A320, vicinity Naha Okinawa Japan, 2014

Summary

On 28 April 2014, an Airbus A320 making a precision radar approach at Naha in IMC began descent from 1,000 feet QNH at 6nm from touchdown with the autopilot engaged and continued it until successive EGPWS 'PULL UP' Warnings occurred soon after the radar controller had advised four miles from touchdown. Minimum recorded radio height was 242 feet with neither the sea nor the runway in sight. The Investigation noted ineffective alerting by the First Officer, the radar controller's failure to notice the error until just before the EGPWS Warnings and the absence of MSAW annunciations at the controller's position.

Description

On 28 April 2014, an Airbus A320 (JA802P) being operated by Peach Aviation, on a scheduled domestic passenger flight from New Ishigaki to Naha as MM 252 made a go around from its PAR approach to destination after descending into close proximity with the sea surface whilst still approximately 3½ nm from the airport in day IMC. Repositioning to a further approach from which a landing was made was without further event. There were no injuries to the 53 occupants.

Investigation

An Investigation was carried out by the Japan Transport Safety Board (JTSB) and commenced the day after the occurrence. Data from the FDR were successfully downloaded but relevant data on the CVR had been overwritten. Data stored in the NVM of the EGPWS Unit was recovered and recorded ATC data was also available.
