Human Factors
I was flying to Lincoln; California (LHM) to practice touch and goes in a PA28R 180. I entered the traffic pattern for Runway 15 on a 45-degree entrance; calls previously had been done at approximately 5 miles and 2 miles out. I entered the downwind; completed my GUMPS check and proceeded to base. A single engine Cessna took off from Runway 15 while I was on final. I completed the touch and go and climbed out to enter the crosswind; call made; at approximately 500 feet above ground level. The Cessna in the pattern flew an exaggerated upwind pattern; apparently he had made a crosswind call; and a downwind call and I crossed in front of his line of flight. I was notified by the pilot of the Cessna of the error; and apologized for the intrusion. I noticed his aircraft to my left hand side; approximately 300 feet to the inside of the pattern 50 feet lower. I exited the parallel downwind and flew a right hand one-eighty turn out and reentered the downwind leg. The contributing factors to the intrusion was my low time in a PA28R with fixation on the departure processes; likely not hearing and registering mentally the crosswind and downwind calls by the Cessna. An additional error was not announcing my intention to fly a touch and go for Runway 15.
PA28R pilot reported a NMAC in the pattern at LHM airport.
