B734, Timbuktu Mali, 2017

Summary

On 5 May 2017, a Boeing 737-400 made a visual approach to Timbuktu and slightly overran the end of the 2,170 metre-long runway into soft ground causing one of the engines to ingest significant quantities of damaging debris. The Investigation found that the landing had been made with a significantly greater than permitted tailwind component but that nevertheless had the maximum braking briefed been used, the unfactored landing distance required would have been well within that available. The preceding approach was found to have been comprehensively unstable throughout with no call for or intent to make a go around.

Description

On 5 May 2017, a Boeing 737-400 (JY-JAP) being operated by Jordan Aviation on a scheduled domestic passenger flight from Bamako to Timbuktu as JAV 7843 departed the end of the destination runway after a fast and slightly late touchdown off a visual daylight approach and insufficient deceleration thereafter to exit as intended at the end of the runway. None of the occupants were injured but the aircraft’s left engine sustained internal damage to all its fan blades due to ingestion of multiple pieces of small gravel from the soft ground area where it ended up.

Investigation

An Investigation was carried out by the Civil Aviation Regulatory Commission of the State of the Operator, Jordan. Data from the SSFDR was downloaded and used to inform the Investigation but it was found that relevant data from the SSCVR had been erased. It was not determined whether this erasure was intentional or not.
