Narrative:

Student pilot was practicing normal takeoffs and lndgs with instructor guidance. Several takeoffs and lndgs successfully completed without incident. Normal touchdown made with 10 degree flaps setting and approach speed of 75 mph at XA45 on dec/xa/99 on runway 33 at iyk. Aircraft settled onto runway 33 without any problem. Instructor informed student to begin thinking about use of the brakes to slow for exiting runway 33. Student applied medium to strong pressure on toe brakes, but applied uneven braking with toe brakes during landing ground rollout deceleration, to slow aircraft to exit runway. Aircraft moved right of centerline, toward r-hand side of runway 33. Right tire skidded. Instructor directed student immediately to release toe brakes, roll straight on runway 33, to stop the skidding motion and to avoid sideloading the aircraft, but was unable to steer aircraft clear of taxiway marker sign B2. Aircraft rolled nosewheel first, through marker sign B2 and was stopped just past sign. Aircraft engine stopped. Sign damaged. No injury to student and instructor. Instructor and student secured aircraft system and exited aircraft to push airplane back to FBO. A telephone report was immediately made to the FBO owner of aircraft and the iyk airport manager. WX: sky clear and calm surface winds. No personal injuries preventive measure: thorough prebriefing on use of toe brakes. Maintain directional control of aircraft, closely monitoring student actions. Allow no deviation from rolling out, deceleration on runway centerline until aircraft slows to safe and slow taxi speed prior to using any brakes. Practice taxiing with student and show effective use of brakes without deviating right or left of taxi ground track along yellow taxiway markings and runway ctrlines (dashed white markings).

Title: C150 INSTRUCTIONAL FLT IYK. STUDENT LEARNS ABOUT TOW BRAKES THE HARD WAY. ACFT AND TXWY BENT.

Narrative: STUDENT PLT WAS PRACTICING NORMAL TKOFS AND LNDGS WITH INSTRUCTOR GUIDANCE. SEVERAL TKOFS AND LNDGS SUCCESSFULLY COMPLETED WITHOUT INCIDENT. NORMAL TOUCHDOWN MADE WITH 10 DEG FLAPS SETTING AND APCH SPD OF 75 MPH AT XA45 ON DEC/XA/99 ON RWY 33 AT IYK. ACFT SETTLED ONTO RWY 33 WITHOUT ANY PROB. INSTRUCTOR INFORMED STUDENT TO BEGIN THINKING ABOUT USE OF THE BRAKES TO SLOW FOR EXITING RWY 33. STUDENT APPLIED MEDIUM TO STRONG PRESSURE ON TOE BRAKES, BUT APPLIED UNEVEN BRAKING WITH TOE BRAKES DURING LNDG GND ROLLOUT DECELERATION, TO SLOW ACFT TO EXIT RWY. ACFT MOVED R OF CTRLINE, TOWARD R-HAND SIDE OF RWY 33. R TIRE SKIDDED. INSTRUCTOR DIRECTED STUDENT IMMEDIATELY TO RELEASE TOE BRAKES, ROLL STRAIGHT ON RWY 33, TO STOP THE SKIDDING MOTION AND TO AVOID SIDELOADING THE ACFT, BUT WAS UNABLE TO STEER ACFT CLR OF TXWY MARKER SIGN B2. ACFT ROLLED NOSEWHEEL FIRST, THROUGH MARKER SIGN B2 AND WAS STOPPED JUST PAST SIGN. ACFT ENG STOPPED. SIGN DAMAGED. NO INJURY TO STUDENT AND INSTRUCTOR. INSTRUCTOR AND STUDENT SECURED ACFT SYS AND EXITED ACFT TO PUSH AIRPLANE BACK TO FBO. A TELEPHONE RPT WAS IMMEDIATELY MADE TO THE FBO OWNER OF ACFT AND THE IYK ARPT MGR. WX: SKY CLR AND CALM SURFACE WINDS. NO PERSONAL INJURIES PREVENTIVE MEASURE: THOROUGH PREBRIEFING ON USE OF TOE BRAKES. MAINTAIN DIRECTIONAL CTL OF ACFT, CLOSELY MONITORING STUDENT ACTIONS. ALLOW NO DEV FROM ROLLING OUT, DECELERATION ON RWY CTRLINE UNTIL ACFT SLOWS TO SAFE AND SLOW TAXI SPD PRIOR TO USING ANY BRAKES. PRACTICE TAXIING WITH STUDENT AND SHOW EFFECTIVE USE OF BRAKES WITHOUT DEVIATING R OR L OF TAXI GND TRACK ALONG YELLOW TXWY MARKINGS AND RWY CTRLINES (DASHED WHITE MARKINGS).
