Equipment Overview

The Houchin C690-90 is a diesel-driven aircraft ground power unit used to supply electrical power to parked aircraft for servicing, maintenance, and pre-flight operations. Houchin Aerospace GPUs are widely used across airports, FBOs, and MRO facilities internationally, and the platform has an established support and parts base. This unit is trailer mounted for towed positioning on the ramp, rated 90 SV, and weighs 2,635 kg.

The unit is offered non-operational. Reported faults are uneven voltage transmission and problematic power transmission, and the unit requires a battery. Because stable, clean voltage output is the core function of a ground power unit, these faults render the unit unsuitable for aircraft use until properly diagnosed and repaired. The fault has not been fully diagnosed in this listing, and the underlying cause, repair scope, and parts requirement are unknown and must be assessed by the buyer. The hour meter reads 13,577 hours, and general wear consistent with a 2005-build unit at those hours should be expected. Sold as-is, where-is, with no representation that the unit can be economically repaired.
