Cessna 172 Oil Temp

Whats your take on this "new" CO (Carbon monOxide) measurement
requirements at annual. Was our IA just extorting extra time/money?

http://www.faa.gov/avr/arm/arac/arac...nical3_all.doc
11. AC 20-32B, Carbon Monoxide (CO) Contamination in Aircraft - Detection
and Prevention.

Which references standards for transport category aircraft.




Sec. 121.219 references ventalation requirements:
http://www.faa.gov/asd/international...%20Notepad.pdf
"carbon monoxide concentration may not be more than one part in 20,000
parts of air"

Part 121 is the section for air carrier aircraft.



Page 15-6 just references what it can do to you in the Pilots Handbook:
http://av-info.faa.gov/data/training...83-25-4of4.pdf

And they are correct, but hardly regulatory.

What is this CO measurement thing that you are talking about? Are you
saying that somebody has determined that a CO measurement is part of an
annual inspection on a part 91 aircraft? Not anything I've heard about, but
that doesn't say it didn't slip by me. Then again, you may have been part
of the mechanic's Hawaii fund.
