Fixed Gear PA-28 Cherokee Technical Data:

STC SA1228CE approves the installation of aluminum wing extensions, new-style wingtips, stabilator extensions and dorsal fin on the following Piper airplanes (Arrow and Lance models are listed lower on this page):

PA-28-140, -150, -160 (all serial numbers)

PA-28-180 (serial numbers 28-1 through 28-7205318)

The modification extends the Piper Cherokee wing span from 30' to 32' 2.5", installs a new Hoerner style wingtip, extends the stabilator span (OPTIONAL) from 10' to 12' 10.5" and installs the new style dorsal fin fairing to replace the old "Nixon nose" fairing.  Minimumcomponents must be on the airplane (wing extensions and dorsal fin) to meet the FAA approval requirements for this STC.  Stabilator extensions are optional.

The wing modification consists of removing the old round style wingtips and installing either of these two options:

  • Riveting on the Piper metal wing extensions, extending the navigation light wires and screwing on the new style wingtips, or,
  • Install the new wingtips with Whelen Recognition lights, extend the navigation light wires and run a new wire for the recognition lights.  This is generally the best option as parts are readily available and the addition of the lights in each wingtip improve taxi and landing lighting significantly over the single nose cap light.

If desired, the stabilator modification includes adding Piper Cherokee skins, ribs and spars. The stabilator parts must be purchased from your Piper Dealer, Distributor or other Piper parts source.  The stabilator tip is reinstalled after the aluminum structure is riveted in place. A new stabilator balance tube may be required to properly balance the stabilator after the modification.

The dorsal fin fairing is the same two-piece fairing assembly approved by our other Piper STC's.

The labor time to install this modification is approximately sixteen hours. This time does not include paint.

This modification adds beauty and makes the airplane appear much newer, more expensive and handle with improved flight characteristics.

Performance:

Before this modification the "fat wing" or "Hershey Bar" wing Cherokee has a tremendous sink rate in a reduced power situation. This installation results in a gentle sink rate by adding wing area, thereby reducing wing loading. The modification improves the climb rate and cruise speed. Stall speed is reduced. Another improvement results by reducing wingtip vortices, which cause disturbance of airflow over the aileron during slow speed flight. The result is an improved aileron response with improved "roll control power" making cross wind landings much easier.

Many pilots complain of "wing heaviness" on the short wing Cherokee when fuel is burned from one tank for more than 45 minutes. With the extended wingspan fuel can be used from one tank for an hour and fifteen minutes without any noticeable wing heaviness.

The long stabilator requires very little effort to flare on landing. The additional length makes it easy to hold the nose off the ground during a full stall landing, eliminating the problem of porpoising. The added stabilator area requires less trim during cruise, which results in less drag.

The added lift of the wing, new design wingtips, reduced drag of the stabilator and the vertical fin fairing all combine to give a faster cruise speed, increased control power, better rate-of-climb, extremely docile stall characteristics, greatly reduced sink rate and the appearance of a brand new airplane.

Piper Cherokee Arrow Technical Data:

STC SA2490SW approves the installation of aluminum wing extensions or new-style wingtips and the dorsal fin on the following Piper airplanes:

PA-28R-180 (all serial numbers)

PA-28R-200 (serial numbers 28R-35001 through 28R-7135329)

The wingtip modification uses the same parts as the fixed gear models above and extends the wing span from 30' to 32' 2.5", by installing new Hoerner style wingtips and the new style dorsal fin fairing to replace the old "Nixon nose" fairing. All components must be on the airplane (wing extensions and dorsal fin) to meet the FAA approval requirements for this STC.

The wing modification consists of removing the old round style wingtips, riveting on the Piper metal wing extensions and the new style wingtips or by installing the fiberglass wingtips with Whelen Recognition lights.

No stabilator modification is available for the Arrow since it comes from the Piper factory with a longer stabilator than fixed gear models.

The dorsal fin fairing is the same two-piece fairing assembly approved by our other Piper STC's.

The labor time to install this modification is approximately ten hours. This time does not include paint.

This modification adds beauty and makes the airplane appear much newer, more expensive and handle with improved flight characteristics.

PIPER LANCE (not available for aircraft with fuel tanks in the wingtips)

PA-32R-300 S/N 7680001 and on;

PA-32300 S/N 32-7940001 and on;

PA-32RT-300 S/N 32R-7885001 and on;

PA-32RT-300T S/N 32R-7787001 and on.

The wingtip modification uses the same wingtips and reco lights as the fixed gear models above.  This approval installs new Hoerner style wingtips and the new style dorsal fin fairing to replace the old "Nixon nose" fairing. All components must be on the airplane (wing extensions and newer style dorsal fin) to meet the FAA approval requirements for this STC.  If you need replacement wingtips on your Lance this will be far less expensive than purchasing new Piper wingtips.  Performance improvement to cruise speed and climb are positive but very slight on the Lance models.

The wing modification consists of removing the old round style wingtips and installing the new style wingtips with Whelen Recognition lights. 

No stabilator modification is accomplished on the Lance since it comes from the Piper factory with a longer stabilator than other models.

The dorsal fin fairing is the same two-piece fairing assembly approved by our other Piper STC's to replace the "Nixon Nose" fairing.  The dorsal fin is not approved as a separate STC for the Lance and can only be installed when the new wingtips are installed.

The labor time to install this modification is approximately ten hours. This time does not include paint.

This modification adds beauty and makes the airplane appear much newer, more expensive and handle with improved flight characteristics. Additionally you will find these wingtips much less expensive than replacement Piper wingtips.
