BRUSSELS, March 17 (Reuters) - French engine and

aircraft equipment maker Safran has offered remedies in

an attempt to secure EU antitrust approval for its $1.8 billion

bid for Collins Aerospace's flight controls business, an update

on the European Commission website showed on Monday.

The EU competition enforcer, which did not provide details

in line with its policy, extended its decision deadline on

Safran's bid for the U.S. company to April 4 from March 21.

It is now expected to seek feedback from rivals and

customers before deciding whether to accept the concession,

demand more or open a four-month long investigation.

Safran in December announced the sale of its

electromechanical actuation business in North America, which

includes its intellectual property, operations assets, staff,

and customer agreements for HSTA systems, to U.S. aircraft parts

maker Woodward.

It said the deal was related to the Collins acquisition.

The EU antitrust watchdog had in February asked rivals and

customers whether the deal would give Safran more market power,

a person familiar with the familiar told Reuters.
