The Operations module must be enabled for your workspace. You also need the appropriate operations
permissions. Contact your workspace administrator if you cannot access these features.
You need the
maintenance_ops.read permission to view discrepancies and maintenance_ops.update
to create, defer, or resolve them.Prerequisites
- Aircraft must be registered in the fleet under Ops > Aircraft before a discrepancy can be filed against a tail number.
- Your operation’s MEL (derived from the manufacturer’s MMEL) should be on file so that MEL references are meaningful when deferring items.
Navigate to Discrepancies
Open the Operations sidebar and click Discrepancies under the Fleet group. Breadcrumb path: Ops > Discrepancies The page loads with a stat-badged tab row and a searchable table of all discrepancies in your workspace.Understand the status tabs
The four tabs across the top of the page filter the table and show a running count for each category:
Click any tab to filter the table to that status. The count badge on each tab updates
live as you add or resolve items.
Read the discrepancy table
Each row in the table represents a single write-up:
Use the search field above the table to filter by description text or aircraft
registration. The search is case-insensitive and updates as you type.
Open the discrepancy detail page
Click any row in the discrepancy table to open the discrepancy detail page (Ops > Discrepancies > [ID]). The detail page shows:
- Full write-up text, severity, and reporting information
- Current status with the full status history
- MEL reference and deferral justification (if deferred)
- Corrective action and resolution details (if resolved)
- Direct action buttons: Resolve, Defer, and Reopen
File a new discrepancy
Grounding-severity discrepancies automatically surface on the Fleet Health dashboard’s Discrepancy
Summary donut in dark red. The Fleet Health Open Squawks KPI increments for every Open and
Deferred discrepancy across the fleet.
Defer a discrepancy under the MEL
Deferral is the process of formally documenting that a non-critical fault will remain unrepaired for a defined period while the aircraft continues in service — allowable under 14 CFR 135.179 when the item appears in your approved MEL.Resolve a discrepancy
Resolution records the corrective action taken and closes the write-up.How discrepancies affect aircraft dispatch
Open discrepancy severity determines whether an aircraft can be dispatched:
The Open Squawks column on the Aircraft list page shows each aircraft’s open
discrepancy count. A count greater than zero is highlighted in red as a visual
dispatch flag. Dispatchers and pilots should review open squawks as part of the
standard pre-flight release process per 14 CFR Part 135 Subpart J.
Fleet Health integration
The Fleet Health dashboard (Ops > Fleet Health) aggregates discrepancy data into
three summary views:
- Open Squawks KPI card — Total count of Open, Deferred, and In Progress discrepancies across the entire fleet. The card turns red when the count is greater than zero.
- Discrepancy Summary donut — Breaks open squawks down by severity (Minor, Major, Critical, Grounding). Use this to identify whether open items are routine or require immediate maintenance intervention.
- Open Discrepancies table — Lists the 20 oldest unresolved discrepancies sorted by report date. Click any row to navigate directly to the Discrepancies page.
Ops > Aircraft > [tail number]).
