Looks like the crew did not extend landing gear on first approach. Attempted to land with gear up. Went around and suffered 2 engine failures. SAD.
Juan Browne (Blancolirio) does a good job and analysis of the crash based on eyewitness photos of the damage in flight.
Watch the video.

This is a tragic story and you can add another reason. Why we are not flying in anytime soon. Pilot error.

Sounds like the first approach was with the gear retracted and the airplane contacted the runway on the engine nacelles, That was the likely cause of the dual engine failure as the fuel pumps, engine controls and other necessary engine equipments are located on the bottom of the engines. When they were destroyed or damaged on the first approach, engine shutdown was inevitable.

Juan Browne (Blancolirio) provides a visual explanation of the gearbox accessory drive that was more than likely damaged. He also provides some explanation as to the "what may have occurred' . He does not think they forget to drop the gear, but rather attempted a go around and then settled back down and struck the runway.

Also has some footage of a 747 engine strike to demonstrate how this can occur during a heavy crosswind.

I found this on an Aviation site I frequent.

If Accurate, it shows them descending from 10000 feet to 2000 feet in about 2.5 minutes. Such a flight path is absurd for a commercial airliner except in an emergency. The red line shows a typical stabilized approach that is the standard for any airliner. The steep approach of the flight is a recipe for disaster.

If this sort of thing interests you, the Smithsonian Channel has a series called Air Disasters which documents the cause analysis that takes place after crashes and incidents. Mechanical failure, erroneous programming, inadequate training, improperly thought out procedures, human error, etc. are all considered. The dedication of the investigators and lengths they go to in their investigations is amazing. The result is many changes brought about in the industry to prevent (or reduce the likelihood at least) of recurrence.

I watch that documentary series. DW gets upset when I view.
Passenger aviation travel in the US has a stellar record of safety.
Safer then driving down the street in you personal vehicle.

I like that show as well. I actually think it is a great show for someone who is nervous about flying to watch. You soon realize that with almost every accident, it was a series of several things / decisions that all went wrong that resulted in the accident, and not just a single failure. Also, as a result of the investigations, most accidents cause changes to safety procedures or modifications to existing equipment so the same thing will not happen again.

Back in the day, I was involved in a number of aircraft accident investigations for the USAF. As you noted there can be a series of separate errors in any accident, design, maintenance or Pilot decisions are typical. Any one can usually be handled but if they line up, an unfortunate result occurs.

Pure speculation on my part but this could be one such case. First, the steep “abnormal” descent. Second possible runway misalignment. Third, distraction because of the first two and then failure to lower the gear or early retraction for a go around. Fourth, Going around after the plane touched down on the engines.

Again, pure speculation on my part but a different decision to go around earlier after starting the descent or go around after not being lined up on the correct runway, either of which would have broken the chain. Other possibilities are the Air Traffic Control delaying clearance to descend sooner resulting in the steep descent, malfunction of the gear mechanisms, other mechanical or software failures, or some unknown problem.

Fortunately, the “black boxes” have been recovered and will answer many questions. https://www.ndtv.com/world-news/pakistan-plane-crash-pilots-role-air-traffic-teams-conduct-under-probe-2234429

I like watching that show as well. However, I try to avoid it right before I am to travel.

Juan Browne -- Blancolirio is really deep into this incident. BTW he was a C-141 driver at Travis in 89. I was a Crew Chief USAF C-141 McGuire 80-84. Now he is a pilot for AA.

Here is a live stream discussion with another YouTube pilot based in Barcelona, Spain.

Looks like he is using the same reference for flight data
