VOLUME 4 AIRCRAFT EQUIPMENT AND OPERATIONAL AUTHORIZATIONS
CHAPTER 5 AIR AMBULANCE OPERATIONS
Section 1 Background and Definitions
4-916 INTRODUCTION. This chapter contains background information on air ambulance operations. It also contains information, direction, and
guidance to be used by inspectors, including principal operations inspectors (POI), when determining if an operator is eligible to hold out, advertise for, and conduct air
ambulance operations in accordance with Title 14 of the Code of Federal Regulations (14 CFR) part
as well as how to evaluate a helicopter air ambulance (HAA) operator’s compliance with 14 CFR part
135 subpart L
requirements. This chapter provides detailed guidance for the evaluation of an operator’s air ambulance procedures, air‑ambulance-specific sections of their
General Operations Manual (GOM), and the unique requirements an operator must meet prior to being issued Operations Specification (OpSpec) A021, Air Ambulance Operations—Helicopter;
or OpSpec A024, Air Ambulance Operations—Airplane. This chapter contains operational procedures for both airplane and helicopter air ambulance (HAA) operations. Specific
HAA training requirements are contained in several sections of Volume 3, Chapter 19. A sequential breakdown of this chapter follows:
A. Section 1. Contains general background information, such as air ambulance OpSpecs, definitions of terms, and references to source documents.
B. Section 2. Contains guidance for inspectors evaluating an operator’s initial request to be certificated as a part
operator or for existing operators to be issued OpSpec A021 or A024 for operations under
part 135 air ambulance service.
C. Section 3. Contains guidance for the evaluation of subject-matter-specific operational procedures pertaining to part
135 airplane or HAA services.
D. Section 4. Reserved. (Previously this section contained training information, which is now contained in Volume 3, Chapter 19.)
E. Section 5. Contains guidance to be used by inspectors when evaluating a part
operator’s risk analysis program.
A. Associations. The aviation and medical professions have combined various aspects of their industry to form a sophisticated system to
provide life-sustaining care for ill or injured people. Air ambulance operators have met the public need and demand for such services by equipping aircraft specifically
for this purpose. The Flight Standards Service (AFS), in consultation with air ambulance operators, medical care providers, and other industry organizations,
created specific OpSpec paragraphs to establish regulatory compliance standards designed to enhance safety in air ambulance operations. Most of these standards were later
codified under part
135 subpart L.
B. Emergency Operations. Situations will arise where a true medical emergency exists and no air carrier with an air ambulance
authorization is reasonably available. An air carrier without an air ambulance authorization may conduct an air ambulance operation to save a human life. That operator
must file a report with the local Flight Standards District Office (FSDO) within 10 days as required by part
The FSDO must investigate the circumstances and determine if an actual emergency appeared to exist at the time of the operation (see Volume 14, Chapter 1). Repeated air
ambulance operations by an operator without an air ambulance authorization should be determined as holding out to the public to conduct an operation which is not authorized
by their OpSpecs. (See paragraph 4-921, FAA Policy Regarding Compensation or Hire Considerations for Charitable Flights or Life Flights, for additional information.)
C. OpSpecs. Specific air ambulance OpSpecs (A021 for HAA and A024 for airplane air ambulance operations) are available to authorize
such flights. Operators who wish to provide air ambulance services must implement appropriate service-specific policies, procedures, training, and in some cases, install
equipment to facilitate safe air ambulance operations in accordance with regulations. These requirements are further discussed in this section and in the following sections
of this chapter.

4-920 OVERVIEW OF AIR AMBULANCE SERVICES. This paragraph provides a general overview of air ambulance operations. Details are
contained in the appropriate section of this chapter.
A. Regulatory Requirements. An air ambulance operator must comply with all requirements of the 14 CFR part under which
it is certified. Air ambulance operators are not exempt from any requirement of 14 CFR. To ensure industry standardization and a clear understanding between
the FAA and air ambulance operators, OpSpecs A021 (helicopter) and A024 (fixed wing) identify specific means by which air ambulance operators can comply with
14 CFR. Some of these rules are as follows:
1) Management Qualifications. Part
are required to have their management personnel identified per §
The pertinent parts of this section state (emphasis added):
(a) Each certificate holder must have
sufficient qualified management and technical personnel to ensure the safety of its operations. Except for a certificate holder using only one pilot in its
operations, the certificate holder must have qualified personnel serving in the following or equivalent positions:
(1) Director of Operations.
