a)135M-200 Floor Pallet Assy. 

The floor pallet assembly is constructed of 1/4" Nomex Honeycomb with a decorative overlay. 

The floor is designed to be sacrificial in absorbing impacts that wouldnormally damage the 

airframe floor. The floor incorporates an aluminum blood dam to prevent fluids from entering 

other areas of the aircraft. There is no structural function to this assembly. 

b)135M-300 Litter Installation 

The basic litter installation can be installed either on the right or left side of the 

cabin. The litter is a modified Femo Washington Model 1123. The litter assembly 

is modified by the addition of the Metro Aviation posi-lock latching mechanism 

consisting of a receiver and latching mechanism attached to the litter assembly 

and a plate with alignment and securing studs attached to the existing cabin. 

F A A A p p r o v e d 6 I 3 o I 2 o 1 o 
aircraft, the load path is directly from the harness to the primary airframe structure. This 

installation can be configured for RH, LH or both per customer request. 

c) 13 SM -41 0 Seating Installation LH 

The seating installation incorporates the standard manufacturer supplied seat. The seat is used both in aft and forward facing positions in the original installation. 

To adapt the aft cabin to EMS work, it was necessary to face the seat aft and relocate the seat out 

board approximately 611 and forward approximately 611 • To accomplish this, new 

seat attachment hardware was added to the airframe floor for the inboard seat 

legs. Additional structure was added to provide a suitable mounting surface 

for the outboard legs by replacing the original access panels with structural 

honeycomb material. The additional material connects the existing airframe floor/ 

keel beam junction to the exterior shell and door frame structure. The manufacture 

supplied seat is not modified. This installation may be removed and the 135M-430 

Simula seat installed in lieu ofthis seat. 

Optional Equipment Items a) 135M-I 50 Avionics Shelf Modification 

The aircraft can be provided with an Avionics shelf installed as an option. This 

modification relocates the forward edge of the shelf upwards 311 to allow for 

easier access to the AFT cabin area. The existing airframe hardware and shelf 

is unchanged. The 3 II lift is obtained by installation of an offset hinge connecting 

the shelf with the airframe at the forward pivot point. The shelf is rated for 70kg 

(154lbs) from the manufacturer. The modification does not require amendment 

ofthat load rating.

the litter is rolled aft. 

There are two additional options for use in this position. The 135M-3500-l utilizing the Femo 

Model 28Al Red Legs) gurney as an alternate to the 28A. The Ferno 28Al provides a more 

durable and stable frame for ground use. Operation is identical to the 28A. 

The 135M-3500 IT-I, Gurney assembly may be used to support specialty medical equipment. 

The unit is provided with a smooth flat top for attachment of other equipment. The attachment or 

placement of equipment is to be approved separately by other approvals or as canyon equipment 

by the owner/operator of the aircraft. This unit is weight limited to 170 pounds exclusive of the 

gurney basic weight. 

c) l 35M-400 Seat Installation RH 

The seating installation incorporates the standard manufacturer supplied seat. 

The seat is used both in aft and forward facing positions in the original installation. 

To adapt the aft cabin to EMS work, it was necessary to face the seat aft and relocate the seat out 

board approximately 6" and forward approximately 6". To accomplish this, new 

seat attachment hardware was added to the airframe floor for the inboard seat 

legs. Additional structure was added to provide a suitable mounting surface 

for the outboard legs by replacing the original access panels with structural 

honeycomb material. The additional material connects the existing airframe floor/ 

keel beam junction to the exterior shell and door frame structure. The manufacture 

supplied seat is not modified. 

d) 135M-420 Seat Installation AFT 

The aft forward facing seat is a stow able seat incorporating the new Part 27 

standards. In the normal down position, the seat is secured overhead through a hinged 

system to a manufactured beam assembly attached to each side of the cabin primary structure, 

and to the aircraft floor through the RH litter posi-lock mount base which is secured to the 

aircraft existing seat and cargo rails. There isa four-point inertia real harness system that ties into 

the beam assembly for the shoulder hamess and to the posi-lock plate for the lap belt, essentially 

eliminating any attachment loads on the seat. 

F A A A p p r o v e d 6 I 3 o I 2 o 1 o 
from the posi-lock plate and stowed with the seat. 

The seat is designed to allow the aircraft to be configured from a 3 attendant 1 patient 

configuration to a 2 attendant 2 patient configuration by the flight crew within 30 seconds and 

not relocating or removing equipment requiring significant weight and balance changes.

