Bell 407 buyer's guide:
what the records reveal

The U.S. fleet at a glance

The FAA registry lists 964 Bell 407 aircraft, built between 1996 and 2025. The largest concentrations are registered in TX (116), LA (105), CO (88). A large, active fleet works in a buyer's favor: parts supply, mechanic familiarity and comparable sale prices are all easier to establish than on a rare type.

Where this fleet reports maintenance difficulties

FAA Service Difficulty Reports are filed by mechanics and operators when a component fails or malfunctions in service. Across the Bell 407 fleet, 2,151 reports have been filed against this type since 1996 — most airframes have zero reports on file, with a mean of 2.2 per airframe. The systems mechanics report most on this type:

• JASC 63 — Main Rotor Drive : 292 reports fleet-wide
• JASC 72 — Engine : 205 reports fleet-wide
• JASC 32 — Landing Gear : 199 reports fleet-wide
• JASC 65 — Tail Rotor Drive : 187 reports fleet-wide
• JASC 62 — Main Rotor : 184 reports fleet-wide

Filing is voluntary, so these figures understate reality — but the RELATIVE weight of each system is exactly where an experienced buyer points the pre-buy inspection first. Reconciliation note: 1,233 further reports filed under these registrations were excluded because the aircraft model declared in the report shows they belong to previous holders of the same N-numbers.

The accident record, in numbers

The NTSB database holds 47 accident or incident records serial-matched to Bell 407 airframes in this fleet since 2008 — about 4.9 per 100 currently registered aircraft, of which 6 involved fatal injuries (most recent record: 2026). A further 17 records filed under the same N-numbers belong to different airframes (reused registrations) and are excluded.

Method: the denominator is the fleet currently on the FAA registry. Airframes destroyed and later deregistered leave that denominator, so this ratio understates lifetime accident history — read it as a fleet-profile indicator, not an accident rate. Fleet totals also reflect how the type is flown (training and commercial work versus private use), not just the machine itself.

Fleet-level counts tell you about the TYPE; what matters for your purchase is whether the specific airframe you are considering appears in that database — and U.S. registrations get reused, so a serial-number check matters. That per-aircraft lookup is exactly what a TailGuard report does.

Airworthiness directives to know about

38 airworthiness directives published since 2000 in our Federal Register database and matched to this type are currently open, including 7 recurring directives that must be re-complied with at set intervals. The full list of directives applicable to an older airframe is longer — build it at drs.faa.gov. The most recent in our database:

• AD 2026-10-04 · effective 2026-06-25 — one-time detailed visual inspection of the electrical harnesses for chafing and corrective actions if necessary
• AD 2025-13-01 · effective 2025-07-08 — report that certain expandable blade bolts installed on the main rotor blade may not have received the correct heat treatment, which could result in stress corr
• AD 2024-10-12 · effective 2024-08-22 — report that a certain part-numbered fuel system standpipe assembly (standpipe) may have sharp edges at the interval weld joints due to a quality escape during t
• AD 2023-17-51 · effective 2023-09-21 — report of a disbonded area in a tail rotor (T/R) blade
• AD 2022-27-08 · effective 2023-01-12 — accident
• AD 2022-23-02 recurring · effective 2023-01-03 — establishing a maximum accumulated Retirement Index Number (RIN) count for certain crosstube assemblies and revising the ALS of the existing m

Superseded directives are excluded from these counts. Directives apply by type — no database can tell you whether a given airframe complied. Only its logbooks can, and that is the single most important paperwork check of your pre-buy.

Ownership turnover

Comparing monthly FAA registry snapshots from Aug 2023 to Jun 2026, 257 of the 964 observed Bell 407 airframes — 26.7% — changed registrant at least once. This includes registrant-name changes that are not market sales — such as a transfer to an owner's LLC or trust — and newly delivered aircraft registered to their first buyer within the window. A recent ownership change is not a red flag by itself, but a rapid succession of owners deserves a direct question to the seller, and the registration timeline of the specific aircraft is worth reading before you negotiate.

Before you buy a Bell 407

A records-driven starting checklist for this type — derived from the figures above, to hand to your mechanic:

1. Inspect the main rotor drive closely — it is among the most-reported systems for this type in FAA Service Difficulty Reports (292 reports fleet-wide).
2. Inspect the engine closely — it is among the most-reported systems for this type in FAA Service Difficulty Reports (205 reports fleet-wide).
3. Inspect the landing gear closely — it is among the most-reported systems for this type in FAA Service Difficulty Reports (199 reports fleet-wide).
4. Verify in the logbooks that the 7 recurring airworthiness directives matched to this type are signed off at the required intervals.
5. Confirm engine and airframe times against the logbooks and the most recent annual inspection.
6. Have a licensed A&P/IA perform a physical pre-purchase inspection — no records check replaces it.
