guidelines on icing, including those from the BWEA, had said that wind turbines are designed to shut down in the event of an ice build up.

As the owner of Gisborne's Farmers Air Limited, Mr Stevenson has been flying for 45 years and services over 25 farms in the Tararua District. His message was clear. "There are serious safety implications for aerial topdressers. I've seen far too many people killed by wires, poles and other obstructions - it's only a matter of time."

A 50-ton structure fell 246 feet to the frozen ground on Saturday when the blades of a turbine under construction east of Waverly caught wind and started rotating at a speed reaching 60 rpm. The hub housing the generating components of the Cannon II turbine and the structure's three 177-foot blades collapsed after spinning for hours at the mercy of the wind, says Waverly Light and Power General Manager Diane Johnson. A gust caught the blades prematurely on Friday.

One of the three 60-foot-tall wind turbines at the edge of the Perkins High School student parking lot lays on the ground. The pole was removed from the 4-foot deep, 60-ton concrete base. ..."We have no updates," he said. "The manufacturer is finalizing the investigation as to the malfunction of the blades."

Part of a wind turbine under construction broke apart Saturday morning. The problem started Friday when construction crews were installing a second wind turbine for Waverly Light and Power. During the process, a construction error caused the rotor and blades to start moving in the wind prematurely - spinning uncontrollably and unable to stop until it broke.

The construction company, ICS of North Dakota, lifted the wind turbine rotor assembly, to which the blades attach, 246 feet high into place late yesterday afternoon. After it was lifted it was discovered the blades were not ‘feathered' or turned properly so they could not catch the wind. In the position the blades are in, the wind caught the blades causing them to spin. When this was discovered, the Bremer county sheriff's department was notified and all personnel were evacuated, including two homeowners who were outside of the recommended danger zone.

The Federal Aviation Administration is saying "not yet" on the proposed wind farm project for Nantucket Sound, issuing a "Notice of Presumed Hazard" Feb 13. "Initial findings of this study indicate that the structure as described exceeds obstruction standards and/or would have an adverse physical or electromagnetic interference effect upon navigable airspace or air navigation facilities," the FAA notice issued Feb. 13 reads. "Pending resolution of the issues described below, the structure is presumed to be a hazard to air navigation."

The FAA's "Notice of Presumed Hazard" warns that the 130 proposed turbines could have an "adverse physical or electromagnetic interference effect upon navigable airspace or air navigation facilities." The report warns the rotating blades of the turbines could cause unwanted "clutter" in radar systems. To correct the problem, the FAA study recommends an upgrade of the radar system located at the Massachusetts Military Reservation, where regional air traffic control is conducted.

HYANNIS, Mass. -- After five years of strong objections by the Barnstable, Martha's Vineyard, and Nantucket airports and others on the safety of the 400,000 flights per year over Nantucket Sound, the Federal Aviation Administration (FAA) today formally issued a Notice of Presumed Hazard for the Cape Wind project. Cape Wind is proposing a 44 story, 25 square mile wind project centered under the flight paths between Cape Cod, Martha's Vineyard, and Nantucket. The project would affect FAA radar sites in North Truro, Nantucket, and Otis Air Force Base that provide detection of aircraft for Air Traffic Control (ATC).
