Price List

Many of the following kits have previously been offered for the Apache model aircraft. All of the following are now fully STC'd for installation on the PA23-250 series aircraft as well. Prices do not include installation or freight charges.


SPEED-SLOPE WINDSHIELD

$1,495
Installation of this windshield results in lower cabin noise levels, dramatically enhanced appearance and improved visibility. Cruise speed is increased by 3-5 miles per hour. This windshield mounts approximately eight inches farther out on the nose than the original, and you will need to obtain a 1 foot by approximately 7 foot piece of glareshield cloth to install in front of and partially under your existing glareshield. We recommend a vertical card compass and the electronic OAT instrument of your choice be installed at the same time. Call with questions, or if your aircraft has a hot-plate installed. Windshields available in gray tint, green tint or clear. speed-slope windshield image 1 speed-slope windshield image 2 speed-slope windshield image 3 speed-slope windshield image 4

 New! Modern Throttle Quadrant Control Lever Kit

 
 

 New! Vortex Generators

 
* Lower Lift Off Speed (Includes Horizontal Stabilizer Fairings)
* Lower Stall Speeds
* Improved Controllability
* Improved Characteristics
* Improved Safety
* S.T.O.L. Benefits
* Improved Aileron & Rudder Effectiveness
* Smooth Ride In Turbulence
* More Stable Instrument Platform

 DORSAL FIN

$ 1,395
Adds stability and about 2-3 MPH to cruise. Enhances appearance and reduces VMC by approximately seven MPH. You will notice that after initial rudder trim is set, it will require almost no re-adjustment as fuel burns and weight shifts during flight. The fin is fiberglass, and is about three times the size of OEM. The fin is large enough to consider the option of installing hidden antennas and/or remounting an existing antenna inside. dorsal fin image 1 dorsal fin image 2

 WING TIPS

$ 2,195
Adds lateral stability at low speeds and improves aileron control. Cruise speed increased by about 3-5 MPH. Enhances appearance and includes recessed navigation light mounts with streamlined lenses. Reduces wingspan by about 32 inches over stock tips. wing tips image

 FLAP GAP SEALS

$ 895
Increases climb performance & decreases stalling speed. Also shortens take-off roll and improves overall handling characteristics. Cruise speed increased by 3-4 MPH. flap gas seals image

 'E' MODEL NOSE KIT

$ 5,195
Another great enhancement to overall appearance, this modification adds about 14 inches to length compared to stock nose. Reduces noise levels and extends baggage compartment space. Looks identical to Aztec E & F nose. Includes streamlined landing-light lens and improved ventilation intake. This mod is highly recommended when using any nose-mounted slaved compass and is a must for any radar installation. We have noticed that slaved compass "swing" caused by electro-magnetic interference (landing light turned on) is minimized after nose installation. e model nose kit image 1 e model nose kit image 2 e model nose kit image 3

 VORTEX GENERATOR KIT

 $ 1,995
Reduces stall and VMC speeds increasing short-field capability. (Approximately $750 replacement cost if aircraft must have generators replaced due to repaint, hail damage, etc.)

 INSTRUMENT PANEL STC KIT

$1,195
Approved for Aztec, Apache & Geronimo aircraft, this one-piece design eliminates cockpit display clutter and is shock-mounted to isolate full panel. Several panel styles include back-lighting or post-lighting, engine instrumentation and radio configuration options. Dual centerstack design with option for copilot instruments. Price includes STC paperwork, eight Lord mounts and complete installation plans. STC affords the owner/installer great latitude in customizing panel to fit individual avionics & instrumentation needs without the need for a field approval. Installation available, call for details. We also offer a new fiberglass glareshield in two styles for $389. Note: PMA approved, 2-1/4 inch round, dual backlit engine instrumentation/fuel gauges available soon! instrument panel stc kit image

 GLARESHIELD

$ 389
One piece fiberglass glareshield in two styles made to fit panels listed above. Enhanced appearance, visibility and practicality. Must be covered or padded with approved materials of owner's choice (not included.) Call for details.

 INFLATABLE DOOR SEAL

$ 449/895
Models available with automatic (electric) or hand pump. Very noticeable difference in noise levels with this unit installed. Call for current price & availability.

 QUARTER-INCH SIDE WINDOW KIT

$ 995-1,149
1/4" side windows replace OEM double-paned 1/8" windows. Popular kit includes frameless vent pilot window, non-vented co-pilot window, both rear & right center windows and 3/16" (.187) emergency exit window. Kit price is $995 for clear and $1,149 for tinted; MSLP. Add $125 and $150 respectively for quarter inch-beveled emergency exit window. (This one is difficult to install and requires extreme care & patience.)

 HIGH DENSITY SOUNDPROOFING KIT

 $ 1,295
Reduces noise level to a point of normal conversation. Improves passenger comfort and is an effective barrier against heat transfer. Can be installed with or without the purchase of a new interior.

 MAJOR AIRFRAME INSPECTION and OVERHAUL

 
This inspection far surpasses a 1000 hour inspection and brings the airframe back to factory new tolerances. Price will vary greatly with condition of airframe. Call for details.

Purchasing a combination of the above modifications will qualify you for a discount. Discounts also available for AOPA members and FBO’s.

****Coming Soon!****


Rams-horn style control yokes. We currently have this STC but our supply has back-ordered. A new manufacturer is in the process of designing an updated style yoke similar to the Aztec F yoke. It will include push-to-talk switches on both yokes, provisions for autopilot cut-off switches on both yokes, and electric trim switch-mounting provision on pilot yoke. Price will be about $1,295 per pair.

Rochester engine instrumentation.We are currently working with Rochester Gauges of Texas to introduce new 2-1/4" dual-needle STC'd backlit gauges. All gauges will be electronic with analog movements. They will include: Fuel quantity with new sending units, oil temp, oil pressure, fuel pressure, CHT & EGT. These gauges will eliminate the inaccuracy and availability problems associated with the old AC and Stewart Warner obsolete OEM units installed at the factory. These will be available for injected, carburated and turbo-charged models. A 3-1/8" dual electric STC'd tachometer will also be available. This unit will pick-up signals from the magnetos, thus eliminating the need for noisy, heavy tach cables or expensive tach generators. Other advantages of these new gauges includes reduced weight, modern appearance and no oil or fuel lines running into the cabin. All gauges will be switchable for 14v or 28v operation.

Co-pilot brakes.We have been working with a firm in Wisconsin to add co-pilot brake pedals and hydraulics similar to the OEM design found on some E and most F model Aztecs. These will become available for all Aztec and Apache/Geronimo models in the near future.

Engine nacelles. We are in the process of designing an adaptation of our Geronimo engine nacelles to fit the Aztec models. They will have the same 2-piece design as the Geronimo. These nacelles incorporate a camlock system which allows a four minute removal and re-installation time. The nacelles will include a re-designed induction air intake system and will improve cooling, reduce shock-cooling and decrease drag. This improvement will also increase combustion air inlet airflow.

NOTES:

  1. All prices subject to change without notice.
  2. The state of Montana has no sales tax.
  3. Kit prices do not include crating or shipping charges.
  4. All modifications include PMA-approved parts.
  5. Speed figures established by exhaustive testing, and are relative to particular airframes and other installed modifications. They are accurate to within 2%.
