Pakistan Airlines Pilots' Association spokesperson Tariq Yahya, while speaking on Geo News, said:
"Communications show that the plane did not have power at the end and was gliding and couldn't make it to the runway."
He said that it didn't have power when it was asked to climb to 3,000 feet.
He said these are "only are assumptions and we will not know the exact cause until we find the black box."
Yahya said pilots are handed a "technical log book" which is filled out by engineers and is a declaration that the plane is safe to fly. The pilot then independently reviews all the various flight functions on board the plane.
The spokesperson also remarked that there is a "very poor safety culture in place when it comes to the civil aviation authority as well as the PIA safety department" — an issue raised by PALPA as well, and which has only deteriorated over time.
He said that the construction of tall buildings near an airport is a violation of Civil Aviation Authority rules.
An Army Urban Search and Rescue Team has been dispatched via a C-130 military plane from Rawalpindi.
According to Geo News, families located at the crash site are being vacated from the area.
