Aircraft bluebookAn aircraft blueboook is a bluebook (value guide) for used aircraft. There are four of these in common use within the aviation industry; Aircraft Bluebook Price Digest, Aircraft Value Reference (VREF), and Airliner Price Guide are paid-subscription publications. International Bluebook is an online free service.
OverviewNone of the aviation industry bluebooks may be expected to give the simple calculation accuracy typical of the US automotive industry books such as Automobile Blue Book, or Kelley Blue Book. A number of issues contribute to the difficulty in presenting a clear figure for a make/model/year, such as lack of central reporting of aircraft sales for either tax or license requirements, the complexity of individual aircraft value calculations, the timing of sales (long timeframes from offer to closing during which time the market can go up or down substantially), multiple synchronous closings for jet aircraft in particular, international currency sales, and non-disclosure-of-price terms included in many transaction documents.
Most banks hire a professional broker/appraiser to allocate a value to an individual aircraft prior to funding. Appraisals usually include an onsite inspection and can be influenced by complex variables such as the year (manufactured year, delivery year, serial number sequence); time on airframe and engines (or until upcoming major inspection and maintenance events); damage (including where/how repaired); logbook and upgrades history; previous owners (number, type usage, and geographic location); maintenance programs (specially approved maintenance schedules and/or power by the hour engine insurance type plans); avionics; options; current mechanical, interior and exterior condition etc.
