Although based on the Convair 240, the 340 was largely a new aircraft with greater wing span (32.11m) and area; a longer fuselage for 44 passengers; R-2800-CB16 or CB17 engines; greater all-up weight of 21,318kg; and many interior design improvements. The first aircraft flew on 5 October 1951 and the first delivery to an airline (United Air Lines) was made on 28 March 1952. A total of 209 had been built by January 1955, when the last two production aircraft were delivered to REAL (Brazil). The USAF also operated 340 as C-131 or VC-131 transports, flying and ECM trainers and for other duties; while the US Navy/Marine Corps received 37 transports as R4Y.
Convair 440 Metropolitan
The 440 was a development of the 340 with modifications to increase speed by about 8km/h and to reduce the noise level in the cabin. Special kits were also made available to convert 340 to 440 standard. Accommodation was provided for between 44 and 52 passengers. The prototype first flew on 6 October 1955 and 162 were built before production was phased out in the spring of 1958. A few were also operated by the USAF and US Navy.

PBA ... Providence Town Boston Airlines/Naples Airlines, had a couple of the 440's that serviced the northern states in the summer, then were ferried to Naples, Fl for the winter season. I was a passenger on a flight from Naples to Marathon in the Fla. Keys one beautiful night and remember the harmonic and resonant sounds of those P/W's. Nice airplane.

I was chief of stan/eval for our C-131 in the MA ANG. We named it "DUMBO". I checked out quite a few jet fighter pilots who had never flown a recip. I flew it to the bone yard at DM but, as it turned out, this was not it's last flight. It was sold and restored and is flying with the CAF at Camarillo, CA.

Dear members and ex Convair Crew
Sorry to insist on the subject but I did send already 2 request on the subject.
It is about a wreck I saw in Chile back in 1974 but up to now I was no able to fin informations on this Convair 240 or 600. I also like to know what became of Convair 240 N17417 as it had the same colors as the one I saw in the south of Chile.
If any person could help me it would be just great.

About 20 years ago I taught welding at George T. Baker Aviation in Miami, Fl. At that time they had onof these aircraft, it was owned by The Doobie Bros. It was a runout and was donated to the school. Don't know if they still have it.

The R-2800 engines in the Convairs had the nicest sounds. We called it, "the pratt & whitney lullaby".

Dear members and ex Convair Crew, back in March this yera, I did send a mail related to a Convair 240 or his turbo prop version that I possibly saw in the south of Chile back in 1974. My memory may have made a joke so I'm willing to accept any other possibility and also I can send the picture to any person interested in this aircraft.
|Dane Hays, 15.03.2012|
Does anyone remember the 340 that Howard Hughes kept as a flying office in the early 1950s? I have a photo if anyone is interested.
|Michel Anciaux, 04.03.2012|

Flew as a crew member (in the back) on an USAF C131B (tail no. 37815)from late 50's to early 60's. We did the early flight testing of the Atlas guidance system out of the GE Flight Test Opertion in Schenectady, NY. Loved it.

The man who gave me the flight training and type rating ride
in the convair 440, was, Bill Conrad. The airplane hadn't flown in a year. The first landing, we touched down a little fast, he called for reverse thrust. being it was the first time in this plane, I pushed the throttles too quickly, the no. 2 engine quit and caught fire. no. 1 went into max power reverse. He told me to set the throttles at idle. Then he cooly restarted the no. 2 engine, the fire blew out and we taxied in.

I flew the Convair 340 and 440, in the late 70s. We flew the Wall Street Journal newspapers between IAD - GSO and CLT. Had over 2000 hrs. in them. It was a rock stable airplane. Rode smoothly in even the most turbulent air. Had to shut down engines a few times, usually, due to cylinder failures. It flew great on one engine. Loved flying them.
|Jim Stalker, 06.02.2011|
I flew both the 340/440 for B&H Freight owned by Corp Air out of BDL for a little over a year in the early 90's and logged about 1000 hrs of pure fun. We flew contract for Flying Tigers to BOS, ORD, Montreal. During that time we lost 2 clyinders ( one I have at home to do a lamp maybe ) and 1 engine shutdown over McGuire AFB with a landing into PHL. Great airplane and experience . Any B&H pilots out there give me an email
Do you have any comments about this aircraft ?
