747SP Has A Short Fuselage - What About 747SR?

Sat Jan 26, 2002 10:08 pm

When I compare a picture of the 747SR to a picture illustrating the 742, I really can´t see any differences...

Sure I´m a novice, but please help me with this one guys!  Smile

The difference 747-200/747SR is like 747-400/747-400D, i.e. the 747SR is a special domestic 747-200 with the same fuselage.

There are two main differences between the B742 to the B742SR and between the B744 to the B744D.

Since the 'SR' and the 'D' are for a very short flights, many lavatories and galleys had been removed so the companies (JAL and ANA) could put some more seats inside (and I guess that the clearance between the seats are small).
The B744D can take up to 600 passengers.

Because of the short flights they do many more takeoff and landing than the 'normal' planes so the two planes fuselage were strengthening, especially the landing gear.

By the way, the B744D looks like the B743 or the B742SUD from the outside.

Long live the B747

Thanks Avi!

Do you know where I can find info about SR´s payload, reach etc?

A few years ago, I had the unfortunate
chance of flying on a Japan 747SR.
It was the most umcomfortable flight
I've been on.

The seats were extremely cramped,
in order to fit 500+ passengers. If
anyone makes me fly on the 747SR
again, I'll pack a parachute and jump out.
(if they manage to drag me onboard in
the first place)

It sort of does, but keep in mind that the 747-400D has the improved wing>fuselage fairing.

To confuse things further, some late-production 747-300 also have the modified wing-fuselage fairing.

Anyway, the only users of the 747-400D is JAL and All Nippon. So, if you see what looks like a 747-300 of either carrier with late model GE engines, it's a "D".

The differences between the 747-200 and 747SR are under the skin.
Basically a stronger 747-100, the SR has stronger fin attachments, crown splices over the centre body, undercarriage support, stabiliser root, fin root, wing lower surface, wing/body splice, in-spar ribs, spoilers, ailerons and trailing edge supports. Improvements were also made to the middle and rear spars and the leading edge and nacelle support structures.
The first SRs had JT9D-7 engines giving 43,500lbs of thrust each.
JAL took 7, the first one flew in late august 1973.
In 1978 All Nippon received the first of 17 aircraft, but powered by CF6-45A engines, (46,500lbs each). These aircraft were based on the higher-gross weight -100B 747. JAL took 3 similar aircraft, but with the JT9D engine.
In 1986, JAL took 2 odd -300 based SR versions. Odd because they were called -100B(SR/SUD), denoting that they were actually based on the SR version of the -100B, but with the -300's extended upper deck.
JAL then ordered 4 -300SR versions, delivery began in 1987, these has 54,000lb thrust JT9D-7R4G2 engines.
One of the orginal SRs crashed in 1985, when the rear pressure bulkhead failed. This had not been repaired properly after a hard landing in 1978.
The first SR was brought back by Boeing, until being sold to NASA in 1988 for conversion into a Space Shuttle carrier.
The second SR also went back to Boeing, in 1988 it began structural testing at Everett to evaluate the long-term fatique properties of the 747.
The 747-400D also had reinforcement to cope with high-cycle operations, JAL and ANA had 20 in service by 1997, the first being delivered in 1991.
Incidentally, Boeing originally called the 747SR the 'Super Airbus', they even painted the 747 demonstrator aircraft with that title in late 1972!

And just to confuse matters even more, JAL had two 741s converted with a stretched upper deck and were structurally reinforced for the additional cycles, creating what became known as a 747-146SR-SUD. Only two of these rare aircraft exist.

Here is one more thing that is worth to add to GDB historic cover.
On August 12th 1985 a JAL B747SR crashed into Mt. Osutaka in Japan.
520 passengers and crews out of 524 were killed in the second ever worse air accident and the ever worse for a single aircraft.

The accident happened because of a faulty repair of the rear bulkhead.
Long live the B747

actually, I believe "SR" signifies "Structurally reinforced" although many texts have described the abbreviation mission-wise as "short-range."

I believe I recall all JL and NH 744D are in the following configuration: main deck 545 Y, upper deck 24 C. Someone with superior knowledge please correct/confirm.

The 743D has in theory a capacity of 624 pax in an all economy layout. I don´t know if this configuration was ever actually applied. And if the 743 can hold 624, the 744 should too.
