Challenge

An aerospace MRO supplier needed AMS-R-83485 compliant FKM O-rings for a fuel pump overhaul with an AOG (aircraft on ground) deadline of 72 hours.

Solution

We supplied certified AMS-R-83485 FKM O-rings from stock with full batch traceability and material certification.

Result

The parts were delivered in 48 hours with complete documentation, allowing the fuel pump to be returned to service ahead of the AOG deadline.

Details

The MRO supplier was supporting a regional airline with an AOG situation caused by a leaking fuel pump. The pump manufacturer specified AMS-R-83485 FKM O-rings in AS568-210, -214 and -325 sizes.

We maintained stock of these exact sizes in AMS-R-83485 brown FKM. Each lot was traceable to the raw material batch and compound formulation. Certificates of conformance and batch test reports were provided with the shipment.

Because the order was placed at 10:00 AM local time on a Tuesday, the parts were picked, inspected, documented and shipped via express courier the same day. They arrived at the MRO facility on Thursday morning.

The fuel pump was successfully overhauled and returned to the airline by Friday afternoon — 12 hours ahead of the AOG deadline. The customer added us to their approved vendor list for all future AMS-R-83485 seal requirements.
