Narrative:

Student landed with minor assistance. To increase confidence and demonstrate ctlability, I let her roll out. Mooney does not have passenger side brakes (pinch hitter students fly from right seat) and she wondered about stopping ability. I initiated braking late, wind apparently shifted (next aircraft took off in opposite direction), and we rolled just off end of runway. Construction was underway (unmarked), and propeller struck construction berm. Propeller tip bent. Shut down (precaution) and had tug move aircraft. Construction and displaced threshold should have been marked. I should have initiated braking earlier. No injuries or other aircraft damage.

Title: INSTRUCTOR PLT OF A MOONEY M20 WENT OFF THE END OF THE RWY DUE TO DELAYED BRAKING DURING LNDG ROLL RESULTING IN A PROP STRIKE ON BERM IN THE RWY OVERRUN AREA.

Narrative: STUDENT LANDED WITH MINOR ASSISTANCE. TO INCREASE CONFIDENCE AND DEMONSTRATE CTLABILITY, I LET HER ROLL OUT. MOONEY DOES NOT HAVE PAX SIDE BRAKES (PINCH HITTER STUDENTS FLY FROM R SEAT) AND SHE WONDERED ABOUT STOPPING ABILITY. I INITIATED BRAKING LATE, WIND APPARENTLY SHIFTED (NEXT ACFT TOOK OFF IN OPPOSITE DIRECTION), AND WE ROLLED JUST OFF END OF RWY. CONSTRUCTION WAS UNDERWAY (UNMARKED), AND PROP STRUCK CONSTRUCTION BERM. PROP TIP BENT. SHUT DOWN (PRECAUTION) AND HAD TUG MOVE ACFT. CONSTRUCTION AND DISPLACED THRESHOLD SHOULD HAVE BEEN MARKED. I SHOULD HAVE INITIATED BRAKING EARLIER. NO INJURIES OR OTHER ACFT DAMAGE.
