Equipment list & configuration
Pilatus PC-12 equipment list and configuration records review
This review confirms that the aircraft equipment list for a Pilatus PC-12 matches what the installation and release records show is actually fitted. It suits a buyer, lessor, or manager who needs the configuration inventory to hold before a transaction or a mission change. The work reconciles each listed item to its installation record, release certificate, and modification approval for the single-engine turboprop. You receive an exception list of items that appear on the list without support or are installed without appearing, a source map to the paperwork behind each entry, and a closure plan for the tail.
When this review is needed
- A PC-12 equipment list has not been rebuilt after several avionics or interior changes.
- A buyer wants installed equipment reconciled to approval data before closing.
- A role change means items will be added or removed and the baseline list must be trustworthy first.
- The list shows items whose installation paperwork nobody has located.
The problem
The PC-12 equipment list is meant to be the running inventory of what is fitted, but on an owner-managed aircraft it drifts as items are added or pulled without the list being updated in step. A radio replaced at one shop, a camera pod fitted for a season and later removed, an interior swapped for cargo work: each event should move the list and carry a release certificate, yet the list and the paperwork diverge quietly. By the time a buyer reads it, the list can name equipment that is gone and omit equipment that is present.
What gets reviewed
- Each listed item reconciled to an installation record and a release certificate
- Installed items confirmed present on the list rather than omitted
- Modification approvals tied to items that required an STC or field approval to fit
- Removed equipment cleared from the active list with a removal record
- The list configuration checked against the recorded modification status
- Part and serial numbers on the list matched to the release paperwork on file
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 traces to an installation record and an authorized release certificate
- Items physically installed per the work packages all appear on the current list
- Equipment requiring an STC or field approval carries that basis rather than a routine sign-off
- Removed items are struck from the active list and supported by a removal entry
- Part and serial numbers on the list match those on the release paperwork
Evidence normally required
- The current aircraft equipment list and its revision history
- Installation records and work packages for avionics and mission equipment
- Release certificates for the listed and recently changed items
- Modification and STC records tied to installed equipment
- Removal records for equipment taken off the aircraft
Common discrepancies
- A listed item with no release certificate to support it
- Installed equipment absent from the current list
- An item removed from the aircraft but still shown as active
- A part or serial number on the list that disagrees with the release paperwork
What is at stake
An equipment list that does not match the aircraft undermines the weight and balance amendments and the modification status that both draw from it. A listed item with no release certificate cannot be relied on for resale, and an installed item missing from the list can surface a field approval nobody accounted for, stalling a transaction until the basis is found.

How the work runs
Baseline the current list
Take the active equipment list and its revision history as the starting inventory.
Match items to paperwork
Tie each entry to an installation record and release certificate, and confirm serial numbers agree.
Test for omissions
Check installed items from the work packages against the list to catch anything missing or stale.
Set closure actions
List unsupported, missing, and removed items and name the record that reconciles each.
What the buyer receives
- An exception list of unsupported, missing, or stale equipment entries
- A source map linking each list line to its installation and release evidence
- A closure plan naming the record needed to reconcile each disputed item
Who uses the output
- Asset managers confirming the configuration inventory the sale relies on
- Records teams rebuilding an equipment list that matches the paperwork
- Buyers checking that installed items carry a defensible approval basis
How the work fits into the transaction or program
The equipment list is the inventory that weight and balance amendments and modification status both reference, so settling it steadies two other parts of the PC-12 file at once. Running the reconciliation before a role change means new additions and removals start from a list that already matches the aircraft.
Aircraft-specific considerations
PC-12 operators swap equipment to suit passenger, medevac, surveillance, and cargo roles, so the equipment list turns over more than on a fixed-role aircraft and each swap should carry its own release paperwork. Because those changes happen at whichever shop is convenient to an owner-manager, the list and the release certificates most often diverge at role transitions, which is where the review concentrates for this serial number.
Jurisdiction-specific considerations
The form and detail of an equipment list accepted under FAA practice can differ from what an EASA-registered aircraft is expected to carry, so a PC-12 changing register may need the list re-cast and its supporting releases re-mapped to the receiving system's expectations.
Regulatory limits
The review confirms the equipment list is consistent with the installation and release records. It does not approve an installation, issue a release certificate, or determine that any installed item is airworthy.
What this review does not cover
- A physical inventory or survey of installed equipment
- Issuing installation approvals or release certificates
- Any airworthiness determination on the listed items
Specific to this review
- The PC-12 equipment list drifts most at role transitions, when items go on and come off faster than the list is revised.
- An item present in the aircraft but missing from the list often points to a field approval that was never carried into the configuration record.
- Because weight and balance draws from the list, a stale equipment entry can quietly corrupt the loading data too.

Frequently asked questions
Why review the equipment list separately from modification status?
Modification status tells you which approved changes were embodied; the equipment list tells you which items are actually fitted and traceable. They reference each other, but an item can sit correctly on one and be wrong on the other, so the list is reconciled to its own installation and release paperwork.
