Did the pilot touch down on 1st attempt?
To get the answer we need to look at this data of flight altitude which has some clues.
Which means his gears system was fine.
But when his engines gave up the plane stalled, which can also be seen in the video.
Having said that I’m not ruling on what happened with AP-BLD.
The landing gears failed to deploy? Or they were never deployed?
CCTV of runway definitely can solve this.
But those engines are writing on the wall.
