Narrative:

On training flight with a foreign student. While on the first departure from runway 26 just prior to turning crosswind, the second aircraft in question came into view off the r-hand side of our plane going the opposite direction. Apparently, what in my estimation was a very close, tight downwind for runway 26. We had to snap left to lessen the closure rate. The cause, in my opinion, was a lack of correct radio usage together with a non compliant traffic pattern in accordance with the aim and applicable FARS. As it turned out, the other aircraft was plted by a piper cherokee pilot based here at redlands.

Title: A C152 TRAINING FLT HAS AN NMAC WITH A PA28 ARRIVING UNANNOUNCED NEAR THE XWIND LEG AT L12, CA.

Narrative: ON TRAINING FLT WITH A FOREIGN STUDENT. WHILE ON THE FIRST DEP FROM RWY 26 JUST PRIOR TO TURNING XWIND, THE SECOND ACFT IN QUESTION CAME INTO VIEW OFF THE R-HAND SIDE OF OUR PLANE GOING THE OPPOSITE DIRECTION. APPARENTLY, WHAT IN MY ESTIMATION WAS A VERY CLOSE, TIGHT DOWNWIND FOR RWY 26. WE HAD TO SNAP L TO LESSEN THE CLOSURE RATE. THE CAUSE, IN MY OPINION, WAS A LACK OF CORRECT RADIO USAGE TOGETHER WITH A NON COMPLIANT TFC PATTERN IN ACCORDANCE WITH THE AIM AND APPLICABLE FARS. AS IT TURNED OUT, THE OTHER ACFT WAS PLTED BY A PIPER CHEROKEE PLT BASED HERE AT REDLANDS.
