A circuit board which could be part of a homing radar head 9E50M1 part of a BUK 9m38 series missile was recently found at the MH17 crash site. Twitter user Slozhny reported the finding here. Internet forum mh17.webtalk.ru reported at September 11 2016 about the found debris.
While this is an interesting find, we have to be carefull. Is it indeed a part of a missile? Why was this part not recovered? Has it been at the crashsite all the time? Was it planted? There has been so much misinformation on MH17.
Two elements (integrated circuits) are labeled as mil-spec and have been made in Sep 1986 and Dec 1985.
The part was found about 2,5 km north of the village of Petropavlivka.
The location of the circuit board inside the homing radar head is indicated by the red arrow in the picture below.
Some of the chips shows a date. More close-up photos of the board are here.
Besides the circuit board some parts of the aircraft were found. Clearly visible are parts of what could be the engine nacelle. The Rolls Royce logo can be seen on some of the parts.
This metal piece (161 g) was also discovered at the same site. Nonmagnetic, except the bolt and nut.
