Introduction
April 23, 2018, © Leeham News: Even before last week’s Southwest Airlines accident raised the focus on aircraft engines, industry officials were becoming worried that problems with engines powering the Boeing 747-8, 787, 737 MAX and Airbus A320neo may lead to stricter certification standards by regulatory authorities. There is also emerging evidence that the issues with the Rolls-Royce Trent 1000 on the 787s may negatively impact Airbus’ sales efforts with the A350. The A350 is powered by an entirely different RR engine, the Trent XWB, which by all accounts has had a virtually trouble-free entry into service. But it’s a Rolls-Royce engine and airlines affected by or watching RR’s response to the Trent 1000 problems are skeptical about the Trent XWB, LNC is told.
Summary
  • How long will it take for the FAA and EASE to restore full ETOPS for the 787?
  • Concerns emerge that regulators may be more restrictive of ETOPS for new engines powering new planes, with the Boeing 777X next up.
  • Impact seen on reception of Rolls-Royce engines on Airbus A330neo and A350.
  • What do the engine problems mean for the Boeing NMA?
