Well, I was flying VFR with my instuctor in a Piper Cherokee PA-28. We had just left one of the training areas used by the local flight school . It was a small runway on a inhabited island in Conception Bay, Newfoundland.
We had just crossed over the eastern side of the island and were over water. I was climbing to 1500ft ASL to join the circuit into St. John's airport on an extended downwind. We were in communication with St. John's tower.
All of a sudden, a Cessna 172 floatplane flew right in front of us and was coming straight at us. He flew over us with about 150ft to spare. Needless to say, my instructor and I were s**tbaked. We contaced the tower and told them of the incident and they told us that the 172 was neither radar identified or in radio contact.
Since we were in a nose up position in a climb (about 500 ft/min), we could not see him. It was a perfectly clear summers day.
If he had been flying using proper VFR rules and was in radio and radar contact, a near collision could have been avoided.
My instructor and I were shaken up when we landed. We filed a report on the incident, but I never heard anything about it after. The careless use of common sense and lack of proper flying skills almost lead to a mid-air collision.
