How geology and climate control vegetation composition and distribution in the Yellowstone Geoecosystem
Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Cathy Whitlock, Regents Professor with the Department of Earth Science and the Paleoecology Lab at Montana State University. In Yellowstone, geology and ecology go hand in hand. In fact, the geology of Yellowstone can be mapped by its vegetation! For example, the glacial clays in the Lamar and Hayden valleys are rich in nutrients, like calcium and magnesium, and have high water-holding capacity; these qualities favor growth of grassland and sagebrush steppe. These landscapes are called the “Serengeti
FEMA Awards Over $1.1 Million to New Hampshire for Laconia Flood Control Project
FEMA Awards Over $1.1 Million to New Hampshire for Laconia Flood Control Project The Federal Emergency Management Agency will be sending more than $1.1 million to the State of New Hampshire to reimburse the City of Laconia for part of the cost of replacing an undersized culvert with a larger bridge to help avoid future flood damage. The $1,135,411 Hazard Mitigation Grant Program (HMGP) grant will fund the replacement of a culvert on Hillard Road in Laconia with a 21-foot clear span bridge to reduce the frequency and severity of flooding, and decrease overtopping of the roadway during large storm events.
American Bonanza Society Control Cable Turnbuckle Recommendation
American Bonanza Society Control Cable Turnbuckle Recommendation The American Bonanza Society (ABS) posted an article on January 30, 2019, that addressed some concerns over corrosion found on aileron and rudder cable turnbuckles hidden under the safety wire and one occurrence where the rudder cable turnbuckle failed. All of these occurrences happened where the turnbuckle is positioned beneath a heater duct or in the case of the rudder cable, the overheat inlet air duct. After reviewing the original article, the FAASTeam feels it would be prudent to disseminate the information again to ensure all affected aircraft are inspected. Below are important
Mooney M20 Control Wheel Shaft Fatigue Cracks
The FAA is investigating the report of a control wheel separation on a Mooney M20C aircraft due to fatigue cracks in the control shaft or control wheel attachment hub. This failure might result in momentary loss of control of the aircraft until the pilot or copilot is able to regain control with the second control wheel. This may reduce the capability of the airplane or the ability of the crew to cope with adverse operating conditions to the extent that there may be a significant reduction in safety margins, especially in certain phases of flight, such as takeoff and landing.
