Analysis

Near the completion of a dual instructional flt with a pre-solo student, the CFI followed the procedures recommended in the aim 7 & announced his Cessna acft's position over the CTAF stating his intentions & identifying his location on the 45 deg. Entry & downwind legs. The CFI failed to transmit his position on the final approach leg, & failed to observe a Piper acft on its takeoff roll. The plt in the Piper acft, who was preparing to depart, failed to announce his intentions & position on the taxiway/rwy, failed to observe the inbnd Cessna & rence failed to give that acft the right-of-way as required. As the Piper was being rotated for takeoff the Cessna descended onto & collided with it. The Piper plt aborted his takeoff, & the Cessna landed withour further mishap. Both plts reported that the presence of tall trees located adjacent to the rwy's approach had obstructed their vision.
