On 2 March 1952 Piper flew the prototype of a new twin-engine aircraft which it then identified as the Piper PA-23 Twin-Stinson. A cantilever low-wing monoplane of all-metal construction, it had a tailplane set high on the fuselage and mounting endplate fins and rudders, retractable tricycle landing gear and an enclosed cabin seating four in two pairs, and was powered by two 112kW Avco Lycoming O-320 flat-four engines in wing-mounted nacelles. The tail unit was very soon replaced by a conventional tailplane with centrally mounted single fin and rudder, and it was in this form that it entered production in early 1954 as the PA-23 Apache, later designated PA-23 Apache 150. The type continued in production as the Apache until 1965, by which time 2,166 had been built, including 1,231 examples of the first production version. The original model was followed in 1958 by the PA-23 Apache 160 with 119kW O-320-B engines, and with some interior revisions so that it was classed as a four/ five-seat aircraft (816 built), and in 1962 by the similar PA-23 Apache 235,
which introduced swept tail surfaces and 175kW Avco Lycoming O-540-B1A5 flat-six engines (119 built).
With sales of the Apache 235 declining, Piper developed an improved version of this aircraft which introduced a 186kW O-540 engine and provided six-seat capacity. This entered production under the designation PA-23-250 Aztec in 1959-60, the US Navy acquiring 20 of these aircraft for use in a utility role, designating them UO-1, changed to U-11A in 1962. The Aztec was built until early 1982 when production was suspended. In finaj production form the type had the designation PA-23-250 Aztec F, and was available also as the generally similar PA-23T-250 Turbo Aztec F which differed by having Avco Lycoming TIO-540 engines with a Garrett turbo-charging system.

I have owned and flown 2 F models throughout the Bahamas and Fl. Great airplanes. Put the second in the water after a trip to Haiti following the earthquake. Panel fire (radar, I think)forced me down. Plane sand in under 2 minutes. Still the easiest, best overall airplanes I have owned.

In reply to Don B -- flaps - on take off ??? Stall warning ?? I've owned an Apache for 39 years, and to my knowledge no such things. -- PJY

Flew Aztec 'D' modals in Florida/Bahamas and Africa. I agree with the other comments...its a great load carrier and has a good X-country speed. A good honest roomy twin.

Been flying Aztecs since 1969 and there is no better utiltarian 6 seat twin out there. I have flown n240jb(turbo) since '79 and been up to 23,000' but usually in the low teens and get good speed and great load carrying capability combined with all kind of room inside. Lost an engine once at 15,000' and made a gentile landing 30 miles away. Been to Alaska twice in it and almost everywhere else. Great aircraft.

I used to haul passengers and freight from Florida throughout the Bahamas in an E-model "Az-Truck." Probably the most fun flying I ever had. As a freight hauler, we always said, "if you can get the door closed, it'll fly." Only had two incidents in the airplane - had a jug lift off the block on first flight after a 100 hour inspection and made an easy single engine landing - the second incident, I was on short final over the fence and went to full flaps when the aircraft rolled to the right uncommanded... I had full aileron and rudder inputs to the left and just before I went to power for go around, I looked out the left wing and saw my flap down then looked to the right and noticed the right flap retracted...got my hand off the throttles, retracted the "flap" and then eased in power to regain centerline and mushed her onto the runway. The tower called down to me and remarked that "it must have been a heck of a crosswind"... "yeah, right," I told him as I taxied off the active. That was one day I could have wound up a ball of tin foil, for sure.

We have a highly-modified 1957 Apache; it certainly is NOT UGLY; it is FAST and can carry a bundle!

I used to own and operate a red and white Apache 160. Great bird!! I converted it to the proper T instrument configuration and sold it to the FAA.

I trained all three of my kids in our 1669 Aztec. It is an excellent platform for instrument flying and is great for multi trng. Two of the three went on to be major airling pilots. I used it alot for Angel Flights--it had the room and weight carrying capacity for almost anything.

A friend and I owned 1004P back in the late 60's. I believe it was suppose to be the second production unit produced. 1 and 2 were production prototypes and 1003P was the first. What a great airplane even with the small engines and such good memories. Thanks for the Museum.

This was my pop's third and final plane. I liked the Bonanza 35 the best. The Apache could carry a load, but it was ugly. We took off from a field in Virginia with 5 sob's on a very short private runway. At the end was a two story wharehouse. With flaps and engines at full throttle we cleared the roof by raising the gear the moment we felt lift. A dangerous trick that worked thankfully. Even at that we got the stall warning and had to level off and fly over several more buildings to build air speed. I almost wet my pants. Later I'll tell you about the time I did.
Do you have any comments about this aircraft ?
