The FAA's Part 135 SMS Deadline Is May 28, 2027 — What Helicopter Operators Need in Place
The FAA's Part 135 SMS deadline is May 28, 2027. Here's what a helicopter operator needs in place.
Under the FAA's Part 5 rule, every Part 135 certificate holder and every §91.147 air tour operator must have a Safety Management System implemented — and a signed declaration of compliance filed with the FAA — by May 28, 2027. That is under nine months from today. If your operation flies helicopters for air medical, charter, utility, or tours, this is your deadline, and the declaration is signed by your accountable executive.
- The rule
- 14 CFR Part 5, Safety Management Systems — published April 26, 2024, effective May 28, 2024.
- Who
- Part 135 certificate holders, §91.147 commercial air tour operators, and certain Part 21 design and manufacturing certificate holders.
- Deadline
- Part 135 and §91.147 operators: SMS developed and implemented by May 28, 2027 — 36 months from the rule's effective date.
- The filing
- A declaration of compliance to your local FAA office — operator name, certificate number, address, and a statement that the SMS is implemented — signed by the accountable executive or a senior manager.
- Single-pilot
- Covered. A single-pilot operator who is the sole person responsible for the aircraft can apply the excepted sections in §5.9(e); a single-pilot operator with employees meets the full rule.
Who this reaches in the rotorcraft world
The rule is written around certificates, not aircraft types, so it lands unevenly across helicopter operations. Air medical programs flying under Part 135 are squarely inside it. So are charter and utility operators holding a 135 certificate, and any operator conducting commercial air tours under §91.147. Tour operators who never thought of themselves as “SMS organizations” are the group most likely to be surprised.
Public aircraft operations — fire, law enforcement, and county rescue flying as public aircraft — are not covered by the Part 5 mandate. Two cautions there. First, many public-safety programs also run a Part 135 side (air medical is the common one), and that side is covered. Second, the FAA maintains a voluntary SMS program, and most public-safety aviation units adopt SMS on their own terms because the safety case is the same whatever the regulatory basis. If you are not certain which of your operations fall under the rule, that is a question for your FAA Flight Standards office, and it is worth asking now rather than in the spring.
What “implemented” actually means
The declaration does not say you have a manual. It says the system is running. Part 5 is built on four components, and each one produces artifacts an inspector can ask to see.
A signed policy from your accountable executive with safety objectives, a commitment of resources, an employee safety-reporting policy, a definition of unacceptable behavior, an emergency response plan, and — new in this rule — a code of ethics.
A repeatable process to analyze your operation, identify hazards, assess the risk, decide on controls, and judge whether the remaining risk is acceptable. In a helicopter operation, this is where a real flight risk assessment lives.
Monitoring that the controls work: audits and evaluations, investigation of incidents and non-compliance, a confidential employee reporting system, and corrective action that closes the loop. This is the component that generates the records.
Training so every person understands their part of the SMS, and communication that keeps hazard information moving through the organization — safety meetings, briefings, and acknowledged documents.
Underneath all four sits a record-keeping requirement (§5.97). The practical test is simple: if an inspector asked for last quarter's hazard reports, the risk assessment on your highest-exposure mission profile, and evidence that a corrective action was actually completed, could you produce them in ten minutes?
Where operators run out of runway
Having watched safety programs from the cockpit side for more than a decade, the failure modes are consistent. The manual gets written and the system never gets used. Hazard reports go into a binder or an inbox and nobody can show what happened next. Flight risk assessments are filled out on paper after the fact. Training happens, but there is no record of who completed what. None of that survives a declaration signed by your accountable executive, because the declaration is a statement that the system is operating — and it carries that person's name.
Working back from May 28, 2027, a realistic timeline for a small or mid-size operator looks like this:
- Fall 2026 — gap analysis. Map what you do today against the four components. Identify the accountable executive and write the policy. Decide how hazard reports and risk assessments will actually be captured.
- Winter 2026–27 — stand it up. Turn on employee reporting, run risk assessments on real flights, hold and document safety meetings, start training records.
- Spring 2027 — run it before you declare. Two or three months of live records is what makes the declaration true. Do not sign it on the day the binder is finished.
How HERO Aviation fits
HERO Ops is an operational safety platform built for the people flying the mission, and it is organized around the same four components the rule is. Hazard reporting from a phone at the landing zone, with a status trail from report to corrective action. A flight risk assessment that pulls live weather for the route, scores the flight, and routes elevated scores to a supervisor. A running record of preflights, risk assessments, safety meetings, and controlled documents that you can export when someone asks for them. Training and document acknowledgment so the “who has read what” question has an answer.
Our Fatigue Exposure module is worth being precise about. It is built only from the duty and schedule records an operation already keeps — hours on duty, rest before duty, day of hitch, night launches, planned departure and return, and flight time against the operator's own limits — and it presents an exposure index, with the factors behind it, as one more input for the crews and supervisors who make the decision. It is informational. It is not a fitness-for-duty determination, not a medical assessment, and not a clearance of any kind.
See the platform running on a live helicopter operation, and walk away with a gap list you can act on.
Request a DemoQuestions we get asked
Does the rule apply to a single-pilot Part 135 operator?
Yes. A single-pilot operator who is the only person responsible for the safe operation of the aircraft can use the excepted sections in §5.9(e), which relax parts of the internal-communication and management-duty requirements. A single-pilot operator with employees meets the full rule.
Is there a separate implementation-plan submission for Part 135?
The submission the rule requires from Part 135 and §91.147 operators is the declaration of compliance, filed once the SMS is implemented, by May 28, 2027. Your FAA office can confirm what they expect to accompany it.
We are a public-safety agency. Do we have to do this?
Public aircraft operations are not covered by the Part 5 mandate. If your agency also holds a Part 135 certificate, that operation is covered. Many public-safety units adopt SMS voluntarily regardless, and the FAA's voluntary program exists for that purpose.
