Today I found another piece of wreckage of MH17 not seen on photos before. The part seems to be have been located near the first door on the lefthand side of the aircraft. This part is very close to the cockpit.
If this part was located close to the cockpit it could provide important information about the location where the BUK missile exploded.
The photo was found in this thread at mh17.webtalk.ru in a post made at August 24, 2016.
The part possibly was found near Petropavlivka. This area was under heavy fighting for months which prevented the recovery of many aircraft debris. However other debris which fell near Petropavlivka were recovered by DSB. It is unknown if this particular part was taken away by someone before DSB could recover it. For sure the area was controlled by the separatists.
DSB mentioned this part in the final report and located in near Petropavlivka
The DSB final report states this part was not recovered.
This map shows the location where wreckage was located. The green area was searched by the international recovery team. The orange area is unsafe because of fightings. The separatists did not allow the recovery team to search in the areas indicated by red.
This piece of the wreckage is located roughly between the orange and red area.
The likely location of this part is indicated in blue.
The diagram at page 115 of the DSB final report suggest the above photo was used by DSB to establish where fracture lines in the fuselage were located. Thanks Wind Tunnel Man for the comment. Line U1-B1 is the edge of the debris seen on the photo.
The photo was first seen in a Chinese tv programme about MH17. Besides webtalk.ru the photo cannot be found on other websites. So I guess a Chinese photographer made the photo. As the photographer did not work for European or American agencies the photo was not published in Western media.
appendix X of the Dutch Safety Board shows the parts that were recovered. So far I am not able to locate this part.
This photo shows door 2 on the lefthand side. For a complete overview of all photographed wreckage parts see this.
