Washington: Boeing, the lead integrator on the Boeing B-52H Stratofortress heavy bomber re-engining program, will not physically inspect the pylons on each aircraft, leaving that duty to the US Air Force (USAF).
Jim Kroening, Boeing B-52 Commercial Engine Replacement Program (CERP) manager, said that while the company does not plan to inspect each pylon, Boeing’s teams have been able to visit the programme depot maintenance line. Here they observed the aircraft, with the engines and nacelles removed, and looked at the pylon structure and its attachment to the wings.
Boeing, Kroening said, is replacing the pylon and nacelle as part of integrating new engines onto the B-52H from a to-be-determined supplier. It is important to Boeing to understand how that pylon has interfaced with the wing and which forces come into play there regarding the load.
“We do understand what is contained within the existing nacelle and existing strut,” Kroening said ahead of the Air Force Association’s (AFA’s) annual conference the week of September 14. “Since we are replacing all of that, having a compatible design to that is not really imperative on this program.”
