Regarding incident 8:
Last week, the aircraft was heard radio-ing Fatmawati Tower (Bengkulu airport) asking if a pushback truck was available at the airport. The airport had no pushback trucks, so the crew asked "which runway direction would give (him) the longest distance to the taxiway intersection (next to the apron). A witness then photographed why the aircraft asked for the information, it lost its HYD A pressure resulting in no nosewheel steering.
