Narrative:

Aircraft impacted runway 26 at N70 after onset of stall occurred on final approach. Student pilot had reduced power to idle and extended full flaps dues ot high altitude (200' AGL) at runway threshold. Student failed to pitch nose down to maintain recommended 85 mph approach airspeed. CFI pitched nose down and added full power 5 seconds before impact to cushion impact. No injury or major impact damage occurred. Contributing factors: 1) student pilot logged less than 10 hours in preceding 1 yr, with last flight being 3 weeks prior to occurrence. 2) strong wind (15-20 KTS) sheared to between 5-10 KTS at low altitude within 50' of ground. 3) student agreed to, but did ot take action to increase airspeed after being advised by CFI. Human factors: 1) student did not take appropriate action in sufficient time to avoid hard impact. 2) CFI did not assume control of aircraft in sufficient time to avoid impact. 3) student-CFI communication ambiguous in both directions, delaying decision of CFI to effect recovery.

Title: GUSTY SURFACE WINDS AND INEXPERIENCE SPI, RESULT IN HARD LNDG.

Narrative: ACFT IMPACTED RWY 26 AT N70 AFTER ONSET OF STALL OCCURRED ON FINAL APCH. STUDENT PLT HAD REDUCED PWR TO IDLE AND EXTENDED FULL FLAPS DUES OT HIGH ALT (200' AGL) AT RWY THRESHOLD. STUDENT FAILED TO PITCH NOSE DOWN TO MAINTAIN RECOMMENDED 85 MPH APCH AIRSPD. CFI PITCHED NOSE DOWN AND ADDED FULL PWR 5 SECS BEFORE IMPACT TO CUSHION IMPACT. NO INJURY OR MAJOR IMPACT DAMAGE OCCURRED. CONTRIBUTING FACTORS: 1) STUDENT PLT LOGGED LESS THAN 10 HRS IN PRECEDING 1 YR, WITH LAST FLT BEING 3 WKS PRIOR TO OCCURRENCE. 2) STRONG WIND (15-20 KTS) SHEARED TO BTWN 5-10 KTS AT LOW ALT WITHIN 50' OF GND. 3) STUDENT AGREED TO, BUT DID OT TAKE ACTION TO INCREASE AIRSPD AFTER BEING ADVISED BY CFI. HUMAN FACTORS: 1) STUDENT DID NOT TAKE APPROPRIATE ACTION IN SUFFICIENT TIME TO AVOID HARD IMPACT. 2) CFI DID NOT ASSUME CTL OF ACFT IN SUFFICIENT TIME TO AVOID IMPACT. 3) STUDENT-CFI COM AMBIGUOUS IN BOTH DIRECTIONS, DELAYING DECISION OF CFI TO EFFECT RECOVERY.
