Jet Airways flight 9W2423 was a scheduled service from Delhi to Varanasi and Khajuraho. The aircraft departed from Varanasi Airport at 12:45 local time and the flight was normal till touch down on runway 19 on Khajuraho Airport. The captain was pilot flying and co-pilot was carrying out duty of Pilot Monitoring.

At touchdown the aircraft pitch was 4.39° with a vertical deceleration of 1.65G and a touchdown speed of 120 kts (Vref -4kts). During landing roll, 15 seconds after touchdown, at speed 36 knots the left main landing gear aft trunnion pin broke and the aircraft started deviating to the left of the center line. The aircraft came to stop on the runway with damage to the left hand main landing gear and resting on the no.1 engine, nose and right hand landing gear. Hydraulic fluid spillage occurred due to damage to the main landing gear.
An emergency evacuation was carried out on the runway. All four main doors, escape slides and four emergency over wing exits were opened. However, the passengers used two escape slides (L1 and R1) for evacuation. One cabin crew member received minor injuries (bruises) during evacuation.
The runway was closed after the accident as aircraft became disabled on the runway. The disabled aircraft was removed from the runway at 16:45 hours.

Probable Cause:

PROBABLE CAUSE OF THE ACCIDENT: "The LH Aft landing Gear trunnion pin failed due to overload following fatigue growth. Crack initiation was in the heat affected area where excessive grinding was done at the time of overhaul. Initial crack growth is charterized by intergranular cracking (assisted by hydrogen embrittlement mechanism) until fatigue took over."
