Accident Sequence
On 11 January 2004 at 16:37 UTC, a Cessna 152, registration CS-DDW, operated by Escola de Aviação Aerocondor, S.A., was conducting a training flight at Cascais Municipal Aerodrome. The student pilot, the sole occupant, had just performed a normal landing on runway 35 after a stabilized approach, touching down before the 1000-foot mark, approximately 150 meters past the threshold. Immediately after touchdown, while the aircraft was still moving, the pilot decided to apply power for a touch-and-go.
During acceleration, the torque effect of the engine caused the aircraft to veer left. The pilot was unable to counteract this movement. He immediately reduced power and attempted to stop the aircraft within the runway, but without success. The aircraft continued off the runway at an angle of about 45 degrees to the runway axis, traveling over wet grass before coming to rest in a drainage ditch known as Ribeira das Marianas.

The aircraft was a Cessna 152, a high-wing monoplane with fixed tricycle landing gear. It was equipped with a Lycoming O-235-L2C engine and a McCauley fixed-pitch propeller. The student pilot was 23 years old and held a valid student pilot authorization.
Weather Conditions
Weather at the time was good, with moderate wind from 350° at 10 knots, gusting to 15-17 knots. Few clouds were present at approximately 2000 feet, visibility was greater than 10 km, temperature was 20°C, and QNH was 1027 hPa.
Damage
The aircraft sustained serious damage to the nose landing gear, engine mount, fuselage structure (particularly on the left side below the door), propeller (one blade bent 90 degrees), left wing tip, and tail cone.
