2025 Robinson Helicopter Co R66
This page pulls together what public FAA and NTSB records show about one aircraft. It is for general research only. It is not a certified title search, an airworthiness or compliance check, or legal advice. Public records can be incomplete or wrong, and our matching does its best but is not guaranteed. Always confirm against the aircraft's official records and the FAA before you rely on anything here.
For privacy, we never show the owner's street address. Name and city or state only.
Log Hobbs and tach time, track oil changes, and keep this airframe's inspections and airworthiness directives in one place. A clean digital logbook and AD tracking built for owners.

Airworthiness Directives are mandatory safety fixes the FAA orders for a given model. These were issued for the Robinson Helicopter Co R66 model.
No matching airworthiness directives found in the FAA AD database.
This is a model-level list from public FAA data. It does not tell you which of these apply to this specific aircraft, or whether they have already been taken care of. That depends on the serial number, installed equipment, and configuration. Check each directive against the aircraft's own records.
Mandatory FAA safety fixes issued for the 250 engine family.

This list is matched to the engine family on file in the FAA registry, so it covers every variant in that family. It is from public FAA data and does not tell you which directives apply to this specific engine or whether they have been addressed.
This same N-number has been carried by more than one aircraft over the years. Each entry below is a different airframe that flew under this tail number, according to FAA records.
Serial RN068 · Md Helicopters Inc · Mesa, AZ
Serial 1484 · Ntm Foundation · Forest Grove, OR
Serial 1484 · Ntm Foundation · Forest Grove, OR
Built from public FAA registration and cancellation records, going back to 1980 (dates before that are unreliable). We can only show registrations the FAA formally cancelled, so there may be gaps. Not a certified title search.
Every N-number and owner this airframe has carried. We follow it by the serial number, which stays fixed even when the tail number changes hands.
Ntm Foundation · Forest Grove, OR
Recorded when the prior registration was cancelled with the FAA.
Ntm Foundation · Forest Grove, OR
Built from public FAA registration and cancellation records, plus our own daily snapshots of the FAA registry. Some owner changes never file a cancellation, so we recover them by comparing snapshots day to day. Those snapshots begin June 2026, so changes before then rely on FAA cancellation records and may be incomplete. This is registration history, not a certified title search.
Accidents and incidents on file for this specific aircraft, from two government sources. The NTSB investigates accidents and serious incidents. The FAA AIDS database logs a wider range of events. We tie NTSB reports to the aircraft by its serial number. AIDS reports do not include a serial number, so we attach one only when this aircraft was flying under that tail number on the day it happened (1980 onward).
No NTSB or FAA AIDS accident or incident reports found for this airframe.
Sources: the NTSB accident and incident database (matched by serial number and make) and the FAA AIDS database (attached through this aircraft's registration timeline and make, 1980 onward). FAA registration records have gaps, so an event that happened during a gap may not show up. This is what was reported to the NTSB and FAA at the time. It says nothing about the aircraft's condition or airworthiness today.
