Aircraft Digest
(Blue Book)

What you need
to know
Have you ever
wondered about the market value of your aircraft – or one you are considering
purchasing?
Years ago, as
an aircraft sales manager my copy of the “blue book” was my most important sales
guide as we took a diverse collection of aircraft as trade-ins on factory new
machines. Back then, the guide could only be purchased by bona fide aircraft
dealers and some government officials. Things have changed as the general public
can now acquire copies.
Although there
were some differences in market pricing between Canada and the USA with varying
exchange rates and tax considerations, the price ratios were all relatively
accurate and the guide was invaluable in establishing market and wholesale
values.
But the guide
provides much more. This “blue book” is chock-a-block full of equipment data
that advises prospective purchasers of typical avionics, factory options, serial
numbers for applicable production years, engine specifications and thereby
allows readers to determine the true value of a specific aircraft offering.
Incidentally,
this guide also includes the most popular models of helicopters!
Although the
blue book doesn’t show data on my Diamond Xtreme motorglider, this is likely due
to the fact they are scarce in North America, it does include most types
including rarities such as the: Melex M18 Dromader, Zlins, Varga Katchina’s,
Tiger Aircraft and Ayers Thrush.
Interestingly,
there is a value trend for some aircraft that tells readers whether values are
changing rapidly on various aircraft types. This can lead to increased profit or
decreased losses to prudent readers.
OTHER USEFUL
DATA
Appendices
provide extremely useful information that can protect blue book owners from
making expensive mistakes. For instance the “Technical Information” appendix
lists: Airworthiness Directives, Engine Prices and Aircraft Specifications and
Performance Figures (including helicopters).
Another
appendix comprising 112 pages details supplemental pricing information that
includes: airframe time, avionics pricing with respect to depreciation,
conversions and modifications, deicing equipment, engine maintenance programs,
floats, paint and interior pricing and calculations to consider aircraft in
prime condition or those with damage history.
The directories
and glossaries section shows contact information for manufacturers of: aircraft,
engines, avionics, propellers and service providers. Additionally a glossary of
aviation terms maximizes utilization of the guide and interest rate charts allow
purchasers to assess the true cost of financed purchases.
There’s much
more, but, suffice to say, the blue book is essentially a one-stop shopping
guide into the world of aviation. As our dollar stretches towards par value,
(with continuing fluctuations), knowing aircraft values in American dollars is
especially useful now because we can find relative bargains south of the border
with our growing Canuck buck.
Why you
can’t live without the guide
We’ve all seen
folks pay far too much for a high time aircraft and still others “give away”
pristine planes because they didn’t know current market values. There is no
better tool to take to a bargaining session than a blue book (cash works well
too)!
Sellers often
“overprice” their planes and it doesn’t hurt to educate them to realistic market
prices because the guide considers every variation likely to be encountered in a
sale. Similarly, purchasers often try to scoop an aircraft and might need a wake
up call from a guide-equipped seller in order to fetch a fair price.
The blue book
brings truth to the table and is completely non-biased when it comes to closing
sales between opinionated parties. If you don’t have a blue book you may be
weaponless during pricing battles. The price? The $319.95 U.S. rate includes
four quarterly issues per year (You could always share an annual subscription
with others.). The cost may seem high for some readers; however, one must
consider the massive amount of research and tabulation the company performs to
ensure accuracy.

Plane Information
- |
1980 Piper Warrior II, 9225 TT, 240 SMOH, dual KX-170B, IIIB a/p, strobes,
super nice paint, recent interior
|
|
1. Calculate the value of engine time.
Determine from glancing at Base Average that midtime is
1000 hours. Since this Warrior’s engine time is well below midtime, we
know to add value for this feature.
1000
(SMOH) – 240 (Warrior’s engine hours) = 610
(hours below midtime) x $6.50 (value of each hour, shown
in this model’s Add for line) = $4,940
(amount to be added to the value of this warrior for low engine time).
|
2. Calculate the
value of airframe time.
- Determine the number of hours this Warrior has flown per year:
9225 hrs
(AFTT) / 25 (age of this Warrior) = 369
(hours flown per year by this Warrior).
- Now determine
the fleet average for this model by glancing at the “Average Hrs Per Year”
chart in Appendix A. This figure will be compared with this Warrior’s
total time to determine how much the Warrior’s airframe/total time
deviates from the fleet average. Remember, airframe time is allowed to
vary from the average by 10% (higher or lower), so no calculation is
required for variances ranging from 1% to 10%. 369 (number of hours this
Warrior has flown per year) – 272 (number of hours flown each year by
typical Warrior, as shown in “Average Hrs Per Year” chart in Appendix A) =
97 (number of excessive hours logged per year by this Warrior when
compared with the typical Warrior).
- Calculate
what percentage this excess represents:
97 hrs / 272 hrs =
35.6%
- Therefore,
this Warrior has flown an average of 36% more than the typical Warrior
built between 1977 and 1994.
- Determine whether this Warrior is considered an early or late model.
Examine the year spread in the “Average Hrs Per Year” chart. In this case,
the chart includes Warriors manufactured between 1977 and 1994, so this
1980 model would be considered “early” because it falls closer to the
older models (1977-1983) than the newer Warriors (1985-1994) include in
this “average hours” study. We know now we will use the shaded area within
the “Deduct for high time” arc on the Airframe Chart in Appendix A.
- Determine the percentage you will deduct from the value of the aircraft
because this Warrior exceeds the fleet average by 36%. Locate 36% on the
bottom (X-axis) of the Airframe Chart and make an imaginary line up to the
shaded area of the “deduct” arc. Trace that line over to the left side
(Y-axis) of the chart to learn the percentage you will deduct from the
Bluebook’s price: in this case, 7%. If you were figuring an appraisal on
the retail level, you would multiply the Bluebook’s retail price by .07 to
determine the dollar amount of the deduction. If your appraisal uses one
of the Bluebook’s wholesale prices, multiply that wholesale value by .07
to learn your deduction. (See Step #5 below.)

3. Determine the value of this Warrior’s avionics and equipment.
Compare the Base Average listing of equipment and
avionics with this Warrior’s equipment and avionics. Prices in the
Bluebook already include the value of equipment listed in Base
Average so you need to account only for equipment that is on this
Warrior but not listed in the Base Avg.
No value is
added for the dual KX170B (nav com) or strobes since this equipment
already has been factored into the values shown in the Bluebook. The
(Century) III B a/p (2-axis autopilot) is considered a supplemental piece
of avionics, and its value, both retail and wholesale, is found on this
model’s Add for line.

4. Account for other factors that may affect the value of this
aircraft.
This airplane has “super nice” paint and “recent” interior. The Bluebook
allows you to add half the cost of paint and/or interior if the work was
done within the preceding 12 months, so be prepared to add value for these
features.
Also, we do not
know whether this plane has been damaged in its 25 years of flying. Some
dealers say that no mention of damage history (DH) is nearly a sure bet
that the plane has been damaged; otherwise, they say, the ad proudly would
declare that the plane never has been damaged (NDH). The buyer definitely
should raise the question of damage before agreeing to purchase an
aircraft.
