MT breathes new life into old propellers

July 31, 2012

Sourcing parts is always difficult when you own a vintage airplane. Things just got a little easier for certain propellers, thanks to a new release from MT-Propeller. The company will begin producing two-blade ground-adjustable aluminum propellers for the vintage market.

The new 5400-series blades are meant as a direct replacement for those previously produced by the Standard Steel Propeller Company. These blades are found on many vintage aircraft, especially those with radial engines of up to 450 horsepower, and may be 10 feet in diameter.

MT’s new propeller will be available with a new steel hub. The entire assembly is type certificated, and in most cases eligible for direct replacement. According to Aviation Foundation of America President Greg Herrick, who helped MT with the project, the product will be comparable to or even less than vintage blades.

“I can’t tell you how important this is for the continued airworthiness of the mostly vintage aircraft which use these blades,” he said. “MT has done a huge service for aviation in producing these blades.”
