- For 22 min generators (PN 117042-2X), fully interchangeable containers manufactured in

Lübeck, Germany by B/E Aerospace will be delivered. Alternatively, replacement generators

manufactured in Lenexa, US can also be ordered. They will fit directly in the current

containers and will not need any adaptation such as the 15 min ones. The 22 min generator

PN remains the same. Instructions for this replacement are given in the AMM task “Ref. 4 and

5”.

If an operator has generators PN 117042-XX in stock, with a manufacturing date of 2005 or later, they

may be used as well (generators with manufacturing date before 2005 shall not be used).
