Not related to covid shutdown as this plane had 7 prior flights to this accident
The plane had a alarm go off warning that wheels were not locked properly but ignored it as a false alarm during 1st attempt.
On touchdown, the physical feedback indicated to him that the wheels were actually not down and he initiated abort landing.
But the engines had impacted the runway by that time and both engines had leaked lubrication oil/hydraulic oil due to damage.
He managed to reach 5000 ft for another attempt at landing but the engines gave way a few seconds before the crash.
His last moment mayday and normal tone indicates that he was unaware that the plane might not make it.
The 3 to 4 stories houses near the airport probably caught the bottom of the plane and he realized the danger very late.
Now since no formal investigation reports of the last 3 crashes in Pakistan in the last 10 years have been released , I don't have high Hopes of any transparency in this accident.
If he scrapped the bottom of the plane, the ATC or other airport officials should have commented by now on the sparks generated or damage to the runway . But nothing from them.
Problem is that many institutions try to mitigate reputation damage and the reports are censored or biased.
