Q - Are OEM drawings for the HRP 5001 TT propeller, or any Government-held technical data, available for release? The Purchase Description does not include blade geometry (section profiles, skew, rake, radial pitch and thickness distribution). If not, is the existing or removed propeller accessible for 3D scanning?
