Narrative:

During initial climb out from fll, we were assigned an intermediate altitude of 5000' MSL. Passing 4300' MSL, a TCAS warning sounded, showing traffic at 11 O'clock and 1700' above. By the time we visly acquired the traffic we were at 5000' and climbing. Captain immediately initiated level off. The aircraft reached 5400' MSL then descended back to 5000' MSL. In this case, the timing of the TCAS warning proved to be a distraction that caused an altitude overshoot.

Original NASA ASRS Text

Title: DISTR OF TCASII TA CAUSES ALT OVERSH00T AND A CONFLICT.

Narrative: DURING INITIAL CLBOUT FROM FLL, WE WERE ASSIGNED AN INTERMEDIATE ALT OF 5000' MSL. PASSING 4300' MSL, A TCAS WARNING SOUNDED, SHOWING TFC AT 11 O'CLOCK AND 1700' ABOVE. BY THE TIME WE VISLY ACQUIRED THE TFC WE WERE AT 5000' AND CLBING. CAPT IMMEDIATELY INITIATED LEVEL OFF. THE ACFT REACHED 5400' MSL THEN DSNDED BACK TO 5000' MSL. IN THIS CASE, THE TIMING OF THE TCAS WARNING PROVED TO BE A DISTR THAT CAUSED AN ALT OVERSHOOT.
