## Lotus cc:Mail for 9-ANM-NPRMCOMMENT

cc: jpo@cct.condor.de Priorily: Normal Subjecl:Docket No. 2002-NM-12-AD

Dear Ladies and Gentlemen,

After review of Docket No. 2002-NM-12-AD Condor Flugdienst, Germany (CDF) requests a re-evaluation of the proposed rule.

In conformance with Boeing Service Letter 757-SL-24-069, 767-SL24-047 and on, all applicable Static Inverters must be modified to prevent an overheat condition which can result in smoke in the flight deck and the cabin. The Service Letter refers to Avionic Instruments Inc. Service Bulletin 1-002-0102-1000-24-24 which advises a modification to
some electronic devices. After modification the Mod Label has to be marked with a Mod Level Identifier, i.e. letter "BI1. 

## Depending on the Static Inverter 

## part number and dash-number the Mod Level Identifier may be different.

From our point of view the identification by a letter without changing the basic partnurnber is a critical issue.

We believe the only sate and practicable solution would be a defined partnumber change wich excludes the possibility of partnumber mix up and to maintain the partumber tracebility.

Condor would appreciate, if you could pick up this comment to your proposed rule making discussion.

Thanks and

Best Regards,

Christof Ickstadt
