» SAR 

Search and Rescue crews will make good use of the AW139's greater cruise speed and higher useful load, wh1le the aircraft's 

exceptional OEI capability will bring added confidence during rescues at sea . The aircraft's ability to reduce pilots' workload and 

operate in even the harshest environments will ensure SAR crews achieve their missions safely 

» EMS 

The internal dimensions of the large and unobstructed cabin of the AW139 makes it the best choice for primary and secondary 

EMS applications. The flat floor and ceiling provide maximum cabin flexibility for easy reconfiguration . An 8 cu . m cabin volume 

and a height of 142 m al lows the medical attendants easy access to casualties. Litter layout ranges from two to four 

in MEDEVAC configuration. 

» LAW ENFORCEMENT 

The AW139 sets a new standard in the Law Enforcement intemediate helicopter market by surpassing all others in this weight 

class in versatility, performance, productivity . Developed to exceed the rigorous standards of federal , state and local airborne 

law enforcement authorities, the AW139 Law Enforcement aircraft achieves this by utilizing the most efficient, proven and 

advanced technologies and design criteria to achieve a very cost-effective helicopter. The integrated avionic system provides 

the basis for managing the sensors and comprehensive communications suite required for the law enforcement role. 

» CORPORATENIP 

The AW139's refinement is matched by the highest standards in style and comfort. The spacious cabin provides flexibility for 

the most sophisticated requirements . The AW139's baggage compartment, the largest in its class, can accommodate a wide 

range of cargo for business or personal flights . The AW139's interior materials are the finest available, selected not only for 

beauty and value, but also to enhance the experience of flying. 

»HARBOUR PILOT SHUTTLE 

With excellent handling and outstanding OEI performance the AW139 is ideally suited to the harbour pilot shuttle role as well as 

other maritime support tasks.

3.10 Manually turn and hold the fi xed swash plate (2) ful ly clockwise. Make sure that the dial gauge indication goes back to 

"0". If not, do Step 3.5 thru Step 3.9. 

3.11 Remove the extension, the dial gauge (4), the support arm and the support from the helicopter 

4 If the total play recorded at Step 3.9 is more than 3.0 mm (0.12 in), do the operations that follow: 

4.1 Remove the swashplate Refer to 39-C-62-31-06-00A-520A-A 

4.2 Do a visual examination of the centering plates for condition and damage. If you find that the centering plates are 

damaged, replace them. Refer to 39-C-62-31 -05-00A-520A-A and 39-C-62-31-05-00A-720A-A 

4.3 Do a visual examination of the internal surfaces of the swash plate for condition and damage. If you find that the 

intern al surfaces of the swash plate are damaged, replace the swash plate. 

4.4 Install the swashplate. If necessary, use a new swashplate. Refer to 39-C-62-31 -06-00A-720A-A 

5 Get access to the rotor-brake control panel on the overhead panel in the cockpit 

3 Apply the rotor brake. To do this, move the rotor-brake control lever from OFF to BRAKE. 

7 Make sure that the main rotor head is locked. 

8 Get access to the main rotor head. 

9 Measure the play of the rotating scissors (9, Fig 2). Obey the instructions that follow: 

9.1 Lock the Support (Support Equipment Ref. 6) (1) on the main rotor head (2). 

9.2 Connect the Support Arm (Support Equipment Ref. 3) (3) to the support ( 1 ). 

9.3 Lock the Extension (Support Equipment Ref. 4) (6) and the Dial Gauge (Support Equipment Ref. 5) (5) at the end of 

the support arm (3). 

9.4 Put the plunger of the extension (6) against the head of the bolt (7). To do th is, adjust the position of the support arm 

(3) as necessary. 

9.5 Set the dial gauge indication to "0". 

9.6 Try to turn the rotating swashplate (4) clockwise and read the dial gauge (5). The value you read on the dial gauge is 

the total play of the rotating scissors. 

9.7 Record the total play shown by the dial gauge (5). 

9.8 Remove the extension (6), the dial gauge (5), the support arm (3) and the support (1) from the helicopter. 

10 Make sure that the total play recorded at Step 9.7 is not more than 4.5 mm (0.18 in). 

11 If the total play recorded at Step 9. 7 is within the specified limit, continue with Step 12. 7. 

12 If the total play recorded at Step 9. 7 is more than the specified limit: 

12.1 Do a check for an unusual axial play of the bottom rotating scissors (8). To do this, manually move the bottom rotating 

scissors some times along the axis of the spherical bearing. 

12.2 If you find an unusual axial play of the bottom rotating scissors (8) Do a detailed inspection of the bottom rotating

12.7 Make sure that the beads of sealing compound on the top and bottom rotating scissors are not damaged. 

Note 

For the location of the beads of sealing compound on the top and bottom rotating scissors refer to Fig 3. 

12.8 If the beads of the sealing compound are damaged, replace them. Refer to 39-C-62-31-00-00A-920A-A. 

12 9 Install the rotating scissors (9) on the helicopter. Refer to 39-C-62-31-02-00A-720A-A. 

Requirements after job completion 

Remove all the tools and the other items from the work area. Make sure that the work area is clean.
