Average Life Expectancy Of A Boeing 747

Fri Dec 07, 2001 1:36 am

Hi!

On December 2nd, I took a short trip on a 29 year old Boeing 747-200 (which is btw. in a perfect condition). Are there many 747 that stay in service for such a long time? Anyone know what the average service age is? How long can they be expected to fly (that is, each aircraft, not the whole 747 fleet)

What's the oldest 747 that you have travelled on (which is still in full service)?

Well it probably would depend on how the aircraft was used . Like what kind of routes it was running , maybe if it was running long distance routes with little turbulance , or hard landings. I think a B747-200 could last around 35-40 years , if the plane was maintained properly.

An aircraft's "age" is measured in cycles (takeoffs and landings) and flight hours.

I'm sure others can give a more accurate count, but typically I would guess a 747 is good for around 100,000 hours and 30-40,000 cycles. The 747SR, the short-range version built for the Japanese domestic market, has a beefed-up structure and landing gear in order to take even more cycles, as they make a lot of cycles every day, instead of 2 or so per day for usual 747 users.

The oldest 747 that I had the pleasure to fly in and is still in service would be El Al's 4X-AXQ (747-238, ex-Qantas) he was "born" in 1974 and he still flies....

Apart from some 747s that went through the hands of many owners and leasing companies or beside the few short-range versions from Japan the average 747 reaches an age of 25-30 years in service. By far the most 747s retired by now were more than 25 years in service.
The SPs experience a shorter service life because of its economical disadvantages. Many just reached 20 years of age before retirement.

On the other hand: Northwest and SAA still have some 747-200s that are 30 years old now and still fly regularly!

So I guess that the 747 is the aircraft type with the longest average service life so far.

Which, we hope, turns out to be an even number  Smokin cool

Last year I flew SFO-HNL on United Airlines 747-200.
It was one of the best flights I've ever had. It was an ex-Quantas 747 too.
I don't know what year it was build though.

I've probably flown on quite a few older 747 classics, although at the time that I did I wasn't too aware of the fact. The oldest one that I can clearly remember would have to be one of BA's 747-100s, a couple years ago, just before they completely retired them. Does anyone know when those were built? I didn't take down the reg. # unfortunately.

Regards.

This particular aircraft I was talking about in my original post is TF-ABQ, a 747-246B which has been in service with Air Atlanta Icelandic since February 1999. The Aircraft entered service with JAL in 1972 as JA8113 and stayed with them until Air Atlanta Icelandic got it. For more information check this record in the Icelandic Aircraft database.

The flight I mentioned was a special Christmas celebration flight organized by the "First Flight Society" (in Iceland) in cooperation with Air Atlanta Icelandic. Arngrimur Johannsson, the founder of Air Atlanta Icelandic and his daughter Ragnhildur Arngrimsdottir flew the aircraft and took us in a 100 minute trip around Iceland as well as up over the north polar circle. Santa Clauses were onboard, singing and playing the accordion. During the flight, the 300 passengers could have as many soft drinks, sweets and cookies as they wanted. Most of the trip the aircraft flew very low so the view was quite spectacular.

After this flight, TF-ABQ went to Manston where it will undergo an overhaul before the Haji flights start in early 2002.

In the hands of CI, KE, SQ and a few others it could only be 10 years at the MAX !!!!
