Human Factors
This [event] occurred departing with self announcing on the CTAF. On initial climb; approaching appropriate altitude to turn crosswind; I made my call for traffic right crosswind [Runway] 17 and moments later I heard a garbled announcement with unclear airport name then a clear announcement for right crosswind announcement. I made a second traffic right crosswind [Runway] 17 announcement. Clearing looks were done; and turned crosswind. Approximately 100 below TPA as we continued to climb; clearing looks were done left and right and I announced traffic right downwind [Runway] 17; Sundance. We turned right downwind and just leveled off when a green and white twin was directly in front of us. I nosed down to avoid impact and went under the belly of the twin. The pilot of the twin then got on the radio and said 'that was close.' The garbled call was the twin who took off after us from Sundance; overtook us in crosswind after coming from behind us; turned crosswind in front of our path and cut us off. The problem was caused simply by several factors. The twin pilot who took off after us failed to [make] clear announcements. The twin pilot should not overtake in the pattern. The twin pilot should allow proper takeoff separation and fly correct patterns.
PA28 pilot reports being over taken in the pattern by a light twin departing after the reporter; causing a NMAC.
