Marsh Brothers Secures Australian King Air Retrofit Deal
CJ Aerospace to install the self-lubricating kits
Marsh Brothers Flap Rollers
Marsh Brothers Aviation’s King Air flap roller kit ready to be installed.

Marsh Brothers Aviation, a Canadian parts designer and builder, has received a contract with Australia's CJ Aerospace to supply a newly developed King Air flap roller kit to Australian operators. Kits will be installed at two maintenance facilities to replace the original roller bearings on King Air 200/300 series aircraft, per the agreement.

King Air bearings often dry out or lose lubrication, which affects performance and reliability. Textron Aviation, the aircraft’s manufacturer, has increased the inspection interval for these components to every three years or 3,000 landings in response to these issues. The upgrade kit eliminates the need for roller greasing and can reduce overall costs associated with replacement and repairs.
