The FAA directive was immediately adhered to by aviation regulator of countries whose airlines have so far bought these latest aircraft.

Yesterday, Japan had grounded 24 Dreamliner owned by two of its airlines-- ANA (All Nippon Airways) and Japan Airlines.

Air India officials said they have grounded all the six planes in its fleet with immediate effect following the FAA directive and the DGCA advisory.

They said that FAA has directed the grounding of the entire Dreamliner fleet till such time as the aircraft manufacturer Boeing "demonstrate compliance" of various

measures the American regulator has asked it to carry out.

However, the officials maintained that its services will not be affected in any major way as flights to Paris and Frankurt operated by the Dreamliner will now be serviced by Boeing 777.

While one of the six planes is always on a standby, three are used on the domestic sector and two on international including Paris and Frankfurt, they said, adding that domestic services would be absorbed by the existing fleet of aircraft.

The American aircraft maker had last Friday jointly announced investigations with FAA after three of these aircraft owned by the Japanese carriers suffered glitches this month -- an electrical fire, fuel leakage and a broken cockpit window.

In September last, Air India had also experienced a glitch in its Dreamliner's liquid cooling system and electrical power system, which had led to the grounding of all three of these planes at that time.

After the faults were rectified, these aircraft have been flying regularly on select domestic and international routes.

Regarding the problem of fuel leaks, the Air India officials had said this was not something "unusual as it occurs in all aircraft types. Such problems have to be rectified immediately but these are not anything new or different."

Boeing had designated a team in Delhi for any trouble- shooting for Dreamliners.
