Hi,
any one know about the cost of maintaining kj200 or 500 and how often it
is to overhaul the engines or flying hours
thank you
I don't know about the details of the schedule and implementation of engine maintenance for a KJ-200/500, but I have some knowledge based on some real-world experience on a similar aircraft type.
There are generally three types of engine maintenance, I will number each one giving a simple designation for each level of maintenance:
1 - light maintenance
2 - moderate maintenance
3 - general maintenance
For each flight, the engine must have level 1 maintenance, generally pre-flight and post-flight. This maintenance is a visual inspection.
There are three types of level 2 maintenance. This level 2 maintenance occurs every 3 months. It is a visual and filter inspection, thermocouple test and compressor washing.
There is another type of level 2 maintenance that occurs every 9 months. It is a visual and filter inspection, thermocouple test, compressor washing, oil change, boroscopy, eddy current on the exhaust clamps, bleed air cleaning, ignition test.
There is another type of level 2 maintenance that occurs every 12 months. It's exactly the same type of maintenance as before.
The last is level 3 maintenance that occurs every number of flight hours. This is the engine overhaul geral, carrying out a complete inspection of the engine. Here the complexity is much greater than level 1 and level 2 maintenance, with more men working on this inspection and the duration is longer, generally taking a period of 90 days compared to the 10 days of level 2 maintenance and 3 days of level 2 maintenance every 3 months that I said earlier.
The three types of maintenance seem to be a standard, the only thing that should change in relation to other aircraft or manufacturers are the main maintenance activities and the interval between each maintenance, some opting for flight hours instead of months.
As for the maintenance cost, this information is certainly something that I would like someone here to comment on, because I have never seen an official PLA budget being released.
