When Medical Certificate Expires?
 

I thought I knew the answer, but now I'm not sure.
- As an part 121 FO, I got a Class I Med Certificate February 2010. Does this certificate expire at the end of February or end of March?

FAA web site says:
"A first class medical certificate is valid for the remainder of the month of issue; plus

• 6 calendar months for operations requiring a first class medical certificate if the airman is age 40 or over on or before the date of the examination, or
• 12-calendar months for operations requiring a first-class medical certificate if the airman has not reached age 40 on or before the date of examination, or
• 12 calendar months for operations requiring a second class medical certificate, or"

Thanks for the help.

I was told there would be no math
 

I thought and was taught it would expire at the end of same month issued.

I seem to recall this was a question on the private written, and that was the correct answer.

That first line "A first class medical certificate is valid for the remainder of the month of issue; plus" is confusing.

The end of February is "plus" twelve months. It expires March 1st.

Actually to be perfectly correct it would expire on the last day of the following February at 11:59:59 local. IE on March 1 you couldn't use it.

Well there's three posts in a row that agree!! An APC first? :)

Close. However, to be perfectly correct, 11:59:59 is still the last day of February. The medical would still be good at 11:59:59, (23:59:59). It won't expire until 00:00. Which would occur on March 1st.:D

Okay a third class medical which was issued to a 39 year old pilot 02-29-2008, when would it expire?

2/28/2011 would be it's last day.

No, it's last day would be 2/28/2013.

2008+3 = 2011
