Narrative:

Upon letdown to mmu, approach was vectoring us to go behind a slower commuter propeller jet, and as I was hand flying the aircraft, I looked out the left window and saw the traffic as it was called out by ATC. Copilot advised me I was 100 ft low, TCASII system on aircraft advised same and the controller said I was right over traffic and what was my altitude. First officer replied level at our assigned altitude. Reason: not paying attention. Controller mentioned it no more. Things like this happen and will happen again. That's why we have two pilots, altitude alert system and TCASII!

Title: ALTDEV ALT OVERSHOT

Narrative: UPON LETDOWN TO MMU, APCH WAS VECTORING US TO GO BEHIND A SLOWER COMMUTER PROP JET, AND AS I WAS HAND FLYING THE ACFT, I LOOKED OUT THE L WINDOW AND SAW THE TFC AS IT WAS CALLED OUT BY ATC. COPLT ADVISED ME I WAS 100 FT LOW, TCASII SYS ON ACFT ADVISED SAME AND THE CTLR SAID I WAS RIGHT OVER TFC AND WHAT WAS MY ALT. FO REPLIED LEVEL AT OUR ASSIGNED ALT. REASON: NOT PAYING ATTN. CTLR MENTIONED IT NO MORE. THINGS LIKE THIS HAPPEN AND WILL HAPPEN AGAIN. THAT'S WHY WE HAVE TWO PLTS, ALT ALERT SYS AND TCASII!
