INTRODUCTION
DESCRIPTION
Mustang inflatable life preservers are items of primary survival equipment, and as such,
every precaution shall be taken to assure proper storage, maintenance, and handling. The
life of the wearer may well depend on the condition of the life preserver and the security
of its attachments and equipment. This publication provides the information required to
inspect, test, and maintain the inflatable life preserver model MD1127. This model has been
approved by the Federal Aviation Administration (FAA) as Type I Life Preservers according to
the Technical Standard Order TSO-C13f.
A. General
Mustang Survival is pleased to present an FAA approved inflatable life preserver, the
MD1127. This product is designed with sufficient buoyancy to turn an unconscious
person face upwards within five seconds of immersion. Fully inflated, the life preservers
provides a minimum effective buoyant force of 35 lbs. The MD1127 is universal in
size and is designed to fit most adults comfortably. This can be worn over bulky
outer clothing, and has adjustable nylon waist belts which secure an easy-to-wear
position allowing for maximum freedom of movement. Each life preserver is equipped
with a small rescue light, which is water activated and may be used as a beacon for
emergency rescue situations.
WARNING:
CONSTANT WEAR USE ONLY TO BE DONNED PRIOR TO EACH FLIGHT
Note: The conditions and tests required for TSO approval of these articles are minimum
performance standards. It is the responsibility of those desiring to install the articles either
on, or within, a specific type or class of aircraft to determine that the aircraft installation
conditions are within the TSO standards; the articles may be installed only if further
evaluation by the applicant documents an acceptable installation, and is approved by the
Administrator.
The life preserver is inflated by using a carbon dioxide gas inflation system. It is a
common characteristic that all inflatable life preservers will gradually permeate CO2
gas through their cell material with time, and a softening of the cell will be observed
over extended periods. In the MD1127 this is over come by providing an oral inflation
system to top up the pressure in the cell. The oral inflation system may also provide
added pressure to the cell in cold temperature conditions, since under these conditions
the CO2 gas will not expand as greatly as in warmer temperatures. Finally, in the event
that the CO2 inflation system fails to operate, the oral inflation system may be used as
a backup system to fully inflate the life preserver.

B. The MD1127 Life preserver
1. Design and Construction
The MD1127 has easy-to-use, Velcro®, hook and loop fasteners on each
side of the front cover. This allows the life preserver to be opened when
inflated, and easily folded when deflated. When inflating, the Velcro®
fasteners burst open allowing the inflation cell to expand out of the cell
enclosure.
The MD1127 incorporates a dual chamber inflatable cell, which is
separated by an internal floating baffle. The floating baffle allows either
chamber to fully inflate the life preserver. The life preserver is styled as a
protective collar fitted around the neck and front chest. The protective collar
is constructed from a highly durable 6 oz. Nomex Omniweave. The outer
shell of the MD1127 is not integral with the inflation cell, but acts as a cell
enclosure by opening the Velcro® seals; when deflated, the inflation cell is
folded and placed back into the cell enclosure as shown in Figure 4.
Figure 1: Deflating the buoyancy cell
The MD1127 includes a small carry pouch attached to the waist belt, and
two small pockets located on each of the insides of the front cover. A safety
whistle is supplied with the life preserver, attached to the bottom right section
of the bladder. A sea light is attached to the left side of the bladder.
a) Starting from the end farthest from the oral valve, tightly roll
up the life preserver.
2. Inflation System
The MD1127 dual chamber inflatable cell design incorporates a primary
inflation cell accessed from a CO2 inflation system and an oral inflation
system, along with a secondary cell accessed from its own oral inflation
system. In case the primary inflation cell has been punctured, or fails to
inflate, the life preserver may be inflated orally by the secondary inflation
cell. The oral inflation systems consist of an oral tube and oral valve. The oral
valve is normally closed, and is opened by depressing the mouthpiece when
inflating or deflating.
b) Depress the oral valve to release the trapped air.
5. Belt
A durable nylon waist belt is attached to the life preserver. This belt is
fastened and fitted using a quick-release buckle and waist belt adjuster.
To tighten the belt, pull the extra webbing from the waist belt adjuster, as
shown in Figure 5. After adjusting the fit, the excess webbing is led through
a belt loop to keep it out of the way.
3. Inflation Cell
The polyurethane coated nylon dual chamber inflation cell is not integral with
the outer shell of the life preserver, but is connected to the outer shell only
by the inflation system. The dual chamber cell is in the form of an inflatable
head support collar, which fits around the neck and chest. The primary
chamber of the cell is located on the outer front side of the inflation cell,
while the secondary cell is located on the inner side of the inflation cell.
The dual chamber cell is fully inflated with one 35 gram cylinder of
compressed CO2 gas.
6. Markings
The life preserver is marked with indelible stencil and all markings appear
in both English and French. The life preserver is marked with donning
instructions, which are located on the left back cover. The donning instruc-
tions are printed clearly enough to be read even in dimly lit surroundings.

