What is Rotable Repair Management?

Rotable Repair Management tracks each rotable from removal through repair and warranty back to stock, for component teams. Eight AI agents put every serialized unit on one repair loop, check warranty against the shop's clause and the release certificate before any quote is approved, set quotes against past repairs, chase late shops from their own contracts, protect the shelf and draft warranty claims. The component repair manager approves, edits or rejects every claim, quote and routing.

The problem

Why rotable repair management leaks money today

Rotable repair management, also called component repair management, is the work of getting every serialized, repairable part — a generator, a pump, a flight computer, a wheel — from the aircraft to an outside repair shop and back to the shelf. A carrier of about 300 aircraft has around 1,300 units in that loop on any day, each tracked across the maintenance & engineering system, spreadsheets, shop portals and email. Every day of repair turnaround has to be covered with float stock.

The money leaks at the quote. The planner approves it in hours because the unit's absence is costing float, and checking warranty means finding the last repair order, its FAA Form 8130-3, the shop's warranty clause and the flight hours since installation — by hand. So in-warranty repairs get paid twice, quotes are not set against past repairs of the same finding, late shops are found when the shelf runs dry, a unit removed three times in nine months is shipped to the shop a third time, and a shop's denial of a claim is accepted because nobody has time to assemble the rebuttal.

Rotable repair management, one generator at a time: IDG S/N 7731 at ORD

Rotable repair management at Corvane Airways, told through one integrated drive generator. On Thursday, October 15, 2026, Meridian Electric Power Services has quoted $48,200 to repair IDG S/N 7731 — a unit Meridian itself repaired eleven months ago. Here is what happens next, screen by screen, in the working solution.

  1. 01Thursday morning

    Every rotable on one loop, and six decisions that need him

    Marcus Reyes · Component Repair Manager

    Marcus opens the repair loop: one circle of six stages with 1,284 units on it — 96 removed, 212 shipping, 341 at shop, 38 in warranty check, 486 in repair, 111 back to stock. Average turnaround is 47 days against a 35-day target, 63 units are late at the shop and $3.86M of warranty has been recovered this year. The selected dot is IDG S/N 7731, with the agents' note beside it, and under it, Needs you: 6.

    “Proposes: Reject the quote and send warranty claim WC-2610-031 for $48,200.”

  2. 02One click

    The unit's conversation with the agents, beside its evidence

    Marcus Reyes · Component Repair Manager

    Open the unit and the agents' work reads as a conversation, each line with its source. The Removal reader captured the removal on Oct 9 from tech log TL-ORD-55218 and opened repair order RO-2026-20417. The Quote analyst set Meridian's $48,200 against twelve past repairs with the same bearing finding: median $31,400, $24,900 to $39,800. The rotor assembly ($14,600) was replaced in only 1 of 12. If the warranty were refused, it would counter at $32,000.

    Quote against history: “+54% over median.”

  3. 03Before the quote

    The shop's own clause, found and counted

    Warranty checker

    The Warranty checker found Meridian's repair agreement §9.2 and the last repair, RO-2025-11842, released on Form 8130-3 MEP-25-11842 and shipped Nov 18, 2025. The unit has flown 1,900 of 4,000 flight hours in 11 of 18 months, and the teardown blames the bearing fitted at that repair. Every citation opens the passage the agents read.

    §9.2: “Repaired units are warranted against defects in material and workmanship for 4,000 flight hours or 18 months from the date of shipment, whichever occurs first.”

  4. 04Checked twice

    A second agent re-derives it without seeing the first working

    Verifier

    The Verifier works from the maintenance records and the release certificate alone, and agrees: 1,900 of 4,000 hours, 11 of 18 months. Marcus asks for the checks again and watches each step run in under a second — tech log, last repair, clause, independent re-check, quote history, shelf, claim — then the hand-off to him.

    “Same result as this morning. 6 sources read · 97% sure · handed to the Component Repair Manager.”

  5. 058:31 am

    The warranty claim, drafted with every statement cited

    Claim drafter

    Claim WC-2610-031 for $48,200 is written to Meridian's warranty desk: the last repair, the installation on N812CV, the removal for low oil pressure after 1,900 flight hours and 11 months, the failed bearing and §9.2. It rejects quote QT-MEP-55021 and asks for the repair at no charge within the 21-day turnaround of Schedule B. The evidence pack holds four documents, and the Verifier's five checks all agree.

    The Claim drafter asks one question first: §9.4 also makes Meridian pay the freight both ways on an accepted claim, $640 — add it to the claim?