(2) Chief Pilot.
(3) Director of Maintenance.
(d) The individuals in the positions required
or approved under paragraph (a) ... of this section and anyone in a position to exercise control over operations conducted under the operating certificate must—
(1) Be qualified through training, experience
(2) To the extent required by their responsibilities,
have a full understanding of the following material with respect to the certificate holder’s operation—
(i) Aviation safety standards and safe operating practices;
(ii) Title 14 CFR Chapter I (Federal Aviation Regulations);
(iii) The certificate holder’s operations specifications;
(iv) All appropriate maintenance and airworthiness requirements
of this chapter (e.g., parts
this chapter); and
(v) The contents of the manual system required by §
(3) Discharge their duties to meet applicable
legal requirements and to maintain safe operations.
2) Certification Under a 14 CFR Part. Part
that the selection of the particular 14 CFR part used to certify an operator is to be based on the type and size of aircraft that the certificate holder
operates. An air ambulance operator must hold either a 14 CFR part
121 or part
carrier certificate and must then comply with all provisions of the specific part under which the operator is certified. The carriage of a person or persons
requiring medical personnel and/or medical equipment on a scheduled air carrier, operating under parts
does not constitute air ambulance operations. However, a scheduled air carrier transporting a person or persons requiring medical personnel and/or equipment
on an unscheduled flight (charter) is engaged in air ambulance operations. All HAA operations must be conducted under part
and specifically must comply with part
135 subpart L
in addition to general part
3) Certification Under Part
Most air ambulance operations are conducted under part
The information, direction, and guidance contained in this chapter applies to operations under part
135. If a
part 121 operator
requests air ambulance OpSpecs to apply to an airplane to be operated under part
the POI receiving that request should contact the Air Transportation Division (AFS-200) through the applicable RFSD for direction and guidance.
B. Advertising. According to §
an operator may not advertise or conduct operations not authorized by the operator’s operating certificate and OpSpecs. An operator without an air
ambulance authorization is explicitly prohibited, in OpSpec A004, Summary of Special Authorizations and Limitations, from conducting air ambulance operations.
C. OpSpec Paragraphs. All operators are initially prohibited by OpSpec A004 from conducting air ambulance operations.
Those who desire to advertise and/or conduct air ambulance operations must have this prohibition removed through the issuance of the appropriate air
ambulance OpSpecs. Operators holding part
but without OpSpec A021 or A024 may transport medical personnel as passengers accompanying a sick or injured person, but must meet the following requirements:
1) The operator may not advertise air ambulance or in-flight patient care services.
2) Any in-flight patient care equipment and medical personnel that accompany the passenger must be provided solely
for the patient’s comfort. If any medical care provider has determined that medical personnel are required for patient safety and/or life support,
the flight is an air ambulance operation.
NOTE: When a life-threatening situation exists, the PIC may exercise the PIC’s emergency authority in accordance with 14 CFR part
121.557; or §
conduct air ambulance operations. A PIC taking such action must subsequently report that action to the appropriate FSDO within 10 days. The inspector
investigating such a report should first determine whether information available to the operator and PIC at the time the flight began indicated that a
life-threatening emergency existed. Then the inspector should determine whether a suitably equipped air ambulance was not reasonably available within the
time acceptable to the requesting medical care provider.
3) OpSpec A021 HAA operations are more complex and are regulated to a much greater degree
(part 135 subpart L)
than general part
operations. (Refer to AC
the requirements for HAA operations.)
4) OpSpec A024 airplane air ambulance operations do not differ significantly from other types of airplane air carrier
operations. OpSpec A024 specifies operational requirements and grants the operator authorization for airplane air ambulance service.
4-921 FAA POLICY REGARDING COMPENSATION OR HIRE CONSIDERATIONS FOR CHARITABLE FLIGHTS OR LIFE FLIGHTS. Various organizations
and pilots are conducting flights that are characterized as “volunteer,” “charity,” or “humanitarian.” These flights are
referred to by numerous generic names, including “lifeline flights,” “life flights,” “mercy flights,” and “angel
flights.” These types of flights will be referred to as “life flights” in this section.
A. Purposes for Life Flights. The types of organizations and pilots involved with or conducting life flights vary
greatly. The most common purpose of life flights is to transport ill or injured persons who cannot financially afford commercial transport to appropriate
medical treatment facilities, or to transport blood or human organs. Other “compassionate flights” include transporting a child to visit with a
dying relative or transporting a dying patient to return to their city of birth.
