| The Swiss FFA P-16 jet fighter, cancelled by the federal government in the late 1950s, caught the attention of Bill Lear Snr, who saw in it the basis for a twin-jet executive aircraft. He initiated preliminary design work at St Gallen, Switzerland, in November 1959 and sold his electronics company to the Siegler Corporation. Lear then formed the Swiss American Aviation Corporation to develop the aircraft, known originally as the SAAC Lear Jet 23. An important objective was to keep the aircraft's gross weight below 5670kg so that it would qualify for single-pilot operation under FAA CAR.3 regulations and for air taxi operations without requiring CAB approval.
In August 1962, after the design had been finalised and tooling was in progress, Lear transferred the project to Wichita, Kansas, and renamed the organisation the Lear Jet Corporation.
In every way a stylish aircraft reflecting its fighter origins, the Learjet 23 marked a new era in 'bizjet' design, offering very high performance - if not much headroom.
The prototype made its first flight on 7 October 1963, the second and third aircraft being flown on 5 March and 15 May 1964 respectively. Following the receipt of certification on 31 July the first production Lear Jet 23 was delivered on 13 October 1964 to the Chemical and Industrial Corporation of Cincinnati, Ohio. Despite the fact that the Lear Jet was considerably smaller than the piston-engined aircraft that it was designed to replace, it more than made up for this in performance, and though intended for single-pilot operation the basic layout was for a crew of two and for five to seven passengers. The first 30 production aircraft to be completed were powered by 1293kg thrust General Electric CJ610-1 turbojets, but
the remainder of the production run of a little over 100 Lear Jet 23s had CJ610-4s of similar thrust.

| scottb60, e-mail, 08.06.2012 21:05 Most 23's have been brought up to 24 standards, jet pumps and such and quite a few have the Dee Howard wing and reverses.
With prices below $100,000 pretty common the fuel consumption might be acceptable. Watch the inspection compliance a 12 year check is pretty expensive.
With lighter weight Williams engines they could be viable for many many years. reply | | david, e-mail, 08.06.2012 03:57 i've wanted a 23 or 24 all my life, now i'm seriously thinking of buying one. anyone have ideas on which is better value for money and anyone know of a good bird for sale? best wishes, dr.p reply | | Naga, 01.06.2012 06:29 How many 23s were built? reply | | Fred Shrum, e-mail, 17.07.2011 09:09 Looks like Joe Moore above flew a /c with N numbers a lot like we had at JetAmerica., DCA, i. e.

| | Scott Boyd, e-mail, 31.05.2011 07:34 You can probably find the episode on You Tube or Hulu.
The 23 and 24 were quite a bit different especially in systems. Electric fuel pumps replaced by Lear invented jetpumps, a refined airfoil and other changes that made the 24 a distinctly different aircraft. Subsequent Lear's 25, and 35-36 were basically the same aircraft because it worked so good.
One thing I have always remembered was the CJ-610, with King Airs, Jetstreams, Turbo Commanders, etc., an engine start meant watching for any hint of a problem, with the Lear you hit the Starter-Generator switch START Thrust Lever idle at 10% rpm. Then do whatever needs to be done and move the switch to off, with ground power or generator
without. reply | | Ben Gay III, e-mail, 31.05.2011 03:35 Jerry Dunn-
Help! How do I find the Batman and Robin episode with N461F in the background?

bfg3@directcon.net reply | | Jerry Dunn, e-mail, 17.05.2011 05:43 I just got through watching a 1966 episode of Batman and Robin. They had a fist fight in a hangar with Lear 23, N461F as the center piece of the fight scene with Riddler and his gang.
I'm type rated in LR-JETs with 5,300 plus hours in the 23 and 24 from 1972 to 1988. I don't think I ever flew this particular Learjet though, N461F. reply | | John Hess, e-mail, 22.12.2010 21:24 Hi Ben,
I think I read a post from Art's daughter, Karen, that he and her mom had passed. I believe that 61F was scraped after suffering major damage on landing. Good to hear from you, Ben. reply | | Ben Gay III, e-mail, 08.12.2010 04:30 John Hess -
Hello, old friend!
Just curious: Is N461F still out there somewhere? Is Art Stagg still among us?
All the best!

We made a month-long trip "around the world" during my tenure. Under HM's ownership it was based first at Oakland (OAK) and then, after the runway was lengthened, we moved it to Gnoss Field (DVO formerly 056). HM operated a Cessna Flight Center at Gnoss. reply |

Roger, I'm still around. Started flying Lears in 1969. 24-164.
I met you at FLt Safety in the 70’s under John Holms reign. Syl Strood, Chuck Cox, Ken Elley, and many more. I knew them all. I did my initial at LGA then they moved to ICT early 70’s. Swede was the manager then.
I went on to fly various aircraft over my 51 years in aviation. I retired in 2019 @ 75 years old and living in ICT. Just turned 79 in May.
Sure miss the old gang.
Hope you are doing well. Regards, Lou
