LEAP equipment list
Equipment-list records review for LEAP engine assets
This review confirms that the equipment list and configuration records for a LEAP-powered aircraft match what is installed and that each item traces to its installation and release evidence. It is run for a lessor, airline, or manager evaluating, transferring, or maintaining the asset, usually where equipment has been added or swapped across operators. It works through the equipment lists, installation records, release certificates, and modification approvals, tying each listed item to its supporting document. You receive a supported exception list, a source map per item, and a closure plan for this asset.
When this review is needed
- Equipment has been added or swapped on a LEAP-powered aircraft and the list has to reconcile to the installations.
- A buyer wants each listed item supported by installation and release evidence before pricing the asset.
- An item on the list is claimed installed but its release certificate or approval is not on file.
- A swap was treated as routine when the equipment change should have carried a modification approval.
The problem
The equipment list is meant to state exactly what is fitted, but items get added, swapped, and removed faster than the list is maintained. On a LEAP-powered aircraft, each installed item should trace to an installation record, a release certificate for the unit, and a modification approval where the change required one. When a listed item has no release evidence, or a swap happened without updating the list, the record stops describing the build a buyer or an operator relies on.
What gets reviewed
- Each listed item reconciled to its installation record
- Release certificates confirmed present for installed units
- Modification approvals tied to equipment changes that required them
- The equipment list checked against the current installed configuration
- Removed items confirmed off the list and their removal recorded
- Swaps recorded as modifications where the change required approval

What gets validated
- Every listed item traces to an installation record for the aircraft
- Installed units carry a release certificate an auditor or buyer would accept
- Equipment changes that required a modification approval carry one
- The list reflects the current installed configuration with no stale entries
- Removed items are off the list and their removal is recorded
Evidence normally required
- The aircraft equipment list and configuration records
- Installation records for listed equipment
- Release certificates for installed units
- Modification approvals covering equipment changes
- Removal records for items taken off the aircraft
Common discrepancies
- A listed item with no release certificate on file for the installed unit
- An equipment swap that was never reflected on the list
- A change that needed a modification approval but was recorded as routine
- A removed item still carried on the list with no removal record
What is at stake
An equipment list that does not match the installed build undermines the configuration status and the weight-and-balance record built alongside it. A listed item with no release evidence cannot be relied on for resale or continued use, and a change treated as routine when it needed a modification approval leaves the configuration unsupported until the basis is reconstructed.

How the work runs
Reconcile list to installs
Tie each listed item to its installation record for the aircraft.
Confirm release and approval
Check that installed units carry release certificates and required modification approvals.
Check against the build
Compare the list to the current installed configuration and clear stale entries.
List the exceptions
Flag items without evidence and the documents needed to close them.
What the buyer receives
- A supported exception list of items that do not reconcile to installation or release evidence
- A source map linking each listed item to its installation and release records
- A closure plan for recovering the evidence each open item needs
Who uses the output
- Asset managers pricing the configuration the equipment records actually support
- Records teams recovering release certificates for installed units
- Continuing-airworthiness teams relying on the list to match the installed build
How the work fits into the transaction or program
The equipment-list review sits beside the modification-status and weight-and-balance records, because an equipment change should be visible in all three. It runs before the configuration record feeds a transaction, so the list a counterparty reads matches the installed, released build rather than a stale snapshot.
Aircraft-specific considerations
On a LEAP-powered aircraft the equipment list is usually maintained in a digital configuration system, so the review confirms that each listed item's release certificate was linked into the record rather than filed separately. Because the fleet is newer, the equipment changes tend to be recent avionics or cabin updates, and the review checks that a swap logged in the system carried its release evidence with it.
Regulatory limits
The review confirms the equipment list reconciles to installation and release evidence. It does not install or remove equipment, issue a release certificate, approve a modification, or make an airworthiness determination on the installed configuration.
What this review does not cover
- Installing, removing, or inspecting any equipment
- Issuing a release certificate or approving a modification
- Any airworthiness determination on the installed configuration
Specific to this review
- On a LEAP-powered aircraft the equipment list most often breaks at a swap that updated the system entry but never linked the new unit's release certificate.
- A stale entry for a removed item is as damaging as a missing one, because it claims a build the aircraft no longer has.
- A cabin or avionics change treated as routine, when it needed a modification approval, is the item most likely to leave the list unsupported at a transaction.

Frequently asked questions
The equipment list looks current. Why check each item's release certificate?
A current-looking list can still carry items whose release evidence was never filed, and a unit without an acceptable release certificate cannot be relied on for resale or continued use. The review ties each listed item to its release and installation records, which is what a buyer verifies before trusting the configuration.
