Each subject within the SRM uses a four-element numbering system. True. False.

What is the first document to use to assess damage on the aircraft structure?. Aircraft Operation Manual. Pilot's Handbook. Structure Repair Manual. Maintenance Manual.

Where is general information or information applicable to more than one chapter included in the SRM. Chapter 50. Chapter 51. Chapter 52. Chapter 53.

In the "MOD/Definition Comparison" service, what does the "Aircraft status" criterion allow you to filter by?. The family of the aircraft. The type of aircraft. The status of the aircraft (e.g. delivered or to be delivered). The owner ICAO code of the aircraft.

What is the primary purpose of the Structure Repair Manual (SRM)?. To provide a list of all Airbus aircraft models. To provide guidelines on how to repair aircraft. To provide a history of Airbus. To provide a list of all aircraft manufacturers.

How is the SRM organized?. By aircraft model. By type of damage. By ATA specification. By date of publication.

What is the significance of 'Allowable Damage'?. It indicates damage that requires immediate repair. It indicates damage that can be ignored. It indicates damage that can be temporarily tolerated without immediate repair. It indicates damage that has been repaired previously.

What does a 'gouge' refer to?. A line of damage. A damage area resulting in a cross-sectional change. A mark caused by a sharp object. A series of scratches.

What causes 'corrosion'?. Physical impact. Chemical or electro-chemical effect. Exposure to high temperatures. Regular wear and tear.

Which factors determine the type of surface protection for components?. Material and Function. Material, Function, and Location. Function and Location. Only Material.

Which of the following is NOT an exception to external areas having surface protection?. Leading edges of slats. APU exhaust. Wing flaps. Cabin Pressurization Control System Outflow Valve.

What is the definition of corrosion?. Enhancement of metals. Destruction of metals by chemical effects. Strengthening of metals. Natural wear and tear of metals.

Which of the following is NOT a step necessary for satisfactory control of corrosion?. Regular maintenance. Applying heat. Initial identification of corrosion. Complete removal of corrosion when it occurs.

Which of the following is NOT a corrosive agent?. Acids. Alkalies. Pure water. Salts.
