I was on N600AU the other day. Does anyone know if that is the oldest 757 still flying? I know it was number 3 off the production line, but that is all I can find.

Number 1 757, N757A the prototype is still flying with Boeing as a testbed aircraft. NASA has number 2, the first aircraft for Eastern as N501EA. Regards.

#1 off the production line is with Boeing, used for various things. Its the bird that has/had the F-22 things on its nose.

#2 is with NASA for weather and environmental studies.

So, N600AU would be the oldest 757 flying commercially.

Hmm this is odd...

N600AU
Line No. 3
Del. 9/28/83

N601AU
Line No. 4
Del. 5/25/83

What's the deal with that?

Greg-

N600AU was most likely used during certification and test flight phase and had to be reconfigured for passenger service. This is not uncommon.

I heard MYT's 757, G-PIDS, is the 2nd oldest 757 around, ex Eastern.

G-JALC (MyTravel - ex Eastern - line #5)
G-PIDS (MyTravel - ex Eastern - line #6)
I believe Monarch's G-MONB is the highest time/cycles although it is a relaitively 'new' aircraft being #15 off the line

Although MyTravel and DHL may operate the oldest B757s in the UK in terms of years, if you look at hours flown there are some much younger B757s in the UK that have flown more hours.

Compare these 2 ex-British Airways B757s now with DHL...
G-BIKC (built 1982) had flown 29558 hours in February 2000
G-BIKF (built 1982) had flown 38001 hours in September 2000

...With these younger Air 2000 B757s which have flown with the airline since new
G-OOOB (built 1987) had flown 60194 hours in April 2001
G-OOOC (built 1988) had flown 61980 hours in April 2002

I think these figures demonstrate how much harder charter airlines work their aircraft than their scheduled counterprarts - the Air 2000 aircraft have flown roughly double the number of hours as their British Airways counterparts even though they are 5-6 years younger. The flip side of the coin is that the scheduled aircraft will have a high number of cycles (around 1 cycle per flight hour) while the charter aircraft operate longer stage lengths (around 0.3 cycles per flight hour) due to their average stage lenth being slightly over 3 hours.

Air 2000s oldest B757 G-OOOM (built 1986) had only flown 34237 hours in December 2002, betraying the fact that it spent it's early career with Eastern Airlines in the US before joining Air 2000 in 1990.

Monarch's oldest B757s also have a high number of hours, but don't appear to have been worked as hard as their Air 2000 counterparts...
G-MONB (built 1983) had flown 59805 hours in February 2000
G-MONC (built 1983) had flown 63137 hours in April 2002

If the figures are extrapilated it would support Steady Eddie's assertion that G-MONB is the highest time/cycles B757 in service. With G-OOOB and G-OOOC about to be retired (G-OOOA has already gone) they probably won't catch up...

While MyTravel do have some very early B757s, they again flew with Eastern Airlines, and then spent several years in storage before joining Airtours in 1995 so these aircraft aren't actually that old in terms of airframe hours...
G-MCEA (built 1983) had 48092 hours in March 2001
G-PIDS (built 1982) had 48882 hours in February 2001
G-RJER (built 1982) had 49351 hours in February 2001

All the figures are available on the CAA G-INFO website:

Hope I didn't bore you with numbers too much! Just wanted to show how that how an aircraft is used is far more important to its "age" than how long it has been in service  Smile

Crosswind,

didnt bore me one bit, actually was very interesting to read, makes me look at the age of aircraft in a different way. So taking this into account would the more flight hours a 757 fly reduce its lifespan dramatically? For example will the BA and DHL 757's fly longer with their current amount of cycles that that of a charter aircraft which is younger in terms of production years buy flys more cycles?

How are Low Cost airlines using their aircraft, working them harder and longer than Charter airlines? And if so in the long run would this affect the airlines profitability when it comes to early fleet renewal or very high maintinance costs?

Yours Sincerely,
Jason Nicholls

Glad I didn't bore you!

Put simply, the more flight hours/cycles a plane has, the shorter it's useful life. That's largely irrespective of it's age in years, however it's age in years will also be a factor because over time newer more advanced aircarft are introduced wich tend to make an aircraft obsolete. Hoewever ex-charter aircraft should still have very long lives ahead of them....

The B757 has a fatigue tested airframe life of 100,000 hours (as far as I know, this may have been subsequently extended)

The charter B757s (mentioned above being retired) are around 15 years old and have around 60,000 hours:
- If they went to another charter operator who flew them in a similar manner that would give another 10 years service - taking the aircraft up to 25 years old
- If they went to a scheduled operator with a similar utilisation to BA then they will have around 25 years service remaining before they reach 100,000 hours - taking the aircraft up to 40 years old
- If they were converted to cargo aircraft, they would have very long useful lives due to the fact that freighters generally have low utilisation.

In the long term, aircraft lives can be extended with further fatigue testing and it is rarely airframe hours that make an aircraft obsolete. More often it is fuel efficiency, maintenance costs/reliability, performance and modernity of flightdeck systems when compared to younger aircraft which mean it is no longer financially viable to continue operating an older aircraft.

Low cost airlines aircraft have a high number of daily cycles but not as many hours than charter aircraft. This is for 2 reasons, they generally don't fly at night and their average stage length is much shorter than that of a charter airline. In the long run working your aircraft hard makes the most economic sense, even with the higher maintenance costs that brings. Having very expesive assets sitting idle will always cost you money!

Very interesting Crosswind, many thanks for the insight, and what a co-incidence, on my visit to DUB yesterday G-MONA was parked up all alone.

Yours Sincerely,
