Overview

EN 12312-19:2005+A1:2009 is a CEN standard that defines safety, functional and limited performance requirements for aircraft ground support equipment (GSE) specifically covering aircraft jacks, axle jacks and hydraulic tail stanchions. Its purpose is to minimise hazards during commissioning, operation and maintenance when equipment is used according to the manufacturer’s instructions. The Part 19 requirements are intended for all types of aircraft jacks and for axle jacks and tail stanchions designed for specific aircraft jacking points. Noise, vibration and aircraft recovery equipment are outside its scope.

Key topics and technical requirements

• Scope of application: applies to aircraft jacks, axle jacks and hydraulic tail stanchions (not to recovery equipment or items manufactured before publication).
• Conformance & linked standards: intended to be used with EN 1915-1, EN 1915-2, EN 1915-3 and EN 1915-4, and follows general safety principles in EN ISO 12100.
• Stability and strength: calculations per EN 1915-2 to avoid crushing and instability risks.
• Hydraulic safety:
  • Pressure relief valves must not be located between the ram and control device and shall be set to no more than 125% of rated load.
  • Tail stanchions must allow tail upward movement without lifting the foot and include a safety valve and a ground-visible pressure gauge.
• Control & lowering: operators must be able to control or stop lowering at any load (e.g., finely controllable valve). Manual forces and measurement methods are specified in Annex C.
• Multi-jack operation:
  • A failure on one drive must stop all jacks.
  • Movement monitoring required; automatic correction for height differences up to 100 mm, and immediate stop if >100 mm.
  • Manual lowering of grouped jacks is not permitted.
• Maneuverability & ergonomic features:
  • Jacks and tail stanchions: steering and permanent access for adjustment; emergency stops at each operator panel (EN ISO 13850 requirements).
  • Axle jacks: design for accurate positioning, rigid towing devices, grab handles and safe control designs to prevent pinching/cutting.
• Marking & documentation: metal nameplate, rated load, aircraft type restrictions, pressure/force tables (for stanchions) and comprehensive operating/maintenance instructions including safe handling, limitations and operator training.

Practical applications & users

• Who uses it: GSE manufacturers, airlines, ground handling agents, maintenance organizations, safety engineers and regulatory bodies.
• Practical uses: design and certification of jacks and stanchions, procurement specifications, safe operating procedures, equipment inspection and acceptance testing, and staff training on GSE safety and handling.

Related standards

• EN 1915-1, EN 1915-2, EN 1915-3, EN 1915-4 (GSE general requirements; vibration/noise methods)

Introduction This document specifies health and safety requirements, as well as some functional and performance requirements for aircraft jacks, axle jacks and hydraulic tail stanchions intended to be used for servicing and handling of all aircraft types commonly in service in civil air transport. The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical, and practical aircraft jacks, axle jacks and tail stanchions. Deviations from the recommended criteria should occur only after careful consideration, extensive testing, risk assessment and in service evaluation have shown alternative methods or conditions to be satisfactory. This document is a Type C standard as stated in !EN ISO 12100". The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this Type C standard are different from those which are stated in Type A or B standards, the provisions of this Type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this Type C standard.
