Pratt & Whitney should conclude validation tests within six weeks on 19 alternative life-limited parts for the CFM International (CFMI) CFM56-3 engine.
The tests mark the next major step in P&W’s potentially game-changing attempt to introduce parts manufacturing approval (PMA) alternatives to CFMI’s aftermarket business.
PMA parts are typically reverse-engineered items that sell for a large discount compared to aftermarket original equipment manufacturer products. Engine companies typically make most of their profit on aftermarket sales, so P&W’s presence in the PMA business could be a de-stabilizing force for the engine industry’s classic business model.
P&W will seek to gain certification approvals from the US FAA in mid-2008 for the 19 life-limited parts, Matthew Bromberg, VP and general manager of P&W’s Global Material Solutions business.
The company has already received FAA approvals for a batch of expendable engine parts, and one component -- the high-pressure turbine shroud – is in operation with P&W’s European launch customer Jet2.com.
The company launched the PMA campaign for the CFM56-3 about 18 months ago. Jet2.com, United Airlines and an undisclosed Chinese carrier have signed on as launch customers on each of three continents – Europe, North America and Asia.
P&W’s next goal is to establish the credibility of its PMA parts strategy with lessors, whose acceptance is vital to gain universal usage across the industry, Bromberg says. The company has set a 12 to 18 month timeline satisfying this goal, he adds.
