A Part 145 FAA surveillance inspection conducted under the FAA's Safety Assurance System (SAS) typically walks eight document categories in this order: (1) Repair Station Manual with revision log (§145.207–§145.209); (2) Quality Control Manual with change history (§145.211); (3) current ratings and — for limited ratings — the capability list (§145.59, §145.215); (4) personnel roster and FAA certificate copies (§145.161); (5) individual training records and training program (§145.163); (6) equipment and tool calibration logs (§145.109(b)); (7) work orders and return-to-service records (§145.219, §43.9); and (8) contract maintenance list and contractor qualification evidence (§145.217).
The most commonly cited findings are QCM revision drift, missing individual training signoffs, and parts receiving documentation gaps — all administrative failures the right binder system prevents before the inspector arrives. FAA civil penalties reach $75,000 per violation — $1,875 for individuals and small business concerns — under 49 U.S.C. § 46301(a)(1) and 14 CFR §13.301 (violations on or after December 30, 2024).
Most surveillance findings are documentation problems, not maintenance problems
In published enforcement actions, repair stations that lose their certificates have commonly failed first on manual currency (§145.207–§145.211) or §145.219 recordkeeping — not on the quality of the underlying maintenance work. The binder is the proof the work was done right. Without it, the work didn't happen in the eyes of the FAA.
Why the Inspector's Walk Order Matters
The FAA's Safety Assurance System (SAS), described in FAA Order 8900.1 Volume 10, structures Part 145 surveillance around a hierarchy of elements. The Principal Maintenance Inspector (PMI) starts at the certificate-level governance documents — the RSM and QCM — because everything else the station does flows from those manuals. If the manual is stale, the inspector doesn't need to look at work orders to know the QC system is compromised.
The sequence then moves outward: from the station's self-defined procedures (the manuals) to the authorizations those procedures operate under (capability list, ratings), to the people who execute them (roster, training records), to the tools those people use (calibration), to the work product (work orders, return-to-service records), and finally to work the station contracted out (contract maintenance). Each layer validates the one before it.
The implication for audit prep is structural: a finding in Tab 1 (RSM) infects every subsequent tab. A PMI who discovers the repair station is operating on a superseded QCM revision will re-examine every work order from the period the revision was stale — because every return-to-service approval made under a non-current QCM is potentially non-conforming. Assembling the binder in the inspector's walk order makes gaps visible before the visit, so they can be remediated rather than explained.
Governing regulatory framework for this guide
This guide applies to all certificate classes under 14 CFR Part 145 — Airframe, Powerplant, Propeller, Radio, Instrument, Accessory, Limited, and Specialized Service. Stations with multiple rating classes carry this binder requirement for each rating. The guide is also the repair-station companion to the Part 135 surveillance framework — operators that hold both a Part 135 Air Carrier Certificate and a Part 145 Repair Station Certificate may face both types of inspection in the same calendar year, often by the same PMI.
The 8-Tab Audit Binder: Document by Document
Each tab below corresponds to a document category walked during a SAS EPI. Build the binder in this order — gaps become visible before the inspector does.
Repair Station Manual (RSM) + Revision Log
The RSM is the certificate-level operating document, required by §145.207 with its contents specified in §145.209. The PMI verifies the station holds the current version acceptable to the FAA — not a draft or a superseded revision — and that it is accessible to personnel. The revision log should show every amendment and its date, following the §145.209(j) revision procedures, including notifying the responsible Flight Standards office; controlled-copy distribution records are the standard practice for proving the current revision reached all relevant personnel.
Documents the PMI Will Request
- Current RSM with revision number and FAA acceptance date on the cover page
- Complete revision history log from original acceptance to present
- Distribution records showing the current revision was issued to all holders
- Any pending revision requests submitted to the FSDO
How the PMI Tests This Tab
The PMI will compare the revision number in the binder against the Flight Standards office's record. Operating on a manual that is not current and accessible to personnel is a §145.207 finding, and revisions made without following the §145.209(j) revision procedures and FAA notification are findings as well.
Most Common Finding
Running on a revision the FAA has not yet found acceptable, or revising the manual without following the §145.209(j) revision procedures and notification.

The Five Finding Categories That Trigger Most Part 145 Enforcement Actions
Published FAA enforcement actions and order guidance point to a consistent list. These five categories are among the most commonly cited in civil penalty actions and certificate suspensions against Part 145 certificate holders. None involve the quality of the underlying maintenance work — all five are administrative documentation failures.
