Boeing’s 777-9 Certification Program Paused to Address Engine Component Cracks

Aviation Week reports, “Cracks in engine attachment components that have stalled Boeing’s 777-9 certification program were found in a fourth test aircraft that has not flown in nearly three years, Aviation Week has learned. The latest discovery, on WH004, is expected to help narrow down Boeing’s investigation into the failures in the thrust links—assemblies that connect the airframe with the aircraft’s GE Aerospace GE9X engines.

Demand for Freighters Expected in Years to Come

Aviation Week reports that Airbus is predicting that shippers “will need 560 widebody freighters of more than 80-ton capacity from 202-41. Boeing expects demand for 515 widebody freighters over the same period.” Although much of this demand will reportedly “be satisfied by new-make cargo aircraft…new ventures are moving steadily toward converting Boeing 777s to meet the requirements for heavy cargo aircraft.”

Boeing Pauses 777 Testing After Engine Issue

FlightGlobal reports that The Boeing Company “has halted its 777-9 flight-test programme due to a problem involving a flight-test aircraft’s GE Aerospace GE9X turbofan, prompting engine evaluations by GE.” Both companies confirm “the flight-test pause but provide few details about the problem, leaving the extent of the issue and its potential impact on the 777-9’s certification timeline unclear.” GE says it “discovered the problem, later found to involve temperatures, following a borescope inspection.” Boeing’s 777-9 certification program “is already substantially delayed, with Boeing most recently – in April – pushing its expected first 777-9 delivery back two years, to 2025.”

Boeing Comes Up With Fix to Strengthen 777 Engine Covers

Citing sources familiar with the matter, the Wall Street Journal reports that The Boeing Company has come up with a fix to strengthen engine covers similar to the one that disintegrated on a United Airlines 777 jet after it took off from Denver in February. FAA Administrator Steve Dickson said in congressional testimony Wednesday that Boeing and Pratt & Whitney are working with the agency to prevent the breakup of engine covers.
