FAA Powerplant Written Practice Test

What checks are usually included in the inspection of pneumatic starters by maintenance technicians?

1. Fuel pump efficiency

2. Oil level and magnetic drain plug condition

3. Compressor performance

4. Battery voltage status

The correct answer is: Oil level and magnetic drain plug condition

Maintenance technicians typically focus on specific checks when inspecting pneumatic starters. The correct answer, which involves oil level and magnetic drain plug condition, is essential because pneumatic starters often rely on lubrication to function effectively. Ensuring the proper oil level is critical to maintaining the starter's mechanical integrity, cooling, and effective operation. The magnetic drain plug plays a crucial role in detecting any metal particles or debris that could indicate wear or potential failure within the starter system. Other checks like fuel pump efficiency, compressor performance, and battery voltage status, while important in their own contexts, do not directly correlate to the essential maintenance tasks associated with pneumatic starters. Instead, they pertain more to different systems, such as fuel or electrical systems, rather than specifically focusing on the health and functionality of a pneumatic starter itself.
