## Analysis

DURING AN INSTRUCTIONAL FLT THE STUDENT PLT, WHO HAD A TOTAL OF 5 HRS OF FLT TIME, ATTEMPTED TO LAND WITH THE FLAPS EXTENDED TO THE 20 DEG POSITION. THE ACFT BALLOONED, & THE CFI TOOK CONTROL & ELECTED TO COMPLETE THE LANDING. INSUFFICIENT RWY REMAINED & THE ACFT OVERRAN ITS END, TRAVERSED A DRAINAGE DITCH AND COLLIDED WITH A FENCE. THE CFI REPORTED THAT, MECHANICALLY, THE ACFT WAS IN PROPER WORKING CONDITION. HE ALSO STATED THAT HE WAS UNAWARE OF THE EFFECT REMOVING THE 20 DEG OF FLAPS WOULD HAVE ON THE ACFT'S STOPPING DISTANCE, SO HE LEFT THE FLAPS EXTENDED.
