27 FAA-2007-28413-0005 1 union_alias 803847f5 2007-09-26T04:00:00Z 0 Air New Zealand Ltd. •Bulletin SB 73-0326 is incorrectly identified. •When Air NZ found that SB 73-0326 Rev 00 was not successful in preventing leaks we issued our own inspection document that required replacement of all clamps with new parts at each inspection. This document is approved by the local regulator. All engines in the fleet had the clamps replaced with new items in a three month program. The NPRM Table 1 currently gives credit for this program, however the “differences between the proposed AD and the Manufacturer’s Service Information” section of the NPRM states that credit is given for “new loop clamps installed at last shop visit”. Air NZ requests that it is made clear that credit is given for all new clamps installed whether at shop visit or on-wing. •In discussions the OEM has indicated that Teflon tape under clamps has not yet been proven to extend the durability of the clamps. Air NZ has been applying Permacel P421 Teflon tape (in lieu of the abrasive fibreglass tape per SB 73-0326) under all new clamps under our own authority. We request that the AD recognises that new clamps may have been installed with Teflon tape and allows those engines to continue to the next inspection without any limit or penalty. •Air NZ has also seen clamp wear on P/N 1303M31G10 and 1303M32G10 fuel manifolds and believes that the wear issues are common to both styles of manifolds. Air NZ will apply the AD requirements to both styles of manifold.         FAA-2007:2007-01-01:2007-12-31
