GTCP 131-9 Series APU Overhauled/Serviceable Parts
We have been working with the 131-9 series of APUs since we purchased our first 131-9B in 2014 for teardown.
In late 2022 we purchased 131-9A APU P-3747 which was used for teardown. The APU was torn down at TurbineAero’s workshop in Thailand and SV and OH parts came into our stock in April 2023.
Our first teardown was a 131-9B from a Boeing 737-800 aircraft and the APU became too expensive for the airline to repair at a shop visit and was sold for spares recovery. The parts of the APU were sent to Revima-APU in France for re-inspection and certification before coming into Swanaero’s stock in late 2014. All parts have 2014 Revima EASA Form 1 dual release and full traceability.
