What happened
On October 8, 2015, a Cessna 680 aircraft, registration PP-BST, was performing a flight from Campo de Marte Airport (SBMT) to Jacarepaguá - Roberto Marinho Airport (SBJR) in Rio de Janeiro. The flight was carrying two pilots and one passenger.
During the landing phase on runway 02, the aircraft performed a long touchdown. The aircraft subsequently overran the end of the runway by 6 meters. There were no injuries to the crew or the passenger, and the aircraft sustained no damage.
The investigation
CENIPA investigators analyzed the flight sequence using Cockpit Voice Recorder (CVR) data and meteorological reports. The investigation established that the aircraft was operating within weight and balance limits and that all required certifications and medical certificates for the crew were valid. All navigation aids at the aerodrome were functioning normally.
Analysis of the CVR revealed that several terrain and pull-up warnings were triggered during the final approach, indicating that the aircraft was flying at an altitude below the planned glide path. The crew noted the presence of a slight tailwind component and expressed concern regarding the remaining runway length. Calculations showed that while the required landing distance was approximately 841 meters—within the 900-meter available—the margin was slim, utilizing over 93% of the available runway.
Findings
- Inadequate control inputs, which resulted in an unstabilized approach with a lower-than-normal glide path.
- Pilot judgment, specifically the failure to execute a go-around despite the unstabilized approach and the presence of a tailwind component.
- The aircraft performed a long touchdown, which delayed the effective use of braking.
- The approach angle was too low, necessitating increased power to compensate for the pitch attitude, which contributed to the tendency to float over the runway.
