Pratt & Whitney (P&W) anticipates that the PurePower PW1700G and PW1900G engines for Embraer's next generation E-Jets will be certified in "late 2016", say executives.

This is in-line with the airframer's plan for entry-into-service of the aircraft family in 2018, says Bob Saia, vice-president of the next generation product family in P&W's commercial engine programmes, at a media event in Palm Beach on 11 April.

Embraer launched the second generation E-170 and E-190 family with the P&W geared turbofans in January. It will equip the aircraft with new wings and fly-by-wire avionics, as well.

The new E-170 family will come with the PW1700G, which is a de-rated version of the PW1200G for the Mitsubishi Aircraft MRJ regional jet, and the new E-190 family will come with the PW1900G, which is a de-rated version of the PW1500G for Bombardier's CSeries, says Saia.

The PW1700G will have a 142.2cm (56in) fan with maximum thrust of 17,000lb and the PW1900G will have a 185.4cm (73in) fan with maximum thrust of 24,000lb, he says.

The PW1200G has a maximum thrust of 17,000lb and the PW1500G of 23,000lb.

Saia says that P&W is staffing its E-Jet engine team currently, while it waits for Embraer to formally launch the aircraft programme.

Certification of the MRJ engine is on-track for mid-2014, says Saia. P&W is about halfway through its testing programme for the engine, with certification tests slated to begin "mid-year", he adds.

The MRJ's first flight will likely be delayed from this year due to the engine certification, which was previously scheduled for mid-2013.
