Narrative:

Upon my arrival into the [airport] area; I was experiencing great difficulty in locating the airport. This was my first time flying into [this airport] and unfortunately; my aircraft was not equipped with GPS or navigation radio… communications only. When I called the tower; thinking I was about 5 miles north the controller advised me that I was actually 3 miles and had violated their airspace and was conflicting with his traffic.I have grounded my aircraft until all radio-navigation communication equipment is upgraded to suitable standards; and from now on I will call the tower much further out regardless whether I can see the field or not.
