For the record, there are a number of countries worldwide that exhibit the same restricted cultural legacy. For example, there is also a High Power Distance ratio in a number Latin American and African countries [2]. See, for example, details of the crash of Colombian Avianca Flight 52 [3].
Whether this is a factor _in this particular incident_ is of course for the authorities to decide. Considering the provenance of this airline as being from a high power distance ratio country I felt this information might be relevant or at least of interest to others.
