✍️ Sample A&P Questions & Answers
1. What does a variable-displacement hydraulic pump do when system demand is low?
A variable-displacement pump adjusts its output volume (stroke) to match demand, maintaining pressure while minimizing power consumption.
2. A technician needs to find approved repair procedures for a damaged main structural member on a specific large aircraft. Which of the following documents should be consulted first?
The Structural Repair Manual (SRM) is the primary document issued by the aircraft manufacturer that contains detailed information, limitations, and approved procedures for repairing the aircraft's primary and secondary structures. While AC 43.13-1B provides acceptable techniques for non-pressurized aircraft when no manufacturer instructions are available, the SRM is always the first and authoritative source for a specific aircraft model.
3. Which document specifies maintenance requirements for a specific aircraft?
The Aircraft Maintenance Manual (AMM) is the definitive document provided by the aircraft manufacturer, containing detailed instructions for all maintenance, inspection, troubleshooting, and repair procedures specific to that aircraft model. It ensures that maintenance is performed correctly and consistently, which is essential for maintaining the aircraft's airworthiness and compliance with design specifications. Other documents like the Pilot's Operating Handbook serve different operational purposes.
4. What is the function of the 'beta range' on a turboprop propeller control system?
The beta range allows the pilot to manually control blade pitch below the normal governing range, enabling ground fine pitch, zero thrust, and reverse pitch for ground maneuvering.
5. Per 14 CFR Part 43, what action is required after performing maintenance on an aircraft fuel system that could affect airworthiness?
After fuel system maintenance, the mechanic must perform an operational check of the repaired portion, confirm airworthiness, and make a proper maintenance record entry per 14 CFR 43.9 before return to service.
6. Which of the following defines the imaginary vertical plane from which all horizontal measurements of arm are taken for weight and balance purposes?
The Datum is an imaginary vertical plane or line established by the manufacturer from which all horizontal distances (arms) are measured for weight and balance calculations. Its location is specified in the aircraft's Type Certificate Data Sheet (TCDS) or flight manual.