QCM / RSM Revision Drift (§145.209, §145.211)
14 CFR §145.209 / §145.211Running on a superseded revision of the Quality Control Manual or Repair Station Manual is among the most commonly cited findings in FAA surveillance of repair stations. The failure mode is almost always organizational: a revision is drafted, submitted to the Flight Standards office, and accepted — but the old revision remains in circulation because the distribution log was not completed or distribution sign-offs were not collected. The PMI sees revision X in the binder, checks the FAA file, and finds revision Y was accepted two months ago. Everything done under the old revision is now suspect.
Individual Training Record Gaps (§145.163)
14 CFR §145.163The repair station's training program document may be current and comprehensive, but if documented individual training records are missing for even one covered employee — or recurrent training is not tracked to currency dates — the §145.163 requirement fails for that individual. The station cannot approve return to service using a person whose training currency cannot be demonstrated. Any return-to-service approval signed by someone with a training gap becomes suspect retroactively.
Parts Receiving Inspection + 8130-3 Documentation Gaps (§145.211(c)(1)(i))
14 CFR §145.211(c)(1)(i) / §145.219FAA Form 8130-3 is the primary chain-of-custody document for most aircraft parts entering a repair station. A part installed in maintenance with no receiving inspection record or traceability on file is, at best, a quality control system finding under §145.211 and, at worst, a Suspected Unapproved Parts (SUP) matter handled under FAA Advisory Circular 21-29D. The most common variant: a part was received, the 8130-3 was filed at receiving, the part sat in bench stock for several months, and the tag was separated from the part before installation. The work order has no traceability document.
Incomplete Work Order Records (§145.219 / §43.9)
14 CFR §145.219 / §43.9A completed and signed work order missing a required field — the description of work performed, the completion date, the name of the person performing the work (if other than the approver), or the signature, certificate number, and kind of certificate of the approving person — fails the §145.219 content requirement under 14 CFR §43.9. Missing parts-used lists or article serial numbers are best-practice gaps that can make the required work description inadequate. This is not a maintenance quality problem; it is a recordkeeping problem. The PMI pulls a sample of completed work orders and checks each field. Consistent gaps across the sample indicate a systemic process failure rather than an isolated omission.
Equipment Calibration Exceedances (§145.109)
14 CFR §145.109Any measuring or test instrument found in active shop use past its calibration due date is a §145.109 finding on the spot — the PMI does not wait for the binder review. The station must then answer the harder question: was this instrument used in any maintenance performed during the period it was overdue? Any such work may need to be re-inspected. The calibration master log exists precisely to prevent this scenario by surfacing upcoming due dates before they become overdue dates.
How a Compliance Document Platform Assembles the Binder Automatically
The eight-tab binder described above is not a one-time deliverable — it must stay current between every surveillance visit. A QCM revision issued six weeks before the inspection must be reflected in Tab 2 with its distribution log. A new employee onboarded last month must appear in Tab 4 with OJT signoffs in Tab 5. A torque wrench re-calibrated last week must be updated in Tab 6.
FileFlo is a compliance document intelligence platform that keeps each binder tab live rather than assembled under pressure. When a document is uploaded — a QCM revision, a training certificate, a calibration cert, a 8130-3 tag — FileFlo classifies it against the relevant CFR subpart and files it in the correct binder section. The platform tracks expiration dates on training currency, calibration cycles, and contract maintenance approvals, surfacing upcoming expirations at 90, 60, and 30 days so gaps are remediated before the inspection, not disclosed during it.
Every QCM change tracked with version number, FAA acceptance date, and distribution log. Revision drift surfaces immediately.
Individual training records with initial, OJT, and recurrent currency dates. 90/60/30-day alerts fire before a currency lapses.
Calibration master log with each instrument's due date tracked. Alerts prevent the floor inspection finding.
Work orders classified against §43.9 content requirements. Missing-field alerts before a return-to-service record closes with a gap.

Frequently Asked Questions
What documents does an FAA inspector ask for during a Part 145 surveillance inspection?
Under the FAA's Safety Assurance System (FAA Order 8900.1 Volume 10), a Principal Maintenance Inspector (PMI) conducting a surveillance inspection at a Part 145 repair station will typically request: (1) the current Repair Station Manual (RSM) and Quality Control Manual (QCM) with revision history under 14 CFR §145.207–§145.209 and §145.211; (2) the Air Agency Certificate, current ratings, and — for stations with limited ratings — the capability list under §145.215; (3) the contract maintenance list and contractor qualification evidence under §145.217; (4) the roster of management, supervisory, inspection, and return-to-service personnel under §145.161; (5) training program documentation and individual training records under §145.163; (6) equipment and tool calibration logs under §145.109(b); (7) work order records and return-to-service documentation under §145.219; and (8) FAA Form 8130-3 tags and parts receiving inspection records under the station's quality control system (§145.211(c)(1)(i)). The most commonly cited findings are stale RSM/QCM revisions, missing individual training signoffs, and parts receiving documentation gaps.
