Developing Engine PMAs Despite OEM Resistance

A PMA producer sees uptick in interest outside U.S.

According to the U.S. Producer Price Index, in the 17 years from 1999-2016, the prices of engines and engine parts increased 17% after adjustment for general inflation, or 1% per year in real terms.

It’s no wonder airlines are still interested in alternatives to new engine part prices, including used parts and PMAs (parts manufacturer approval). Jet Parts Engineering had 38 PMAs approved in the first half of 2017 and is “looking to add over 100 products annually,” says Jeff Dark, vice president sales and marketing.

Although cost saving depend on part and market, Dark estimates that most “test and computation” PMA parts--newly designed parts that have to prove their suitability--save 35-50% “at minimum.”

PMA parts have thus shown resiliency in growth and acceptance globally, despite OEM strategies, Dark says. But OEMs are becoming ever more aggressive to block them. “Fortunately, there are worldwide customers that understand the competition PMA brings to the aftermarket,” he says.

The Jet Parts Enginering marketer says non-U.S. markets continue to expand as operators see both cost savings and the quality and improved performance PMA parts can bring. He describes these non-U.S. markets as “burgeoning, but still emerging.”

“Challenges like PMA-exclusive leasing agreements and OEM strategy always exist, but overall we are pleased with the direction PMA acceptance is trending internationally,” he says.

Jet Parts’ portfolio of engine parts are all considered non-critical and will continue to be “for the time being,” Dark says. “We are developing parts for various engine families including CF6, CFM56, CF34, PW4000 and V2500.”
