 Common Types of Appraisal Reports:

 Letter of Valuation

Consists of a valuation, presented in letter form (2-5 pages) specifically stating the current fair market value or a range of current values for an aircraft. The letter presents the valuation methodology and factors that were considered in the course of reaching the values presented. The letter also discusses the current market for the model of aircraft.

 Desktop Appraisal (Adjusted or Unadjusted Value)

A valuation is rendered based on documentation provided to Jetsworth. The value can be adjusted to reflect the aircraft's current maintenance status, or the value can be presented assuming midlife status on the aircraft and its maintenance functions, such as the engine overhaul and major airframe inspections. The 20+-page report discusses current market conditions and comparable sales.

 Full Inspection and Appraisal

Consists of a hands-on inspection of the aircraft, an audit of the aircrafts' technical records, and an assessment of the value of the aircraft based on the findings of the aircraft inspection and records audit.

A technical aviation representative (inspector) will inspect the aircraft and audit the technical records of the aircraft. The technical aviation representative, who is qualified and licensed as an airframe-and-powerplant mechanic (A&P), will provide a report to Jetsworth that will enable Jetsworth's valuation officer to determine a current fair market and future values for the aircraft. Jetsworth will provide the client with a bound valuation report, including photographs of each section of the aircraft.

 Residual Value or Future Value Projections

Consists of a spreadsheet projecting future values for an aircraft. Can be presented in both inflated and constant dollars. A "must" planning document for leasing firms, banks and lenders.

 Lead Appraiser's Credentials

Jetsworth's lead appraiser, Mary K. (Kathy) Kingston has been appraising general aviation and corporate aircraft since 1990. In January of 2001, Kingston formed Jetsworth, an appraisal firm in the Washington, D.C., area that focuses primarily on the appraisal of turboprop and jet business aircraft.

Since 1997, Kingston has been manager of corporate aircraft appraisals at BACK Aviation Solutions, an aviation consulting firm headquartered in New Haven, Connecticut. She is responsible for determining current and future values of corporate aircraft.

For the seven years prior, Kingston was on staff at the Aircraft Bluebook - Price Digest, a quarterly book that tracks the value of general aviation and business aircraft. She served as editor for the last three years on staff, with responsibility for correctly analyzing the value and market status of more than 3,000 models of aircraft. Also, she was editor of Bluebook's newsletter, Marketline.

Kingston currently holds a private pilot's license, and she formerly owned and operated a piston-powered aircraft.

She is a member of the Aircraft Owners and Pilots Association (AOPA) and the International Aviation Women's Association. She also serves on the business aviation subcommittee of the National Transportation Research Board of Washington, D.C. She is a member of the American Society of Appraisers (ASA), which has certified her as an Accredited Senior Appraiser of machinery and technical specialties / aircraft. Kingston frequently represents Jetsworth at the National Aircraft Finance Association and the National Aircraft Resale Association meetings and activities.

Each year, Kingston generally appraises $1.5 billion worth of fixed-wing aircraft and helicopters.

The U.S. Pilots Association for serving as editor of its quarterly newsletter for six years.
