Equipment and configuration
Bombardier CRJ family equipment-list records review
This review confirms that a CRJ's equipment list reflects what is installed and that each listed item carries the installation record and release certificate its presence implies. It fits a team evaluating, transferring, or maintaining one tail, and it works from that aircraft's equipment list rather than a family baseline. The work reconciles listed equipment to installation records, checks that release certificates support each installed unit, and confirms modification approvals cover the items that required them. You receive an exception list of items without supporting records, a source map from the list to the paperwork, and a closure plan for that airframe.
When this review is needed
- A CRJ is being transferred and each installed item on the equipment list has to be backed by records.
- Avionics or cabin equipment was changed and the list has not been reconciled to the installations.
- A release certificate is being relied on for an installed unit and its match to the installation is unchecked.
- A modification review found installed equipment whose listing and approval have to be confirmed.
The problem
A CRJ's equipment list should be a live inventory of what is fitted, but on a tail that has been refitted across operators the list and the airframe drift apart. An avionics unit can be installed without reaching the list, a listed item can carry no installation record, and a release certificate can be on file for a part number that does not match what is fitted. The list reads as configuration control while the actual configuration has moved on.
What gets reviewed
- Listed equipment reconciled to the installation records that put each item on the aircraft
- Release certificates checked for a match to the part and serial number installed
- Modification approvals confirmed for equipment changes that required them
- Items installed but absent from the list identified and reconciled
- Listed items with no installation record flagged as exceptions
- Interchangeability and effectivity confirmed where a fitted part differs from the baseline

What gets validated
- Each listed item has an installation record placing it on this aircraft
- A release certificate on file matches the part number and serial number installed
- Equipment changes that required a modification approval carry one
- Installed equipment not on the list is captured and reconciled
- Part effectivity and interchangeability support the item fitted to this serial number
Evidence normally required
- The current aircraft equipment list
- Installation records for the listed and installed equipment
- Release certificates for the installed units
- Modification approvals for equipment changes
- The configuration and effectivity reference for the aircraft
Common discrepancies
- An installed unit whose release certificate cites a different part number
- A listed item with no installation record on file
- Equipment fitted to the aircraft that never reached the equipment list
- An equipment change that required a modification approval and has none
What is at stake
An equipment list that does not match the aircraft undermines the modification baseline and puts the release evidence behind every installed unit in doubt. At a transfer, an installed unit without a matching release certificate is a value and airworthiness question the buyer will not carry, and a listed item with no installation record has to be resolved before the configuration can be relied on.

How the work runs
Reconcile the list to installs
Match each listed item to the installation record that placed it on the aircraft.
Verify release evidence
Confirm a release certificate on file matches each installed part and serial number.
Reconcile installs to the list
Identify installed equipment missing from the list and capture it.
List the exceptions
Flag items without supporting records and order them by configuration and transfer impact.
What the buyer receives
- An exception list of equipment items without supporting records
- A source map from each list line to its installation and release evidence
- A closure plan ordered by which items block configuration or transfer
Who uses the output
- Records teams reconciling the equipment list before a transfer or an audit
- CAMO leads confirming release evidence behind each installed unit
- Asset managers relying on an equipment list that matches the airframe
How the work fits into the transaction or program
The equipment-list review completes the configuration picture the modification review starts, moving from approved changes to the individual units fitted and the release evidence behind them. Its exception list feeds the release-document and structural reviews and supports the configuration a data room presents at a transfer.
Aircraft-specific considerations
CRJ operators change avionics and cabin equipment frequently over the family's service life, so the equipment list is a live document that drifts fastest at operator changes when refit work and records work are handled separately. Regional aircraft carry roll-on equipment and cabin fits that vary by operator, which makes the reconciliation between the list and the installed units the place where the configuration most often diverges.
Jurisdiction-specific considerations
FAA and EASA differ on the release document each recognizes for an installed part, so a CRJ moving between systems is checked for whether the release evidence on file will be accepted by the receiving authority, and units whose paperwork would need re-release are flagged rather than assumed acceptable.
Regulatory limits
The review reconciles the equipment list to the records behind it and lists what is unsupported. It does not release a part, approve an installation, or determine that the aircraft is in an airworthy configuration.
What this review does not cover
- Issuing a release certificate for any installed unit
- A physical inventory or configuration survey of the aircraft
- Any airworthiness determination on the installed configuration
Specific to this review
- An equipment list is only reliable if it is reconciled both ways: listed items need records, and installed items need to be on the list.
- A release certificate that cites a part number different from the one fitted is a real trace break, not a clerical detail, because the paperwork no longer proves the installed unit.
- Roll-on and cabin equipment vary by CRJ operator, so a fitted unit that never reached the list is a routine finding on a tail that changed hands.

Frequently asked questions
Do you physically inventory the aircraft to build the list?
No. The review works from the records, reconciling the equipment list against installation and release documents both ways. A physical configuration survey is a separate exercise that is often run alongside it when the records raise questions the paperwork alone cannot settle.
