Narrative:
A Boeing 737-4Y0 of Trigana Air Service suffered a runway excursion on landing at Jakarta-Halim Perdana Kusuma Airport (HLP), Indonesia.
The aircraft departed HLP at 10:53 hours local time (03:53 UTC), bound for Makassar. Two minutes later the flight reported the failure of engine no.2. The flight crew then contacted ATC, requesting a hold. After holding for 19 minutes, the flight requested an ILS approach to runway 24 at HLP.
During landing the aircraft veered off the right side of the runway, coming to rest in the grass perpendicular to the runway. A video of the landing suggests the right-hand main gear (partly) collapsed.

The aircraft was dismantled on site and removed.
