Quoting AMFAproud (Thread starter): NWA is parking A320s that have only 25000 cycles because of this AD 98-22-05 |
Quoting AMFAproud (Thread starter): I guess they just don't have the talent to fix them anymore. This is the website: |
Quoting Nitrohelper (Reply 2): a 15 year old 737, or DC-9 -50 ? |
Quoting Jetjack74 (Reply 4): 25,000 cycles is kind of alot for a narrowbody is kind of alot don't you think? |
Quoting Jetjack74 (Reply 4): Anyhow, aren't the major structural repairs farmed out 3rd party contractors? |
Quoting Jetjack74 (Reply 4): Quoting AMFAproud (Thread starter): NWA is parking A320s that have only 25000 cycles because of this AD 98-22-05 25,000 cycles is kind of alot for a narrowbody is kind of alot don't you think? What was the total time on the airframe? |
Quoting Jetjack74 (Reply 4): Quoting AMFAproud (Thread starter): I guess they just don't have the talent to fix them anymore. This is the website: Either that, or the cost of fixing them isn't worth when the mainline capacity is drawn down. NWA isn't the only carrier retiring 1st generation A320's, Cypress Airways retired some of theirs. Anyhow, aren't the major structural repairs farmed out 3rd party contractors? |
Quoting Norcal773 (Reply 10): Another excuse to keep the DC9's flying even longer. |
Quoting Apodino (Reply 9): I would take this with a grain of salt. |
Quoting DfwRevolution (Reply 7): The 737 service-life is 75,000 cycles, which can be extended with intensive maintenance checks and overhauls. |
Quoting Apodino (Reply 9): Sounds like a bitter AMFA mechanic trying to stir the pot against NW to me. But I could be wrong. |
Quoting Jetjack74 (Reply 13): I've observed that most aircraft we operate, begin and end their lives here |
Quoting Isitsafenow (Reply 6): Thats a young model 50. Try 1970's vintage for the 50's. |
Quoting AA737-823 (Reply 17): Yet I believe NONE of your "world's largest DC-9 fleet" were purchased by NWA ever. The DC-10s were all second-hand, except for the -40s. |
Quoting AA737-823 (Reply 17): Parking A320s after only 25,000 cycles? |
Quoting AA737-823 (Reply 17): It's a shame, anyhow. Granted, I'd like nothing more than to see every A320 in the NW fleet replaced with new-build MD-90-30's, but that's a pipe dream and I know it. |

Quoting Nitrohelper (Reply 17): now any idea how many cycles are permitted on DC-9s, (any vintage), |
Quoting Norcal773 (Reply 10): Another excuse to keep the DC9's flying even longer. |
Quoting Apodino (Reply 9): I would take this with a grain of salt. Look at the original posters handle. Sounds like a bitter AMFA mechanic trying to stir the pot against NW to me. |

Quoting ExFATboy (Reply 5): I'd imagine someone in NW's accounting department has done a study of 1st-gen A320 repair versus DC-9 fuel consumption, and the numbers favour the DC-9. |
Quoting DfwRevolution (Reply 7): Not really. The 737 service-life is 75,000 cycles, which can be extended with intensive maintenance checks and overhauls. |
Quoting SEPilot (Reply 23): Hey, the NW DC-9's have been declared by God and the Continental Congress to be immune from such mundane factors as fatigue. |
Quoting BEG2IAH (Reply 21): http://www.airweb.faa.gov/Regulatory...a26d6862571570057fa02?OpenDocument |
Quoting ERJ170 (Reply 26): Could some 739s be in the future for NW? Or do they still have some deliveries of A320s/A319 on hold? |
Quoting Lightsaber (Reply 27): Or the fact they were built with 0.008" thicker sheet metal than anyone else would have built a plane under similar stress... they are over built. That costs fuel. But it will keep them in NW's fleet for a long time more! |
Quoting BEG2IAH (Reply 21): You might want to check Table 3 on the following web page: http://www.airweb.faa.gov/Regulatory...a26d6862571570057fa02?OpenDocument Interesting numbers... |
Quoting Mli717fan (Reply 33): I thought those two were part of the same family, if that is the case, why are their life spans so different? |
Quoting Cubsrule (Reply 12): Airbus narrowbodies aren't built for the cycles that DC-9s and 737s are. That's not a judgment at all. It was a business decision by Airbus. |
Quoting Milesrich (Reply 36): Could Jet Blue, USAir, and United be the next carriers to have issues with the structural integrity of the A-320 series. |
Quoting Mli717fan (Reply 33): A330: 40k A340: 20k I thought those two were part of the same family, if that is the case, why are their life spans so different? |
Quoting AA737-823 (Reply 16): I'd like nothing more than to see every A320 in the NW fleet replaced with new-build MD-90-30's, but that's a pipe dream and I know it. |
Quoting Lightsaber (Reply 27): 75,000 cycles is a heck of a lot anyway! |
Quoting Milesrich (Reply 36): European aircraft have a history of wearing out before their time. |
Quoting Milesrich (Reply 36): How in the world does the Wing Box on a modern airplane wear out after only 20,000 cycles? |
Quoting Milesrich (Reply 36): While a Boeing isn't as stout as a Douglas, European aircraft have a history of wearing out before their time. |
Quoting BEG2IAH (Reply 21): Guys, You might want to check Table 3 on the following web page: http://www.airweb.faa.gov/Regulatory...a26d6862571570057fa02?OpenDocument Interesting numbers... BEG2IAH |
Quoting Mli717fan (Reply 33): Also, A330: 40k A340: 20k I thought those two were part of the same family, if that is the case, why are their life spans so different? |
Quoting MD-90 (Reply 42): 20,000 cycles - Boeing 744 20,000 cycles - MD-11 20,000 cycles - A340 |
Quoting Futurecaptain (Reply 46): Douglas built it's planes so well |
Quoting SSTsomeday (Reply 47): What are the merits of the 320 that make it so popular, if it is expected to do only 25K cycles with the 737 doing 75k? The two seem to be both selling equally well. Is the 320 cheaper to operate? Does the durability of the 737 add weight? |
