Are cessna 172 have mmel?
I’m assuming your asking about an MMEL, take note guys 2 M’s. While it’s true an MEL is airplane specific, an MMEL or Master Minimum Equipment List is a template the FAA publishes for a given model such as a CE-525. This template is typically used as a starting point to develop your own serial number specific MEL OR you can sometimes get an LOA from the FSDO allowing you to use the MMEL as an MEL for your specific aircraft. (I’m currently operating my aircraft under such LOA). Unfortunately I did a quick check and there’s no MMEL for a CE-172 listed on the FAA site. Check for yourself at http://fsims.faa.gov/PublicationForm.
