C-130 Allison Maintenance

C-130 technician up on maintenance stand working on one of the four Allison T56 turboprop engines ... Nha Trang, South Vietnam 1972. Engine cowlings are wide open … notice the holes for the many fasteners along the edge of the openings. These guys did fantastic work … I never recall having a significant problem with an engine on the C-130. Each Allison could provide 4,350 shaft horse-power. Interestingly similar engines were used to generate power on destroyer class ships in the US Navy. Rolls-Royce took over Allison production in the late 1990’s.
