Do not blame to weather only…. There is other reason too. Nepali aircraft and helicopter crashed because of these… Nepali corrupted business brought expires and out-dated aircraft and helicopter from desperate economy crisis countries like ex-Russia or Russian. Which should not use in anyplace because any time these kind of expire aircraft can crash. Beyond capacity, Usually Nepali government high official use beaurocratic force to fly bad condition and under capacity. When Nepali government official need to go somewhere they forcefully order to fly with heavy weight which aircraft can not lift up in the air. Cause of heavy weight, aircraft can not turn or maneuver while it is needed. That cause fatal air crash. Irresponsible aircraft maintenance, there are good quality aircraft maintenance crew and both government / business do not care in aircraft maintenance which cause easy aircraft crash in the service time.
