Zelazny Services

Marcin Zelazny

Owner, Zelazny Services LLC

I spent 17 years at Bombardier in three roles that all came back to the same question: does the paperwork match the airplane? I started as a technician, became an inspector, and finished as a quality researcher chasing the kind of nonconformances that don't show up until two owners later.

I started Zelazny Services because the same patterns I saw inside an OEM show up everywhere — incomplete logbook entries, AD compliance that's been "verified" by no one in particular, modifications without 337s, maintenance tracking that disagrees with the books. Buyers usually don't have the time, the bandwidth, or the records-reading reps to catch these in a 30-day due-diligence window.

That's what I do. Read records carefully. Cross-check against the logbook. Write up what I find — what's verified, what's not, what's open, what's worth a follow-up question to the seller or the MRO. Plain language, with citations to the source page.

Background

  • 17 years at Bombardier — technician, inspector, quality researcher
  • Aircraft families with hands-on experience: [CONFIRM specific models]
  • Certifications: [CONFIRM — e.g., FAA A&P, IA, manufacturer training]
  • Based in Connecticut, working with clients across the US and internationally

How I work

  • Records are the truth. The logbook is the legal record. The maintenance tracking system is a reference, not a source. CAMP, CMP, Camo — all useful, none authoritative.
  • Serial number is identity. Tail numbers change. S/Ns don't. Every report I write is indexed by serial number first.
  • Advisory only. I do not perform inspections, sign 8130-3s, or determine airworthiness. That's deliberate — it keeps my opinion independent and your A&P / IA / DAR in their proper role.
  • Findings, not conclusions. I tell you what the records say. You decide what to do about it. If I think a finding deserves a phone call to the MRO, I'll say so — and recommend who should make it.
  • Tools as leverage, not authority. I use OCR, search, and AI-assisted pattern-spotting to read faster and miss less. Every finding still has a page reference back to a source document.

What I won't do

  • Sign for work I didn't perform
  • Borescope, leak-check, run-up, or otherwise touch the aircraft
  • Make a recommendation to buy or not buy — that's your call
  • Write to a conclusion the records don't support, regardless of who's paying
  • Take an engagement where the scope of work isn't written down before I start

Best way to start a conversation: the intake form — it asks the questions I'd ask on a first call anyway.