7. Package
A bright yellow polyurethane coated nylon package is provided for
storage purposes. The package is closed by a Velcro® patch placed on its
cover flap. This allows the package to be opened quickly in the event of
an emergency.
b) Insert second arm into other side of life preser ver.
OPERATING INSTRUCTIONS
A. The Buoyancy Cell
As with any type of personal protective apparel, your Mustang inflatable
will perform most effectively, and its life will be extended, if it is properly
cared for. Periodically, and prior to each use, visually inspect the fabric and
the buoyancy cell for signs of damage. Periodically test the buoyancy cell
to make certain that it does not leak by following the testing procedures
outlined in this manual. Once a month, inflate the cell by mouth until it is
firm and leave overnight. If it is airtight, the cell should still be inflated the
next day.
c) Fasten waist belt.
Also check that all seams and joints are securely sewn and that the
fabric, straps and hardware are still serviceable. At the same time, test the
oral inflation valve for leakage by immersing the valve in a glass of water.
Bubbles in the water may indicate a faulty valve. If your Mustang inflatable is
damaged, replace it immediately.
d) Pull inflation handle sharply downwards.
1. Deflating the Buoyancy Cell
To fully deflate the buoyancy cell, squeeze and roll up the cell gently, then
depress the top of the oral valve until all the air or gas is removed, as shown
in Figure 2. For the MD1127, the deflated buoyancy cell is then to be
returned to its storage position within the cell enclosure (see Figure 4).
e) Tighten waist belt adjuster.
Figure 3: Donning and Operating Instructions
2. Inflating the Buoyancy Cell
Manual inflation
Inflation with CO2 gas is accomplished quickly and simply by pulling down
sharply on the beaded pull cord on the right hand side of the life preserver.
This action releases gas into the buoyancy cell, which then fully inflates with
in 5 seconds.
a) Insert first arm between back strap and front cover.

Oral Inflation
In the event that the CO2 gas cylinder fails to inflate the buoyancy cell, or if
the cell needs to be topped up during use, your inflatable life preserver can
be inflated by mouth through the inflation tube. To inflate by mouth, depress
the mouthpiece and blow into the tube until the cell is fully inflated.
3. Fit Adjustments
b) Fold each side of the inflation cell so that the V elcro® tape along the
enclosure flaps is exposed.
Immediately after the buoyancy cell is fully inflated, adjust the waist belt by
pulling or releasing the waist strap until the life preserver fits comfortably,
without riding up (see Figure 5).
CAUTION: Under no circumstances should a partially inflated
buoyancy cell be re-inflated by discharging the CO2 gas
cylinder because it may overfill and rupture the cell.
c) Fold the enclosure flaps over the inflation cell so that the V elcro® tape is
completely sealed.
B. Donning Instructions
The following steps outline the procedures for donning the MD1127 life
preserver, see Figure (3a - 3e) for illustrations of each step.
Proceed as follows:
C. Folding Procedures
1. Lay the life preserver flat, and completely deflate the chamber by using a
vacuum source. If a vacuum source is not available, deflate by depressing
the oral valve while rolling up and squeezing the life preserver. When
rolling the chamber start from the ends and roll towards the valve, while
depressing the oral valve. When completely rolled, first release the valve,
then unroll the life preserver. The life preserver should be thoroughly
evacuated.
1.Insert the first arm into the life preserver between the back strap and the
front cover, then pull over the shoulder.
2.Insert the second arm into the other side of the life preserver.
3.Fasten the waist belt.
4.Pull the inflator pull cord (located at the right front cover) sharply
downwards to activate inflation.
2. Pack the inflation cell back into the cell enclosure; shown in Figure 4.
3. Ensure that the CO2 cylinder is fully charged, tested, and ready for
activation, with its safety clip in place.
NOTE: If required, the life preserver oral inflation valve is
located on the left front cover of the life preserver.
4. Loosen the waist belt by feeding all excess webbing back into the waist
belt adjuster, as shown in Figure 5a.
5.Tighten the waist belt adjuster by pulling the excess webbing of the belt.

dry in front of a radiator or other source of direct heat. Do not
store in a wet condition.
b) To tighten the waist belt, pull excess belt as shown above.
To launder your inflatable:
1. Remove the CO2 gas cylinder.
2. Hand wash or sponge down the fabric in warm soapy water, then rinse
with clean water. If machine washing use the gentle cycle with a mild
detergent or soap.
Figure 6: Packing Procedures
3. Hang to dry in a well-ventilated area, which is free from direct sunlight.
A plastic coat hanger would be preferable to clothes line clips, so that the
life preserver material is not wrinkled or damaged when wet. Do not
tumble dry.
4. To avoid premature aging of the nylon buoyancy cell and stitching, the life
preserver should not be hung in direct sunlight for extended periods of
time. To avoid mildew hang dry the life preserver after every use, and be
sure not to roll up the product or stow it away while damp.

