Warlord,
a couple points...
1-answer the question the EPSQ asks. Being accused of a crime (arrested, then being dismissed or plea-bargained down to a lesser crime) does not mean you are guilty of the crime (or that the crime is on your record). If you are asked for a criminal record, then list what you have been convicted of. If you are asked if you have ever been accused of a crime, then list the ones you have been accused of (you will have time to explain what happen if it matters).
As a part time deputy, law enforcement can charge someone with anything (well almost), but it is up to the court system to decide/prove they actually did it.
2 - The average pilot should only need a secret level clearance. This will not be as involved as the clearance required for some other programs (Intel, crypto).
I wouldn't stress to much. Just look at what they are asking for in the question, and answer it.
