Narrative:

During initial climb, I was looking out at traffic we were following and was late starting my leveloff at assigned altitude of 5000 ft. I initiated at about 4900 ft, but due to high rate of climb and the fact that we had already accelerated to 250 KTS, I ballooned to 5400 ft before I was able to stop ascent and descend to 5000 ft. The controller noted my altitude, reiterated the assigned altitude and said to descend to assigned altitude. At about that time, I got a TCASII RA to the east with indicated vertical separation 900 ft higher. I was already descending at this point and the TA was resolved after about 3-5 seconds. One of my concerns when looking outside to visually acquire the traffic we were following, was that it was a B727. After watching its takeoff roll, I thought to be fairly heavy. I didn't necessarily want to fly too closely or directly in its wake, as I ws concerned with turbulence associated with wingtip vortices. This concern was well founded as about 2 mins after the altitude excursion I did experience some wake turbulence. It was controllable with only about a 5-8 degree roll from wings level, but it had an accompanying jolt that is sometimes mildly disconcerting to passenger.

Title: A CARJ CREW DURING CLB, OVERSHOT ASSIGNED ALT.

Narrative: DURING INITIAL CLB, I WAS LOOKING OUT AT TFC WE WERE FOLLOWING AND WAS LATE STARTING MY LEVELOFF AT ASSIGNED ALT OF 5000 FT. I INITIATED AT ABOUT 4900 FT, BUT DUE TO HIGH RATE OF CLB AND THE FACT THAT WE HAD ALREADY ACCELERATED TO 250 KTS, I BALLOONED TO 5400 FT BEFORE I WAS ABLE TO STOP ASCENT AND DSND TO 5000 FT. THE CTLR NOTED MY ALT, REITERATED THE ASSIGNED ALT AND SAID TO DSND TO ASSIGNED ALT. AT ABOUT THAT TIME, I GOT A TCASII RA TO THE E WITH INDICATED VERT SEPARATION 900 FT HIGHER. I WAS ALREADY DSNDING AT THIS POINT AND THE TA WAS RESOLVED AFTER ABOUT 3-5 SECONDS. ONE OF MY CONCERNS WHEN LOOKING OUTSIDE TO VISUALLY ACQUIRE THE TFC WE WERE FOLLOWING, WAS THAT IT WAS A B727. AFTER WATCHING ITS TKOF ROLL, I THOUGHT TO BE FAIRLY HVY. I DIDN'T NECESSARILY WANT TO FLY TOO CLOSELY OR DIRECTLY IN ITS WAKE, AS I WS CONCERNED WITH TURB ASSOCIATED WITH WINGTIP VORTICES. THIS CONCERN WAS WELL FOUNDED AS ABOUT 2 MINS AFTER THE ALT EXCURSION I DID EXPERIENCE SOME WAKE TURB. IT WAS CONTROLLABLE WITH ONLY ABOUT A 5-8 DEG ROLL FROM WINGS LEVEL, BUT IT HAD AN ACCOMPANYING JOLT THAT IS SOMETIMES MILDLY DISCONCERTING TO PAX.
