Robinson R44 buyer's guide:
what the records reveal

The U.S. fleet at a glance

The FAA registry lists 1,868 Robinson R44 aircraft, built between 1992 and 2026. The largest concentrations are registered in TX (294), DE (143), FL (136). 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.

Type specifications (FAA Type Certificate)

Representative type specifications — values can vary by serial/variant. Verify against the official FAA Type Certificate Data Sheet (drs.faa.gov, document H11NM).

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 Robinson R44 fleet, 84 reports have been filed against this type since 1997 — most airframes have zero reports on file, with a mean of 0 per airframe. The systems mechanics report most on this type:

• JASC 62 — Main Rotor : 15 reports fleet-wide
• JASC 85 — Reciprocating Engine : 11 reports fleet-wide
• JASC 74 — Ignition : 10 reports fleet-wide
• JASC 78 — Exhaust : 5 reports fleet-wide
• JASC 67 — Rotorcraft Controls : 5 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: 1,461 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 159 accident or incident records serial-matched to Robinson R44 airframes in this fleet since 2008 — about 8.5 per 100 currently registered aircraft, of which 17 involved fatal injuries (most recent record: 2026). A further 16 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

31 airworthiness directives published since 1994 in our Federal Register database and matched to this type are currently open, including 8 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 2025-11-07 recurring · effective 2025-07-11 — The FAA is superseding Airworthiness Directive (AD) 2024-19-11 for all Robinson Helicopter Company Model R44 and R44 II helicopters. AD 2024-19-11 required visually inspecting a certain flex plate assembly (flex plate) and certain clutch shaft forward yokes (yokes), including each flex plate bolt, and depending on the results, taking corrective actions. AD 2024-19-11 also required removing certain yokes from service within a specified threshold, or as an alternative, performing in-depth inspections. Since the FAA issued AD 2024-19-11, it has been determined that clarifications regarding the al
• AD 2024-23-01 · effective 2025-01-07 — several reports of failed clutch actuators and failed rivets attaching the belt tension clutch actuator brackets (bracket) to the fan scroll housing
• AD 2024-20-03 · effective 2024-11-29 — reports of engine governor failure, which was a result of water intrusion inside of the governor controller
• AD 2024-04-02 recurring · effective 2024-04-02 — reports of helicopters losing a tail rotor blade (TRB) tip cap
• AD 2022-19-12 · effective 2022-10-20 — same action
• AD 2022-12-08 · effective 2022-06-29 — reports of intermittent or abnormal operation of the engine revolutions per minute (RPM) governor (governor)

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, 585 of the 1,868 observed Robinson R44 airframes — 31.3% — 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 Robinson R44

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

1. Inspect the main rotor closely — it is among the most-reported systems for this type in FAA Service Difficulty Reports (15 reports fleet-wide).
2. Inspect the reciprocating engine closely — it is among the most-reported systems for this type in FAA Service Difficulty Reports (11 reports fleet-wide).
3. Inspect the ignition closely — it is among the most-reported systems for this type in FAA Service Difficulty Reports (10 reports fleet-wide).
4. Verify in the logbooks that the 8 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.