What does 14 CFR §145.211 require in the Quality Control Manual?
Per 14 CFR §145.211(c), a certificated repair station must have and follow a quality control system with a manual that covers: procedures for inspecting incoming raw materials to ensure acceptable quality; preliminary inspection of all articles maintained; inspecting articles involved in an accident for hidden damage; final inspection and return to service of maintained articles; procedures for calibrating measuring and test equipment, including the intervals at which equipment is calibrated; procedures for taking corrective action on deficiencies; procedures for revising the manual; and the proficiency of inspection personnel. The QCM must be acceptable to the FAA, and the station must notify its responsible Flight Standards office of each manual revision per §145.211(d). QCM version control failure — running on a superseded revision — is one of the most commonly cited findings in FAA surveillance of repair stations.
How long must a Part 145 repair station keep maintenance records?
Under 14 CFR §145.219(c), a certificated repair station must retain records of all maintenance, preventive maintenance, alterations, and required inspections for at least 2 years from the date the article is approved for return to service. Under §145.219(a), the records must demonstrate compliance with part 43; per 14 CFR §43.9(a), each record must include: a description of the work performed; the completion date; the name of the person performing the work if other than the approving person; and the signature, certificate number, and kind of certificate held by the person approving the return to service. Digital storage with auditable revision history is the lowest-cost path to satisfying both the §145.219 retention minimum and the §145.219(d) requirement to make records available to the FAA on request. Retaining FAA Form 8130-3 tags with the record is standard traceability practice that supports the part 43 documentation requirement.
What is a SAS Element Performance Inspection (EPI) at a Part 145 repair station?
The Safety Assurance System (SAS) is the FAA's risk-based oversight framework described in FAA Order 8900.1 Volume 10 (Safety Assurance System Policy and Procedures). Within SAS, an Element Performance Inspection (EPI) is a structured inspection that evaluates specific elements of the repair station's certificate against documented performance standards. An EPI works through the station's governing documents — from the Repair Station Manual through capability ratings, training, recordkeeping, and parts control — and documents findings against each element. In practice, the document categories the inspector requests during any FAA surveillance visit to a repair station are the same; the EPI adds the SAS data-collection formalism. The binder content that satisfies a SAS EPI satisfies a routine surveillance inspection.
What are the most common Part 145 FSDO findings?
Commonly cited Part 145 surveillance findings include: (1) QCM/RSM revision control failure — running on a superseded revision or not following the required revision procedures (§145.209(j), §145.211); (2) training documentation gaps — missing individual training records or recurrent training not tracked to currency dates (§145.163); (3) parts receiving inspection gaps — inbound parts with no receiving inspection record or missing FAA Form 8130-3 traceability, contrary to the station's own quality control manual procedures (§145.211(c)(1)(i)); (4) work order recordkeeping deficiencies — incomplete work orders, missing return-to-service signatures, or records not available within the 2-year retention window (§145.219); and (5) equipment calibration gaps — measuring and test equipment used in maintenance with expired or undocumented calibration cycles (§145.109). These five categories appear repeatedly in FAA civil penalty actions against Part 145 certificate holders.
What FAA civil penalty applies to Part 145 violations?
Under 49 U.S.C. § 46301(a)(1), as amended by the FAA Reauthorization Act of 2024 (Pub. L. 118-63), the FAA may impose civil penalties of up to $75,000 per violation — or up to $1,875 per violation for individuals and small business concerns — for violations occurring on or after December 30, 2024, per the inflation-adjusted schedule in 14 CFR §13.301 (amounts adjusted annually under the Federal Civil Penalties Inflation Adjustment Act). Repeat or systemic findings can result in suspension or revocation of the repair station certificate under 49 U.S.C. § 44709, with procedures in 14 CFR part 13. Published FAA enforcement actions against repair stations have included both settlements for isolated recordkeeping gaps and certificate actions for systemic QC manual failures. The asymmetric downside — one missed training signoff versus a civil penalty action — makes pre-inspection documentation investment structurally cost-positive at any shop size.
