Problem 1 - Accounting

Question

Indicate whether each of the following costs of an airplane manufacturer would be classified as direct materials cost, direct labor cost, or factory overhead cost: a. Controls for flight deck b. Aircraft engines c. Depreciation of welding equipment d. Welding machinery lubricants e. Salary of test pilot f. Steel used in landing gear g. Wages of assembly line worker h. Tires

Step-by-Step Solution

Answer

Direct Materials: a, b, f, h. Direct Labor: g. Factory Overhead: c, d, e.

Step 1: Understanding the Cost Categories

There are three main cost categories: 1. **Direct Materials Cost**: The raw materials that are directly traceable to the manufacturing of a product. 2. **Direct Labor Cost**: The wages paid to workers who are directly involved in the production process. 3. **Factory Overhead Cost**: Indirect costs that are not directly traceable to a single product, including facility costs like utilities and salaries of supervisors.

Step 2: Classifying Controls for Flight Deck

Controls for flight deck are specific components used to build the airplane. They can be directly traced to the final product, so these costs are categorized as **Direct Materials Cost**.

Step 3: Classifying Aircraft Engines

Aircraft engines are crucial components directly incorporated into the aircraft and traceable to the product. Thus, these costs are classified as **Direct Materials Cost**.

Step 4: Classifying Depreciation of Welding Equipment

Depreciation on welding equipment is an expense that refers to the wear and tear of machines used in production, which cannot be traced back to a specific product. Hence, it is categorized as **Factory Overhead Cost**.

Step 5: Classifying Welding Machinery Lubricants

Lubricants for machinery are necessary for maintaining equipment used in production but aren't directly traceable to the final product. These costs fall under **Factory Overhead Cost**.

Step 6: Classifying Salary of Test Pilot

The test pilot's salary is part of the costs needed to ensure the plane functions properly and is not directly tied to production. It is part of **Factory Overhead Cost**.

Step 7: Classifying Steel Used in Landing Gear

Steel for landing gear is a raw material directly used in producing the airplane, making it a **Direct Materials Cost**.

Step 8: Classifying Wages of Assembly Line Worker

Assembly line workers are directly involved in the manufacturing of the airplane. Their wages are classified as **Direct Labor Cost**.

Step 9: Classifying Tires

Tires are specific components added to the aircraft, making them part of the **Direct Materials Cost**.

Key Concepts

Direct Materials Cost

Direct materials cost refers to the raw materials that are essential in manufacturing a product and can be distinctly identified with the finished goods. In the context of an airplane manufacturer, these materials are crucial components that end up as parts of the aircraft itself.

Some examples include:

• Controls for the flight deck: These are specific parts used in the construction of the aircraft and can easily be linked to the final product.
• Aircraft engines: These are one of the most significant components of an airplane and are directly incorporated into the machinery.
• Steel used in landing gear: This is a fundamental raw material used in forming critical parts of the aircraft.
• Tires: These are essential for the airplane and can clearly be traced back to the product.

All these materials are needed for the production of the airplane and can be accounted for at the end of the process due to their direct traceability. Understanding this category helps in accurate budgeting and cost measurements specific to production materials.

Direct Labor Cost

Direct labor cost is the expense of wages paid to workers who are actively and directly involved in the creation of a product. These are employees who physically work on converting raw materials into finished goods, hence their wages are directly associated with the product.

In airplane manufacturing, direct labor costs might include:

• Wages of assembly line workers: These individuals work on the production line, assembling various parts of the airplane, making their labor directly linked to production.

Direct labor differs from indirect labor as it contributes immediately to the fabrication of end products.

Knowing direct labor costs is crucial in calculating overall production expenses and setting competitive pricing for the finished airplanes.

Factory Overhead Cost

Factory overhead cost encompasses all the indirect costs incurred during the manufacturing process that are not directly traceable to a specific product. These costs are essential in supporting the production process and maintaining the manufacturing environment but are distributed among all produced items.

Examples of factory overhead in airplane manufacturing include:

• Depreciation of welding equipment: Refers to the reduced value of the equipment over time due to usage, essential for production but not tied to any single aircraft.
• Lubricants for welding machinery: Necessary for ensuring machines run smoothly but does not end up in the final product.
• Salary of the test pilot: Although the test pilot’s activities ensure the product functions well, their salary is not directly traceable to the manufacturing stage.

These costs contribute to the overall environment and facilitation of production but require allocation across multiple jobs or units for cost-effective manufacturing. Accurately recognizing factory overheads assists in precise financial reporting and overhead control.
