flying the Piper Pa38 Tomahawk
By Julie K.Boatman
A lot of pilots met their first Tomahawk during
primary training. But it looks more like a time
machine than a run-of-the-mill trainer, with its
double doors and bubble view. And this is one
time machine that almost anyone can afford - for
less than the price of a convertible, a pilot
can expand precious weekends by spending more
time at a destination and less time getting
there.
When the original Piper Aircraft Corporation
first conceived a new trainer in the mid-1970s,
the company polled CFIs to determine what traits
this airplane should have. The Tomahawk delivers
what these special customers ordered: an
airplane that provides honest response to pilot
inputs, a comfortable cabin with great
visibility, and big-airplane-style handling.
Cockpit layout is geared for safety, with the
fuel selector front and centre on the console.
Flight instructors we spoke to feel strongly
that the Tomahawk does what Piper intended.
"It's the best primary trainer ever built" says
Jim Tafta of Richmond Flight Centre in West
Kingston, Rhode Island. "The student is well
trained, and they can't get away with some of
the things they can in other trainers." The
feedback is overwhelmingly positive, with one
caveat: This airplane, though a trainer, still
demands proper training of its pilots from a
qualified instructor. Those with the training
have flown the Tomahawk for thousands of hours
without incident.
Flight characteristics
Pilots need special training because of the way
the airplane was designed to stall and spin.
The wing design, the same basic section as on
the Beech Skipper, was a cutting-edge airfoil -
the NASA-generated GA (W)-1 - in the late 1970s.
On the Tomahawk airframe, the wing produces
aggressive stall characteristics suitable for
teaching primary students about stall
recognition and recovery. However, that design
led to a higher incidence of stall/spin
accidents, perhaps because the airplane cannot
simply fly itself out of a spin like other
trainers - it wasn't meant to, so that students
would learn proper control inputs. This is one
airplane where it pays to know the territory.
The Tomahawk controls have a
heavier feel, as they were designed to mimic
those of a much larger airplane. In addition,
the T-tail delivers reduced elevator control
response at low airspeeds - and this is actually
reflected in the accident reports to a larger
degree than stall/spin issues. During the
takeoff roll, the elevator becomes effective at
around 35 KIAS. If the pilot has been impatient
and is holding greater back-pressure in an
attempt to raise the nose before this point, the
airplane will over-rotate. The same effect
reverses on landing, "especially when a headwind
shears off"; according to Adam Harris, director
of maintenance at East Coast Aero Club at
Hanscom Field in Bedford, Mass., who has owned
four Tomahawks over the years. These are simply
attributes of an airplane that doesn't fit the
standard mould, Harris points out. "We rent them
to people with 10 hours and they always come
back."
In fact, if you're looking for an airplane to
provide a steppingstone to a larger aircraft,
the Tomahawk makes a sound choice. You face an
easier transition in the long run because of
these big-airplane characteristics.
Cross-country flier
The Tomahawk is roomier than you might think,
and taller pilots feel more comfortable in this
airplane than in a Cessna 152. Ventilation is
also better than average, with automobile-style
vents blowing cool air at altitude on summer
days. The cabin is wider by several inches than
other two-seat airplanes, so you needn't be
intimate with your passengers.
The airplane's greatest
utility is as a day-tripper. Paul Diette of
Mansfield, Mass. bought his 1982 Tomahawk II for
trips around New England with his wife - trips
that take less than three hours and only require
light bags. The airplane has proven perfect for
the mission: Places like Martha's Vineyard and
Bar Harbour, Maine, are reachable in half the
driving time.
Usable fuel is 30 gallons,
and during cruise Diette figures he bums between
six and seven gallons per hour. He typically
flight plans a true airspeed of 105 knots.
Endurance is about 3.5 hours with an hour
reserve - with full fuel you can carry roughly
325 additional pounds of pilot, passenger, and
baggage, based on the empty weight of a
reasonably equipped Tomahawk (around 1165
pounds). It goes over gross quickly (it is a
two-seat aircraft, after all), but because of
the size of the cargo area, light-but-bulky
items, such as an Adirondack chair that Diette
flew home after a successful shopping trip, can
be handled.
Model history
Just fewer than 2500
Tomahawks were produced in model years 1978 to
1980, with the most units produced from 1978 to
1979. Aftermarket kits for the rear wing spar,
vertical fin attach plate, and rudder hinge were
developed to address several AD's (airworthiness
directives) that were issued soon after these
models hit the ramp. In 1981 and 1982, the
Tomahawk and Tomahawk II were made with many of
the ADs taken care of at the factory.
These later models are
preferable, as the installation of AD kits in
the field was accomplished with varying degrees
of accuracy. Aircraft with these field ADs may
exhibit divergent flight characteristics from
the standard Tomahawk because of what are
considered vague installation instructions from
Piper, according to several A&Ps we spoke to. Of
course, as the gods of economics would deviously
demand, fewer of the later models were produced
as steeply rising interest rates and a soft
economy helped send new aircraft sales to the
basement in the early 1980s. Annual production
runs during 1980 to 1982 were less than 200
aircraft a year - not even one-quarter the
yearly production of Tomahawks in 1978/79. It's
no surprise that prices steadily increase with
model year, from $16,000 for a 1978 model to
$18,500 for a 1982.
Original Tomahawks rolled off the line with
basic VFR instrumentation. The so-called
"Special Training Package No. 1" gave the
airplane gyros, external and internal lighting,
dual brakes, one (then) King nav/com and
transponder, an ELT, and a heated pitot tube -
for a total price of $19,730. Strangely enough,
the same airplane (with a radio upgrade or two
along the course of 20 years in service) costs
about the same, not adjusting for inflation, as
it did in 1979.
That wing
One thing for prospective buyers to keep in
mind: The Tomahawk wing has a lifetime fatigue
limit of 11000 hours. Some long-in-the-tooth
airframes have nearly that many hours after
years on school flight lines. Currently, a set
of used wings from an otherwise toasted Tomahawk
is the one recourse. There is talk of pursuing a
life extension of the wing.
