Plain English Summary

2/10 complexity

Requires electrical bonding of specified metal ferry fuel tanks (P/N 330A 871310.00–.04) fitted to AS 332 C/C1/L/L1/L2 helicopters, in accordance with Eurocopter Service Telex No 28.00.44. If installed, bonding must be done before the next refuelling; if not installed, before installation.

CASA cites a French safety alert that an unbonded electrostatic ground connector could allow an arc and cause a tank explosion. Operators or maintenance organisations must perform (or pay for) the bonding and comply with the service telex by the directive’s effective date.

AD/S-PUMA/37 Ferry Fuel Tanks 9/2000 DM

Applicability: AS 332 C, C1, L, L1 and L2 helicopters, metal ferry fuel tanks, part number 330A 871310.00, .01, .02, .03 and .04.

Requirement: 1. For installed metal ferry fuel tanks - Electrically bond the fuel tanks in accordance with paragraph C.C of Eurocopter Service Telex No 28.00.44 dated 6 June 2000.

For metal ferry fuel tanks that are not installed - Electrically bond the fuel tanks in accordance with paragraph C.C of Eurocopter Service Telex No 28.00.44 dated 6 June 2000.

Note: DGAC AD 2000-302(A).

Compliance: For Requirement 1 - Before the next refuelling of the ferry fuel tank after the effective date of this Directive.

For Requirement 2 - Before installation of the ferry fuel tank. This Airworthiness Directive becomes effective on 26 July 2000.

Background: The French Direction Generale de L’Aviation Civile has advised that an electrostatic ground connector on several ferry fuel tanks was not electrically bonded to its support. During refuelling of a tank, the absence of this electrical bonding could generate an electrical arc between the refuelling nozzle of the tanker and the fuel tank causing the fuel tank to explode.
