What is the service cycle or interval of the Landing gear of an A380 and 747-8, i.e how long between service, eg after how many take offs and landings with particular reference to bearing checks and lubrication of the bearings and axles of the wheels

  • $\begingroup$ I'm guessing that this is something done at A or B checks, not at a particular landing/cycle interval. $\endgroup$ – Ron Beyer Jun 10 at 14:03
  • $\begingroup$ Certainly not less than C check, 4000 to 6000 hours depending on the airplane. Airliners only have minor maintenance and inspections (1A, 2A, 3A, etc. - A checks are 500 hours give or take) that can be done on overnights, until C check which is the first time a lot of panels are removed and components get major servicing and functional testing and the plane is down for a week or so. A task like that could also be based on flight cycles and if not set at a level that allows coordination with C check down time, becomes "out of phase" maintenance and is a pain in the butt for the airline $\endgroup$ – John K Jun 10 at 18:22
  • $\begingroup$ 20 wheels and 16 wheels respectively for these two aircrafts on their main landing gears do seem to provide a distributed wait per wheel in the same range as on other aircrafts such as the B777 or the A330. I would say the same maintenance interval as other large aircrafts. $\endgroup$ – user40476 Jun 10 at 20:38
  • $\begingroup$ iata.org/whatwedo/workgroups/Documents/MCC-2015-MIA/…Fin_Impact_of_Extending_or_Reducing_Lease_Term-_Joost_Groenenboom.pdf seems to suggest 10 yearly landing gear shop visits for typical operations for both narrow- and widebodies. $\endgroup$ – Cpt Reynolds Jun 10 at 21:24
