Obviously this is more of a commercial piloting question, than a
recreational one, but...

http://www1.airweb.faa.gov/Regulator...F?OpenDocument

states that the effective date was 1/15/2002.

But I found archived UseNet discussions of it from as far
back as 1994:

http://groups.google.com/group/rec.t...604e97c?hl=en&

So what's with the effective date at the FAA webpage?
Are the effective dates periodically changed for some
reason?

Was the rule not 'effective' for some period(s) of time between
1994 and 2002?
