Flight Crew Took Evasive Action
Human Factors; Procedure
I was descending down to pattern altitude of 1;600 feet to enter the pattern at ZZZ. I saw an aircraft on Foreflight via my ADS-B receiver that was northeast of ZZZ at 1;600 feet. I initially thought that the aircraft was probably inbound to ZZZ. I made my announcements on CTAF; but never heard the other aircraft make any announcements. Once I was at 1;600 feet; my IPAD showed that the other aircraft was at the same altitude (pattern altitude) and basically on a collision course with me. I went full throttle and started an aggressive climb. By the time the aircraft passed directly underneath of me I was only 500 above it. We were only 2 miles from ZZZ airport; well within the class E surface area. (Other aircraft tail number was Aircraft Y.)
Pilot reported taking evasive action to avoid a collision with an aircraft operating without communications within the Class E Airspace.
