The first jet I flew was a Lear 28. As my first F.O. job, it was quite a rare plane to get to fly. It climbed like crazy, but was fuel critical.

The wing is a single piece. A demate inspection lifts the fuselage off to check for corrosion.

I am curious if the lj23 wing was one single unit or two cant wings. The LJ23-25 training manual is confusing. Many pilots do not know for sure.

thanks

True the basic 25 cruises at .78M the Raisback conversion I flew could cruise at .80M. I knew a guy who was somewhat famous for flying around the World in a balloon who insisted he exceeded M1.0, but I seriously doubt it. Aerodynamically it could probably go to .90 or above, but the tip tanks and wing would keep it from getting much faster, at least in controlled flight.

Proof reading error!

Although the 104 and F5 could easily "cruise" around .9 and higher -If I remember correctly the Lear 25 was just in the .8 Mach range. The rest is valid -but we don't want to "gild the lily".
The Lear 25 is a good enough plane -particularly considering its birthdate -that it doesn't need to claim to do better than it does. mea Culpa!

I was a mechanic for a Lear 25G, s/n 372. It was modified with Dee Howard extras such as saddle fuel tanks at the wing root, convergent/divergent exhaust nozzles, and some large strakes on the tip tanks and engine pylons. A real rocket and great aircraft.

I was an electrical/avionics engineer on the 25 and worked on the 28 program in Wichita back in the early 70's. I believe 28-003 was in our service department recently down here at Bombardier in Tucson. 28-003 may have held a time to climb record. We built very few 28's, and even fewer 29's.

jock williams yogi 13 was mistaken or real lucky, flying at .90 in a .82 airplane with a shaker and puller

In 1980 we chartered Lear 28 #3 for a NY to Naples, Fl. trip. It was the plane's first revenue trip. We climbed out of Westhampton, NY right on up to 51,000', and believe me, we were over grossed with people and baggage. It was an amazing trip in an amazing aircraft. I will never forget it. For my father's nurse, it was her first airplane trip of any kind - and at 51,000', no less. She never realized the event was as "record breaking" (altitude wise) as it was. I do remember alarms kept going off (chimes) up front (I was in the jump seat behind co-pilot) and as an amateur pilot, I was a little apprehensive. I would NOT do this today, being older and wiser, but I'm glad we did it then.

I flew the Lear 25 for about 15 months -although sadly only 400 or so hours -but I loved every second!

It was a little rocket -cruised handily around .9 Mach but approached at no more than 120 kts. It felt like a TBird (T33).Tiptanks looked the same also -but in truth held WAY more fuel!

The only problem was that it burned fuel at low level like it was going out of style. The burn rate taxiing for takeoff was about 700 pph -the same as in cruise at 40,000 feet.
The boss always wanted us to fly at FL450 -but I kept telling him that the emergency O2 masks were inadequate should there be a depressurization.
Fortunately there never was!
I would love to have done an aerobatic airshow in this little beauty -but rules are rules...!
