Flight History
On 21 November 2005, a Saab 2000, registration CS-TLK, was operating a passenger flight from Valencia to Lisbon with two pilots, two cabin crew, and ten passengers. The flight was uneventful until the approach to Lisbon.
Approach and Landing
The crew received ATIS information indicating runway 03 in use, with an ILS approach. Wind was from 130 degrees at 18 kts gusting to 29 kts. Visibility was 10 km, with light rain showers and few cumulonimbus clouds.
During the approach, the pilot deviated right to avoid a stationary cumulonimbus near the IAF (Caparica NDB), shortening the distance to the glide slope and causing the aircraft to be high. The pilot requested descent to 2,500 ft and was cleared for a visual approach to runway 03.
At 1,746 ft, the pilot disconnected the autopilot. The aircraft remained above the glide slope. To reduce altitude, the pilot pitched down to 11 degrees, increasing speed to 174 kts IAS. Several sink rate and pull-up warnings occurred. The co-pilot suggested a go-around, but the commander continued, considering the runway long enough.
The first touchdown was with the nose wheel for 1-2 seconds at 146 kts IAS. The nose wheel then lifted off, and the aircraft floated down the runway, touching down again near exit U5 at 109 kts ground speed. The runway was wet from light rain. Wind at landing was from 140 degrees at 27 kts, a strong tailwind from the right.
Aftermath
After touchdown, the pilot applied brakes but the aircraft did not slow effectively. It exited the runway via taxiway S4. Subsequently, it was found that all four main landing gear tyres had burst. The incident was reported to the GPIAA by NAV and the operator. No injuries were reported. The aircraft sustained damage to the tyres.
