777 family task cards
Boeing 777 family task-card evidence records review
This review checks that the closed task cards on a Boeing 777 family aircraft carry complete sign-offs and tie to the maintenance instructions they were raised against. It is run for a lessor, airline, or asset manager evaluating, transferring, or holding a specific tail. The work reads the closed task-card set against the work package, confirming stamps, inspection sign-offs, and the referenced instruction for each card. You receive a supported exception list, a source map linking cards to their instructions, and a closure plan for the serial number under review.
When this review is needed
- A 777 heavy check just closed and the task-card set has to be confirmed complete before the aircraft leaves the dock.
- A redelivery requires every mandated card in the work package to show a valid sign-off.
- A buyer wants the closed cards reconciled to the maintenance instructions they reference.
- An inspection card set is missing stamps and the closure has to be confirmed before the check is accepted.
The problem
A heavy check on a widebody produces thousands of task cards, and each one has to be signed, stamped where inspection is required, and tied to the instruction it was raised against. A card closed without a required inspection stamp, or one that references a superseded revision of an instruction, leaves a hole in the work package that a buyer or auditor will find. On a large card set those holes hide in volume until someone reconciles the whole package.
What gets reviewed
- The closed task-card set reconciled to the work package that raised it
- Sign-offs and mechanic stamps confirmed present on each card
- Inspection stamps confirmed where the card requires an independent inspection
- Each card tied to the maintenance instruction and revision it references
- Deferred and carried-forward cards tracked to their disposition
- Structural and inspection cards from the heavy check reconciled to the program
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 card in the work package shows a valid mechanic sign-off
- Cards requiring independent inspection carry the inspection stamp
- Each card references a current, not superseded, revision of its instruction
- Deferred cards are tracked to a disposition rather than left open
- The closed card set reconciles to the tasks the work package mandated
Evidence normally required
- The closed task-card set for the check or event
- The work package that raised the cards
- The referenced maintenance instructions and their revision status
- The list of inspection tasks requiring independent sign-off
- Deferral and carry-forward records for open cards
Common discrepancies
- A card closed without the inspection stamp its task required
- A card referencing a superseded revision of a maintenance instruction
- A deferred card with no disposition recorded in the package
- A mandated card missing from the closed set the work package called for
What is at stake
An incomplete task-card set can hold up acceptance of a check and delay a redelivery until the missing sign-offs are recovered or the work is re-accomplished. A card tied to a superseded instruction may mean the wrong procedure was flown, which is far more expensive to resolve than a missing stamp, and unresolved cards erode confidence in the entire work package.

How the work runs
Pull the package
Assemble the closed card set and the work package that raised it for the check or event.
Confirm the sign-offs
Check each card for a valid mechanic stamp and an inspection stamp where required.
Tie cards to instructions
Confirm each card references a current revision of the instruction it was raised against.
List the exceptions
Flag cards missing sign-offs, stamps, or references and sequence the completions.
What the buyer receives
- A supported exception list of cards missing sign-offs, stamps, or references
- A source map linking each card to its maintenance instruction and revision
- A closure plan sequencing which cards to complete before the next milestone
Who uses the output
- Records teams confirming a heavy-check package before the aircraft leaves the dock
- Continuing-airworthiness teams accepting a check on a complete card set
- Buyers confirming the redelivery work package holds up before closing
How the work fits into the transaction or program
The task-card set is the evidence that a check was actually accomplished, so this review runs at check exit or before a redelivery relies on the package. The exception list drives completion of the open cards while the shop and the mechanics who ran them are still on site, and the reconciled set becomes the work-package evidence a counterparty accepts.
Aircraft-specific considerations
A 777 heavy check carries a large structural and systems card content driven by its long-range program, and the ETOPS-significant systems tasks on the applicable variants require particular attention to independent inspection sign-off. The volume of cards means gaps concentrate in the non-routine and structural sections rather than the routine ones, so the reconciliation is scoped to this check's actual package rather than a generic card list.
Jurisdiction-specific considerations
Independent inspection and sign-off expectations differ between FAA and EASA practice, so a 777 work package accomplished under one system needs its inspection stamps checked against what the receiving register or operator will accept.
Regulatory limits
The review reconciles the task-card set to the work package and the instructions behind it. It does not sign off a task, accept a check, or determine that the maintenance or the aircraft is airworthy.
What this review does not cover
- Performing or re-performing any task on a card
- Signing off or stamping any task card
- Any airworthiness or check-acceptance decision on the aircraft
Specific to this review
- On a 777 heavy check the missing sign-offs cluster in the non-routine and structural card sections, not the routine ones, because those cards are raised and closed under time pressure.
- A card referencing a superseded instruction revision is worse than a missing stamp, because it may mean the wrong procedure was accomplished.
- The sheer card count on a widebody check means reconciliation to the work package, not card-by-card reading alone, is what surfaces the gaps.

Frequently asked questions
Does a missing inspection stamp mean the work was not done?
Not necessarily, but it means the record cannot prove the required independent inspection took place. The card is flagged so the stamp can be recovered or the inspection re-accomplished, because an unstamped inspection card can hold up acceptance of the check.
