B738, Mumbai India, 2018

Summary

On 10 July 2018, a Boeing 737-800 marginally overran the wet landing runway at Mumbai after the no 1 engine thrust reverser failed to deploy when full reverse was selected after a late touchdown following a stabilised ILS approach. The Investigation found that the overrun was the result of touchdown with almost 40% of the runway behind the aircraft followed by the failure of normal thrust reverser deployment when attempted due to a failed actuator in one of the reversers. The prevailing moderate rain and the likelihood that dynamic aquaplaning had occurred were identified as contributory.

Description

On 10 July 2018, a Boeing 737-800 (VT-AXT) being operated by Air India Express on a scheduled domestic passenger flight from Vijayawada to Mumbai as IX213 marginally overran the wet landing runway 14 at destination after a stabilised approach was followed by a deep landing and the failure of one of the thrust reversers to deploy. With assistance, the aircraft, which was undamaged apart from tyre wear attributable to excessive braking and had remained on a paved surface just 5 metres beyond the end of the runway, was able to taxi to its assigned parking gate for passenger disembarkation.

Investigation

An Investigation was carried out by the Indian DGCA Directorate of Air Safety in accordance with the Aircraft (Investigation of Accidents and Incidents) Rules 2017. Data from both the CVR and the FDR were successfully downloaded and together enabled a detailed reconstruction of the flight.
