Scheduled Fan Blade Lubrication requirement on the PW307D engine, due to unscheduled vibration events occurring in the field.
This maintenance task is now required to be completed every 1600 engine hours and is intended to prevent unscheduled engine vibration issues.
Although this process is not new, the scheduled requirement is. During normal operation, the lubricant can become contaminated or worn away, preventing the fan blades from sliding smoothly into the correct position, causing blade misalignment and engine vibrations. How long an engine can operate before this becomes an issue depends on the environment the aircraft is operated in. The process involves removing the Fan Blades from the engine (special tooling required), lubricating the Fan Blade Root, and reinstalling them.
