2007 Cessna 152II accident at Cascais (CS-DDP)

Flight and accident sequence On 23 October 2007, a Cessna 152II registered CS-DDP, operated by Escola de Aviação Aerocondor, departed runway 35 at Aeródromo Municipal de Cascais – Tires for an instructional visual-flight-rules trip to Coimbra. The flight plan listed a route via CROCA, ERICE, FTM, and LPCO, with LPVZ as the alternate. After reaching Cabo da Roca, the pilot-instructor cancelled the trip and returned to Cascais for circuit training. Following two uneventful touch-and-go landings, the student pilot made a final approach to runway 35. At 09:46 UTC, the main wheels touched down at about 65 knots. When the nose wheel landed, the aircraft began to deviate to the left, a tendency the pilot could not correct. The aircraft then left the runway surface, describing a path at roughly 35 degrees to the runway axis, and overturned after the nose wheel had moved about 4.50 metres on adjacent ground. ## People, aircraft, and conditions The two-person crew consisted of a 22-year-old Italian pilot-instructor and a 26-year-old Portuguese student pilot. Both held valid Class 1 medical certificates and left the aircraft without injury. The aircraft sustained substantial damage, including a bent fuselage structure, deformed left horizontal stabilizer tip and wings, a twisted nose gear, damaged vertical fin and rudder, destroyed upper beacon and communication antennas, twisted propeller blades, and a dented spinner. Light grooves were made on the runway by the dragged nose-wheel rim. Meteorological data from LPPT indicated generally light winds and good visibility; at Cascais, QNH was 1021 hPa and the wind was calm at the time of landing. The aircraft was a 1983 Cessna 152II with a Lycoming O-235-N2C engine and McCauley propeller, registered as a training aircraft with valid documentation. The report was issued by Portugal's GPIAA under accident investigation report number 23/ACCID/2007.
