Routine non-destructive testing (NDT) revealed cracks in a key aluminium airframe beam on E model CC130. Consequently, the CF Aeronautical Engineering community issued an operational restriction to all squadrons flying these aircraft that cabin pressure differentials were to be maintained a no more than 10psi (pounds per square inch). At service ceilings ranging from 24,000 ft to 28,000 ft, a 10psi cabin pressure differential produces corresponding cabin altitudes ranging from 8,000 ft to 10,000 ft. Such cabin altitudes have been implicated in 2 recent physiological incidents. Of the 20 CC130 aircraft based at 8 Wing (CFB Trenton), 17 are the affected E models. The 8 Wing Surgeon requested that DCIEM monitor percent arterial oxyhemoglobin saturation (% SaO2) with a view to quantification of this areo-medical problem and possible countermeasures to protect the crews flying these aircraft. A DCIEM scientist accompanied an augmented 9-man crew on a routine re-supply mission from 8 Wing to Zagreb and return. During this mission, SaO2 readins (at ground level, 8,000 ft and 9,000 ft) were obtained from all 9 crewmembers, as well as the DCIEM scientist. TRUNCATED
