Attention:

Subject: Comments Related to AD NPRM Docket No. 2002-NM-12-AD

Dear Sir.

This letter provides Avionic Instruments formal comments related to the pending AD associated

with the subject NPRM Docket No. 2002-NM-12-AD.

1. Compliance Time

Avionic Instruments, Inc. (AI') estimates that approximately 3,200 static inverters will require

implementation of Service Bulletin 1-002-0102-1000-24-24. AI' can process approximately 100

units per month. Therefore, a 42-month compliance time period is requested.

2. Cost for Modification at Avionic Instruments

Units returned for implementation of SIB 1-002-0102-1000-24-24 will require an S 875. re-test/recertification charge. This cost does not include roundtrip freight andlor incoming customs

clearance charges.

3. Obsolescence of AI' PIN 1-002.0102-0265 (Boeing PIN S282T004-5)

For reasons of parts obsolescence, ex1ended field usage and an old last-production date, ainines

will be requested to upgrade these units to the latest 777 performance standard (AI' PIN 1-002-

0102-1000, Boeing PIN S282TOO4-10). A speciel exchange program is currently in piece that

affords operators a significant discount off of the replacement cost for a new inverter. The net

cost for this exchange is approximately $ 15,000. Details can be provided upon request.
