AASSEP-06
Manufacturers building the aircraft-side or ground-equipment-side half of the AASSEP-06 connector
AASSEP-06 sets the dimensions, circuit and electrical tolerances of the connector used to start an aircraft engine with low pressure air from ground equipment, so any NATO nation's compliant kit can plug in.
AASSEP-06, Low Pressure Air and Associated Electrical Connections for Aircraft Engine Starting, is a short NATO Allied Technical Publication. It standardises the electrical connector used when an aircraft is started with low pressure air from ground equipment: the connector's physical form and where it sits on the aircraft, the clearance space a technician needs to connect and disconnect it, its circuit arrangement, and the electrical tolerances the circuit has to hold. It is covered by STANAG 3372, the NATO agreement by which nations record their commitment to use it. Edition A, version 1 was promulgated in November 2014.
The point of an interface standard like this one is ordinary but easy to miss: it exists so that a ground crew from one NATO nation can start an aircraft belonging to another using their own equipment, because both sides built to the same connector. AASSEP-06 does not name an audience in so many words, its requirement clauses simply fall on whoever builds each half of the connector: the airborne connector fitted to the aircraft structure, and the ground cable connector on the trolley or cart that supplies the starting air. Get the interface wrong on either side and the two halves will not mate, which is exactly the outcome a shared standard is written to prevent.
AASSEP-06 does not bind a supplier by existing. Its own promulgation letter records that nations' agreement to use it sits in STANAG 3372, and the publication becomes effective for a nation once that agreement is in place. From there it reaches an individual manufacturer the way most NATO technical publications do: through a tender or a contract that calls up AASSEP-06 or the STANAG that covers it, not automatically. Because it governs the physical and electrical shape of a connector, it is a design-stage document. Getting the interface right before a connector design is finalised is straightforward; correcting it once aircraft or ground carts are already built is not.
AASSEP-06 covers four things, in two short chapters. Where electrical control from the aircraft to the ground equipment is needed, the airborne connector has to conform to the dimensions the document sets out in its first annex, and the ground equipment's connector has to be compatible with it, with the ground cable connector itself being of the quick-disconnect type. A minimum clearance space around the aircraft's connector, enough to connect and disconnect it safely, is set out in a second annex. The circuit itself has a fixed arrangement across the connector's contacts, including one contact whose function differs between UK and US aircraft wiring practice. And the electrical circuit is bound by three standing tolerances: a limit on the voltage drop along each current-carrying connection, a limit on the temperature rise of any contact, and a permitted range for how far the electrical connector may sit from the centre line of the air connection that ISO 2026 defines. This page does not reproduce the dimensions, clearances or tolerance figures themselves, or the connector's pin assignments: those are exactly what a connector builder buys the document for, and they belong in the document's own tables, not paraphrased here.
AASSEP-06 is the electrical half of a larger interface. Its own related-documents clause names ISO 2026, the civil standard covering the corresponding air connection, and the electrical specification positions this connector relative to that standard's centre line. A supplier building the full interface needs both documents, not AASSEP-06 alone.
AASSEP-06 names no certification, audit or inspection mechanism, and no body is described anywhere in the text as checking a manufacturer's conformance against it. Meeting the standard is a matter of building a connector to the dimensions, clearances and electrical tolerances it and its annexes set out, and holding the design and verification records that show that was done. There is no accredited certification body, government surveillance arrangement or notified-body assessment attached to this document.
AASSEP-06 describes engineering work, not paperwork: designing and verifying a connector against a fixed physical and electrical interface happens in a mechanical and electrical engineering function, not in software. What a supplier needs to be able to show is which contract or programme calls up AASSEP-06, that the connector design was checked against it, and that the resulting drawings, test records and any approved deviations can be produced on request. ComplyTrain holds that design and verification evidence as controlled documents, tracks which product configurations or contracts declare conformance to AASSEP-06, and gives an auditor a trail from a contract requirement back to the evidence that a specific connector was built and checked against it.
ComplyTrain does not design the connector, take the dimensional or electrical measurements itself, or decide whether a deviation from the standard is acceptable. That stays with the engineering and test function responsible for the hardware.
Which tier of ground-support standards applies to a given contract, and whether AASSEP-06 is one of them, is set by the contract and the customer's quality clause.

Not by itself. AASSEP-06 binds a nation once that nation is party to STANAG 3372, the NATO agreement that records nations' commitment to use it, and it reaches an individual supplier through a tender or contract rather than automatically. Whether it applies to a specific programme is a matter for the contract and the customer's quality clause.
The electrical connector used to start an aircraft engine with low pressure air supplied by ground equipment: the connector's physical form, its mounting clearance, its circuit arrangement, and the electrical tolerances the circuit must hold. It does not cover the air-side connection itself, which is the subject of ISO 2026.
ISO 2026 covers the corresponding pneumatic connection for starting an aircraft engine with air. AASSEP-06's electrical specification positions its own connector relative to the centre line ISO 2026 defines, so the two documents describe adjoining parts of the same interface rather than overlapping.
No. The document names no certification, audit or inspection scheme. Meeting it is a matter of building a connector to its dimensional, clearance and electrical requirements and holding the evidence that this was done, not something a certification body assesses.
STANAG 3372 is the NATO Standardization Agreement that covers AASSEP-06. It is the record of nations' agreement to use this publication, which is how AASSEP-06 acquires force at national level.
