ALL placards are required, no excuses for PIC 
Easy replacement by copying and taping missing placard from Section 2 of Aircraft POH/AFM or Type Certificate Data Sheet (TCDS) 
Owner/Operator PRIMARILY responsible for airworthiness 
Have student READ airworthiness &amp; registration certificates 
INOP scenarios: transponder, one strobe light, alternator, missing baggage door placard 
Requiring rental outfits and flying clubs to keep aircraft in airworthy condition, have all required placards legible, and maintenance logbooks available for review is not causing trouble, it&amp;rsquo;s REQUIRED! 
Reporting squawks allows outfits to get those squawks repaired. Not reporting squawks can put your certificates and life in jeopardy, along with others. What about the next renter, possibly a student? 
What is the school&amp;rsquo;s, rental outfit&amp;rsquo;s, or flying club&amp;rsquo;s process for reporting grounding squawks? 
Many places have a sheet for squawks, do they have a sheet for non-squawk cosmetic items such as ink marks in the upholstery, rips in fabric, or cracked plastics? 
The maintenance is not complete until the mechanic&amp;rsquo;s signature on the proper entry is in the appropriate aircraft maintenance logbook. It is not okay to fly based on a phone call from the mechanic, or a conversation in which the mechanic states &quot;it&amp;rsquo;s done&quot; 
Missing compass correction card is easy FAA violation 
Safety of Flight Issues vs. Paperwork Issues, both grounding.
