Inspection regulations
In case of security relevant damages the fire extinguisher has to be scrapped immediately.
If the pressure is reduced the fire extinguisher has to be basically overhauled immediately.
(1) Pre-flight inspection
Check the pressure gauge. At room temperature the indicator must be in the green section.
The seal wire on the safeguard lever must not be damaged.
(2) Periodical check
The inspection should be carried out every 2 years, or in shorter intervals, depending on
internal regulations.
  Integrity of wire seal visual inspection
  Condition of extinguisher, mounting bracket and visual inspection
fastening strap
  Legibility of label visual inspection
  Container pressure / gauge visual inspection
At room temperature the pointer must be in the
green section of the dial.
  Weight control / scale
Permissible deviation: 2% of fill capacity / year, but not more than 10% of fill capacity
(3) Characteristics after 5 years
After expiration of 5 years, in case of filling / refilling, the container of the fire extinguisher has
to be inspected inside. Should defects be detected, the extinguisher has to be hydrostatically
pressure tested.
(4) Basic overhaul
Container hydrostatic pressure test
All fire extinguishers, listed in that maintenance procedure instruction, must be hydrostatically
pressure tested at regular 10 year intervals. The 10 year period starts with the date of
production of the extinguisher (see label on back). Should defects be detected at a regular
inspection, this pressure test must be performed earlier. These tests shall only be carried out
by an authorized aviation equipment inspector, well adverted with the safety standards
applicable to this test. Furthermore, also required is an adequate room and the necessary
test equipment. After the hydrostatic pressure test the cylinder has to be desiccated inside.
If the second hydrostatic pressure test is due, the manufacturer recommends to replace the
extinguisher!

Disassembly and cleaning
 Empty the extinguisher (observe environmental protection regulations concerning HALON
1211).
  Unscrew valve (50*, 50A*) with open-end wrench size 17.
  Unscrew the siphon tube (220*, 220A*).
 Visually inspect valve and container threads and O-ring seat for damage.
Press operation lever and check mobility of valve spindle.
  Visually inspect inside of container for corrosion.
 Screw siphon tube back up to the limit stop with a torque of 20 Nm.
 Screw valve with new O-ring (20*) back on to the container.
(Apply a light layer of acid free vaseline to thread and O-ring).
Torque: 30 Nm
 Clean container. Check label, mounting bracket and fastening strap for damage.

Filling (see illustration 2)
The fire extinguisher shall only be refilled by a maintenance service shop with an approval to
“Commission Regulation (EC) No 1702/2003”.
When filling HALON extinguishers the filling station must observe the following instructions:
(1) Determining net weight:
After assembly the empty extinguisher must be placed on a scale to determine the
weight. This net weight must be entered in the check note.
(2) Refilling:
Place the extinguisher on a scale and connect it to the fill station. During the filling process
the release lever of the extinguisher must be held down with a clamp. The weight of this
clamp must be taken into consideration in the weighing process.
The extinguishing agent is filled according to weight. Care must be taken to observe the
permissible fill tolerances.
Portable Fire Extinguishers:
HAL 1 1 Kg HALON 1211 (+0 -0.02 kg)
HAL 1,2 1.2 Kg HALON 1211 (+0 -0.02 kg)
HAL 2,5 2.5 Kg HALON 1211 (+0 -0.02 kg)
After the filling the extinguisher must be pressurized with gaseous nitrogen (99.0 to 99.8
degree of purity, dew point -40°C, (-40°F)). The pressurization for HAL 1, HAL 1,2 and
HAL 2,5 should be according to temperature-pressure curves T565*.
The nominal fill pressure at +15°C is 11 bar (mark in green section of gauge dial). Than
move the closed extinguisher horizontally back and forth to mix HALON and nitrogen
together. In this process the container pressure drops. Depressurize the extinguisher to
the specified pressure. Remove the clamp from container release lever. Secure release
lever. The fill line can than be depressurized and also closed.

(3) Determination of total weight:
After the fill process is completed and the extinguisher disconnected from the fill line, the
extinguisher must be placed back on the scale again to determine the total weight. This
weight must be entered in the inspection record card and on the extinguisher check note
(when weighing the extinguisher, the weight of seal, seal wire and the approval label must
be included).
Seal the extinguisher (Seal wire tensile strength 40 N).
(4) Acceptance of filled extinguisher:
Acceptance and clearance of the extinguisher must be made by authorized staff.
Acceptance test:
  General visual inspection of the extinguisher
  Checking operating pressure (see page 5 technical data)
  Tightness control. Checking the unit after 3 weeks in storage
