180 HP LYCOMING ENGINE & PROP CONVERSION: Speed increase of approximately 25 miles per hour. Higher twin and single engine ceiling, shorter take-off and increased useful load. Lighter weight props with dynafocal engine mounts reduces noise and vibration which results in lower operating costs, more comfort and increased performance. Optional Q-Tip Props reduce sound levels by five DB and slightly increase climb speed. The down time is about one month.

EXTENDED NOSE with FULL NOSE WHEEL WELL DOORS

The nose is 31 inches longer than standard with a baggage compartment. Nose wheel well doors fully enclose wheel in streamlined aerodynamic bubble. This modification does more for performance and aesthetics than any other mod except the 180 HP engine conversion. Airspeed is increased by ten to twelve mph. Rate of climb, single engine performance, CG stability and cabin ventilation are substantially increased. Modifications are made of impact resistant fiberglass. This combination of modifications goes far towards making the Apache perform and look like a modern day light twin. Relocation of antennas are extra. Down time three weeks.

DORSAL FIN

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. Reduces single engine control speed and yaw tendency in turbulence.

Greatly improves single engine performance

****Now Available!****

Rams-horn style control yokes

We currently have this STC but our supply is 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.

NOTE:

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