Narrative:

During climb I failed to level off at the assigned altitude of FL200. I overshot the leveloff by 500 ft, then immediately returned to assigned altitude. I didn't notice that the altitude preselect/capture button was not engaged on my flight director. As a result, the flight director did not command a leveloff and capture the altitude. Even though the first officer called, 'out of 19 for 20,' I still missed the leveloff. I think a momentary distraction at a critical point in the climb was the cause of the deviation. This is probably a human factors issue, but attempting to evaluate my own performance is difficult. It's hard to be objective. So I will now conduct a personal performance audit, but not by myself. I will ask for the input and guidance from my chief pilot and other instructor pilots in our organization. It's a good idea to do an in-depth evaluation of our performance from time to time, and in light of this recent event, I'm going to do mine now.

Title: G159 CREW HAD ALT OVERSHOT IN ZOB CLASS A.

Narrative: DURING CLB I FAILED TO LEVEL OFF AT THE ASSIGNED ALT OF FL200. I OVERSHOT THE LEVELOFF BY 500 FT, THEN IMMEDIATELY RETURNED TO ASSIGNED ALT. I DIDN'T NOTICE THAT THE ALT PRESELECT/CAPTURE BUTTON WAS NOT ENGAGED ON MY FLT DIRECTOR. AS A RESULT, THE FLT DIRECTOR DID NOT COMMAND A LEVELOFF AND CAPTURE THE ALT. EVEN THOUGH THE FO CALLED, 'OUT OF 19 FOR 20,' I STILL MISSED THE LEVELOFF. I THINK A MOMENTARY DISTR AT A CRITICAL POINT IN THE CLB WAS THE CAUSE OF THE DEV. THIS IS PROBABLY A HUMAN FACTORS ISSUE, BUT ATTEMPTING TO EVALUATE MY OWN PERFORMANCE IS DIFFICULT. IT'S HARD TO BE OBJECTIVE. SO I WILL NOW CONDUCT A PERSONAL PERFORMANCE AUDIT, BUT NOT BY MYSELF. I WILL ASK FOR THE INPUT AND GUIDANCE FROM MY CHIEF PLT AND OTHER INSTRUCTOR PLTS IN OUR ORGANIZATION. IT'S A GOOD IDEA TO DO AN IN-DEPTH EVALUATION OF OUR PERFORMANCE FROM TIME TO TIME, AND IN LIGHT OF THIS RECENT EVENT, I'M GOING TO DO MINE NOW.