The oxygen system is based on the Scott Ambassador Transfill System found in most cabin class 

fixed wing aircraft and also used by Metro Aviation for 10 years in all of our STC'ed 

installations. This system has been adapted to EC135 by mounting the 76.5 cubic ft. bottle to the 

exterior of the fuselage right hand side. The bottle is placed in between the cross tubes and below 

the door tracks and has Aerodynamic composite cover. The bottle is not below the lowest belly 

line to prevent damage to the bottle in the event of a hard landing where the belly contacts the 

ground. Low pressure oxygen is supplied to the cabin though 1/4" seamless stainless steel lines 

to self contained Essex regulator/outlet assemblies. The low pressure system can be cut off at the 

point where it enters the aircraft by an electrically controlled shut off valve. The valve can be 

controlled by the medical crew or the pilot with the pilot control having priority. The contents of 

the bottle can be monitored on a gauge in the cabin supplied by a 1116" seamless stainless steel 

capillary line. Filling of the bottle will be through a calibrated port located adjacent to the bottle. 

i) 135M-610 Oxygen System (current) 

The oxygen system is based on the Scott Ambassador Transfill System found 

in most cabin class fixed wing aircraft and also used by Metro Aviation for 1 0 

years in all of our STC'ed installations. This system has been adapted to EC135 

by mounting the 76.5 cubic ft. Kevlar wrapped bottle to the exterior of the fuselage right hand 

side. The bottle is placed in between the cross tubes and below the door tracks and has 

Aerodynamic composite cover. The bottle is not below the lowest belly line to prevent damage 

to the bottle in the event of a hard landing where the belly contacts the ground. Low-pressure 

oxygen is supplied to the cabin though 114" seamless stainless steel lines to self contained Essex 

regulator/outlet assemblies. The low-pressure system can be cut off at the point where it enters 

the aircraft by an electrically controlled shut off valve. The valve can be controlled by the 

medical crew or the pilot with the pilot control having priority. The contents of the bottle can be

The aircraft can be equipped with the optional left hand external transfill oxygen 

cylinder. The mounting of the cylinder is the same as the right hand cylinder with the 

same aero dynamic cover. The filling of each bottle is done individually with no 

interconnect for servicing of the cylinders simultaneously. 

The contents gauge installed as part of the right hand installation is replaced with a left 

and right pressure transducer with a single digital gauge located in place of the analog gauge. 

The contents of each tank can be checked by depressing the "OXY" switch and 

selecting the left (1) or right (2) system with switch located in the Medical Control panel 

allowing the contents of each bottle to be displayed on the digital display. The shut-off valves 

are normally closed. In the event there is total loss of power from the buses and battery, the 

valves will be closed. There are two emergencyshut-offvalves in the system. The shut-off 

valves can be activated by either the switch located in the medical control panel or the pilot 

priority switch. The pilot switch cannot be over ridden by the medical crew switch position. The 

left and right systems cannot be connected to supply oxygen simultaneously, however, either left 

or right systems when selected will supply all cabin outlets. Filling of the bottle will be through a 

calibrated portlocated adjacent to the bottle. 

k) 135M-640 External Lox System 

The aircraft can be equipped with the optional ESSEX LOX system. The LOX DEW ARS 

container holds 7 liters of liquid oxygen. The mounting of the cylinder is on the right hand side 

of the fuselage externally and covered by a fiberglass fairing. The filling of the DWARS 

container is done by removing the cylinder and servicing away from the aircraft. The contents of 

the tank can be checked by turning the power on and viewing the contents gauge located in the 

Medical Control. There are two emergency shut-off switches in the system. The shut-off valves 

can be activated by either the switch located in the medical control panels or the pilot priority 

switch located in the cockpit overhead switch panel. The pilot switch cannot be overridden by the 

medical crew switch. In the event there is total loss of power from the buses and battery, the 

valves will be closed. Detailed filling instructions can be found in the maintenance manual and 

Instructions for Continued Airworthiness.

to the aircraft powering the outlets in the aft cabin. A visual indication is provided to show the 

crew the external source is connected, the external access door to the receptacle is equipped with 

a switch to notify the pilot if the door is open, indicating the I ine land may still be plugged in. 

Once the aircraft electrical system is operational, the medical inverter is powered 

until one generator/system fails. No over ride is possible. 

An additional switch may be installed, in series with the above access door switch, which 

indicates the proper closure of the clamshell baggage doors. The external access switch and the 

clamshell door switch activate the EPU door caution warning on the CPDS. 

m)l35M-720 Medical Suction System 

A Thomas Industries suction pump is located on the battery deck aft of the 

right engine. The pump is used by the medical crew in the care of the patient 

and controlled through a switch in the aft cabin. Two outlets are provided for 

connection of hospital provided equipment. Regulation is provided through a 

regulator mounted on the 135M-800 gas panel. Once aircraft electrical system 

is operational, the medical suction system is powered until one generator system 

fails. No over ride is possible. 

n)135M-800 Gas Panels 

The gas panels are located on the forward side of frame 5. These panels provide 

a mounting location for the oxygen regulators/outlets and one other similarly 

sized outlet or control assembly. 

o)135M-900 Window Storage 

The left and right window storage pods are designed to optimize lost space in 

the area of the aft cabin windows. The pods fit the contour of the interior paneling 

whi Ie not eliminating any window area. They incorporate a hard pouch area for 

the storage of up to 3 Ibs. of soft goods and also provide a mounting area for 

the installation of medical equipment and outlets. The storage pods are non-structural.
