Narrative:
While climbing to FL240, at about 220, major electric longitudinal trim became inoperative. The first officer then started trying to find a procedure covering that problem. Some time after climbing through 235 we crossed the liberty VOR. The autoplt was engaged and we were climbing at 6-700 FPM. As I looked away to confirm the outbound radial the aircraft climbed through FL240, the altitude alerter sounded at 243, the TCASII announced 'traffic' and the controller called to confirm our altitude at about the same time. I disconnected the autoplt and descended back to 240. We were able to visually sight the 250 traffic when he was 8-10 mi away. This is a classic example of no one minding the store. No matter how insignificant the problem, the first order of business is fly the airplane!

Title: ALTDEV ALT OVERSHOT IN CLB. TCASII TA WARNS OF OPPOSITE DIRECTION TFC IN TIME TO AVERT POTENTIAL CONFLICT LTSS.
Narrative: WHILE CLBING TO FL240, AT ABOUT 220, MAJOR ELECTRIC LONGITUDINAL TRIM BECAME INOP. THE FO THEN STARTED TRYING TO FIND A PROC COVERING THAT PROBLEM. SOME TIME AFTER CLBING THROUGH 235 WE CROSSED THE LIBERTY VOR. THE AUTOPLT WAS ENGAGED AND WE WERE CLBING AT 6-700 FPM. AS I LOOKED AWAY TO CONFIRM THE OUTBOUND RADIAL THE ACFT CLBED THROUGH FL240, THE ALT ALERTER SOUNDED AT 243, THE TCASII ANNOUNCED 'TFC' AND THE CTLR CALLED TO CONFIRM OUR ALT AT ABOUT THE SAME TIME. I DISCONNECTED THE AUTOPLT AND DSNDED BACK TO 240. WE WERE ABLE TO VISUALLY SIGHT THE 250 TFC WHEN HE WAS 8-10 MI AWAY. THIS IS A CLASSIC EXAMPLE OF NO ONE MINDING THE STORE. NO MATTER HOW INSIGNIFICANT THE PROBLEM, THE FIRST ORDER OF BUSINESS IS FLY THE AIRPLANE!
