331-200 & 331-250 APU Serviceable Parts
3810214-5 Lower Plenum
3810213-10 Upper Plenum
In 2021 we continued to invest in this APU type, used on the Boeing 757 and 767 now much in demand as cargo aircraft.
In June 2021 we purchased 331-200ER APU serial number P-1601 which was torn down at Dublin Aerospace’s workshop. We have also just purchased APU s/n P-1555 which is now at Dublin Aerospace’s workshop for disassembly, parts are due in stock at Swanaero later in 2021.
Our involvement in this product line started in 2010 when we had our first 331-200ER APU parted-out. The APU was purchased from UK operator Thomson Airways and parts were inspected at H+S Aviation and Piedmont.
In 2013 we purchased 331-200ER s/n P-114C in disassembled condition. It was sent for teardown and parts inspection at Revima-APU.
In 2015 we purchased 331-250F s/n P-174 which was torn down at Dublin Aerospace.
In 2016 we purchased a package of parts from a 331-200ER which was torn down at Dublin Aerospace.
Also in 2016 we purchased 331-200ER serial number P-1394 which was torn down at Dublin Aerospace’s workshop. Certain LRUs were also repaired at Piedmont.
In 2019 we purchased 331-200ER APU serial number P-2121 for teardown to parts.The APU was sent to Dublin Aerospace’s workshop for disassembly and parts inspection. Certain LRUs were also set to TurbineAero and Piedmont for test and repair.
