AASSEP-07
Manufacturers and national programmes providing power driven hydraulic ground servicing equipment used to cross-service NATO aircraft
AASSEP-07 is the NATO Allied Publication standardising power driven hydraulic ground servicing equipment so nations can cross-service each other's aircraft, under STANAG 3510.
AASSEP-07 is a NATO Allied Aircraft Servicing and Standard Equipment Publication: a technical document, not itself the agreement that gives it force. Its own aim clause states the purpose plainly: "to standardize the essential characteristics of power driven hydraulic servicing equipment to facilitate cross-servicing of aircraft." Cross-servicing is the point of the whole publication - a ground crew from one NATO nation properly servicing an aircraft that belongs to another, using equipment and fluid that are compatible rather than nationally invented. Nations record their agreement to use the publication in STANAG 3510: "The agreement of nations to use this publication is recorded in STANAG 3510." AASSEP-07 is Edition A, Version 1, promulgated in November 2014 and effective on receipt; it names no earlier edition it supersedes.
The publication sets equipment characteristics, not procedures. Its normative chapter covers four things: the power driven hydraulic servicing equipment itself (what it must be capable of, in terms of control and output range), the supply equipment that feeds it, the hoses that connect it to an aircraft, and the connectors used at the aircraft end. It requires the fluid delivered to the aircraft to meet a stated cleanliness standard, set out in AFLP-4714 and STANAG 3748, and it requires connectors built to ISO 3174. It also requires servicing equipment to be clearly marked to show which hydraulic fluid it uses - a labelling requirement aimed squarely at stopping an allied ground crew using the wrong fluid on an unfamiliar aircraft. Two annexes record, nation by nation, the connector part numbers and fluid types currently fielded; these are a reference for recognising equipment on the ground, not a specification a new design is built against.
AASSEP-07 does not name a commercial supplier directly. What it addresses is the equipment and the people who use it: ground crews performing cross-servicing, and by extension the manufacturers and national programmes that build or procure the equipment those crews rely on. A supplier meets AASSEP-07 because a national or NATO procurement programme specifies ground hydraulic servicing equipment built to it, not because the publication names suppliers as its audience.
Cross-servicing only works if the equipment lines up. A ground crew servicing an aircraft that belongs to a different nation needs a connector that fits, a hose that reaches, and fluid that meets the same cleanliness standard the aircraft's own equipment expects - and needs to be able to tell, at a glance, which fluid a piece of equipment is loaded with. AASSEP-07 exists to make those things predictable across NATO nations rather than something discovered, awkwardly, on the ramp. Annex A and Annex B show this is not yet a single design: connector part numbers and fluid types already vary by nation, which is exactly the gap a common standard is meant to close over time.
A manufacturer of ground hydraulic servicing equipment builds to the operating characteristics AASSEP-07 sets out in clause 2.1.1, sources or handles fluid that meets the cleanliness standard in AFLP-4714 and STANAG 3748 (clause 2.1.2), fits hoses and connectors built to ISO 3174 (clauses 2.1.3 and 2.1.4), and marks the equipment to show which fluid it uses (clause 2.2). None of this is assessed by a certification body: AASSEP-07 names no accredited body, no government-surveillance regime and no self-declaration mechanism. A national or NATO procurement authority evaluates equipment against the manufacturer's own technical data when it buys it.
AASSEP-07 is unclassified and free of charge. NATO's Standardization Document Database lists the current edition; we do not host a copy or sell it.
Building ground hydraulic servicing equipment to AASSEP-07's characteristics, sourcing fluid that meets STANAG 3748 and AFLP-4714, and fitting ISO 3174 connectors is mechanical and engineering work, carried out on the equipment itself, not in a compliance platform. What ComplyTrain supports is the paperwork and evidence trail around that work: a controlled procedure describing how staff check servicing equipment against AASSEP-07's characteristics before it is fielded, training records for ground crew on correct fluid identification and marking checks, and a record of which equipment and fluid standard a given contract or national programme requires.
ComplyTrain does not test a servicing rig's output, certify a connector to ISO 3174, or verify fluid cleanliness in a laboratory - that stays engineering and test work. Which equipment characteristics apply to a given procurement is set by the contract and the customer's quality clause.

Thank you. Your list is on its way to your inbox, and we will come back to you on what working with these standards in ComplyTrain involves, usually within one business day.
AASSEP-07 does not bind a supplier directly. Nations record their agreement to use it in STANAG 3510, and a supplier meets it only when a contract or a national procurement programme requires hydraulic ground servicing equipment built to this publication.
No. The publication names no certification body, government-surveillance regime or self-declaration scheme. It sets equipment characteristics, and a procuring authority evaluates equipment against a manufacturer's own technical data when it buys it.
Characteristics for power driven hydraulic ground servicing equipment: what the equipment and its supply must be capable of, the fluid cleanliness standard it must deliver, hose and connector requirements built to ISO 3174, and a requirement to mark equipment with the fluid it uses.
STANAG 3510 is the agreement NATO nations ratify; the Letter of Promulgation states that "the agreement of nations to use this publication is recorded in STANAG 3510." AASSEP-07 is the technical publication that agreement covers.
Because cross-servicing puts an unfamiliar ground crew in front of unfamiliar equipment. Clause 2.2 requires servicing equipment to be "clearly marked to show which hydraulic fluid is to be used," so a crew servicing another nation's aircraft can identify the correct fluid without guessing.
One system for the whole compliance programme. Start with the module you need most.
Collect information the same way every time, and decide in advance what happens next.
Know whether your controls are operating, not just whether a policy says they exist.
Turn the compliance work you already know about into a plan with owners, dependencies and dates.
Know what you can offer, and hold the evidence behind every configuration you offer it in.
