Equipment & configuration
ATR 72 equipment list and configuration records review
This review reconciles an ATR 72's equipment list against the installation records, release certificates, and modification approvals that should support each installed item. A records specialist runs it before a transaction, after equipment turnover, or when the list has not been reconciled to source in some time. It checks that each listed item has an installation record and a release, that installed items appear on the list, and that the whole reconciles to a single configuration. You receive a reconciled equipment list, a list of items missing installation or release evidence, and the source references behind the current configuration.
When this review is needed
- The equipment list has not been reconciled against installation records since the aircraft changed operators.
- A period of equipment turnover left items on the aircraft that may not be on the list.
- A buyer needs the installed configuration confirmed item by item before acceptance.
- A release certificate for an installed unit cannot be located and the item's standing is in doubt.
The problem
The equipment list is meant to be the roster of what is installed, but it drifts as units come off for repair and go back on, as role equipment gets swapped, and as modifications add or remove items. A unit installed without its entry, or an entry left behind after removal, means the list and the aircraft disagree. On an ATR 72 that has cycled through regional roles, the role-specific equipment is exactly where the list most often fails to match what is fitted.
What gets reviewed
- Each listed item matched to its installation record and release certificate
- Installed items confirmed present on the equipment list
- Role and optional equipment reconciled to the modification approvals that authorize it
- Removed items confirmed cleared from the list rather than left as ghosts
- The equipment list reconciled to a single current configuration statement
- Part and serial numbers on the list checked against the release and installation records
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Send a representative, redacted record set and we will scope the review.
What gets validated
- Every item on the list carries an installation record and an acceptable release
- Each installed unit that requires listing actually appears on the equipment list
- Part and serial numbers reconcile across the list, the release, and the installation record
- Role or optional equipment traces to a modification approval where the type requires one
- Removed items are cleared from the list so it reflects the current aircraft only
Evidence normally required
- The current aircraft equipment list or configuration record
- Installation records for the listed and installed items
- Release certificates for installed units
- Modification approvals covering role or optional equipment
Common discrepancies
- An installed unit with no release certificate on file to support it
- A list entry for an item that was removed and never cleared from the record
- A part or serial number that does not reconcile between the list and the release
- Role equipment fitted without the modification approval the type requires
What is at stake
An equipment list that disagrees with the aircraft undermines the configuration baseline and every status built on it. An installed item without a release certificate is unsupportable at a transaction, and a listed item that is not actually fitted overstates the aircraft, so both directions of drift cost value or force a physical reconciliation late in a deal.

How the work runs
Take the roster
Assemble the current equipment list and the installation and release records for it.
Match both directions
Confirm listed items are installed and supported, and installed items are listed.
Reconcile the numbers
Check part and serial numbers agree across the list, the release, and the installation record.
Clear and flag
Remove ghost entries and list the items missing installation or release evidence.
What the buyer receives
- A reconciled equipment list tied to installation and release evidence
- A list of items missing installation or release support, in either direction of drift
- The source references establishing the current installed configuration
Who uses the output
- Records teams building a configuration baseline the file can rest on
- Asset and acquisition teams confirming the aircraft matches what the records claim
- CAMO leads relying on an accurate equipment roster for status tracking
How the work fits into the transaction or program
The equipment list is one input to the configuration baseline, alongside the modification and weight records. Reconciling it removes the ghost entries and unsupported installations that would otherwise distort the baseline, and any item missing a release routes to remediation before the configuration is relied on.
Aircraft-specific considerations
ATR 72 role and optional equipment, from cabin fit to freighter provisions, moves on and off the aircraft as it changes operators, so the equipment list drifts most in exactly the items that define the aircraft's current role. The review concentrates on that role-specific equipment, where a fitted item without a listing or a listed item without an installation is most likely to appear.
Jurisdiction-specific considerations
Release-document conventions differ between FAA and EASA systems, so an item released under one may need supplementary documentation to satisfy the other. The review notes where an installed unit's release will need supporting evidence for the receiving authority after a register change.
Regulatory limits
The review confirms the equipment list is internally consistent and supported by installation and release evidence. It does not certify any installed item, approve a configuration, or determine that the equipped aircraft is airworthy.
What this review does not cover
- A physical inspection or survey of the installed equipment
- Issuing a release certificate for any installed item
- Any airworthiness determination on the installed configuration
Specific to this review
- The equipment list drifts in two directions: ghost entries for removed items and unlisted items that are fitted.
- Role-specific equipment is where the ATR 72 list fails most, because that is what changes with the operator.
- An installed unit without a release is unsupportable at transaction even if the physical condition is sound.

Frequently asked questions
How is this different from a modification-status review?
The modification review reconciles the changes and STCs applied to the aircraft against their approval basis. This review reconciles the installed equipment roster against installation and release evidence. They overlap where role equipment is fitted under a modification, and they are usually run together to close both the change and the item behind it.
