LONDON (Reuters) - Activist hedge fund TCI Fund Management on Monday called on Safran SAF.PA to set up an ad-hoc independent directors' committee to review the company's valuation of Zodiac Aerospace ZODC.PA, according to a letter seen by Reuters.

London-based TCI said in its letter to the board of Safran, which is planning a $9 billion takeover of Zodiac, that such a committee was required by French law and under the recommendations of the local regulator.

The hedge fund firm said this committee should appoint a major international financial institution to perform an independent fairness opinion on Zodiac shares.
