             Note 2:  EASA EAD 2006-0286-E cancelled and superseded EASA EAD
             2006-0261-E.  AD/ECUREUIL/121 and AD/SA 315/1, which were based on EASA EAD 2006-0261-E, have also been cancelled.
             This Amendment becomes effective on 10 April 2007.
Background:  The original issue of this Directive was issued following information concerning the risk of high-pressure oxygen cylinder rupturing causing rapid venting of the contents.  These cylinders are used for missions at high altitudes or to ensure respiratory aid for passengers feeling sick.

             It has been demonstrated that the material characteristics of the Aluminium Alloy 5283 from which the cylinders are manufactured deteriorate in the course of time and may possibly lead these oxygen cylinders to tear and abruptly vent onboard an aircraft.
             Amendment 1 of this Directive was issued to correct a typographical error.

   This Amendment primarily extends the compliance by six months for aircraft operated in normal climatic conditions and having already accumulated 25 years TIS, as of the effective date of this Amendment.  The Amendment also allows seven days after the effective date to identify and, if necessary, empty spare cylinder, it also introduces some minor formatting changes.
   Amendment 1 of this Directive became effective on 29 September 2006.
   The original issue of this Directive became effective on 26 September 2006.
