MRO Operations
Zero-failure programs where certification, partners, and supply chains must execute against gated evidence.
Inside this journey
-
Pre-Discovery
Align the room on outcomes, decision process, and constraints before deeper discovery.
-
Stakeholder Alignment

Alignment Questions
Quick Passenger Manifest — Who’s in the Room?
- Which role are you representing in this conversation?
- How many aircraft in your fleet will potentially touch this program (by type or fleet size)?
- Which primary platforms are in scope for your upcoming heavy checks?
- When are your next scheduled C‑ or D‑checks that triggered this conversation?
- Tell us in your own words: what prompted you to explore an outside MRO partner now?
Are You Comfortable Betting On Current Turnarounds?
- When you commit an aircraft to a heavy check, how confident are you that the provider will meet the promised redelivery window?
- What examples can you share of a provider missing promised turntimes—and what were the downstream impacts?
- How do you currently allocate financial exposure for late redelivery (e.g., reserve aircraft, lease, contractual penalties)?
- If you could change one thing about the way turntimes are guaranteed or enforced, what would it be?
What’s Really at Stake When a Check Runs Late?
- Beyond the immediate AOG loss, what consequences from an overrun keep you awake at night?

Where Parts Shortages Bite the Most
- If parts availability is the single biggest bottleneck, which families create the most pain (airframe, engine, landing gear, specific rotable groups)?
- What are your typical lead times for critical rotable items today, and how often do they slip?
- Do you prefer providers to hold dedicated rotable pools for you, or to work on a just‑in‑time sourcing model?

- Which metric best captures the pain from overruns for you (choose one)?
Who's Holding the Keys — and the Budget?
- Where do deals typically stall in your organization—technical approval, commercial terms, or executive sign-off?
- List the people who must approve or influence a multi-year heavy-maintenance agreement (roles or names).
- What approval threshold (value or contract length) triggers executive committee review in your organization?
- How important is having guaranteed turnaround times with financial penalties in your decision—must-have, nice-to-have, or low priority?
- What commercial model do you prefer when shifting heavy-check risk—PBH, fixed-price per check, T&M with cap, or hybrid?
- What procurement constraints or required contract clauses commonly derail negotiations at the final stage?
Where Do Your Slots and Hubs Actually Leak?
- How flexible are your preferred maintenance windows at each hub—can you shift aircraft by days, weeks, or not at all?
- Which hubs or stations are non-negotiable for maintenance due to network importance or crew logistics?
- What hub constraints have surprised you before (e.g., runway, gate, local regulations, curfews)?
- How much ferrying of aircraft between hubs are you willing to accept to secure a slot (none / short haul / long haul)?
- Describe one past instance where sloting or hub constraints forced an expensive workaround—what was the workaround and cost driver?
- Do regulatory or customer-specific KTs (e.g., cargo handling, special configs) create additional slot lead time for your fleet?
Parts, Rotables, and the Heartbeat of Turnaround
- How confident are you that rotable availability—not labor or slots—is the single largest risk to on-time redelivery?
- What is your current approach to rotable provisioning for heavy checks?
- Which components have historically driven the longest lead-time delays for your fleet (select all that apply)?
- What average lead time for critical spares do you consider acceptable to meet your redelivery targets?
- Would you consider a consignment/PBH mix where we hold critical rotables at our base for guaranteed availability?
- Estimate the operational cost (or impact) you assign to a single AOG day for a narrowbody and for a widebody.
What Keeps You Awake at 2 AM?
- If a guaranteed redelivery failed and you incurred a penalty, would you prefer a larger monetary penalty or faster remediation and flight recovery?
- How tolerant is your leadership of scope creep or additional findings discovered during checks?
- What percentage over initial estimate for time or cost would you accept before automatic escalation is required?
- Which quality standards and audits must our facilities meet for you to consider them (select all that apply)?
- How do AOG events affect you emotionally and operationally—what stressors escalate internally?
- Have you previously accepted a remediation or 'workaround' that later created recurrent issues? Tell us what happened.
If It Worked Perfectly, What Would You Stop Worrying About?
- Imagine handing us your next heavy-check program—what would you most want us to remove from your inbox and mind?
- Which SLA/KPI would make you feel genuinely confident that the program is succeeding (select up to three)?
- How frequently would you want operational updates during a check (choose one)?
- What does an acceptable post-check handover look like—what documents, tests, and sign-offs matter most?
- Which governance cadence would give you comfort post-deployment (select one)?
Readiness and Next Steps — Can We Make This Real?
- What's the single biggest barrier that would stop you from selecting an external MRO partner today?
- Would you be open to a pilot: one or two aircraft to validate our processes before a full multi-year commitment?
- Which documents do you require before operational sign-off (e.g., maintenance plan, risk register, parts list, insurance certificates)?
- Realistically, what is your internal timeline to reach a decision for a 12–36 month agreement?
- Who else in your organization should receive our detailed proposal or attend a technical walkthrough?
- What would you need to see in our first proposal to feel comfortable scheduling a site visit or pilot (key must-haves)?
