2016-02-27 IndiGo Airbus A320 below minimum height near Jaipur

Narrative

When the A320 approached Jaipur when it descended below the approach path until an altitude alert prevent the flight from hitting a multi storey house. All on board remained safe.

IndiGo flight 6E 237 was on a Localizer DME (requires manual vertical guidance by pilot) approach to runway 27 at  Jaipur Airport in hazy conditions.

About a minute away from landing, an automatied warning from the EGPWS (Enhanced Ground Proximity Warning System) chimed indicating imminent risk of ground collision.

EGPWS: „Obstacle, Obstacle, Pull Up!“

 

At an altitude of 480 ft AGL (above ground level), the pilots initiated a go-around within two seconds after the alarm and climbed away safely. The aircraft circled for another approach where they made a safe landing.

Indian investigators of DGAC revealed the A320 missed a 340 ft. tall multi-storey building by only around 100 feet (30 Meters).

The reason for the premature descend to Jaipur and the continuation of the descent below the minimum descision altitude (MDA) of 600 feet was not officially reported.

However, it was concluded the pilots mistook the lines of streets lights as the pattern for the approach lights of runway 27.

This is incident is understood to be the first ‘save’ with the EGPWS ‘obstacle’ mode.

Both pilots have been grounded for the course of the investigation.
