The Civil Aviation Authority of Nepal (CAAN) has issued new regulations that prohibit "non-essential" helicopter flights, including those for sightseeing, till September.
It has also restricted external load operations or sling flights, as well as the practice of showering flowers from helicopters.
The decision came two days after the tragic chopper crash incident that took the lives of six people who were on board the Manang Aircraft.
The CAAN has also formed a team for daily control and supervision of helicopters and STOL (Short Take Off and Landing) operations.
Although some experts attribute the crash to unfavorable weather conditions, an investigation committee is currently examining the incident to uncover the actual cause of Tuesday's crash.
This is not the first incident of aircraft crashing in Nepal.
In the past three decades, at least 17 fatal plane crashes have taken place in the country, according to the Aviation Safety database.
