# Create Maintenance Check Type

> Learn how to create maintenance check types for tracking aircraft service requirements in FlightWise

Maintenance check types define the recurring maintenance requirements for your aircraft fleet. This guide shows how to create check types that will be used to track when aircraft need service.

## Creating a Check Type

Follow these steps to create a new maintenance check type:

<video autoPlay muted loop playsInline controls className="w-full rounded-xl aspect-video" src="https://docs-cdn.aviationwise.io/admin-aircraft-maintenance-check-types-create-type.mp4" />

1. **Navigate to Check Types**
   * Go to the Aircraft page in the administrator portal
   * Look for "Check Types" in the aircraft sidebar menu
   * Click on "Check Types" to open the management page

2. **Start Creation Process**
   * Click the "Add Type" button
   * A dialog window will appear with the check type form

## Configuration Fields

### Basic Information

3. **Enter Check Type Details**

   **Name** (Required)

   * Enter a clear, descriptive name
   * Examples:
     * "100 Hour"
     * "Annual"
     * "50 Hour Oil Change"
     * "Pitot-Static Check"

   **Description** (Optional)

   * Add additional details about the check
   * Include regulatory references if applicable
   * Example: "Required under Part 91.409 for commercial operations"

### Interval Configuration

4. **Set Maintenance Intervals**

   Configure when this maintenance is due by setting one or both intervals:

   **Hours Interval**

   * Enter the flight hour interval
   * Used for usage-based maintenance
   * Examples:
     * 50 (for oil changes)
     * 100 (for inspections)
     * 2000 (for overhauls)

   **Days Interval**

   * Enter the calendar day interval
   * Used for time-based requirements
   * Examples:
     * 365 (annual inspection)
     * 730 (24-month checks)
     * 90 (quarterly inspections)

   **Both Intervals**

   * Some checks require both hours AND days
   * System will use whichever comes first
   * Example: Annual/100-hour inspection

5. **Save the Check Type**
   * Review your entries for accuracy
   * Click "Save" to create the check type
   * The type is now available for assignment to aircraft

## Common Check Type Examples

### Hours-Based Only

| Check Type          | Hours Interval | Days Interval |
| ------------------- | -------------- | ------------- |
| 50 Hour Oil Change  | 50             | -             |
| 100 Hour Inspection | 100            | -             |
| Engine Overhaul     | 2000           | -             |

### Calendar-Based Only

| Check Type         | Hours Interval | Days Interval |
| ------------------ | -------------- | ------------- |
| Annual Inspection  | -              | 365           |
| Pitot-Static Check | -              | 730           |
| ELT Certification  | -              | 365           |
| Insurance Renewal  | -              | 365           |

### Combination Checks

| Check Type          | Hours Interval | Days Interval | Note                  |
| ------------------- | -------------- | ------------- | --------------------- |
| Annual/100 Hour     | 100            | 365           | Whichever comes first |
| Progressive Phase 1 | 50             | 90            | Both limits apply     |

## After Creating Check Types

Once check types are created, you can:

1. **Assign to Aircraft**
   * Go to specific aircraft profiles
   * Add check items based on these types
   * Set initial due values

2. **Manage Existing Types**
   * Edit names or intervals
   * View which aircraft use each type
   * Track compliance statistics

3. **Use in Reports**
   * Generate maintenance forecasts
   * View upcoming requirements
   * Track maintenance costs by type

## Best Practices

### Naming Conventions

* Use industry-standard terminology
* Include interval in name if helpful (e.g., "100 Hour")
* Be consistent across your fleet
* Avoid abbreviations that might confuse staff

### Interval Settings

* Verify intervals match regulatory requirements
* Consider manufacturer recommendations
* Account for your operational tempo
* Build in appropriate margins for scheduling

### Documentation

* Use descriptions to reference:
  * Regulatory requirements (Part 91, 135, etc.)
  * Manufacturer service bulletins
  * Internal policies
  * Special procedures

The check type system provides the foundation for comprehensive maintenance tracking, ensuring your fleet remains airworthy and compliant with all requirements.
