RWY EXCURSION.

Narrative

ON MAR/WED/92; I TOOK MY SECOND LESSON WITH MY FLT INSTRUCTOR. AFTER ABOUT 20 OR 30 MINS OF BRIEFING ON THE GND AS TO THE VARIOUS MANEUVERS HE WOULD EXPECT ME TO DO; WE TAXIED TO TKOF. HE SAID HE WOULD BE DOING AN ENG OUT ON TKOF; AN ENG OUT AT ALT; EXPLAINED RECOVERY TECHNIQUES; STALLS; AND PERHAPS 1 OR 2 OTHER CRITICAL MANEUVERS. MY FLT INSTRUCTOR HAD ALSO SUPPLIED ME WITH A VIDEO TAPE ON MULTI-ENG OPS; BUT I HAD NOT VIEWED THAT TAPE BY THE TIME WE TOOK THE LESSON ON WED. WE TAXIED TO RWY 22; DID A RUNUP; AND PREPARED TO TKOF ON 22. I ASKED HIM SPECIFICALLY IF HE PLANNED TO PULL AN ENG ON TKOF. HE SAID YES; BUT WOULD DO IT WELL BEFORE WE REACHED A 40 MPH AIRSPD. I THEN ACCELERATED THE THROTTLES TO FULL. WITHIN ABOUT 5 TO 10 SECONDS (PERHAPS SOONER; I THINK TIME GOES BY FASTER THAN ONE REMEMBERS IT); WE BEGAN A SEVERE YAW TO THE L. I THINK I TRIED TO COMPENSATE AS I WOULD NORMALLY DO IN MY SMA BY APPLYING R RUDDER. I DO NOT REMEMBER RETARDING THE R THROTTLE IMMEDIATELY AS I WAS INSTRUCTED TO DO IN THE GND BRIEFING. AS WE YAWED TOWARDS THE EDGE OF THE RWY; I BELIEVE I CONSCIOUSLY YIELDED THE CTLS TO MY FLT INSTRUCTOR; EXPECTING HIM TO TAKE THE CTLS AND CTL THE ACFT. WE THEN WENT OFF THE RWY AND I THINK I FELT THE THROTTLES BEING ACCELERATED. IT SEEMED WE PICKED UP SPD AS WE WENT OFF THE RWY INTO THE GRASS. I REMEMBER THINKING -- SOMEWHAT SILLY IN RETROSPECT -- 'IS HE GOING TO TRY TO GET THIS THING AIRBORNE?' WE CAME TO A HALT OFF THE RWY; BUT NOT BEFORE THE ACFT'S L MAIN GEAR COLLAPSED AND THE ACFT SKIDDED TO A HALT. I COULD SEE THAT THE L MAIN WINGTIP TANK WAS DAMAGED AND THE L PROP WAS BENT. AFTER WE STOPPED; MY FLT INSTRUCTOR TURNED OFF THE APPROPRIATE SWITCHES AND WE EXITED THE ACFT. WE WERE PICKED UP BY A FIRE ENG WHICH HAD MADE ITS WAY ACROSS THE RWY AND TAKEN BACK TO THE FBO. NEITHER OF US WAS HURT. I DON'T THINK THE ENTIRE EVENT SITUATION INCIDENT ACCIDENT TOOK MORE THAN 10 SECONDS; GIVE OR TAKE 4 OR 5. AGAIN; IT IS HARD TO REMEMBER THE PASSAGE OF TIME. SUPPLEMENTAL INFO FROM ACN 205147: SHORTLY AFTER THE TKOF ROLL BEGAN; THE L ENG WAS FAILED BY FULLY RETARDING THE MIXTURE CTL. THE AIRSPD INDICATOR HAD NOT YET BEGUN TO REGISTER. THE STUDENT FROZE AT THE CTLS. THE RESPONSE (OR LACK OF RESPONSE) BY THE STUDENT TO THE LOSS OF PWR FROM THE L ENG WAS NOT PREDICTABLE AFTER THE THOROUGH AND REPEATED PREFLT BRIEFING. HOWEVER; DAMAGE TO THE ACFT MIGHT HAVE BEEN AVOIDED IF R RUDDER BEING USED TO COUNTERACT L YAW HAD BEEN RELEASED IMMEDIATELY UPON RETARDING THE THROTTLES AND ELIMINATING THE ADVERSE YAW TO THE L.
