Adjustable Seat Cylinders
Fabricators sells an "Av-Lok" Seat Actuator which is a PMA replacement
for Piper P/N 587-404 and 89178-010.
They will also overhaul PL Porter Hydrolok seat cylinders more
cheaply than you can replace them. The OEM cylinder is non-repairable.
Air Filters *
(Note that aircraft wiring and circuit breakers/fuses may need to be upgraded
to take advantage of increased alternator output.)
- National AirParts offers FAA-PMA replacements for OEM alternators, with additional current output beyond the
40 or 60 amps produced by the original.
- Plane-Power offers FAA-PMA replacements for OEM alternators, some with additional current output beyond originals.
Auto Fuel STC
Both of these sites contain lots of useful information about using MOGAS
There are two ways to legally add an autopilot to a Cherokee:
Several vendors make STCed autopilots for Cherokees. There is a wide
difference in both price and capability between the different vendors.
- Add an autopilot that Piper supplied as optional equipment for your
airplane. In this case you will be using Piper parts (which are often
identical to another vendor's parts), and Piper documentation for installation
and operation of that equipment. But since this autopilot was certified
by the manufacturer of the aircraft for use with that aircraft, you do not
need a separate STC.
Consult the Piper parts catalog to find out which autopilot parts
are valid for use with your aircraft model and serial number.
- Add an autopilot from a vendor other than Piper that is STCed for
your aircraft. In this case you not only have to buy the autopilot and
pay for its installation, you also have to buy the STC.
- Brittian Industries.
These are less common in Cherokees but the company has been around a
long time and has made autopilots for major aircraft manufacturers.
Their prices appear to be very reasonable.
- Century Flight Systems.
The venerable Century I and Century IIB are STCed for Cherokees.
Both of these were used as original equipment by Piper.
- Chelton Aviation.
Chelton's AP-3C model autopilot provides a wide range of features,
including GPS steering and altitude preselect, in a single low-priced unit.
(note: web site seems to be broken)
These are probably the most popular autopilots for new installations in
Cherokees. They offer several different models with varying capability.
They also offer a GPS steering module and a retro-fit for existing
single-axis autopilots to add altitude hold.
Lots of shops do autopilot repair, but these have been mentioned by
Cherokee Pilots' Association members as servicing autopilots found in
- Autopilots Central Tulsa OK (918) 836-6418
- avionics shop at Lincoln CA (LHM) (916) 645-1441 talk to Dana
- Terry @ Lowe Aviation, Macon GA (478) 788-3491
There are many places that sell and service avionics. These shops
have been recommended by Cherokee Pilots' Association members. If you
recommend a shop that is not listed here, send email.
(see also Autopilot Repair.)
Battery & Starter Cables
Each of the suppliers below sells copper cables to replace the aluminum
originals, along with an STC for installation of those cables on a Cherokee.
Control Cables *
Control Surface Repair
Control Yokes (especially to replace the plastic "bowtie" yokes)
- Avion sells FAA-PMA replacement control
yokes for Piper aircraft.
- Some owners have reported successfully obtaining FAA field approval to use ACS control yokes available from Aircraft Spruce. CherokeePilot.COM has published a 337 from someone who got a field approval to do this.
- There are rumors of people obtaining field approval to use yokes from
Cygnet Aerospace. Cygnet manufactures
new yokes that are PMA for some Beechcraft aircraft. They are said to be
working on obtaining a PMA for Cherokees also.
- Dick Russ has obtained field approval (337) to use Mooney yokes, and
an approved 337 form for one aircraft can be used as basis for approval
of the same modification to another aircraft. For $25.00 he sells a
package that contains a copy of the FAA field approved 337, the letter
of substantiation to FAA engineering, detailed installation instructions,
a list of all the salvage companies (where you might find used Mooney
control wheels) and instructions for refinishing old control wheels.
This is for 3/4 inch shafts only.
For details, send mail to firstname.lastname@example.org
Control Yoke Emblems
- Pride of Ownership Parts
has Piper logo "yoke buttons" to fit both bowtie and ram's horn
yokes which are a close match for the originals.
Control Yoke Universal Joints
- Wag-Aero has PMA'ed cowl latches
for 140s and older 180s with the cowling that opens up on either side.
Part number M-738-000.
Door Handles, Interior
Piper used various auto parts for interior door handles:
FAA-PMA replacements for the older styles of door handles (not the
Volkswagon-style handles) are available from
- The earliest handles were rumored to be from a 56-66 Studebaker.
- A later handle came from a 1967 Ford Falcon (some say Fairlane). For what
it's worth, this site claims to sell Falcon door handles.
- Another kind is recessed into the door and has a small handle that
pulls back. This is a Volkswagon part and these appear to be readily
available, though chrome ones may be harder to find.
- Aircraft Security & Alert has high-security locks that are PMAed.
