Unsafe Condition

Failure of the seal of the hydraulic pump shaft could cause hydraulic fluid contamination of the engine oil system, leading to clogging of the hydraulic pump drain system and subsequent engine accessory gearbox oil contamination, which could result in an in-flight engine shutdown.

Required Actions

Conduct flow checks of the hydraulic pump drain system to ensure no clogging, correct any discrepancies found, and replace the existing seal of the accessory gearbox with an improved seal assembly to terminate repetitive flow checks.
