Design and development
Pratt & Whitney designed the engine with minimum complexity to significantly reduce maintenance costs and achieve weight and fuel consumption savings. However, tests revealed that the initial five-stage high

CFM56-5
The CFM International CFM56 (U.S. military designation F108) series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of . CFMI is a 50–50 joint-owned company of Safra ...
. To address the problem, Pratt & Whitney re-certified an updated design utilizing a six-stage high compressor designed by
MTU Aero Engines in order to achieve promised performance. The German company manufactured the high-pressure compressor and the low-pressure turbine. The HP compressor is driven by a single-stage turbine. On the LP spool a three-stage turbine drives a single-stage fan and a four-stage LP compressor.
The engine made its first flight August 21, 2000 on a test aircraft flown from

confirmed an order for 15 Airbus A318 aircraft, for a total of 34 engines (30 installed and 4 spares) powered by PW-6000 engines on 15 August 2005. In addition, LAN signed with Pratt and Whitney to power up to 25 option aircraft. If LAN exercises all options it would mean an additional 56 (50 installed and six spare) engines.
Prior to the LAN order, 84 CFM56-5 powered Airbus A318 aircraft had been ordered, with 28 currently in service .