- CPA members report that suitable locks can be obtained at Lowe's stores for $5 each. First Watch brand, part # 1378.
Door Seals *
Elevator Trim Cranks
On older Cherokees with the overhead elevator trim, the crank
handle is the same as the one used on a 1956 Studebaker. But it's
easier to find a replacement crank at an aircraft salvage place
than to find an old Studebaker. (Though I found a web site for
restoring of Studebakers that mentioned that window cranks
can be obtained from aircraft salvage places.)
FAA-PMA replacements for the overhead trim cranks are available
Other automotive window cranks may fit, but (a) are not approved,
and (b) may block instrument panel illumination from the overhead
lamp (on aircraft where that's the only illumination for the panel).
The easiest way to remove the retainer clip that holds the crank
in (and to replace the clip when you reinstall the crank) is to buy
a tool made for that purpose at an auto parts store.
There are many sources of engines. These sources have been
recommended by Cherokee Pilots' Association members. If you have a
source to recommend that is not listed here, send email.
- Airframes, Inc. sells FAA-PMA
engine baffles for PA-28-140s, and also engine baffles for some other
Piper and Cessna aircraft.
Engine Mounts (repairs and/or rebuilt)
- Arch-Warrior, Inc. offers an STC to covert a Warrior to 180 HP. Walter Sykes, (561) 278-1964.
- AVCON Conversions in Udall KS has an STC to upgrade a Cherokee
with an O-320 to an O-360 180 HP. (620) 782-3317, Robert Williams.
He's very difficult
to contact but one CPA member reports successfully purchasing the STC in
There are rumored to be two versions, one with a fixed-pitch prop and
with a constant-speed prop.
(this is not the same company as Avcon Industries which also makes STCs for various aircraft)
- Art Mattson's R&D (also known as A M R&D) has an STC to upgrade an O-320-E2A to 160 HP.
- Bob Small has a "Bold Warrior" conversion to upgrade a 1976 thru 1983 151/161 Warrior to a 180 HP Lycoming engine.
Email: email@example.com, Phone: (480) 844-2325.
- Lycon has an STC to upgrade an O-320-E2A to 160 HP.
- RAM has an STC to upgrade a Cherokee 140 or 151's O-320-E3D to 160 HP.
(Their web site says "These STCs are not offered to suggest a significant performance increase", which is honest.)
Fuel Selector Valve Rebuilding (esp. PA32)
Fuel Tank Repair and Resealing
- Skycraft Corp. (603) 964-1450 used to do this, but I am told that
they no longer do this.
- Woodstock Aircraft Services, White Lake NY (845) 583-5830
(the web site they advertise in the Piper Owners' Magazine doesn't work)
- Steve's Aircraft. STC - PMA replacement gascolator. Also sold by Aircraft Spruce, and perhaps others.
Each of these makes replacement glare shields for several kinds of aircraft.
Gross Weight Increase
- Air East Airways has an STC to increase the gross weight of a
PA-28-161 that was manufactured prior to July 1, 1982, to 2,440 pounds.
This applies to serial numbers 28-7716001 thru 28-8216300.
Instrument Panel Upgrades
- Associated Aero in Oklahoma City, OK specializes in building new
instrument panels and will build a new flat panel for a Cherokee based
on approved engineering drawings by Dick Russ. Contact Dale Bershea
at (405) 789-5474.
- Avion Research sells updated
instrument panels for Cherokees. These currently require a field approval.
- For those with old-style (pre-1969) panels, the instruments can be
rearranged into something resembling a T configuration by using the existing
holes, replacing the old AN gyros with smaller ones, and using some adapter
plates. This is much cheaper than replacing the entire panel, as the latter
is a structural change. Though the result doesn't look as nice, you can
get close enough to a standard "T" configuration that you probably won't
get confused when switching from one aircraft to another.
Interior Carpeting and Upholstery
- Airtex Products
Replacement PMA'ed upholstery, wall panels, carpet, headliners, for
various aircraft. Also sells yard goods that meet FAA burn rate
requirements for use in aircraft interiors.
- Douglas Interior Products
Carpeting and Upholstery fabric. Much better selection than Airtex,
but these are yard goods, not precut or presewn for your airplane.
They will send you samples if you tell them what you are looking for.
- Hi-Tech Foams
Confor Foam for aircraft seats
- Plane Plastics now offers
pre-cut carpet for Cherokees.
- Skandia Upholstery Supplies
Various kinds of FAA-approved foam, including the Confor Foam that's
good for use in seats.
- TN Wings is said to sell pre-cut
carpet for Cherokees, and is reputed to do a fine job of it, though this does
not seem to be listed on their web site.
- Wicks Aircraft also has Confor Foam.
KX-17x Radio Repair
- Gary Glassmeyer specializes in repairing
King KX-170B or KX-175B series radios and indicators for those radios. (However,
he is NOT an FAA certified repair station.)
