The pilot-in-command's/flight instructor failure to communicate his intentions with the student pilot to effect a positive transfer of the flight controls, and improper handling of the airplane on landing roll out, resulting in an on ground collision with a fence.

Analysis

The student pilot was making a full stop landing with the flight instructor following through on the flight controls. On landing, the airplane bounced and yawed to the right. The student pilot and flight instructor applied left rudder and brakes, and the airplane started to skid sideways. The flight instructor took control of the airplane without informing the student pilot. The student pilot increased the throttle and the flight instructor decreased the power to the idle position. The airplane continued through the overrun and collided with a fence.

Factual narrative

On August 17, 1993, at about 0900 eastern daylight time, a Grumman AA-5B, N11LT, registered to 11 Lima Tango Inc., operating as a 14 CFR Part 91 instructional flight crashed on landing. The airplane sustained substantial damage. Neither the commercial pilot/flight instructor or student pilot were injured. Visual meteorological conditions prevailed and no flight plan was filed. The flight originated about 30 minutes before the accident.

The flight instructor stated to the NTSB investigator-in-charge that the student pilot was making a full flap landing to runway 09, and that he was following through on the flight controls with the student pilot. On landing the airplane bounced and yawed to the right. Both he and the student pilot applied left rudder and brakes. The airplane started to skid sideways and he took control of the airplane without informing the student pilot. The student pilot increased power and he decreased power to the idle position. The airplane continued through the overrun and collided with a fence.
