ITEM 1.         SECURITY AND ISSUER

      Pursuant to Rule 13D-2 promulgated under the Act, this Schedule 13D/A
("Amendment No. 4") amends the Schedule 13D filed on April 27, 2007 (the
"Original 13D"), as amended by Amendment No. 1 dated July 25, 2007, Amendment
No. 2 dated October 22, 2007 and Amendment No. 3 dated November 26, 2007.

     This Amendment No. 4 is being filed by O.S.S. Capital Management LP
("Investment Manager"), Oscar S. Schafer & Partners I LP, Oscar S. Schafer &
Partners II LP, O.S.S. Overseas Fund Ltd., O.S.S. Advisors LLC, Schafer Brothers
LLC, Oscar S. Schafer and Peter J. Grondin. Amendment No. 4 relates to the
ordinary shares ("Shares") of Hexcel Corporation, a Delaware corporation (the
"Company").

ITEM 4.         PURPOSE OF TRANSACTION.

Item 4 of the Original 13D, as heretofore amended, is being amended to include
the following:

     On February 19, 2008, after considering the issue for more than two months,
the Company informed the Investment Manager that it would be willing to nominate
only one of the Investment Manager's three nominees to the board of directors of
the Company (the "Board"). The Investment Manager immediately advised the
Company's Board representative that this would not provide sufficient change in
the composition of the Board and, on February 25, 2008, sent a letter to the
Company advising that the Investment Manager had no alternative but to take its
nominees directly to the Company's shareholders and to proceed with a proxy
contest to elect all three of its nominees to the Board. A copy of the letter is
attached hereto as Exhibit A and is incorporated by reference.

ITEM 7.         MATERIAL TO BE FILED AS EXHIBITS

Exhibit A.  Letter dated February 25, 2008

of the undersigned certifies that the information set forth in this statement is
