NEW DELHI, July 14 (Reuters) -

The probe into last month's crash of an Air India plane in

Ahmedabad is far from over and it is unwise to jump to any

premature conclusions, airline CEO Campbell Wilson said in an

internal memo on Monday after the release of a preliminary

report by investigators.

The memo, reviewed by Reuters, comes after the report

depicted confusion in the cockpit shortly before the crash of

the Boeing Dreamliner that killed 260 people. It said the

plane's engine fuel cutoff switches flipped almost

simultaneously and starved the engines of fuel.

"The release of the preliminary report marked the point at

which we, along with the world, began receiving additional

details about what took place. Unsurprisingly, it provided both

greater clarity and opened additional questions." the memo said.

Wilson added: "The preliminary report identified no cause

nor made any recommendations, so I urge everyone to avoid

drawing premature conclusions as the investigation is far from

over."

The Boeing 787 Dreamliner bound for London from the Indian

city of Ahmedabad began to lose thrust and sink shortly after

takeoff, according to the report released by India's Aircraft

Accident Investigation Bureau (AAIB).

The memo said the preliminary report found no mechanical or

maintenance faults and that all required maintenance had been

carried out.

The preliminary report, released on Saturday, suggested no

immediate action for Boeing ( BA ) or GE, whose engines were

fitted on to the aircraft.

The AAIB, an office under India's civil aviation ministry,

is leading the probe into the crash, which killed all but one of

the 242 people on board and 19 others on the ground.

Air India has come under heightened scrutiny on multiple

fronts following the crash.

On July 4, the European Union Aviation Safety Agency

said

it would investigate budget unit Air India Express, after a

Reuters report revealed the airline failed to promptly replace

engine parts on an Airbus A320 as mandated, and falsified

records to indicate compliance.

ALPA India, which represents Indian pilots at the

Montreal-based International Federation of Air Line Pilots'

Associations, rejected the presumption of pilot error in the

Ahmedabad crash and called for a "fair, fact-based inquiry."

"The pilots body must now be made part of the probe, at

least as observers," ALPA India President Sam Thomas told

Reuters on Sunday.