B. FAA Policy. The FAA’s policy supports “truly humanitarian efforts” to provide life flights to needy
persons, including “compassionate flights.” This also includes flights involving the transfer of blood and human organs. Since Congress has
specifically provided for the tax deductibility of some costs of charitable acts, the FAA will not treat charitable deductions of such costs, standing alone,
as constituting “compensation or hire” as defined by §
61.113 or part
Inspectors should not treat the tax deductibility of costs as constituting “compensation or hire” when the flights are conducted for humanitarian purposes.
4-922 OVERVIEW OF HAA SERVICES. HAA operations have complex requirements not applicable to airplane air ambulance operations.
This paragraph provides a general overview of some of those requirements. AC
more extensive introductory material to HAA operations and their regulation.
A. OpSpec A021 Authorizations. A continuing trend of accidents during aeromedical operations resulted in the regulations
now embodied in part
135 subpart L.
Regulations include weather limitations for VFR flight, improvements in IFR operating limitations, added equipage requirements, pilot instrument qualifications
and demonstrations, the implementation of VFR planning and risk assessment procedures, medical personnel safety briefings and training, and, for operations
involving 10 or more HAA-designated helicopters, OCCs staffed by trained OCSs. These regulations must be met prior to issuance of OpSpec A021 (see
Volume 3, Chapter 1, Section 1 for
additional background information on OpSpecs). This OpSpec authorizes HAA service for hospital‑to-hospital patient transfer operations, scene response
operations, and other offsite ad hoc operations. This OpSpec grants latitude to an HAA operator for the following:
1) Unimproved Landing Sites. Selection and use.
2) Higher Minimums. HAA operations are subject to higher ceiling and visibility minimums in uncontrolled airspace than
those that are required for conventional part
3) Night Landings. Night landings at unimproved sites are permitted with adequate lighting, consistent with NVIS if
authorized and used, for the pilot to identify the landing site and surrounding hazards.
NOTE: “Adequate” lighting is lighting that allows a helicopter pilot to conduct a safe approach and landing during
conditions of darkness while avoiding terrain and obstacles. The source of this lighting may be on the helicopter or on the surface and includes the
possibility of automobile lights being used to illuminate the landing site. Pyrotechnic road hazard flares are not recommended for marking the touchdown area.
B. LFA. If an operator chooses to designate LFAs (LFAs are not required), it must establish and document a procedure for
the development of LFAs.
Pilots authorized by an operator to use reduced ceiling and visibility minimums must periodically demonstrate their familiarity with the features of the LFA.
Details are contained in AC
Volume 4, Chapter 5, Section 3,
paragraph 4-947. Each LFA must be listed in the operator’s OpSpec A021, Table 1.
C. OCC. After April 22, 2016, if the operator is required by regulation to have and maintain an OCC, the requirements of §
be met before OpSpec A021 may be issued. When an OCC is not required but an operator chooses to voluntarily implement similar capabilities or functions, the
operator’s applicable policies and procedures (and details of training in them) must be documented. This documentation must be accepted by the POI to be effective.
4-923 IFR AND VFR REQUIREMENTS. Operators of HAAs must comply with the following requirements for IFR and VFR.
A. IFR Operations. After April 22, 2017, §
that no certificate holder may use, nor may any person serve as a PIC of an HAA flight, unless that person meets the requirements of §
holds a helicopter instrument rating or an Airline Transport Pilot Certificate (ATPC) with a category and class rating for the aircraft that is not limited to VFR.
B. Evaluation. POIs of HAA operators conducting IFR operations should carefully evaluate the operator’s procedures,
training and qualification program, and the operating environment before granting the operator the authority to conduct single-pilot IFR operations with an
autopilot (refer to §§
Such evaluation applies especially with respect to point in space (PinS) approaches, IMC-to-visual transitions following a PinS approach, and visual-to-IFR
transitions between the takeoff point and the initial departure fix before granting the operator the authority to conduct single-pilot IFR operations with
an autopilot. (Refer to
§§ 135.611 and
C. VFR Operations. When conducting VFR flight, the operator must comply with the weather minimums specified in §
as authorized by OpSpec A021. Operator requests for lower-than-standard VFR minimums must be coordinated with AFS-200 through the appropriate RFSD.
RESERVED. Paragraphs 4-924 through 4-930.
