5. BACKGROUND. Transportation by aircraft of sick or injured persons may have originated during World War I when wounded were transported from battle fronts to field hospitals in an open cockpit biplane. Since that time, the transportation of patients needing medical attention has burgeoned into a significant industry operating modern aircraft equipped with state-of-the-art medical equipment carrying thousands of patients each year. The introduction of civil airplanes dedicated exclusively to EMS began about 1973. The operators of these aircraft can provide patient care while en route from city to city or from remote sites to urgent care facilities. Many airplane/air ambulance ii

n/19/90 AC 135-15 flights are conducted with small, nondedicated aircraft operated by FAR Part 135 on-demand air carriers. There is also a contingent of private and public service aircraft operators conducting air ambulance flights. This AC provides guidance to operators conducting or planning EMS/A operations.

n/19/90 CHAPTER 1. CERTIFICATION AC 135-15 1 GENERAL. Aircraft operators desiring to commence Air Akmlance service as a FAR Part 135 air carrier who do not hold a FAR Part 135 air carrier certificate should refer to AC 120-49, Certification of Air Carriers, dated November 23, 1988, for methods and procedures to follow in the certification process.

The Flight Standards District Office (FSDO) located in the area where the applicant desires to locate its principal business office will assist the applicant in becoming certificated. This chapter refers to added steps that may be required of an EMS/A operator to obtain a FAR Part 135 certificate.

NOTE: For those operators presently conducting operations under FAR Part 135, new or revised operations specifications may be required prior to initiating EMS/A operations.

a. Inspections. Inspection at the principal base of operations will include items such as operations and maintenance facilities, equipment (including installation of special/medical equipment), lease agreements, and contract maintenance records.

Before issuance of operations specifications authorizing FAR Part 135 operations, FSDO personnel will perform the following inspections to ensure that the applicant meets requirements for FAR Part 135 air carrier certification:

(1) Manuals to assure they contain information required by FAR Section 135.23.

(2) Recordkeeping system.

(3) Aircraft used in air transportation service.

NOTE: Lease agreements are considered proprietary documents and will be handled with confidentiality by FAA personnel.

(4) Each certificate holder is responsible for the airworthiness of its aircraft (FAR Section 135.413). Operator and/or contract maintenance facilities may be inspected for compliance with the appropriate FAR. This particular inspection will be accomplished to determine adequacy of tools, spare parts, special tools, and that properly trained personnel are available.

Chap 1 Par 1

AC 135-15 u/19/90 b ident& Additional Equipment/General. The applicant should in their initial application, any specialized equipment that may be used in EMS operations. The equipment should be installed in the aircraft in an acceptable method (using data approved by the aircraft manufacturer, an EMS equipment manufacturer, or the FAA Administrator), The FAA may approve add-on equipment installation after evidence of airborne test results are submitted from the aircraft operator, the Department of Transportation (DOT), Department of Defense, or an independent testing organization. Any equipment installed aboard the aircraft should comply with the data in AC 43.1302A, Chapter 1, paragraph 2(d) and 3, and Chapter 12, paragraph 243(a), and withstand the following static loads in accordance with AC 43.1301A:

(1) 9.OG forward, 6.6G downward, and 3.OG upward, and 1.5G sideward; and

(2) tie-down, 13.5G forward, 9.9G downward,

4.5G upward, 2.25G sideward.

(3) SuPplemental Type Certificate (STC) or Field Approval. All items of additional equipment must be installed in accordaxe with the applicable FAR. The installation of additional equipment may require a STC or field approval by an airworthiness aviation safety inspector. It should be noted that the requirements for field approval are the same as for a STC.

If the certificate holder is unsure of the requirements on the proposed equipment, they should contact the PM1 before installation is initiated.

(4) Maintenance Fliqht Test. Certificate holder should ensure that the installation of all additional equipment is compatible with all previously installed aircraft systems.

Aircraft navigation and communication equipment may have to be recalibrated after installation of any additional medical equipment. Before returning the aircraft to service after the installation of additional equipment, flight tests may have to be accomplished to determine if there is radio frequency/ electromagnetic interference (RFI/EMI) with any navigation, communication, or flight control systems. The flight tests should be accomplished in visual meteorological conditions.

Tests should include all installed equipment as well as all items of carry-on medical equipment intended to be used for patient transport. Results of the flight tests verifying acceptability should be entered into the appropriate permanent records of the aircraft.

Chap 1 Par 1

u/19/90 AC 135-15 NOTE: Medical monitors may also be affected by the aircraft's electronic equipment; therefore, the medical monitors should be checked for accuracy by medical personnel before use with & patient.

To ensure a safe and satisfactory completion of transportation and to coordinate with ground transportation service when necessary for the patient.

(2) Medical Oxyqen System. A medical oxygen system including bottles, lines, gauges, regulators, and other system components which has been installed by approved data on an aircraft becomes an *fappliance.tt If a single servicing port is installed in accordance with AC 27-1, as revised, Certification of Normal Category Rotorcraft, or AC 2902A, as revised, Certification of Transport Category Rotorcraft, the system may be serviced by any person trained by the certificate holder. An oxygen bottle installed in a rack in the cabin area having its own regulator, hose, and mask feeding directly to the patient may be removed and serviced by any person trained by the certificate holder. If servicing is accomplished by removing and replacing bottles or by disconnecting lines, regardless of the type fitting, it must be accomplished by an appropriately certified mechanic or repairman.

NOTE: Information concerning equipment installation in the referenced advisory circulars are applicable to airplanes and helicopters.

(3) Supplemental Lishtina Systems. Some aircraft may require additional interior lighting since standard aircraft lighting may not be sufficient for adequate patient care. An emergency lighting system with a self-contained battery pack may be incorporated to allow for continued patient care and for emergency egress from the aircraft in the event of a primary electrical failure. A means to shield the cockpit from light in the patient area should be provided for night operations.

(4) EMS Electrical Power. All wiring, electrical components, and installation procedures must conform to the requirements of FAR Parts 23 or 25. An electrical load analysis must be performed to preclude an overload on the aircraft generating system. The system should be designed to give the pilot a fast means of shedding electrical load in an emergency situation.

(5) Motor-driven Vacuum/Air Pumps. Motors and/or pumps must be installed in accordance with FAR Parts 23 or 25.

Any motor-driven device should be installed in a way to preclude contact with any flammable fluid, gas, or foreign materials that may cause heat buildup and possibly fire. Aircraft should be flight-tested with electrical motors running to check for RFI/EMIm

(6) Incubators, Incubators, balloon pumps, or other large carry-on medical equipment must be restrained in an appropriate manner to the following ultimate load factors:

(i) 3.OG upward, 6.6G downward: and

(ii) 9.OG forward, 1.5G sideward.

NOTE: If pull test data are not provided by the equipment manufacturer to verify that specific equipment can withstand the above loads, the certificate holder must demonstrate the above loads on each specific piece of equipment, device.

or use an approved restraining Aircraft cargo straps or safety belts provide a satisfactory restraint in many4nstances. Also, mechanical (metallic) fasteners may be used for attachment.

NOTE: The incubator lid latches'should withstand appropriate loads (approximately 15 pounds and any significant lid load).

The operator should ensure the unit has minimum movement when secured if straps or belts are used. If the incubator includes features requiring electrical power, operation should be evaluated to assure there is no interference with the instruments and equipment that are required by the FAA airworthiness certificate for safe operation of the aircraft.
