What type of maintenance does an f-22 require to keep operating? Is it the same like for a car? Oil,Filter etc

We all know the maintenance procedure for a car.





As for the F-22 it has Integrated Maintenance Information System (IMIS) integrates the Tech Order Data (TOD), maintenance forms, the aircraft itself to provide the maintainer a single source of maintenance information.





There are three main components to the F-22's IMIS:





1-The Portable Maintenance Aid (PMA)





2-The deployable, squadron-level Maintenance Support Cluster (MSC),





3-The F-22's back shop counterpart, the Maintenance Work Station.

Where you might take your car in for a ';14-point'; service visit, the F-22 would have more like 2,400 points. All high-performance jet airplanes require several crew members dedicated to inspection and maintenance.What type of maintenance does an f-22 require to keep operating? Is it the same like for a car?

Might require different checks, ie. maintenances, based on the number of cycles (landings and takeoffs).





For commercial we have anything from minor to major checks. These are known by letters of the alfabet from A-M or more.





I typically oversee such things as C or M checks, in my job as an airline buyer.





Indeed.
f-22 = aircraft that flies, develops more power, supports more Gs and does not roll on a flat surface for optimal performance.





car=usually has 4 wheels, never exceeds 1.5 Gs, has braking system that can stop the car no matter what the speed in 0.5 km.


does not fly. usually rolls on flat paved surface for optimal performance





now for actual list of what you need to do to keep it flying:





***all systems have usually 2 or more redundancies that need to be checked as well.





-electronics, GPS, RADAR, TACAN, MFD functions.


- Engines~surface check, ie: surface of compressor blades exhaust coating, etc.


Also check fuel injectors, fuel line, hydraulics, gear hydraulics, flaps hydraulics, batteries, starters, all control surfaces.


Lights, brakes, wheels for wear and tear, ejection seat, de-icing equipment, and also internal structure/airframe, for metal fatigue, reapply radar absorbent paint when necessary. ( i doubt it though)





and thats minimally. I'm no expert only a normal pilot who flies cessnas and have been around f-15s for awhile.
It definitely uses synthetic oil because of the temperature extremes encountered. This was the motivation behind fighter pilot Al Amatuzio developing the first synthetic engine oil to meet API specs for automotive use in 1972-- Amsoil.
