CESSNA 152 OWNERS AND OPERATORS
Did you know?
You can bypass McCauley S/B 219 and AD 95-21-02
forever by installing a Sensench propeller and spinner? Increase your engines
rated horsepower to 115 @ 2700 RPM by only doing this prop change on Air Mods
N.W.'s STC SA1OO8NW?
Did you know?
You can also make your existing 0-235-L2C
engine deliver 125 HP by only changing to high compression pistons, changing
timing, and modifying engine baffles, in addition to changing props?
Did you know?
More than 500 152s and A-152s have been
converted to this configuration, since the STC certification in 1980.
Well now you know!...
And it is called the SPARROW HAWK
conversion!
If we now have your attention, here are some details.
Unbelievable Performance Increase...
Cruise speeds of 135+ MPH at 75% power! Service Ceiling of over 16,000 ft.
35% shorter take off roll and 50% less distance to clear 50 ft. obstacle!
Greatly improved density altitude performance and high altitude climb
rate!
OVER ALL REDUCTION IN FUEL CONSUMPTION
Higher compression burns fuel more efficiently and develops more power. G.P.H.
is equal to, or less than, the stock engine and speed is increased. Time to
climb is less so the overall fuel mileage is much better!
DRASTIC REDUCTION IN LEAD FOULING
Combustion chamber deposits are greatly reduced virtually eliminating
frequent and costly plug cleaning and aborted flights.
CLEANER OPERATING ENGINE
Lead sludge deposits in the sump, oil passages, pistons and rings is reduced
to almost nil. This common problem in the stock engine has caused major
component damage and has even resulted in engine failure.
OFFERS THE MOST PERFORMANCE FOR YOUR MONEY
The full Sparrow Hawk conversion compares closely with the performance of 150
mods and is much less costly. There is no weight and balance change and no
effect on operating limits (even to the Aerobat) and range is increased, not
reduced.
CONVENIENCE OF TWO STAGE INSTALLATION POTENTIAL
The full Sparrow Hawk mod consists of 3 individual STCs. One converts the
engine, another applies the modified engine to the airframe and includes the
baffle change, and the 3rd is for the Sensenich propeller and spinner. The
engine and airframe STCs may be installed and the stock propeller retained
(limiting RPM to 2550 max.) or the propeller and spinner may be installed,
with the stock engine and baffles. At any time the remaining part may be
added to complete your full Sparrow Hawk modification.
VALUE IS INCREASED
Many articles have appeared in major aviation publications heralding the
benefits of the SPARROW HAWK. Resale value of these converted airplanes is
considerably higher than stock 152s and they are in constant demand. Some
FBOs operate fleets of them. Once they have used one, the stock 152 is no
longer acceptable!
