Technical Directives
Manage airworthiness directives and service bulletins for your aircraft fleet.
1 What's on this page
The Technical Directives page provides centralised management of regulatory and manufacturer-issued directives affecting your aircraft, engines, propellers, and components. Track compliance requirements, monitor due dates, and maintain comprehensive documentation for all active and historical directives.
Key Features
- Directive types: Manage both Airworthiness Directives and Service Bulletins
- Flexible applicability: Apply to airframes, engines, propellers, or specific parts
- Compliance scheduling: Set initial and recurring maintenance intervals
- Aircraft assignment: Specify which aircraft, engines, or propellers are affected
- Document management: Attach supporting documents and instructions
- Status tracking: Monitor active directives and view deactivated history
Page Areas
- Search Bar: Top-left search for code, title, notes, and other fields
- View Toggle: Centre toggle between Active and Deactivated directives
- Action Button: Top-right dropdown to create new directives
- Filters: Filter by type, category, date range, and component
- Main Table: Sortable list of directives with key information
Airworthiness Directives (ADs) are regulatory requirements issued by aviation authorities and must be complied with. Service Bulletins (SBs) are manufacturer recommendations that may be mandatory or optional depending on your operations.
Both types are tracked in this page with the same compliance monitoring tools, but ADs are visually distinguished with a red badge for priority identification.
2 Searching and filtering directives
Use the search bar at the top-left to quickly locate specific directives. Search works across multiple fields including code, title, notes, and applicable components.
Filter Options
The filter panel below the search bar provides advanced filtering:
- Type: Filter by Airworthiness Directive or Service Bulletin
- Category: For Service Bulletins, filter by category (Alert / Mandatory, Recommended, Optional, Informational)
- Date Range: Filter by published or effective dates using the period selection
Click the info icon () next to the search bar to see all searchable fields.
3 Primary workflows
3.1 Create a new airworthiness directive
Use this workflow when you receive a new AD from an aviation authority that applies to your fleet.
Steps:
- Click the Submit new technical directive dropdown button in the top-right
- Select Airworthiness Directive from the menu
- In the window that opens, complete the General Information section:
- Code: Enter the AD reference number (e.g., "2023-15-04")
- Title: Enter the AD title or subject
- Published Date: Select when the AD was issued
- Effective Date: Select when the AD becomes mandatory
- Notes: Add any supplementary information, supersession actions, or references
- Complete the Scope section:
- Select the Component Type (Airframe, Engine, Propeller, or specific part types)
- If a part type is selected, choose the specific part from the dropdown
- In the Applicable Aircraft/Engines/Propellers card, specify which items in your fleet are affected
- Set up the Compliance Schedule:
- Define the Initial maintenance interval (first compliance deadline)
- If recurring, define the Recurring maintenance interval
- If applicable, check Has terminating action and describe the action that permanently resolves the requirement
- In Supporting Documents, upload any AD documents, instructions, or related files
- Click Save to create the directive
3.2 Create a service bulletin
Use this workflow when you receive a service bulletin from a manufacturer that you want to track.
Steps:
- Click the Submit new technical directive dropdown button
- Select Service Bulletin from the menu
- Complete the General Information section (same as for ADs, with the addition of):
- Service Bulletin Category: Select Alert / Mandatory, Recommended, Optional, or Informational
- Complete the Scope, Compliance Schedule, and Supporting Documents sections following the same process as for Airworthiness Directives
- Click Save
3.3 Edit an existing directive
Use this workflow to update directive details, change applicability, or adjust compliance intervals.
Steps:
- Locate the directive in the Active directives table
- Click the blue Edit button () in the first column
- Update any fields in the window that opens
- Click Save to apply your changes
3.4 View directive details
Use this workflow to review complete information about a directive without editing.
Steps:
- In the directives table, click the directive Code (it appears as a blue button)
- A read-only window opens showing all directive details including:
- General information and dates
- Scope and applicability
- Compliance schedule and intervals
- Assigned aircraft, engines, or propellers
- Supporting documents
- Last modification details
- Click Close or the X to exit the window
3.5 Deactivate a directive
Use this workflow when a directive is superseded, no longer applicable, or cancelled by the issuing authority.
Steps:
- Locate the directive in the Active directives table
- Click the red Deactivate button () in the last column
- In the confirmation window:
- Enter a Reason for deactivation (e.g., "Superseded by AD 2025-01-05" or "Aircraft no longer in fleet")
- Click Deactivate to confirm
What happens:
- The directive moves from Active to Deactivated view
- Associated maintenance actions are updated or terminated based on the directive's configuration
- The deactivation reason and date are recorded for audit purposes
4 Understanding the table
The Technical Directives table displays different columns depending on whether you're viewing Active or Deactivated directives.
Active Directives Table Columns
| Column | Description | Notes |
|---|---|---|
| Edit | Button to open the directive for editing | Only visible if you have edit permissions |
| Code | The directive reference number | Click to view full details in read-only mode; sortable |
| Type | Shows whether it's an AD or SB | ADs show a red badge; SBs show a blue badge |
| Category | For Service Bulletins: Alert / Mandatory, Recommended, Optional, or Informational | ADs don't have a category (always mandatory) |
| Title | Brief description of the directive | Truncated; hover to see full text; sortable |
| Notes | Additional information, references, or instructions | Truncated; hover to see full text |

Deactivated Directives Table
The Deactivated view shows all previously active directives that have been deactivated. It includes all the Active columns plus two additional ones:
- Reason for deactivation: The explanation provided when deactivating
- Deactivated (UTC): The date and time the directive was deactivated
The Edit button is replaced with a green Activate button that allows you to restore the directive if needed.
5 Maintenance intervals explained
Technical directives use maintenance intervals to define when compliance actions are due. Understanding how to set these correctly is essential for accurate tracking.
Initial Interval
The initial interval defines when the first compliance action must be completed. You can specify:
- Flight hours: Hours since last overhaul or total airframe hours
- Cycles: Takeoff-landing cycles
- Calendar time: Days, months, or years from effective date
- Combinations: Whichever comes first (e.g., 500 hours or 12 months)
Recurring Interval
The recurring interval defines how often the action repeats after initial compliance. Leave empty for one-time directives.
- Uses the same interval types as initial
- Typically shorter than initial intervals
- Creates ongoing maintenance actions
- Can be terminated by completing a terminating action
6 Applicability and scope
The Scope section determines which aircraft, engines, propellers, or parts in your fleet are affected by the directive.
6.1 Component types
Available Component Types
- Airframe: Applies to specific aircraft or all aircraft of a type

- Engine Part: Applies to a specific part type on engines
