Difficulty: EasyDirect Fact Retrieval

During routine pre-flight inspections of utility helicopters, technicians verify the intermediate gearbox oil level through a visual sight glass on the tail boom. Under normal operating conditions, the lubricant is amber and clear. If inspection reveals a dark brown or milky fluid, ground crews must completely drain and flush the gearbox assembly prior to approving the aircraft for flight.

Statement: Ground crews are required to drain and flush the intermediate gearbox assembly if the inspection fluid appears dark brown or milky.
