I just would like to add small comment as below: 1- AD 2009-21-10 has a combined list of affected SN at table 3 which not sorted by ASSY PN as Zodiac VSB 6084-34-35-01 table 2 attached. 2- By comparing cylinder SN at AD 2009-21-10 table 3 and cylinder SN at VSB 6084-34-35-01 table 2 found Some SN missing at VSB, such as ST 82366 & ST 82373. So it will be great if FAA reviewing SN list at AD and write it as the same way as Zodiac VSB 6084-34-35-01 table 2 " i think it is more easy and acuurate".