- VAL Avionics
VAL Avionics, LTD P.O. Box 13025 Salem, Oregon 97309
Mac 1700 Radio Repair
- Roy Dawson Radio, Orange FL (386) 760-7600
- Bomar Flying Service maintains a web
site which has a large number of manuals, service bulletins, service
letters, TCDSs, and 337s for download.
Piper Manuals on CDROM, updated several times a year via subscription.
Requires Windows 98 or later to use them.
- Essco Inc.
New, used, and reprints of many aircraft operating handbooks, parts manuals,
and service manuals. May be out-of-date.
Mixture and Throttle Controls
- Because of high shipping costs, the best deals on aviation oil are often
to be had from local distributors. Look in your phone book's yellow pages
for Oil, and call distributors in your hometown asking if they sell
aviation oil. I've bought from several local suppliers at much better
than retail prices, quantities as low as one case (12 quarts) at a time,
cash and carry.
- Sky Geek.
- For those who are members, some Sam's Clubs are also reputed to
stock aviation oil.
Panel Lamp Dimmer
- Tanis Aircraft has an STC
for a replacement panel lamp dimmer that should be cheaper than the Piper
part. The web site seems to claim it's valid for at least some Piper aircraft.
Seat Covers *
Seatbelt Buckle Appliques
- From a Piper Flyer Association member: It is common for the front
seat rollers on older cherokees to wear out. Most have a sealed needle
bearing on the rear legs and a common roller on the front. The front
roller is available
from McFarlane Aviation
but the bearings are difficult to find by the Piper part
number. Piper/Aviall lists them at $117 each. I found a cross
reference and tracked them down to the MFG which is RBC bearings. They
have a distributor here in Houston and the bearings price at $57.00
retail. The part number and contact info are as follows:
Piper P/N: 452-386
RBC P/N: 4NCC910P
Motion Industry, 713-688-9100
- Bomar Flying Service maintains a web
site which has a large number of manuals, service bulletins, service
letters, TCDSs, and 337s for download.
- Piper's web
site has some service bulletins available for download. Click on the
URL and next to "Select Aircraft Model", select
your particular aircraft model or "Available Electronic Publications".
Shimmy Dampener STC
Every Piper (except new models) has a shimmy dampener that attaches to
the nose geer steering mechanism and the engine mount. Over time these
shimmy dampeners lose hydraulic fluid, not because of any leak but
because some fluid remains on the actuator shaft after it passes through
the housing. Eventually the shimmy dampeners become ineffective and
this can result in damage to the landing gear and engine mount.
As originally constructed these shimmy dampeners cannot have fluid
added to them to replace that lost over time, and the only solution was
to replace the shimmy dampener at a cost of several hundred dollars.
Aircraft Door Seals
offers an STC that allows the shimmy dampener to be modified to add
a servicing port.
Shoulder Harness Kits
The following vendors offer STCs to add shoulder belts to Cherokees:
Shoulder Harness Repair
(see also Engine Upgrades)
Something to realize about speed mods in an aircraft with a
fixed-pitched prop -
the aircraft isn't going to go any faster unless the prop turns faster
(or unless it's
repitched). You can clean up the airframe or add more power but the
redlines at the same RPM (though perhaps using less fuel and/or
heat while doing so) and that puts an upper limit on your speed at low
So performance mods don't buy you much in terms of actual speed unless
repitch the prop or fly at a sufficiently high altitude that the prop
can turn faster (without redlining) at full throttle. On the other
such mods might give you better handling, better service ceiling, better climb rate,
better ability to handle loads near gross weight, and better looks.
For a fixed-pitch aircraft, the prop pitch and the engine red line dictate the
maximum cruise speed for the aircraft. Multiply prop pitch (typically 58") by
max RPM (2700), and divide the result by 1215 for the max cruise speed in knots.
(divide by 1056 for the max cruise speed in miles per hour). Because the prop
isn't 100% efficient you'll get 90-95% of that at best. Example: a 58"
prop turning at 2700 RPM -> (58 * 2700 * 0.95) / 1215 = 122 knots or 140 miles/hour.
You will not go any faster than that with that prop, no matter how much you clean
up the aircraft.
Before you assume you can repitch your prop, look at your aircraft's type certificate
data sheet (search faa.gov) and/or service manual and see what its pitch limits are.
To repitch your prop to exceed these limits is an (expensive) major alteration that
has to be approved by the FAA and supported by engineering and test data.
Before you "upgrade" your aircraft with speed mods, make sure it is properly rigged.
Proper rigging means first adjusting flaps and ailerons according to the service manuals,
not just lowering a flap until the plane flies level. Proper rigging is the cheapest speed
mod and often as effective as anything you can add. Sometimes people report significant
gains with speed mods but the "improved" speeds they report are close to the "book" speeds
for their aircraft. Yes the speed mod is helping but something else is still wrong, and
if they had fixed that then the speed mod might not have been worth it.
