1 [AIRCLAIMS LOGO] Exhibit 99.7 Our Ref: 97377/BV/EP/kw Morgan Stanley Aircraft Finance (MSAF) 30th November, 1997 c/o Wilmington Trust One Rodney Square P O Box 551 Wilmington Delaware 19899 USA Attention: Mr Kieran O'Keefe Dear Sirs, BASE VALUATION OF 33 AIRCRAFT PLUS ONE ENGINE AS AT 30TH SEPTEMBER, 1997 Further to the instructions of Mr Kieran O'Keefe, Morgan Stanley & Co., we are pleased to be able to provide our opinion of the adjusted "Base Value" of each aircraft in the enclosed portfolio of aircraft managed by ILFC as indicated in the attached table, reference 97377-3009/EP/ADJBV. Our valuation is based on the portfolio details as provided by Morgan Stanley in the course of the assignment. The point of valuation is 30th September, 1997. Airclaims' valuation of the portfolio takes into account data supplied by Morgan Stanley, including updated information made available in November 1997, regarding the specification of the subject aircraft, including their type and variants, years of build, engine types and variants, accumulated airframe and engine hours and cycles, and serial/line number (where relevant). Information has also been provided in many cases concerning the airframe and engine maintenance status, and, where possible or necessary this has been interpreted or extrapolated and our value opinion adjusted accordingly. We have additionally referred to the data held in the Airclaims CASE Aviation Database to supplement and complete the data required for the valuation, including cumulative airframe hours and cycles and have assumed that, unless otherwise advised, each aircraft is a typical example of its type, model and age, and is generally in good condition, with all airworthiness directives and significant service bulletins complied with. Airclaims Limited Cardinal Point, Newall Road, Heathrow Airport, London TW6 2AS Telephone (44) 181 897 1066 Facsimile (44) 181 897 0300 [LOGO] Telex 934679 http://www.airclaims.co.uk Registered Head Office as above. Registered in England No. 710284. VAT Reg. No. 224 196 87 2 [AIRCLAIMS LOGO] As requested by MSAF, we have provided our value opinion under BASE VALUE scenario. Airclaims believes it to be very important that value definitions are understood by all parties and that such values are always considered in conjunction with their definitions. BASE VALUE (TO ISTAT DEFINITION) The Base Values presented in the attached table are based on the definitions as outlined by the International Society of Transport Aircraft Trading (ISTAT). ISTAT's definition of Base Value equates in principle to the previously used appraisal term, Fair Market Value. The ISTAT definition is as follows: A Base Value is the Appraiser's opinion of the underlying economic value of an aircraft in an open, unrestricted, stable market environment with a reasonable balance of supply and demand, and assumes full consideration of its "highest and best use". An aircraft's Base Value is founded in the historical trend of values and in the projection of value trends and presumes an arm's length, cash transaction between willing, able and knowledgeable parties, acting prudently, with an absence of duress and with a reasonable period of time available for marketing. In most cases, the BASE VALUE of an aircraft assumes its physical condition is average for an aircraft of its type and age, and its maintenance time status is at mid-life, mid-time (or benefiting from an above average maintenance status if it is new or nearly new, as the case may be). In this instance, because of the relative youth of the portfolio, all the Base Values pertaining to the fleet have been adjusted for maintenance status where available and appropriate. No physical inspection of the subject aircraft has been undertaken by Airclaims in conjunction with this assignment, and no attempt made to verify the information available to us, which therefore assumed to be correct as given. Abbreviations used on the tabulated valuation pages include: Type Aircraft type, model and variant Eng. Engine Type and Variant MSN Manufacturers Serial Number REGN Registration MTOW Maximum Take-Off Weight ADJ BV Adjusted Base Value H-L BV Half Life Base Value Morgan Stanley Aircraft Finance (MSAF) Page 2 3 [AIRCLAIMS LOGO] Whilst the tabulated values are given as single figures, it must be borne in mind that the determination of such values involves a multiplicity of variables, and that some variation in perceived values must be expected, due to for example, any potential inaccuracies in the data provided, and also because the aircraft have been valued "sight unseen". In this case we consider that a tolerance of +/- 4% may reasonably apply to the aforementioned calculated values. Please note that valuations given by Airclaims are valid only as at the date of issue. Subsequent to that date there may be alterations in the world aviation market, or in the status and physical condition of the subject aircraft or other general factors that may affect Airclaims' valuation opinion. I trust the foregoing is satisfactory and to your requirements. Yours faithfully, /s/ Edward Pieniazek Edward Pieniazek Director, Consultancy & Information Services Encl.
