The Pratt & Whitney PW2000 is a series of high-bypass turbofan aero engines with a thrust range from 37,000 to 43,000 lbf (165 to 190 kN). Built by Pratt & Whitney, they were designed for the Boeing 757. As a 757 powerplant, these engines compete with the RB211-535.[1]

Design and development

The first PW2000 series engines, the PW2037, entered service on 757s in 1984. A military version then flew on the Boeing C-17 jet transport in 1991, and another civilian variant on the Ilyushin Il-96 IL-96M variant in 1993.

An improved PW2043 version launched in 1994, offers better reliability, durability and reduced total maintenance cost, along with excellent environmental performance.

The current build standard is the PW2043, providing over 43,000 lbf (190 kN) thrust. The PW2043 provides good fuel efficiency and additional thrust capability at high altitudes and/or elevated temperatures. Current engines can be converted to a PW2043 through minor modification.

Besides the 757, the PW2000 series engines also power the Ilyushin Il-96M and the C-17 Globemaster III military transport, where in its military guise, designated as the F117-PW-100.

On October 16, 2008 the NTSB recommended that the FAA issue urgent new inspection procedures for aircraft (Boeing 757 models) using the PW2037 model of the engine. This came about after an investigation started after the engine failed during an August 2008 Delta Air Lines flight out of Las Vegas, Nevada. The NTSB recommended that the FAA order PW2037 engines removed from service for inspections if they have more than a threshold of flight hours or flight cycles, and be reinspected at regular intervals. The specific threshold was not named but was recommended to be significantly less than the number of flight hours (10,880 flight hours) or flight cycles (4,392 cycles) of the engine that failed in August 2008.
