utilisation, doing a lot of relatively short hops and short turn arounds.
In the last few days, there have been a number of stories about WN
having problems, notably a 1.5m long hole opening in the roof of a
737-300. (15 years old).
Is maintenance frequency dictated on flight cycles, or some hybrid
cycles and age ?
In other words, is it possible that Boeing got its 737-300 certicated
with a maintenance protocol which did not take into account the type of
use that airlines such as Southwest would be making ?
Since WN is one of the first airlines to make such efficient use of
aircraft, it would be one of the first with older aircraft exhibiting
problems that wouldn't happen with legacy carriers whose planes would
have fewer cycles per year of age.
Since the trend is for all airlines to increase aircraft utilisation
rates, is it possible that all narrowbodies would see their maintenance
protocols adjusted to reflect a higher number of cycles per year ?