1. Inflatable Cell Test
The inflatable cell can be inflated by the oral inflation valve or the CO2
inflation valve. The inflatable cell is to be tested by the following method:
a. Inflate the cell slowly; the cell shall fully inflate so that it opens the cover
and becomes rigid. Leave the cell fully inflated for a period of 6 hours. At
the end of the 6 hours the cell shall still feel hard to the touch and maintain
its general rigidity.

c. If no leaks are detected from the inflation cell, check for leaking valves
as detailed in the CO2 and Oral Inflation Valve Tests listed below.
d. Upon completion of these tests, if any of the minimum requirements
have not been conformed to, the life preserver shall be returned to your
Mustang Dealer.
2. Oral Inflation Valve Test
The oral inflation valve shall be tested for leaks with the appropriate
inflatable cell inflated to a pressure of 2 psi. The procedure is as follows:
a. Place a small amount of soap and water solution to the valve stem
opening, using care to prevent the entry of water into the valve. Leakage
will be indicated by the bubbling of the soap solution.
MAINTENANCE, INSPECTION
AND TESTING PROCEDURES
Your life preserver should be inspected and tested annually to maintain all compo-
nents of the life preserver, and its associated equipment in a serviceable condition,
and to ensure that the inflatable cell will withstand the specified pressure. For life
preserver that are in use, a more frequent interval is required. Full inspections are
to be performed only by authorized service technicians, but you may perform the
following tests, prior to using the life preserver and on a regular basis thereafter,
to ensure minimum safety precautions are met.
b. Lower the pressure in the inflatable cell and blow by mouth through the
oral inflator valve by pushing the valve inwards to open the air passage.
The effort required to inflate the chamber shall not be excessive, and it
must close tightly when blowing has ceased.
c. The valve shall be considered damaged if it fails either test and the life
preserver must be returned to your Mustang Dealer for servicing.

3. CO2 Inflation Valve Test
d. Insert the CO2 gas cylinder, small end down, and screw into the
threaded hole on the inflator.
To test the CO2 inflation valve, operate the manual lever several times.
Ensure the lever moves fully and that the piercing pin travels far enough to
puncture sealing disk. Visually check to see that the piercing pin is in place,
and protrudes sufficiently. Ensure the piercing pin is erect, and does not bend
to one side.
e. Fold the collar and fasten the Velcro® tabs.(See figure 4: Folding
Procedures)
Make sure that the pull cord with its pull knob is hanging freely
below the inflator and that the red caution flag is not visible.

Inspection Procedures
6. Check the Sea Light system expiry date, if the system has expired remove
it from the suit, and follow the instructions in line (g) below, otherwise
proceed as follows. Check:
1.Unpack the life preserver and lay it flat on a clean, dry, smooth surface.
2.Visually examine the life preserver for signs of damage or missing
components. Visually inspect for the following:
a. punctures, abrasions, or holes to the protective collar or the
inflatable cell;
b. broken or missing fasteners and hardware;
c. loose, damaged, or missing thread;
a. the light dome for cracks,
b. the battery pack casing for cracks and damage,
c. the power cord and plug for damage and corrosion,
d. the cell for deterioration, i.e. swelling
e. the operation of the circuit and bulb, by applying 1.5 volts across the
leads. The bulb should light under these conditions; if it does not light
renew the bulb or the entire unit.
d. corrosion to metal fittings;
e. condition of the CO2 pull cord
f. the fitting of the rescue light. If the existing rescue light is to be replaced
follow these procedures for fitting the new light:
3.Test the mechanical and/or the oral inflator mechanism, where applicable,
by performing the CO2 Inflation Mechanism Test and/or the Oral Inflation
Valve Test.
i) Remove the existing light, and remove the Velcro® patch from
the back surface of the bulb.
ii) Test the new circuit and bulb by procedure (f) above.
iii) Adhere the Velcro® patch to the new bulb using contact cement.
iv) Ensure plugs are secure in battery.
4.Perform the Inflatable Cell Test.
v) Wrap the extra lead around the battery, and push the battery into
the left side pocket of the life preserver
5.Check the inflator before use. As a safety precaution it is recommended
that you check that the inflator is complete, armed, and ready for use. To
do this, follow these simple instructions:
a. Open the front flap on the right front cover on the MD1127, to expose
the inflator.
b. Unscrew and remove the CO2 gas cylinder from the inflator and inspect
the small end of the CO2 gas cylinder. If the end is pierced, the CO2 gas
cylinder is empty and must be replaced (see Figure 7).
c. Make sure the lever on the inflator is in the up or “ready” mode with the
red safety indicator clip in position. If the lever is in the down or “fired”
position, it must be reset into the “ready” position and the red safety clip
installed before inserting the CO2 gas cylinder.
7. Inspect the Whistle:
a. for cracks or signs of wear or damage to the casing
b. Check the operation of the whistle by blowing the whistle several times,
the sound should be clear and not muffled.
c. If either the whistle shows signs of damage, or the sound is
unsatisfactory the whistle is to be replaced, and a new whistle tested.
8. To obtain the maximum benefit from your life preserver it is recommended
that you become familiar with its flotation characteristics. (See Figure 8) Test
it by standing in water chin deep and inflating the buoyancy cell. Lift your
feet off the bottom and note how you float in various positions and water
conditions. Preferably practice this a number of times wearing different types
of bulky and lightweight clothing until you have absolute confidence in your
life preserver’s performance.
CAUTION: Moving the lever into the up or “ready” position after
the CO2 gas cylinder is in place will cause the CO2 cylinder to
discharge into the buoyancy cell.
