Service Bulletin Managing the APS3200 life limit The main rotating parts of the APS3200 APU, one of the auxiliary power units for the Airbus A320 aircraft family, are managed under a life management plan. APU manufacturer Pratt & Whitney Canada has implemented fixed life limits in the Engine Manual: a limit of 50,000 cycles for the load compressor impeller and the power section impeller and 32,000 cycles for the first-stage and second-stage turbine disk. Parts exceeding these limits must be replaced – a task we have broad experience with. The corresponding Services Bulletin (P&WC S.B. No. 320150) requests all operators to replace the affected parts within a specific time frame. Parts with 15,000 APU cycles or more above the fixed life limits constitute the most urgent cases. They must be replaced within the next 500 APU cycles or three months, whichever comes first. We are prepared to provide the necessary technical support regarding all questions concerning the APS3200.
