FAA wants GA users pay additional user fees that to match the airline
users. I don't think that's justified. Read the following paragraphs
regarding to recent ConAir CRJ crash quoted from ABC News:

--------------------
Although Blue Grass Airport's main runway is 7,000 feet, for some
reason the plane departed Sunday from the 3,500-foot general aviation
runway. The twin-engine CRJ-100 would have needed 5,000 feet to fully
get off the ground, aviation experts said.

There also were clues for the pilot: Signs marking the right way. Less
lighting. And severely cracked concrete not the type of surface
typically found on runways for commercial routes.

.... the main runway, which had been repaved last week.

GA airplanes use "severely cracked and less lid" runways comparing to
the commercial jets use the brand new runway that just paved last week.
And now FAA want GA to pay additional fee to match the commercial
users? No way.
