According to PTV News and PTV World, Safety Investigation Board (SIB) began investigation work meetings today and took custody of aircraft's wreckage pieces.

SIB has asked Pakistan CAA to provide record of communication between ATC & PK-661, and PIA has been asked to provide technical/maintenance log book/record of ill-fated ATR 42-500 (AP-BHO).

So far, SIB has not released any preliminary investigation report.

The crash site was also visited by forensic teams today. Forensic investigators belonging to PAF, CAA and PIA photographed crash site and also collected important pieces of wreckage.

PIA ATR 42-500 (AP-BHO) approaching Jinnah International Air Port (JIAP) - Karachi Runway 25L photographed by Hammad Hassan Mahmood some years ago. The ATR was named "Hasanabdal - The Gurdwara Glory" and sported Punjab Province tail design as part of Pakistan province tails livery applied on PIA aircraft at that time.

ATR team to visit Pakistan to take part in PK-661 crash investigation. Video grab apparently shows PIA team taking part in investigation process/arriving at crash site.

French Embassy in Pakistan has assured support in investigation process.

On December 9, PIA resumed flights to/from Chitral, according to news reports.

Today CEO PIA Bernd Hildenbrand visited the crash site where he placed flowers and observed a moment of silence, according to news sources.


The investigators at crash site today also recorded statements of locals who witnessed the crash.

I think after the removal of wreckage, a memorial for flight 661 should be built at or near the crash site. Maybe a simple wall or tablets of stone with engraved names of all 47 victims.

AP-BHO engine propeller?


AP-BHO wing section or horizontal stabiliser?

Some device/component removed and secured by authorities from tail section of the aircraft probably on the day of crash.

There are some speculations that ill-fated flight PK 661 suffered 'uncontained engine failure' which resulted in damage to wing and consequently aircraft fell downwards. Well this is a high possibility. This picture is about month and a half old. This Ameircan Airlines flight at Chicago suffered same 'uncontained engine failure' and see what happened to the wing. This aircraft was quite lucky that engine failure occured just prior to landing. PK 661 was probably unlucky it happened at somewhere around 15000 ft and had no chance

While no one should jump to conclusions without access to all the details surrounding the accident, I have a hunch that the Hamilton Sundstrand 6-bladed 568F prop on this ATR 42-500 was poorly maintained by PIA Engineering.

PIA is not qualified to maintain these propellers and Hamilton Sundstrand, the manufacturer (now known as UTC), had warned them to this effect in writing in the recent past.

Poor maintenance and modifications to the prop by using non-standard parts and procedures by PIA could have possibly resulted in a catastrophic engine failure similar to that experienced by Atlantic Southeast Airlines (ASA) Flight 529. You can learn more about ASA 529 from the links below:

Possible hidden structural damage to AP-BHO from the Lahore incident in 2009 and non-standard repair work that followed could have resulted in structural weaknesses that could have led to major structural failure of the left wing and surrounding structures as a result of a possible catastrophic prop failure.

Mubashir Luqman raised similar point in his program. I am afraid if this turns out to be true, it wont be expressed publicly that this malpractice is the reason. Instead they will blame the usual, the gone: the pilot

Anyone who's watched Khara Sach program on PIA knows very well how the ATRs are being maintained by PIA, which is shabby maintenance which is not certified or authorized by the manufacturer.
I think people should stop flying the ATRs until or unless PIA gets them serviced abroad at a certified facility for repair/maintenance for ATRs.

It's really difficult to bear that pretty much nothing substantial can be expected from Pakistani SIB,PIA,CAA etc because of their vested interests in covering for each other. It would've been better to get NTSB do the whole investigation at least the truth would come out. Does the SIB even have all the tools and/or resources and technology/knowledge to do such investigations. Even the old reports look so unprofessional upon completion.

Some eyewitnesses said that the aircraft was already on fire before hitting hilly terrain.

In case of disintegrating/on fire engine number 1/port side wing, the investigators must have widened their area of search to find any debris of the aircraft under its flight path before impact with ground point where the main wreckage is lying.
