Which description accurately reflects the method used to remove an engine?

• A. Lowering the engine with a forklift while the engine remains mounted.
• B. Using a sling and hoist arrangement to lower the engine into its transportation dolly.
• C. Lowering the engine using a hydraulically operated installation stand only.
• D. Lifting the engine with no means to guide it.

Answer: (C)

Controlled movement with proper support and alignment is essential when removing an engine. A hydraulically operated installation stand provides a dedicated cradle for the engine and delivers precise vertical lowering with built‑in guides. This keeps the engine stable, minimizes swing and misalignment, and makes it easier to line up with a transport dolly or installation points, reducing the risk of damage to the engine and aircraft.

Other methods lack that combination of support and guided movement. Lifting or lowering with a forklift while the engine is still mounted can create imbalance and clearance issues. Using slings and a hoist adds handling steps and potential for swing or misalignment, and attempting to lower without any guiding means is unsafe. The hydraulically operated installation stand is the best option because it provides controlled, aligned support throughout removal and transfer.
