Narrative:

I was flying with one of my students. We were doing touch-and-goes at the airport. We accomplished the first landing of the day with a hard landing; but thought nothing of it. The landing was not out of the ordinary for a student pilot. The following landing as the airplane set down; felt a little off. I thought we had blown a tire on the right main. I took the controls from my student and proceeded to control the aircraft. At this point in time the right main strut assembly departed the aircraft and we began sliding on the remaining part of the strut. I brought the aircraft to a stop on the runway and proceeded to get out. No injuries to report; and the aircraft is in relatively good condition. The right main assembly needs to be replaced and the stabilator was impacted by the tire assembly. It will more than likely need to be replaced or re-skinned at the least. The aircraft was preflted with no discrepancies visible.

Title: PA-28 STRUT ASSEMBLY FAILED AFTER HARD LANDING.

Narrative: I WAS FLYING WITH ONE OF MY STUDENTS. WE WERE DOING TOUCH-AND-GOES AT THE ARPT. WE ACCOMPLISHED THE FIRST LNDG OF THE DAY WITH A HARD LNDG; BUT THOUGHT NOTHING OF IT. THE LNDG WAS NOT OUT OF THE ORDINARY FOR A STUDENT PLT. THE FOLLOWING LNDG AS THE AIRPLANE SET DOWN; FELT A LITTLE OFF. I THOUGHT WE HAD BLOWN A TIRE ON THE R MAIN. I TOOK THE CTLS FROM MY STUDENT AND PROCEEDED TO CTL THE ACFT. AT THIS POINT IN TIME THE R MAIN STRUT ASSEMBLY DEPARTED THE ACFT AND WE BEGAN SLIDING ON THE REMAINING PART OF THE STRUT. I BROUGHT THE ACFT TO A STOP ON THE RWY AND PROCEEDED TO GET OUT. NO INJURIES TO RPT; AND THE ACFT IS IN RELATIVELY GOOD CONDITION. THE R MAIN ASSEMBLY NEEDS TO BE REPLACED AND THE STABILATOR WAS IMPACTED BY THE TIRE ASSEMBLY. IT WILL MORE THAN LIKELY NEED TO BE REPLACED OR RE-SKINNED AT THE LEAST. THE ACFT WAS PREFLTED WITH NO DISCREPANCIES VISIBLE.
