Narrative:
On the afternoon of may, my friend, a private pilot, and I were returning to our home airport from a short flight to a nearby airport. She was having trouble with the intercom (ie, my side couldn't hear very well at all). About 5 mi from the airport, the tower controller told her to report 2 mi base, or so she thought. I did not hear this order. A friend approached from the same direction, and heard the controller say something different. (We believe he was a tower trainee.) my pilot either miscommunicated her position or the controller didn't tell her of the converging sierra (aircraft Y) traffic. The sierra pilot said she (our plane), crossed on base leg in front of him about a wing span. She never saw him and I was checking traffic out the front and right window. The sierra saw us. We never saw him. The tower may not have realized the closeness.

Title: NMAC BTWN A BEECH SIERRA, BE24, ON FINAL AND THE RPTR IN A CESSNA 182 TURNING BASE LEG IN FRONT OF THE SIERRA.
Narrative: ON THE AFTERNOON OF MAY, MY FRIEND, A PVT PLT, AND I WERE RETURNING TO OUR HOME ARPT FROM A SHORT FLT TO A NEARBY ARPT. SHE WAS HAVING TROUBLE WITH THE INTERCOM (IE, MY SIDE COULDN'T HEAR VERY WELL AT ALL). ABOUT 5 MI FROM THE ARPT, THE TWR CTLR TOLD HER TO RPT 2 MI BASE, OR SO SHE THOUGHT. I DID NOT HEAR THIS ORDER. A FRIEND APCHED FROM THE SAME DIRECTION, AND HEARD THE CTLR SAY SOMETHING DIFFERENT. (WE BELIEVE HE WAS A TWR TRAINEE.) MY PLT EITHER MISCOMMUNICATED HER POS OR THE CTLR DIDN'T TELL HER OF THE CONVERGING SIERRA (ACFT Y) TFC. THE SIERRA PLT SAID SHE (OUR PLANE), CROSSED ON BASE LEG IN FRONT OF HIM ABOUT A WING SPAN. SHE NEVER SAW HIM AND I WAS CHKING TFC OUT THE FRONT AND R WINDOW. THE SIERRA SAW US. WE NEVER SAW HIM. THE TWR MAY NOT HAVE REALIZED THE CLOSENESS.