  6. 068:43 am

    He asks, instructs, then decides

    Marcus Reyes · Component Repair Manager

    Marcus asks what happens to stock at ORD. The Pool planner answers: 2 serviceable IDGs against a minimum of 3, and S/N 6624, repaired at Meridian, is on the ORD shelf Friday, Oct 16 with a $3,200 overnight expedite — no aircraft waits. He types “Ask Meridian for 21 days” and the Shop follower adds the 21-day turnaround and its 1% a day late credit to the claim. He rejects the quote with the reason code “Covered by repair warranty”, ticks the statement and approves the claim.

    “Decided. Quote rejected and claim sent. Everything is in the audit trail.”

  7. 07On the record

    Who did what, when, and on what evidence

    Every agent and every person

    The audit trail shows the morning entry by entry: the Warranty checker's finding at 8:20 am, the Verifier's agreement at 8:24, the quote comparison, the claim draft, the Pool planner's expedite proposal, Marcus's rejection at 8:48 and his approval at 8:51, and the claim sent to Meridian's warranty desk with four documents and a 30-day reply clock. It exports as CSV and as an evidence pack.

    “Append-only · each entry signed.”

  8. 08The rest of the queue

    Quotes read from the teardown, line by line

    Quote analyst

    Aldergrove Hydraulics quoted $18,950 for engine-driven hydraulic pump S/N 2286 against a median of $12,400 over 14 repairs. The quote replaces the pump housing; the teardown says the housing is within limits, and it was replaced in only 2 of 14. Warranty was checked first — outside Aldergrove's 3,000 flight hours or 12 months, and the Verifier agrees. Proposed: counter at $12,900.

    “No quote reaches “approve” until the warranty check has run.”

  9. 0919 days late

    A late shop chased from its own contract

    Shop follower

    Air cycle machine S/N 5012 has been at Cobalt Pneumatics 44 days against a 25-day turnaround, and reminders of Oct 5 and Oct 12 were not answered. §7.3 of the repair agreement allows escalation to the account director after 10 days late and two unanswered notices, so the Shop follower drafts the letter: a ship date within two business days, late delivery credits under Schedule B from day 26. It waits for a person to approve and send.

    Routine first reminders go under a standing approval; escalations always need a person.

  10. 10SFO, empty shelf

    Late units tied to the shelf they empty, with the fix priced

    Pool planner

    SFO holds no serviceable auxiliary power unit against a minimum of 1, because S/N 0418 is 7 days late at Harbor APU Services. The Pool planner prices three ways out: an exchange APU from the pool at SFO on Oct 17 for $96,000, moving the ORD spare for $4,800 and leaving ORD at 0 of 1 for 9 days, or waiting for the promised Oct 19. Above $75,000 the exchange needs the Director of Materials to co-sign.

    “Agents never book an exchange or change a minimum.”

8 agents. Each with one job, and hard limits.

Eight specialist agents capture each removal, check warranty before every quote, chase late shops and draft the claim; the component manager decides.

Removal reader

Captures every removal from the tech log and the maintenance system, records the reason as written and the hours and cycles since installation, opens the repair order to the shop in scope and spots repeat removals.

  • Never closes or cancels a removal
  • Asks the station when the reason is unclear
Warranty checker

Before any quote is approved, finds the last repair, its Form 8130-3 or EASA Form 1 and the shop's warranty clause, and counts flight hours, cycles and months since shipment.

  • Cites the clause and the hours for every finding
  • Proposes only; never rejects a quote
Verifier

Re-derives each warranty and quote finding from the source records alone, then agrees or disagrees.

  • Never sees the first agent's working
  • Cannot create a finding; a disagreement shows both workings to the person deciding
Quote analyst

Reads the teardown and the quote and sets each line against past repairs of the same part with the same finding, and against contract caps, then drafts the counter or the rejection with its reason.

  • Never approves or counters on its own
Shop follower

Watches days at each shop against the contract turnaround, drafts follow-ups and escalations from the contract's own clauses, reads the shop's replies and updates promised dates.

  • Sends first reminders only under a standing approval a person set
  • Escalations need a person
Claim drafter

Drafts component warranty claims and rebuttals with the clause cited and the evidence pack attached — the repair agreement, the release certificate, the tech log and the teardown.

  • Never sends a claim
Pool planner

Links late and covered units to serviceable stock by station and prices the fix — expedite, rotable exchange or loan — with the date the shelf would run short.

  • Never books an exchange or changes a minimum
Vendor scorer

Scores every shop on turnaround, on-time delivery, quotes against history, no fault found and warranty claims accepted, and drafts the quarterly review notes.

