(-23) The pilot, a CFI at inbound aviation, departed runway 13R at rhv, with a student, to practice flight in the airport traffic pattern. After takeoff, at approx. 200 feet, the pilot observed the engine was not developing full power. She said she attempted to clear the engine with carburetor heat, and followed the emergency checklist. At 500 feet, with approximately 1600 RPM, the pilot said she declared an emergency and turned back to the airport. She said she landed on the opposite direction runway (runway 31R). She said carburetor heat remained on throughout the approach and landing. She said she followed normal landing procedures, and used full flaps for landing. She said she landed long and stopped just past the landing threshold, with the nosewheel off the pavement. The aircraft was not damaged and there were no injuries. The pilot said inbound aviation maintenance personnel told her that two (2) fouled spark plugs were noted after the incident, and carb ice may have occurred. No further action is required. This closes the investigation.
