 The provisions of  part 23 (airframes) and part 33 (engines) are, in my
 judgment excellent sets of  engineering guidelines detailing all of the
 considerations that should be carefully incorporated into the design of
 an aircraft or engine.
 
  The problem is not the regulations.   The problem is the next step:
 HOW DO YOU SHOW YOU HAVE COMPLIED WITH THE REGULATIONS.
 
  This issue is where the incredible burden and economic costs arise in
 this process.
  
 There is, no longer, any room for "experience" and "judgment" in this
 whole area.
 
  One common complaint is that the FAA is unable to make a decision that
 "enough is - - good enough".
