### Approved under EASA DOA No. 21J.056 Page 5/36

2011.07.06 Revision 3 of this ALERT SERVICE BULLETIN will form the subject of an EASA Airworthiness Directive, except for the limit dat e for installation of new hoist beam lower fitting protectors, which is now set at July 31, 2011 in this ALERT SERVICE BULLETIN, but which will remain unchanged in the new EASA Airworthiness Directive with respect to EASA Airworthiness Di rctive No. 2009-0271.



### 1.D. DESCRIPTION

Revision 0:

EUROCOPTER has received a report of hydraulic hois t cable jamming at the hoist beam lower fitting (a) (double hoist plate installation - zone Z shown on photo 4). The jamming occurred during a hoisting operation at sea, during the cable raisin g phase while the load was swinging heavily. As the helicopter was fitted with an auxiliary electr ic hoist, it was possible to complete the hoisting operation.

During the investigations conducted by EUROCOPTER following this event, three conditions were identified which could jeopardize safety:

1) For all the helicopters mentioned in paragraph 1.A.1.:

Operating the hoist control in the up or down direct ion after the main hoist cable has jammed in zone Z (shown on photos 3 and 4) can lead to the failure of this cable due to mechanical chafing on the fitting.

To correct this condition, which could jeopardi ze safety, this ALERT SERVICE BULLETIN renders compliance with the hoisting instructi on defined in paragraph 2.B.1. mandatory.

For SUPER PUMA helicopters: This ALERT SERVICE BULLETIN makes the installation of a hoist beam lower fitting protector mandatory, in order to cancel this hoisting instruction.



### NOTE 5

This hoist beam lower fitting protector is incompatible with SUPER PUMA helicopters equipped with a RH side sliding door P/N 332A22-1165-01 as it would prevent this door type from opening. Another protector for these helicopters will be proposed at part of a subsequent revision to this ALERT SERVICE

BULLETIN.

For PUMA helicopters: To cancel th is hoisting instruction, a protec tor will be proposed to you in a subsequent revision of this ALERT SERVICE BULLETIN.



### NOTE 6

The protector defined for SUPER PUMA helicopters cannot be installed on PUMA helicopters as it would prevent the door from opening.

### Approved under EASA DOA No. 21J.056 Page 6/36

2011.07.06 2) For helicopters mentioned in paragraph 1.A.1., fitte d with an auxiliary electric hoist whose electrical power supply harness is locat ed in zone Z, shown on photo 3:

There is a risk of interference between the hydraulic hoist cable and the auxiliary hoi st electrical harness, which can lead to damage to this electr ical harness and cause a short circuit when the auxiliary hoist is energized. This short circuit ca n cause the main hoist cable to melt and fail.

To correct this condition, which could jeopardize safety, this ALERT SERVICE BULLETIN makes the installation of a hoist beam lower fitting protector mandatory. Pending installation of this protector, this ALERT SERVICE BULLETIN renders complia nce with the hoisting instruction defined in paragraph 2.B.1. mandatory.

The double and single hoist installations are shown respectively on photos 1 and 2.

Revision 1:

3) For helicopters, mentioned in paragraph 1.A.1., not fitted with the hoist beam lower fitting protector

and on which the hoist control electrical harne ss is routed in zone Z, shown on photo 3.

In this configuration, the hoist cable may cause dam age to the hoist pyrotechnical squib firing control

electrical harness and thus cause untim ely firing of the pyrotechnical squib.

To correct this condition, which could jeopardi ze safety, Revision 1 of this ALERT SERVICE BULLETIN makes the removal of the squib and installa tion of two placards (in the cockpit and cabin) mandatory, pending installation of the hoist beam lower fitting protector.

Revision 2:

For industrialization reasons, the components comp rising the definition of the hoist beam lower fitting protector for SUPER PUMA helicopters equipped with a RH side sliding door P/N 332A22-1165-01 and for PUMA helicopters, cannot be developed and therefore not be installed before December 31, 2009. Consequently, for these helicopt ers, the limitations defined in paragraph 2.B.1.

and 2.B.3. of this ALERT SERVICE BULLETIN ar e extended until June 30, 2011, to enable a hoist beam lower fitting protector to be installed.

Revision 3:

The hoist beam lower fitting protectors for SUPER PU MA helicopters equipped with a RH side sliding door P/N 332A22-1165-01 and for PUMA helicopters have been defined.

To cancel the hoisting instructions defined in parag raph 2.B.1. and 2.B.3., Revision 3 of this ALERT

SERVICE BULLETIN renders the inst allation of a hoist beam lower fitting protector mandatory on all helicopters specified in paragraph 1.A. 1., at the latest by July 31, 2011.

### 2.B. OPERATIONAL PROCEDURE

2.B.1. Hoisting instructions

IF THE HOIST CABLE JAMS IN ZONE Z (PHOTOS 3 AND 4) OF THE HOIST BEAM LOWER FITTING,
POSSIBLY SUBSEQUENT TO THE CABLE SWINGING HEAVILY, DO NOT OPERATE THE HOIST CONTROL, NEITHER IN THE UP OR DOWN DIRECTION, TO REDUCE THE RISK OF DAMAGING THE CABLE, WHICH COULD CAUSE IT TO FAIL.

- Make a placard with the following wording (red text on white background) and affix it in a visible

position, near the hoist operator station:

IF THE CABLE JAMS IN THE HOIST BEAM LOWER

FITTING. DO NOT ATTEMPT TO RAISE OR LOWER

THE LOAD.

# CHAPTER 4

"Normal Procedures " (approved part)

The hoist cable cannot be cut using the PILOT’s an d COPILOT’s control, it is therefore mandatory before any hoisting mission, to make sure that the radio-communication between the pilot and the hoist operator is of good quality in the flight c onditions (before performing any hoisting operation), and

that the hand shears are within t he reach of the hoist operator.
