Narrative:

Presolo training flight (decision not to solo student because of winds/aeronautical club restrictions). Wind reports from WX sources did not jibe with windsocks (6-8 KTS reported versus 10-15 KTS observed). Departed adw on a VFR flight plan, hyde departure. Flew 5-6 mi south of W32 to warm-up with turns and slow flight. Student is a strong performer. Return to W32, enter traffic pattern (approximately 10 degree wca to correct drift, parallel runway). First approach developing nicely despite gusty winds. Aircraft drifted left of centerline approaching threshold, nose slightly left of center. Approximately 10 ft, I commanded 'go around.' student retarded throttle instead of increasing power. Rapid descent to runway ('firm' landing) -- then student applies full throttle and full brakes. We are skidding off the left edge -- I manage to force the rudder/steering left to miss a runway light, continue our deceleration (student now relinquishes controls to me) in the sod and up a rise to a parking area. Happens very quickly. We secure airplane and inspect for damage. Chain of custody: probably a bad decision to train in gusty winds. (Student thinks I saved him a bad experience later). I should have kept a closer guard on the controls -- anticipating potential confusion over the threshold. The student doesn't recall my 'go around' call. But his response is typically 'student' -- 'whoops! Did I do that?' if I had kept the aircraft airborne, there'd be no testimonials (rubber tracks and grooves in the grass) to wince about. I think I resolved the 'anti- skid off' problem such that both of us can redefine some 'edges of the envelope(south).' resolve: training is a good idea; keep conditions conservative; embellish with 'demonstrations' hands on or nearby; provisional planning -- anything can happen to me.

Title: STUDENT PLT LOST DIRECTIONAL CTL OF ACFT DURING A LNDG IN GUSTY XWINDS RESULTING IN THE ACFT DEPARTING THE SIDE OF THE RWY. THIS WAS A DUAL INSTRUCTION TRAINING FLT.

Narrative: PRESOLO TRAINING FLT (DECISION NOT TO SOLO STUDENT BECAUSE OF WINDS/AERO CLUB RESTRICTIONS). WIND RPTS FROM WX SOURCES DID NOT JIBE WITH WINDSOCKS (6-8 KTS RPTED VERSUS 10-15 KTS OBSERVED). DEPARTED ADW ON A VFR FLT PLAN, HYDE DEP. FLEW 5-6 MI S OF W32 TO WARM-UP WITH TURNS AND SLOW FLT. STUDENT IS A STRONG PERFORMER. RETURN TO W32, ENTER TFC PATTERN (APPROX 10 DEG WCA TO CORRECT DRIFT, PARALLEL RWY). FIRST APCH DEVELOPING NICELY DESPITE GUSTY WINDS. ACFT DRIFTED L OF CTRLINE APCHING THRESHOLD, NOSE SLIGHTLY L OF CTR. APPROX 10 FT, I COMMANDED 'GAR.' STUDENT RETARDED THROTTLE INSTEAD OF INCREASING PWR. RAPID DSCNT TO RWY ('FIRM' LNDG) -- THEN STUDENT APPLIES FULL THROTTLE AND FULL BRAKES. WE ARE SKIDDING OFF THE L EDGE -- I MANAGE TO FORCE THE RUDDER/STEERING L TO MISS A RWY LIGHT, CONTINUE OUR DECELERATION (STUDENT NOW RELINQUISHES CTLS TO ME) IN THE SOD AND UP A RISE TO A PARKING AREA. HAPPENS VERY QUICKLY. WE SECURE AIRPLANE AND INSPECT FOR DAMAGE. CHAIN OF CUSTODY: PROBABLY A BAD DECISION TO TRAIN IN GUSTY WINDS. (STUDENT THINKS I SAVED HIM A BAD EXPERIENCE LATER). I SHOULD HAVE KEPT A CLOSER GUARD ON THE CTLS -- ANTICIPATING POTENTIAL CONFUSION OVER THE THRESHOLD. THE STUDENT DOESN'T RECALL MY 'GAR' CALL. BUT HIS RESPONSE IS TYPICALLY 'STUDENT' -- 'WHOOPS! DID I DO THAT?' IF I HAD KEPT THE ACFT AIRBORNE, THERE'D BE NO TESTIMONIALS (RUBBER TRACKS AND GROOVES IN THE GRASS) TO WINCE ABOUT. I THINK I RESOLVED THE 'ANTI- SKID OFF' PROBLEM SUCH THAT BOTH OF US CAN REDEFINE SOME 'EDGES OF THE ENVELOPE(S).' RESOLVE: TRAINING IS A GOOD IDEA; KEEP CONDITIONS CONSERVATIVE; EMBELLISH WITH 'DEMONSTRATIONS' HANDS ON OR NEARBY; PROVISIONAL PLANNING -- ANYTHING CAN HAPPEN TO ME.
