    The Federal Aviation Administration today published an Airworthiness Directive (AD) that requires users of certain Halon 1211 fire extinguishers to take the following action within 90 days of January 20, 2010 (by April 20, 2010) due to safety concerns stemming from contaminated extinguishing agent contained in certain extinguishers manufactured by Fire Fighting Enterprises, Limited. Click here for a pdf of the AD.

     

    This AD comes on the heels of an EASA (European Aviation Safety Agency) Emergency Airworthiness Directive concerning the same issue, dated November 25, 2009. The contaminated agent may pose a problem due to lack of fire-fighting effectiveness, toxicity or both.

     

    The AD, entitled 2010-01-03 Fire Fighting Enterprises Limited, contains the following requirements:

     

    (1) Within 90 days after the effective date of this AD, replace portable Halon 1211 (BCF) fire extinguishers manufactured by Fire Fighting Enterprises Limited with serviceable fire extinguishers; except as provided by paragraph (g)(2) of this AD.

    (2) Fire extinguishers identified in paragraphs (g)(2)(i) and (g)(2)(ii) of this AD are not required to be replaced.

     (i) Fire extinguishers conclusively determined to have been most recently filled with Halon 1211 supplied by a company other than LyonTech Engineering Limited.

     (ii) Fire extinguishers that have been most recently filled by LyonTech Engineering Limited and that are conclusively determined by Fire Fighting Enterprises Limited to be filled with Halon 1211 that meets their design specification for Halon purity.

    (3) As of the effective date of this AD, do not install any portable fire extinguisher manufactured by Fire Fighting Enterprises Limited unless it has been conclusively determined that the last time it was filled, it was filled with Halon 1211 supplied by a company other than LyonTech Engineering Limited; or it has been conclusively determined by Fire Fighting Enterprises Limited that the last time it was filled, it was filled with Halon 1211 that meets their design specification for Halon purity.
