EASA EMERGENCY AIRWORTHINESS DIRECTIVE 

AD No.: 2007–0082-E 

Date: 27 March 2007

No person may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the 

requirements of that Airworthiness Directive unless otherwise agreed with the Authority of the State of Registry.

Type Approval Holder’s Name: 

EUROCOPTER 

Type/Model designation(s): 

AS 332 and SA 330 helicopters 

TCDS Number: EASA R.002 

Foreign AD: Not applicable 

Supersedes: Not applicable 

ATA 76. Engine Controls – Fuel Shut-Off Control Lever 

– Check / Reconditioning 

Manufacturer(s): EUROCOPTER (Formerly EUROCOPTER FRANCE, AEROSPATIALE). 

Effectivity: AS 332 C, AS 332 C1, AS 332 L, AS 332 L1 and AS 332 L2 helicopters and 

SA 330 F, SA 330 G and SA 330 J helicopters, all serial numbers. 

Reason: 

This Emergency Airworthiness Directive (EAD) is issued following two 

reports of jamming of one of the fuel shut-off control levers discovered 

during maintenance scheduled check of these controls. 

This jamming originates from the relevant tangential gearboxes. In both 

cases, the grease in the left tangential gearbox solidified and in one of the 

two cases, the right tangential gearbox showed traces of extensive 

corrosion. 

This may be an unsafe condition in case of an aircraft emergency as 

jamming of the fuel shut-off control prevents: 

- the fuel cock at the engine inlet from closing and may thus maintain a fire, 

- the engine compartment ventilation flap from closing, which can reduce 

the efficiency of the extinguishing agent, in the event of firing after fire 

alarm, 

- operation of the general cut-off control so that switching-off the electrical 

power system may become impossible if needed. 

This EAD therefore requires operators to carry out a functional check of the 

fuel shut-off controls and to recondition and grease the tangential 

gearboxes. 

Effective Date: 29 March 2007

according to § 3 below, then, 

1.2 Within 6 months, check and grease-lubricate the tangential 

gearboxes in accordance with the accomplishment instructions 

given in § 2.B.2 of the referenced ASBs corresponding to the 

aircraft version. 

2 – Helicopters which are less than 4 years old: 

2.1 At the latest when the helicopter is 4 years old, check the fuel shutoff controls for correct operation, in accordance with the 

accomplishment instructions given in § 2.B.1 of the referenced 

ASBs corresponding to the aircraft version and analyze the results 

according to § 3 below, then, 

2.2 At the latest when the helicopter reaches 4 and a half years, check 

and grease-lubricate the tangential gearboxes in accordance with

3 – Interpretation of the results. 

3.1 If there is no hard point in the fuel shut-off controls, pending 

compliance with § 1.2 or § 2.2 above, repeat the check of § 1.1 

above for helicopters which are 4 years old and older, or the check 

of § 2.1 above for helicopters which are less than 4 years old, at 

intervals not exceeding 50 FH. 

3.2 If there is a hard point in one of the fuel shut-off controls, before 

resuming flights, comply with § 1.2 above for helicopters which are 

4 years old and older, or § 2.2 above for helicopters which are less 

than 4 years old.
