On 18 March 2019, a Bombardier Challenger 300 had just touched down at Subang when it collided with an unseen and apparently unlit vehicle destroying it and critically injuring its occupant. Significant left wing leading edge damage was then found. The destroyed vehicle and another one had been cleared onto the runway by ATC for routine runway maintenance purposes by a single controller who then failed to tell another colleague taking over that the runway was occupied. Use of single controller position manning was non-standard and airside vehicle and aircraft communications were routinely using different communication channels preventing situation awareness.
