I was struck by the news of this deadly plane crash on 20 Dec 2018 which claimed 8 lives and apparently is not investigated as the plane and its potential survivors were not even searched for:
A Gomair Antonov AN-26 on behalf Central Electoral National Independent Commission (CENI), registration 9S-AGB performing a cargo flight from Tshikapa to Kinshasa Ndjili (DR Congo) with 7 or 8 crew and election materials, was cleared to descend to 5000 feet on approach to Ndjili's runway 06 when the aircraft went missing about 20nm short of Kinshasa's runway 06 at about 10:00L (09:00Z). The aircraft was found about 24 hours later in hilly terrain (peaks rising up to 700 meters/2300 feet MSL) about 19nm before runway 06. Local Congolese media report Authorities did not launch a search for the aircraft. The aircraft was found by random chance by a local, who reported 8 bodies in the wreckage. (source)
Aren't countries bound at least (if nothing else) by international treaties and ICAO regulations to
- perform SAR operations for missing aircraft lost in their sovereign airspace
- and investigate the cause of the accident ?
In which countries can deadly plane crashes lack either one or both ?
Q (from a comment below): "There are countries which may not have the resources to conduct their own investigation of a crash and may request assistance from another country."
A: Good point. Countries unequipped to handle S&R or crash investigations can voluntarily outsource either one or both to other countries. For the pupose of this question, a crash in country X investigated by country X or Y does equally count as being investigated, so this is NOT what my question is about. I'm asking about dead passengers searched for by NOBODY and crashes investigated by NOBODY.
