Introduction
This part of ISO 6966 specifies the safety requirements to be taken into account by manufacturers for
the design of aircraft ground support equipment. It identifies the various concerns to be taken into
consideration to ensure ground equipment safety for operators and aircraft.
Throughout this International Standard, the minimum essential criteria are identified by use of the
keyword “shall”. Recommended criteria are identified by use of the key word “should” and, while not
mandatory, are considered to be of primary importance in providing safe, economical, and usable
aircraft ground support equipment. Deviation from recommended criteria should only occur after
careful consideration and thorough service evaluation have shown alternate methods to provide an
equivalent level of safety.
The requirements of this International Standard are expressed in the applicable SI units, with
approximate inch-pound units conversion between brackets for convenience in those countries using
that system. Where it is deemed necessary to use exact values, the SI unit ones are to be used.

Part 2:
Safety requirements
1 Scope
This part of ISO 6966 specifies the minimum design requirements applicable to all aircraft ground
support equipment (GSE), as defined in 3.1 hereafter, in order to ensure
a) safety of staff operating or maintaining the equipment or in its vicinity, and
b) protection of aircraft against interference or damage.
An informative list of the most commonly used pieces of ground equipment is provided in Annex A
hereafter. Nevertheless, the requirements of this part of ISO 6966 apply to any piece of aircraft ground
support equipment, as defined, used on airports.
This part of ISO 6966 does not intend to provide all the design requirements applicable for aircraft
ground support equipment. Other requirements apply, and can be found in separate International
Standards:
— ISO 6966-1 specifies the general, other than safety-related, requirements applicable to all aircraft
ground support equipment;
— ISO 4116 specifies the additional requirements applicable for conveying surfaces of those pieces of
aircraft ground support equipment intended for handling and loading of baggage and cargo unit
load devices;
— specific International Standards, listed in the Bibliography, define the functional and performance
requirements for certain types of aircraft ground support equipment.
In most countries, standing Government Health and Safety laws and regulations apply to machinery,
implicitly or explicitly, including aircraft ground support equipment. Nothing in this part of ISO 6966,
however, shall be deemed or otherwise used to supersede any locally applicable law or regulation, unless
a specific exemption has been obtained for this purpose from the appropriate Authority.
This part of ISO 6966 does not apply to automotive vehicles or parts thereof approved for public vehicles,
when used on aircraft ground support equipment for the purpose for which they are designed.

4 Requirements
4.1 General
4.1.1 Considerable importance is attached to having aircraft ground support equipment into which
the essential safety aspects have been incorporated as part of the basic design (design to safety). It is
particularly necessary when designing aircraft GSE to take into account the adverse conditions which
frequently prevail in airport ramp areas, e.g. congested vehicle movement, exposure to weather, night
operation, noise from aircraft and other vehicles, and difficult communications.
4.1.2 Design to safety should be based on a specific comprehensive risk assessment for each type of
aircraft GSE, to be conducted by the manufacturer in accordance with ISO 14121-1. The retained design
should be commensurate with the results of the risk assessment, as well as take into account, if applicable,
each area of potential concern listed hereafter.
4.1.3 Design should aim at providing intrinsically safe equipment, i.e. one where potentially unsafe
occurrences are prevented by basic design features such as equipment and components geometry, layout,
or mode of operation, minimizing inasmuch as feasible the necessity to use additive safety devices or
circuits. Where such additional devices or circuits dedicated to safety purposes cannot be avoided, risk
assessment shall include an evaluation of any potential drawbacks or unforeseen additional hazards
resulting from this addition.
4.1.4 All equipment or any component thereof, the failure of which could be hazardous, shall be
designed to be fail-safe, or, where impractical, duplicated. In the event of duplication, each of the duplicated
components shall separately be capable of safely performing its function in the event of its alternate’s
failure.
4.1.5 The contents of this part of ISO 6966 were determined taking into account generally recognized
assumptions as to the following:
a) the normally intended use of aircraft ground support equipment, when used on the ramp of
international civil airports in order to handle, service, or maintain civil transport aircraft;
b) the foreseeable risks of equipment misuse evidenced by operating experience;
c) the environmental (surface, slope, weather, lighting, operating rules, staff qualification, etc.)
conditions prevailing on the ramp area of the majority of international civil airports.
Manufacturers of aircraft ground support equipment should define in the relevant documentation (see
Clause 6) the specifically intended conditions of use and environment for each equipment, and purchasers
systematically review their own specific conditions of use and environment in order to determine

ISO 6966-2:2014(E)
whether those stated are adequate, or negotiate with the manufacturer appropriate modifications to
ensure they are.
NOTE For intended operation in Europe, additional EU Machinery Directive (see Reference [31]) requirements
also legally apply. They can be met by complying with the requirements of European standards EN 1915-1,
EN 1915-2, EN 1915-3, and EN 1915-4.
