'Puddle of Mudd' Singer Wes Scantlin -- Charges Dropped from JetBlue Arrest

"Puddle of Mudd" singer Wes Scantlin just dodged a stint in prison because charges against him for an alleged drunken brawl on a JetBlue flight ... have been dropped!

TMZ broke the story ... Scantlin was arrested in Austin, TX back in September, after he allegedly got into a booze-fueled argument with a flight attendant. The plane was forced to make an emergency landing and Scantlin was charged with public intoxication.

Scantlin was adamant he did nothing wrong -- and earlier this week he was vindicated when a judge dismissed the charges due to "insufficient evidence". 

Scantlin struck a plea deal for cocaine possession in July -- and was ordered to obey all laws for 18 months ... or he could face a prison sentence.

Calls to Scantlin's people weren't returned.
