Falcon 7X deferrals
Dassault Falcon 7X deferred-maintenance records review
This review reconciles the deferred-maintenance record for a Dassault Falcon 7X, confirming that each open deferral rests on a valid MEL or CDL basis and that cleared items were actually closed. It is run for owners, lessors, and managers who need to know what is genuinely open on the tail and whether each deferral is within its limit. The work checks each deferment against its category and time limit and matches clearing entries to the corrective work behind them. You receive a reconciled deferral log, an exception list of expired or unsupported deferments, and the clearing evidence per item.
When this review is needed
- A Falcon 7X is heading into a transfer and the true set of open deferrals has to be established.
- A deferral has been carried for a while and its category time limit may have expired.
- A cleared item shows on the log but no corrective work is recorded against it.
- The deferral log and the technical log disagree about what is actually open on the tail.
The problem
Deferred maintenance is where small items pile up quietly: a deferral is raised against an MEL category, carried past its time limit, or cleared on the log without the corrective work behind it. On a Falcon 7X the deferral record and the technical log can drift apart, so the true count of open items is not what either says alone. An expired or unsupported deferral looks like a routine carry-forward until someone reconciles the log to the corrective evidence.
What gets reviewed
- Each open deferral matched to its MEL or CDL reference and category
- Deferral time limits checked against the category and the date raised
- Clearing entries matched to the corrective work recorded against them
- The deferral log reconciled to the technical log for a true open-item count
- Repeated deferrals of the same item identified as a recurring condition
- Deferrals carried across a check confirmed as still valid afterward
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
- Each open deferral cites a valid MEL or CDL reference and the correct category
- No deferral is carried beyond the time limit its category allows
- Every cleared item shows a corrective entry that resolves the deferred defect
- The deferral log and the technical log agree on what is open on the tail
- Repeatedly deferred items are flagged as a recurring condition rather than routine
Evidence normally required
- The deferred-maintenance log for the tail
- The MEL and CDL applicable to the Falcon 7X operation
- The technical log for cross-reference on open items
- Corrective-action records for cleared deferrals
- Check packages where deferrals were raised or cleared
Common discrepancies
- A deferral carried past the time limit its MEL category allows
- A cleared item on the log with no corrective entry behind it
- A deferral log and technical log that disagree on the open-item count
- The same defect deferred repeatedly, pointing to a recurring condition
What is at stake
A deferral carried past its category time limit is an open exposure, and a cleared item with no corrective entry may still be unresolved on the aircraft. Carried into a transfer, an uncontrolled deferral list becomes the receiving side's problem, inflates the open-item count in diligence, and can hold up acceptance until each deferral is either closed or properly carried.

How the work runs
Assemble the open set
Pull the deferral log and reconcile it against the technical log to find the true open items.
Test each deferral
Confirm the MEL or CDL basis, category, and time limit for every open deferment.
Verify the clears
Match each cleared item to the corrective work that resolved the deferred defect.
Flag the exceptions
List expired, unsupported, or recurring deferments and the evidence needed to close each.
What the buyer receives
- A reconciled deferral log showing the true set of open items on the tail
- An exception list of expired, unsupported, or recurring deferments with what each needs
- The clearing evidence assembled for the items marked closed
Who uses the output
- Records teams establishing the true open-item count before the file is relied on
- Continuing-airworthiness staff confirming no deferral has run past its limit
- Buyers and redelivery teams making sure no uncontrolled deferral transfers unnoticed
How the work fits into the transaction or program
Deferred maintenance is the running edge of the file, the set of items known but not yet closed, so it has to reconcile with the technical log and the non-routine record. Establishing the true open list means the deferral count in a transaction is accurate and the receiving operator inherits a controlled set rather than a surprise.
Aircraft-specific considerations
The Falcon 7X operates under an MEL that reflects its trijet configuration and heavily integrated avionics, so deferrals frequently touch redundant systems where the dispatch condition depends on which units remain serviceable, and the review pays attention to whether a deferral against one channel of a redundant system was raised and time-limited correctly for this type.
Jurisdiction-specific considerations
The MEL basis and the deferral categories can differ between an FAA and an EASA operation, so a deferral valid under one operator's MEL may not carry to another, and the review notes where open items will need reassessment against the receiving operator's MEL.
Regulatory limits
The review reports whether deferrals are within limit, supported, and cleared with evidence. It does not authorize a deferral, approve an MEL, or determine that the aircraft is airworthy for dispatch.
What this review does not cover
- Authorizing a deferral or approving an MEL or CDL
- Performing or inspecting the corrective work behind a deferral
- Any dispatch or airworthiness determination on the aircraft
Specific to this review
- The deferral log and the technical log routinely disagree, so the true open count comes from reconciling the two rather than trusting either.
- A deferral carried past its category time limit is a live exposure that reads like a routine carry-forward until it is checked against the raised date.
- A defect deferred repeatedly is a recurring condition in disguise, which the review surfaces rather than counting as a series of routine deferrals.

Frequently asked questions
Why reconcile the deferral log against the technical log?
The two records drift apart in practice: an item can be closed in one and left open in the other, or raised in one without appearing in the other. The true set of open deferrals only emerges when both are reconciled, and that reconciled count is what a transaction actually needs.