Split Nose Bowl STC
- Aviation Development Corporation
makes an STC to split a PA-28 nose bowl so it can be removed without
removing the prop. Not sure which models this applies to. It's not
listed on their web page, but I've verified by telephone that they sell
it. Price as of this writing (Dec 2006) is $175.
Stall Warning Switch
- McFarlane Aviation makes an FAA-PMA approved replacement which is far cheaper than Piper's. Part # CA450-742N.
Piper service manuals specify MS-122 which is a Teflon-based mold release
agent. Apparently, MS-122 is an obsolete spec and nobody references it anymore.
Here are some alternatives:
- Miller-Stephenson MS-122AD
- Sprayon #500311, Dry Film PTFE (Teflon) mold release agent. Available from
Super Lube Dri-Lube. Supposedly available from Lowe's stores for $5/can.
- Silicone-based dry spray lubricant. Works, but doesn't hold up as well as Teflon.
- Many people lubricate the exposed parts of the struts with MS-5606 hydraulic oil.
This is the same thing the struts are filled with, so it won't hurt them. Problem
with this is that 5606 attracts dirt. If you use 5606, you should wipe them down
quite frequently - say on every preflight.
- Materials that should not be used: automotive hydraulic fluid, gasoline
(mogas or 100LL).
Sun Visors *
Vacuum Pump (& backup) Options
(Note: "Expensive" means around $2K or more.)
Options for primary instrument vacuum (some of which are more reliable than
- Sigma-Tek AEON piston air pump.
PMA replacement for "dry" rotary vacuum pumps. Newly certified.
5 year/2000 hour warranty. Price: around $600.
(Note: several Cherokee Pilots' Association members have reported
early failures with these pumps, so they may not have the bugs worked
out of these yet. For some reason reliable vacuum pump design seems
- Dry rotary vacuum pump - new or rebuilt. Available from most
aviation parts suppliers.
- Wet vacuum pump - new Airwolf
pump with STC. Expensive.
- M-20 is now offering rebuilt
Garwin or Pesco pumps with a lifetime warranty, and is working on getting
certification for new wet pumps. They seem to be less expensive than Airwolf.
- Wet vacuum pump - rebuilt Garwin or Pesco. Available from Aircraft
Spruce and others. However if your aircraft doesn't have the wet pump
documented on its equipment list, you'll need a field approval and a 337
and they're harder to get these days than they used to be.
You'll also need an air-oil separator.
Options for a backup to primary vacuum source or an alternative instrument
- Electrically-powered backup vacuum pump. From
Aero Accessories (pending STC)
and others. Expensive.
- SVS standby vacuum
system. (Formerly available from Precise Flight.) Uses engine vacuum
to keep the gyros spinning. Inexpensive but it requires you to reduce
throttle to produce enough engine vacuum, which could be iffy at high
- Electrically-powered attitude indicator. Available from most sources of
gyro instruments. Use as primary or as a backup. Expensive, though Sporty's
Pilot Shop has a somewhat less expensive model.
- Mid-Continent electrically-powered
attitude indicator with battery backup. Very expensive.
- Solid-state 3-axis inertial sensor driving an attitude indicator-like
display. For instance,
Anywhere Map's Anywhere AI. Not
certified, but maybe useful anyway.
- GPS with a simulated "panel" like a Garmin 196, 296, 396, or 496. A GPS
can serve as a backup for your directional gyro (which might be easier to
read than your magnetic compass), and some GPSes can give you rate-of-turn
information (if it updates the display frequently enough). The "panel"
mode presents this information in a familiar format. A GPS is not a
substitute for gyros, but if your gyros fail the GPS might save your butt.
- Practice partial-panel flying frequently, using magnetic compass,
needle, ball, and airspeed.
- Anywhere Map.
Uses XM satellite broadcasts or Globalstar satellite data service.
Available for PocketPC or Windows XP devices.
- Garmin 396
or Garmin 496.
- NAVAir. Uses XM satellite broadcasts. Displays on PocketPC devices.
Wheel Pants *
(see also Speed/Performance Mods)
- Aero Glass of Griffin GA. (800) 448-9532
- Globe Fiberglass
- Knots 2U
- Laminar Flow Systems
Two kinds of high-performance replacement wheel pants -
Fancy Pants (the earlier design) and SpeedPants (better, more expensive).
Also a nose wheel faring to reduce drag from the nose gear.
Windows and Windshields *
Wing Spar Service Bulletin (SB 1006) Kit
This contains the replacement parts you need to do Piper Mandatory
Service Bulletin 1006, which inspects the wing spar for corrosion,
treats the spar against future corrosion, and replace fuel and
