Airworthiness Directive · Amendment 39-19870 · Fuel storage
Airbus Helicopters
This AD applies to Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, and AS332L2 helicopters, certificated in any category, except those with modification 0726383 installed.
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, and AS332L2 helicopters. This AD requires removing the drain plugs from the fuel tank compartments located under the bottom structure. This AD was prompted by the discovery that a modification to the fuel tank could lead to fuel accumulating in an area containing electrical equipment and subsequent ignition of fuel vapors. The actions of this AD are intended to address an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Within 110 hours time-in-service or during the next scheduled maintenance, whichever occurs first:
(1) For Model AS332C and AS332C1 helicopters, remove the 6 fuel tank drain plugs by following the Accomplishment Instructions, paragraph 3.B.2. of Airbus Helicopters Alert Service Bulletin No. AS332-53.01.62, Revision 1, dated May 28, 2019 (ASB AS332-53.01.62), except you are not required to place the drain plugs in stock.
(2) For Model AS332L, AS332L1, and AS332L2 helicopters, remove the 7 fuel tank drain plugs by following the Accomplishment Instructions, paragraph 3.B.2. of ASB AS332-53.01.62, except you are not required to place the drain plugs in stock.
