Narrative

ENRTE TO MYF; MY STUDENT AND I WERE CLRED FOR THE ILS RWY 28R APCH. WE HEARD OF TWIN CESSNA CLRED FOR VISUAL RWY 28L AT MYF. MY STUDENT (UNDER THE HOOD) CONTINUED APCH AS NORMAL; ON GS AND LOC; WHILE I SCANNED FOR TFC IN TERMINAL AREA OF MONTGOMERY FIELD. APPROX 1 MI FROM RWYS; I NOTICED THE C340 TURNING BASE FOR WHAT I THOUGHT RWY 28L. HE PROCEEDED TO DRIFT ONTO THE FINAL APCH COURSE FOR THE RWY WE WERE CLRED TO LAND ON; RWY 28R! I NOTIFIED THE TWR OF THE SIT IN FRONT OF ME: 'TWR; THE TWIN CESSNA IS LINING UP FOR RWY 28R.' TWR: 'CHEROKEE XYZ; CHANGE TO RWY 28L; CLRED TO LAND RWY 28L.' 'TWIN CESSNA; YOU WERE INSTRUCTED TO LAND ON RWY 28L 3 TIMES.' I MAINTAINED VISUAL SEPARATION WITH THE TWIN AND INSTRUCTED MY STUDENT TO GO VISUAL AND SIDESTEP TO RWY 28L; WHICH WE DID. THE TWIN TOUCHED DOWN WHILE WE LINED UP WITH RWY 28L; AND WE LANDED SAFELY. I FEEL THIS EVENT TOOK PLACE DUE TO: 1) LACK OF A COMMAND OF THE STANDARD AVIATION LANGUAGE (ENGLISH) BY THE TWIN PLT. 2) LACK OF ATTN BY THE TWIN PLT IN UNDERSTANDING HIS APPROPRIATE RWY ASSIGNMENT (SITUATIONAL AWARENESS). 3) SEE AND AVOID RESPONSIBILITIES NOT PERFORMED BY TWIN PLT IN IDENTING MY ACFT IN VMC. I FEEL A CORRECTIVE ACTION TO THIS FREQUENT EVENT IS TO REQUIRE MORE TRAINING IN FLUENT ENGLISH AVIATION PHRASEOLOGY FOR FOREIGN PLTS; AND MORE SEPARATION BTWN VFR ACFT AND IFR ACFT.
