Fitch Affirms Willis Engine Securitization Trust (WEST)

NEW YORK--(Business Wire)--
Fitch Ratings has affirmed Willis Engine Securitization Trust
(WEST) as follows:

--Class 2005-A1 notes at 'A';

--Class 2008-A1 notes at 'A';

--Class 2008-B1 notes at 'BBB'.

Fitch's analysis incorporated expected cash flow to be available
to the trust over the remaining life of the transaction. This
expectation is based on several factors including supported aircraft
type, current portfolio value, potential lease rates, and perceived
liquidity of the portfolio. Lease rate and portfolio value
expectations have been updated to reflect Fitch's views on certain
supported aircraft given the aviation market volatility and
significantly elevated fuel prices.

WEST was affirmed as it was found to have credit support
consistent with its current ratings.

Fitch will continue to monitor this transaction and update ratings
as warranted.

Fitch's rating definitions and the terms of use of such ratings
are available on the agency's public site, www.fitchratings.com.