  • Proposes watch rules; never changes a contract
Component Repair Manager and Director

Approve every claim, quote and stock action. The agents propose; a named person decides.

Ask in plain words

Ask about any unit, shop, quote or shelf

Ask in plain words, or tell the agents what to do. Every answer comes with its sources, and nothing goes to a shop until a person approves it.

Is IDG 7731 under warranty?

IDG S/N 7731 came off N812CV at 1,900 hours. Meridian's §9.2 warrants it for 4,000 hours or 18 months, so the $48,200 quote should be claimed, not paid.

Which shops are late?

63 units are past contract turnaround. The worst: air cycle machine S/N 5012, 44 days at Cobalt against 25, two reminders unanswered. Follow-ups for 5 more are drafted on Shops.

Where will a shelf run dry?

Two shelves are below minimum: IDG at ORD (2 of 3) and the APU at SFO (0 of 1). The options are priced on Pool.

What if Meridian denies it?

The Claim drafter drafts a rebuttal from the teardown and §9.2 for Owen Brandt to review, and the reply clock keeps running: 30 days from sending. The quote stays rejected until a person decides otherwise.

Governance

Rotable repair management you can audit: cited, checked twice, signed.

Every value cites its sourceEach finding, quote line and claim statement links to the passage it came from — the contract clause, the Form 8130-3, the tech log, the teardown, the quote or the repair history.
Every warranty finding checked twiceThe Verifier re-derives each warranty and quote finding from the records without seeing the first working. If the two disagree, the person deciding sees both.
No quote before the warranty gateA quote cannot be approved until the Warranty checker and the Verifier have both run against the last repair and the shop's own clause. A covered unit becomes a drafted claim, not a purchase order.
A named person decides and signsApprovals, counters, rejections, holds and claims each take a reason code and a signed statement. Above $75,000 the Director of Materials co-signs.
Agents propose; people sendThe agents read, compute, draft and propose. They never send, approve, reject, book, pay or change a minimum. The one exception is a first reminder to a late shop, sent under a standing approval a person set — and logged.

Questions

What component teams ask about rotable repair management.

What is Rotable Repair Management?

Rotable Repair Management tracks each rotable from removal through repair and warranty back to stock, for component teams. Eight AI agents put every serialized unit on one repair loop, check warranty against the shop's clause and the release certificate before any quote is approved, set quotes against past repairs, chase late shops from their own contracts, protect the shelf and draft warranty claims. The component repair manager approves, edits or rejects every claim, quote and routing.

How does it stop us paying for a repair that is still under warranty?

No quote can be approved until two agents have checked warranty. The Warranty checker finds the last repair order, its FAA Form 8130-3 or EASA Form 1 and the shop's warranty clause and counts flight hours, cycles and months; the Verifier re-derives it from the records on its own. A covered unit becomes a drafted warranty claim with the evidence attached, not a purchase order. The component warranty claim goes to the shop before any money goes out, instead of being chased after the invoice is paid.

How does it review a repair shop's quote?

The Quote analyst reads the teardown and sets each quote line against past repairs of the same part number with the same finding, across every shop, and against contract caps. In the working solution a $48,200 generator quote sat 54% over a $31,400 median, with a rotor assembly replaced in only 1 of 12 past repairs. It drafts the counter or the rejection; a person decides.

How does it track repair turnaround time and late shops?

Repair order tracking runs to the shop and back: every unit at a shop shows its days against the contract turnaround, the shop's last message and the promised date. The Shop follower drafts follow-ups from each agreement's turnaround clause, reads the replies and drafts the escalation the contract allows. A shop portal that does not answer shows as an error with a retry, so stale data is visible.

Does it help with rotable pool management, exchanges and float stock?

Yes. The Pool planner links every late or covered unit to serviceable stock by station and prices the cheapest fix — an expedite, a rotable exchange from the pool or a loan — with what each costs. The rotable pool planner approves the option and is the one who changes a station minimum. The aim is 10% less float on covered part numbers.

Do people stay in control?

Yes. The agents read, compute, draft and propose; they never send, approve, book or pay. Every approval, counter, rejection and claim takes a reason code and a signed statement, the Director of Materials co-signs above $75,000, and only first reminders to a late shop go out under a standing approval a person set.

Which systems and forms does it work with?

It reads the maintenance & engineering system, the electronic tech log, purchasing and accounts payable, shop portals and vendor e-mail, ATA Spec 2000 repair order messages, carrier tracking and the document store that holds FAA Form 8130-3, EASA Form 1, teardown reports and repair agreements. Routing follows each shop's 14 CFR Part 145 ratings.
