AD Issued for Cessna 206/207/210 with Certain Turbochargers
On Monday, May 14, 2012, FAA issued an emergency airworthiness directive (AD) due to an unsafe condition on Cessna 206, 207 and 210 airplanes installed with Hartzell Engine Technologies (HET) turbochargers, part numbers (P/Ns) 406610-0005 and 406610-9005. This AD was prompted by a report of an HET turbocharger causing an engine inflight power rollback. Upon investigation, the turbocharger was found to have incorrectly located oil passages in the center housing, causing insufficient oil flow to the bearings. This condition, if not corrected, could result in turbocharger bearing seizure, failure of the turbocharger turbine shaft or wheel, and damage to the airplane.
HET Alert Service Bulletin (ASB) No. 047 (

), dated May 08, 2012, identifies the part numbers and serial numbers of affected turbochargers and describes procedures for removing them from service. To view the AD, go to:

The Terrible “T”s
You may know what the Terrible Twos are, but how about the Terrible Ts? Though her fury can mimic a toddler’s unpredictable tantrums, Mother Nature’s Terrible Ts refer to turbulence, thunderstorms, and tornadoes—all three of which can unleash enormous destructive energy. In the May/June 2012 issue of FAA Safety Briefing (
http://www.faa.gov/news/safety_briefing/
), author James Williams provides readers with tips on how to recognize the warning signs of these pilot nemeses and safely avoid their dangerous effects.
You’ll also find information on the National Weather Service’s Aviation Digital Data Service (ADDS) website, which includes a useful turbulence forecast tool. The ADDS tool uses color contour maps to display turbulence intensity in three categories: none, light, and moderate or greater. Pilots can access the turbulence forecast tool at:
