Boeing 767 configuration
Boeing 767 family equipment-list and configuration records review
This review confirms that the equipment list and configuration records for a specific Boeing 767 serial number describe what is actually installed on the airframe. It is run for a buyer, lessor, or records team preparing the asset for a sale, lease, or program change, before anyone relies on the configuration as delivered. It checks the master equipment list, installed-part effectivity, STC and modification approvals, and the installation paperwork that ties each change to accepted data. You receive an exception list keyed to the serial number, a source map behind every entry, and a plan to close the items that do not reconcile.
When this review is needed
- A 767 is going to market and the buyer expects the configuration statement to match the installed hardware.
- The airframe passed through a freighter conversion and the cargo-system installation needs to appear correctly in the equipment list.
- An operator is bringing the aircraft onto a new program and the entry configuration has to be fixed against approved data.
- A cabin or avionics retrofit closed without the equipment list being updated to reflect the embodied change.
The problem
On a 767 that has flown for two or three decades, the equipment list rarely keeps pace with what shops actually did to the airframe. Retrofits get embodied, parts get swapped under an STC, and interiors get reconfigured, but the configuration statement drifts behind. By the time the records team looks, they cannot say with confidence whether a listed line item is still installed or whether an installed item was ever captured on paper.
What gets reviewed
- Master and current equipment list reconciled against the installed part numbers for this serial
- STC and minor-modification approvals matched to the changes they authorize
- Installation records tying each embodied change to accepted or approved data
- Effectivity of each modification confirmed against the airframe block and line number
- Interior, avionics, and cargo-system configuration captured for the current standard
- Prior configuration entries reconciled where a later change superseded them

What gets validated
- Each installed part number in the equipment list traces to an installation record and a release document
- Every STC referenced carries its approval and an ICA where the modification requires one
- Modification effectivity matches this serial number rather than a family-wide applicability note
- Freighter-conversion or major-retrofit hardware appears in the configuration statement with its approval basis
- Removed items no longer carried as installed have a removal record that closes the entry
Evidence normally required
- The current master equipment list and any configuration baseline the operator maintains
- STC certificates, modification approvals, and the associated installation paperwork
- Release documents for installed components carrying a serial or batch reference
- Freighter-conversion or heavy-retrofit records if the airframe has been converted
- Effectivity and line-number data identifying this specific 767 serial
Common discrepancies
- Installed retrofit hardware that never made it into the equipment list after embodiment
- STC references on the aircraft with no approval or ICA in the records
- Equipment-list entries for parts that were removed years earlier and never cleared
- Modification effectivity claimed against the family that does not apply to this line number
What is at stake
A configuration statement that does not match the aircraft turns every downstream task into rework. The receiving operator questions the entry status, the buyer discounts for the uncertainty, and an installation that lacks its approval basis can force a part removal that nobody budgeted. Left unresolved, the drift compounds with each further modification.

How the work runs
Fix the reference configuration
Establish the current standard for this serial from the equipment list and the modification history.
Reconcile installed against listed
Match installed part numbers and embodied modifications to the equipment-list entries and their approvals.
Trace each change to its basis
Confirm every modification carries approval data and an ICA where required, keyed to this line number.
Report exceptions and closure
Deliver the keyed exception list, source map, and a plan to close the mismatches.
What the buyer receives
- A configuration exception list keyed to the serial number with each mismatch identified
- A source map linking every reconciled entry to its installation and approval evidence
- A closure plan sequencing the open items by how they block a trade or program entry
Who uses the output
- Asset managers pricing a 767 against a verified rather than a nominal configuration
- Records teams setting the entry configuration for a new maintenance program
- Technical buyers confirming that installed hardware carries an approval basis
How the work fits into the transaction or program
Configuration is the reference frame the rest of the records hang from. Once the equipment list is reconciled to the airframe, the AD position, repair map, and release evidence can be checked against a configuration that is known to be true rather than assumed. This review is usually run early in a diligence or program-entry pass so the later checks are not built on a drifting baseline.
Aircraft-specific considerations
A 767 airframe carries decades of configuration change: freighter conversions that add main-deck cargo systems, cabin reconfigurations across several operators, and avionics retrofits driven by airspace mandates. Older serials often trace part of their configuration through paper amendments that predate any digital equipment list, so the review scopes to this serial's actual conversion and retrofit history rather than a generic 767 template.
Jurisdiction-specific considerations
Where the airframe has operated under both FAA and EASA oversight, a modification may sit on an STC recognized in one jurisdiction and a validated approval in the other. The review notes which approval basis supports each change so the receiving authority's records team can see the path without re-deriving it.
Regulatory limits
This review reports what the configuration evidence supports and where it falls short. It does not issue an airworthiness determination, approve or validate any modification, and does not substitute for the operator's acceptance of the aircraft onto its program.
What this review does not cover
- Physical inspection or survey of the installed configuration
- Preparation or approval of new modification or STC data
- Entry of the aircraft onto the receiving operator's maintenance program
Specific to this review
- A freighter-converted 767 adds a large block of configuration that must trace to the conversion STC, not just to the base type design.
- Equipment-list drift is worst around avionics mandates, where several retrofits stack over a short period and older entries are rarely retired.
- A part shown as installed but removed years earlier is as much a defect as a missing entry, because it corrupts the configuration the next team relies on.
- Effectivity noted at the family level often masks whether a specific line number was ever eligible for the modification claimed.

Frequently asked questions
Why review the equipment list separately from a full records audit?
The configuration is the baseline everything else references. Reconciling it first means the AD, repair, and release checks are measured against a configuration that is known to match the airframe, which keeps those later findings from being contaminated by a drifting equipment list.
What happens to an installed modification with no approval in the records?
It is logged as an exception with the specific missing evidence identified. The closure plan then sequences whether the approval can be retrieved, whether an acceptable basis exists, or whether the item has to be escalated before a trade or program entry proceeds.
